Because of their design, when a radial load is applied, an axial force component is produced; therefore, two or more opposed bearings must be used.\u003cbr data-mce-fragment=\"1\"\u003e Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools where high running accuracy is required (refer to Chapter 9 Preload on Page A192 for more information).\u003cbr data-mce-fragment=\"1\"\u003e Usually, the cages for angular contact ball bearings with a contact angle of 30° (designation A) or 40°(designation B) are made in accordance with Table 1, but depending on the application, machined synthetic-resin cages or molded polyamide-resin cages may also be used. The basic load ratings given in the bearing tables are based on standard cages.\u003cbr data-mce-fragment=\"1\"\u003e Though the figures in the bearing tables on Pages C086 to C101 for bearing bore diameters of 10 to 120 show bearings with single-shoulder inner rings, dual-shoulder bearings are also available.

Because of their design, when a radial load is applied, an axial force component is produced; therefore, two or more opposed bearings must be used.\u003cbr data-mce-fragment=\"1\"\u003e Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools where high running accuracy is required (refer to Chapter 9 Preload on Page A192 for more information).\u003cbr data-mce-fragment=\"1\"\u003e Usually, the cages for angular contact ball bearings with a contact angle of 30° (designation A) or 40°(designation B) are made in accordance with Table 1, but depending on the application, machined synthetic-resin cages or molded polyamide-resin cages may also be used. The basic load ratings given in the bearing tables are based on standard cages.\u003cbr data-mce-fragment=\"1\"\u003e Though the figures in the bearing tables on Pages C086 to C101 for bearing bore diameters of 10 to 120 show bearings with single-shoulder inner rings, dual-shoulder bearings are also available.

direction together with radial loads. Because of their design, when a radial load is applied, an axial force component is produced; therefore, two or more opposed bearings must be used.\u003cbr data-mce-fragment=\"1\"\u003e Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools where high running accuracy is required (refer to Chapter 9 Preload on Page A192 for more information).\u003cbr data-mce-fragment=\"1\"\u003e Usually, the cages for angular contact ball bearings with a contact angle of 30° (designation A) or 40°(designation B) are made in accordance with Table 1, but depending on the application, machined synthetic-resin cages or molded polyamide-resin cages may also be used. The basic load ratings given in the bearing tables are based on standard cages.\u003cbr data-mce-fragment=\"1\"\u003e Though the figures in the bearing tables on Pages C086 to C101 for bearing bore diameters of 10 to 120 show bearings with single-shoulder inner rings, dual-shoulder bearings are also available.

Because of their design, when a radial load is applied, an axial force component is produced; therefore, two or more opposed bearings must be used.\u003cbr data-mce-fragment=\"1\"\u003e Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools where high running accuracy is required (refer to Chapter 9 Preload on Page A192 for more information).\u003cbr data-mce-fragment=\"1\"\u003e Usually, the cages for angular contact ball bearings with a contact angle of 30° (designation A) or 40°(designation B) are made in accordance with Table 1, but depending on the application, machined synthetic-resin cages or molded polyamide-resin cages may also be used. The basic load ratings given in the bearing tables are based on standard cages.\u003cbr data-mce-fragment=\"1\"\u003e Though the figures in the bearing tables on Pages C086 to C101 for bearing bore diameters of 10 to 120 show bearings with single-shoulder inner rings, dual-shoulder bearings are also available.

direction together with radial loads. Because of their design, when a radial load is applied, an axial force component is produced; therefore, two or more opposed bearings must be used.\u003cbr data-mce-fragment=\"1\"\u003e Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools where high running accuracy is required (refer to Chapter 9 Preload on Page A192 for more information).\u003cbr data-mce-fragment=\"1\"\u003e Usually, the cages for angular contact ball bearings with a contact angle of 30° (designation A) or 40°(designation B) are made in accordance with Table 1, but depending on the application, machined synthetic-resin cages or molded polyamide-resin cages may also be used. The basic load ratings given in the bearing tables are based on standard cages.\u003cbr data-mce-fragment=\"1\"\u003e Though the figures in the bearing tables on Pages C086 to C101 for bearing bore diameters of 10 to 120 show bearings with single-shoulder inner rings, dual-shoulder bearings are also available.

