RE13015 Crossed Roller Bearing – FAQ
Why does the RE13015 produce higher torque after installation?
This is usually caused by uneven tightening of the mounting bolts or slight deformation of the housing. Loosen the bolts in a diagonal pattern, re-center the bearing, and retighten using a controlled torque value.
What causes uneven rotation or small vibration at low speed?
This usually indicates excessive preload or misalignment of the mounting surfaces. Check that the mounting faces are flat and parallel, and verify that the bearing was not compressed during assembly.
How do I avoid contamination during assembly?
Install in a clean, dust-free area, avoid touching the raceway with bare hands, and ensure tools are clean. Even fine particles can increase wear and reduce bearing life.
Can I run the RE13015 without seals?
It's possible, but not recommended for environments with dust or coolant mist. Sealed versions provide better protection and longer service life with minimal torque increase.
How can I detect early-stage raceway wear?
Common early indicators include a faint clicking sound, slight rotational unevenness, or a small but consistent rise in operating torque. An increase in metal particles during re-greasing is another clear warning sign.
How do I verify the housing stiffness is adequate?
If torque changes noticeably when the bolts are tightened, the housing may be deforming. Properly designed housings should maintain stable torque through the entire tightening cycle.
