Key Features
- The RE20035 Crossed Roller Bearing is a slim-section, high-rigidity rotary bearing engineered for precision platforms where stability, repeatability, and compact installation are critical.
- Its integrated inner/outer ring structure provides a stable preload and ensures consistent accuracy under combined loads.
Reinforced Structural Rigidity
A wider cross-section enhances load distribution and reduces micro-deflection during high-precision rotation.
Stable Preload
Design
Factory-set preload maintains uniform torque and minimizes axial play without additional adjustment.
High Accuracy for Compact Systems
Designed for applications with limited space while still delivering stable rotational accuracy.
Improved Thermal Stability
Optimized internal geometry reduces heat accumulation, maintaining consistent performance during continuous operation.

RE20035 Crossed Roller Bearing – FAQ
How should the RE20035 be mounted to avoid accuracy loss?
Use a flat, rigid mounting surface and tighten bolts in a star pattern. Uneven torque can distort the rings and reduce rotational accuracy.
Can the RE20035 be customized?
Yes. Options include special grease, tighter accuracy grades, stainless steel, integrated seals, or modified chamfers to suit unique equipment designs.
How does moment load influence the wear pattern?
High moment loads push rollers toward one side of the raceway, creating localized stress. If sustained, this leads to point contact wear and premature fatigue. The RE20035's wider cross-section helps distribute moment loads more evenly, but correct load matching is still necessary.
What vibration spectrum characteristics indicate bearing issues?
Higher-frequency peaks often correlate with roller/raceway contact anomalies, while lower-frequency oscillations can stem from uneven preload or mounting distortions. If vibration intensity increases over time, an inspection of lubrication and torque settings is recommended.