Because of their design, when a radial load is applied, an axial force component is produced; therefore, two or more opposed bearings must be used.\u003cbr data-mce-fragment=\"1\"\u003e Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools where high running accuracy is required (refer to Chapter 9 Preload on Page A192 for more information).\u003cbr data-mce-fragment=\"1\"\u003e Usually, the cages for angular contact ball bearings with a contact angle of 30° (designation A) or 40°(designation B) are made in accordance with Table 1, but depending on the application, machined synthetic-resin cages or molded polyamide-resin cages may also be used. The basic load ratings given in the bearing tables are based on standard cages.\u003cbr data-mce-fragment=\"1\"\u003e Though the figures in the bearing tables on Pages C086 to C101 for bearing bore diameters of 10 to 120 show bearings with single-shoulder inner rings, dual-shoulder bearings are also available.

direction together with radial loads. Because of their design, when a radial load is applied, an axial force component is produced; therefore, two or more opposed bearings must be used.\u003cbr data-mce-fragment=\"1\"\u003e Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools where high running accuracy is required (refer to Chapter 9 Preload on Page A192 for more information).\u003cbr data-mce-fragment=\"1\"\u003e Usually, the cages for angular contact ball bearings with a contact angle of 30° (designation A) or 40°(designation B) are made in accordance with Table 1, but depending on the application, machined synthetic-resin cages or molded polyamide-resin cages may also be used. The basic load ratings given in the bearing tables are based on standard cages.\u003cbr data-mce-fragment=\"1\"\u003e Though the figures in the bearing tables on Pages C086 to C101 for bearing bore diameters of 10 to 120 show bearings with single-shoulder inner rings, dual-shoulder bearings are also available.

Because of their design, when a radial load is applied, an axial force component is produced; therefore, two or more opposed bearings must be used.\u003cbr data-mce-fragment=\"1\"\u003e Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools where high running accuracy is required (refer to Chapter 9 Preload on Page A192 for more information).\u003cbr data-mce-fragment=\"1\"\u003e Usually, the cages for angular contact ball bearings with a contact angle of 30° (designation A) or 40°(designation B) are made in accordance with Table 1, but depending on the application, machined synthetic-resin cages or molded polyamide-resin cages may also be used. The basic load ratings given in the bearing tables are based on standard cages.\u003cbr data-mce-fragment=\"1\"\u003e Though the figures in the bearing tables on Pages C086 to C101 for bearing bore diameters of 10 to 120 show bearings with single-shoulder inner rings, dual-shoulder bearings are also available.

Because of their design, when a radial load is applied, an axial force component is produced; therefore, two or more opposed bearings must be used.\u003cbr data-mce-fragment=\"1\"\u003e Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools where high running accuracy is required (refer to Chapter 9 Preload on Page A192 for more information).\u003cbr data-mce-fragment=\"1\"\u003e Usually, the cages for angular contact ball bearings with a contact angle of 30° (designation A) or 40°(designation B) are made in accordance with Table 1, but depending on the application, machined synthetic-resin cages or molded polyamide-resin cages may also be used. The basic load ratings given in the bearing tables are based on standard cages.\u003cbr data-mce-fragment=\"1\"\u003e Though the figures in the bearing tables on Pages C086 to C101 for bearing bore diameters of 10 to 120 show bearings with single-shoulder inner rings, dual-shoulder bearings are also available.

Because of their design, when a radial load is applied, an axial force component is produced; therefore, two or more opposed bearings must be used.\u003cbr data-mce-fragment=\"1\"\u003e Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools where high running accuracy is required (refer to Chapter 9 Preload on Page A192 for more information).\u003cbr data-mce-fragment=\"1\"\u003e Usually, the cages for angular contact ball bearings with a contact angle of 30° (designation A) or 40°(designation B) are made in accordance with Table 1, but depending on the application, machined synthetic-resin cages or molded polyamide-resin cages may also be used. The basic load ratings given in the bearing tables are based on standard cages.\u003cbr data-mce-fragment=\"1\"\u003e Though the figures in the bearing tables on Pages C086 to C101 for bearing bore diameters of 10 to 120 show bearings with single-shoulder inner rings, dual-shoulder bearings are also available.

inner and outer rings are each integrated into one. These bearings can sustain axial loads in both directions and offer good capacity for sustaining moment loads.
