Features
- Corrosion
Resistance Made of AISI 440C stainless steel, and suitable in a corrosive environment, in clean room and for food machinery. - Aligning
Function Reducing the excess strain on bearing, by aligning the flexure of the conveyor rollerʼs shaft or the error of shaft center. - Dustproof
Available with seals and shields, and suitable in a dusty or watery environment. - Interchangeability
Interchangeable to 6000, 6200, 6300, 1200 and 1300 series bearings.
The dimensions are the same, except the width of the bearing inside. - Heat resistance
Heat-resistant temperature of standard specifications is the same as SS series. - Other
The SH series bearings have more advantages than the standard self-aligning bearings made of SAE 52100 steel.

Precautions
- Recommended fit to housing bore is H class of tolerance range. Please consult with us in case of special use conditions.
- Axial load may impair the aligning function, therefore is not recommended.
- Please refer to the chart below for the recommended tightening torque. Adhesive bond is not recommended. It may damage the bearing.
