NSK Self-Aligning Ball Bearings, Cylindrical Bore Bearings 1210 ,D=50   Bearing Numbers Boundary Dimensions (mm) Basic Load Ratings (kN) Limiting Speeds (min-1) Constant e Axial Load Factors Mass (kg) approx. d D B r min.

This type is recommended when the alignment of the shaft and housing is difficult and when the shaft may bend. Since the contact angle is small, axial load capacity is low. Pressed-steel cages are usually used.     PROTRUSION AMOUNT  Some self-aligning ball bearings have balls that protrude from the side face as shown below. This protrusion amount b1 is listed in the following table.         PERMISSIBLE MISALIGNMENT  The permissible misalignment of self-aligning ball bearings is approximately 0.07 to 0.12 radian (4° to 7°) under normal loads. However, depending on the surrounding structure, such an angle may not be possible. Take care in the design of the bearing surroundings.

By using cold- or heat-resistant grease or changing the type of rubber, the operating temperature range can be extended. Compared with conventional bearings: ● Improved reliabilityBearing life is 15% longer than conventional bearings thanks to optimization of the bearing’s internal design and improvement of processing technology. As a result, NSKHPS™ bearings contribute to reducing maintenance costs and facilitate the downscaling of related equipment.● New product lineupThe standard dimensions are identical to standard size bearings. NSK has expanded the lineup of NSKHPS™ bearings by focusing on a wide range of sizes offering a high degree of versatility for various general-purpose applications.
