FAQ

What is the recommended tightening torque for the set screws on the 1090-90G bearing?

For a 90mm bore bearing like the RHP 1090-90G, the set screws are typically M12 or M14. The recommended tightening torque would be in the range of 29-35 Nm, but it is crucial to consult the manufacturer’s specific installation guide to prevent shaft damage or insufficient locking force. Always tighten the screws alternately to ensure even pressure.

Can this RHP Self-Lube bearing be relubricated, and if so, what type of grease should be used?

Yes, RHP Self-Lube bearings like the 1090-90G are typically designed to be relubricatable. They are factory-filled with a high-quality lithium-based grease suitable for a wide range of operating temperatures and speeds. For relubrication, it is best to use a similar NLGI 2 or NLGI 3 lithium complex grease to ensure compatibility. Avoid mixing grease types.

What is the significance of the spherical outer diameter on this insert bearing?

The spherical (convex) outer diameter of the 1090-90G allows it to be mounted in a housing with a corresponding spherical (concave) bore. This design feature permits the bearing to swivel within the housing, accommodating initial static misalignment of the shaft up to a few degrees. This simplifies installation and reduces stress on the bearing caused by minor mounting inaccuracies.
