Typical Applications
RB11012 Crossed Roller Bearing – FAQ
Can the RB11012 be mounted directly without adjustment?
+
-
It's recommended to perform a flatness check on the mounting surface before installation. Minor misalignment can affect bearing accuracy and lifespan. Always use uniform torque when tightening bolts.
Can RB11012 be customized for special applications?
+
-
Yes. Custom options include special coatings, non-magnetic materials, integrated seals, or modified preload settings to match specific mechanical structures.
Is the RB11012 interchangeable with other RB-series bearings?
+
-
The dimensions follow standard RB specifications, but preload, accuracy class, and material may vary. Always verify specifications before substitution.
How long does it take to ship the RB11012 after ordering?
+
-
Standard models are usually shipped within 3–5 working days. Customized accuracy or preload options may require 10–15 days of lead time.
How are bearings inspected before shipment?
+
-
Every RB11012 undergoes dimensional inspection, rotation smoothness testing, clearance verification, and noise-level measurement to ensure full compliance with tolerance standards before dispatch.
