Pre-Delivery Inspection
Each RB35020 Crossed Roller Bearing is strictly tested for accuracy, smooth rotation, and noise control before shipment. Only bearings meeting all quality standards are cleaned, lubricated, and securely packed for safe delivery.
RB35020 Crossed Roller Bearing – FAQ
Can the RB35020 operate without additional sealing?
While it can function without seals in clean environments, sealing is recommended for dusty or humid conditions to prevent debris and moisture from entering the bearing.
How can I extend the bearing's service life?
Maintain proper lubrication, avoid overloading, ensure correct installation alignment, and perform regular inspections to detect wear early.
What causes uneven rotation or increased torque?
This may result from improper installation or misalignment of the mounting surface. Ensure the housing and shaft have accurate flatness and concentricity before tightening the screws.
What are the common mistakes during installation?
Applying force directly to the rolling elements, over-tightening mounting bolts, or mixing incompatible lubricants are frequent errors. Always press-fit by the ring being mounted and use compatible grease only.
