NTN Deep Groove Ball Bearings

NTN Deep Groove Ball Bearings 6201, D=12 Bore Type Round Bore Diameter 12 mm, 0.4724 in Outside Diameter 32 mm, 1.2598 in Overall Width 10 mm, 0.3937 in Closure Type Open Internal Clearance CN Operating Temperature Range -40 to 250 ºF Cage Type Pressed Dynamic Load Capacity 1510 lbf Static Load Capacity 620 lbf Precision Rating Class 0 Seal Type None Bearing Material High Carbon Chrome Steel Cage Material Steel Inner Ring Width 0.3937 in, 10.000 mm Outer Ring Width 0.3937 in; 10.000 mm Maximum RPM (Grease) 22000 RPM Fillet Radius 0.600 mm, 0.0236 in Maximum RPM 26000 RPM 1. Design features and characteristics Deep groove ball bearings are very widely used. A deep groove is formed on the inner and outer ring of the bearing enabling the bearing to sustain radial and axial loads in either direction as well as the complex loads which result from the combination of these forces. Deep groove ball bearings are suitable for high speed applications. When two or more deep groove ball bearings are used in combination and mounted adjacent to each other a duplex set (D2) should be used. Duplex bearings (D2) utilize controlled tolerances to more evenly distribute the loading between the individual bearing rows which improves the overall performance of the assembly. In addition to unsealed and unlubricated “open” bearings, NTN provides deep groove ball bearings that are pre-lubricated with grease and enclosed by seals or shields. See section “11. Lubrication” for a list of some of the greases which can be used. Table 1 shows the construction and special characteristics of various sealed deep groove ball bearings.    Types and codes N Shielded type Shielded type Non-contact type ZZ Non-contact type LLB Contact type LLU Low torque type LLH Construction Metal shield plate is affixed to the outside ring; the inner ring incorporates a V-groove and labyrinth clearance.

Design features and characteristics Deep groove ball bearings are very widely used. A deep groove is formed on the inner and outer ring of the bearing enabling the bearing to sustain radial and axial loads in either direction as well as the complex loads which result from the combination of these forces. Deep groove ball bearings are suitable for high speed applications. When two or more deep groove ball bearings are used in combination and mounted adjacent to each other a duplex set (D2) should be used. Duplex bearings (D2) utilize controlled tolerances to more evenly distribute the loading between the individual bearing rows which improves the overall performance of the assembly. In addition to unsealed and unlubricated “open” bearings, NTN provides deep groove ball bearings that are pre-lubricated with grease and enclosed by seals or shields. See section “11.

Deep groove ball bearings are suitable for high speed applications. When two or more deep groove ball bearings are used in combination and mounted adjacent to each other a duplex set (D2) should be used. Duplex bearings (D2) utilize controlled tolerances to more evenly distribute the loading between the individual bearing rows which improves the overall performance of the assembly. In addition to unsealed and unlubricated “open” bearings, NTN provides deep groove ball bearings that are pre-lubricated with grease and enclosed by seals or shields. See section “11. Lubrication” for a list of some of the greases which can be used.

Design features and characteristics Deep groove ball bearings are very widely used. A deep groove is formed on the inner and outer ring of the bearing enabling the bearing to sustain radial and axial loads in either direction as well as the complex loads which result from the combination of these forces. Deep groove ball bearings are suitable for high speed applications. When two or more deep groove ball bearings are used in combination and mounted adjacent to each other a duplex set (D2) should be used. Duplex bearings (D2) utilize controlled tolerances to more evenly distribute the loading between the individual bearing rows which improves the overall performance of the assembly. In addition to unsealed and unlubricated “open” bearings, NTN provides deep groove ball bearings that are pre-lubricated with grease and enclosed by seals or shields. See section “11.
