RE45025 Crossed Roller Bearing - FAQ
1. Can the RE45025 be customized for specific applications?
Yes. Custom options include cage materials (resin, brass, or steel), precision grades (P5–P2), and preloading levels to match your equipment's accuracy and torque requirements.
Under normal operation, lubrication should be checked every 3–6 months. In high-speed or continuous-use environments, shorter intervals are recommended to maintain smooth rotation.
If you notice increased vibration, unusual noise, or rising operating temperature, these may indicate improper lubrication or contamination. Stopping the machine immediately and rechecking lubrication and mounting alignment is recommended.
Yes. For vacuum or semiconductor applications, the bearing can be supplied without standard grease and filled with low outgassing or dry-film lubrication, suitable for clean, contamination-free environments.
Install in a clean, dust-free environment with proper alignment and torque balance. Use uniform tightening on the outer ring to prevent distortion, and avoid hammering or applying direct force to the bearing during assembly.
