RE25040 Crossed Roller Bearing - FAQ
What accuracy levels are available, and how should engineers select them?
+
-
The RE60040 is typically available in P5 and P4 accuracy grades. P5 is sufficient for most industrial automation and heavy positioning systems, while P4 is recommended for high-precision rotary tables or inspection equipment where runout and rotational consistency are critical.
What preload options should be considered during selection?
+
-
Preload selection depends on system stiffness requirements and operating conditions. Light preload reduces friction and is suitable for higher-speed applications, while medium preload improves rigidity for precision positioning systems. Engineers should balance stiffness, torque, and service life when specifying preload.
What should I check before installation?
+
-
Verify shaft and housing tolerances, clean all mounting surfaces, and ensure no burrs or distortions are present. Proper preparation significantly affects bearing performance.
What happens if the mounting bolts are over-tightened?
+
-
Over-tightening can distort the bearing rings, leading to increased torque, uneven rotation, or reduced accuracy. Always follow recommended torque values.
How often should maintenance be performed?
+
-
Maintenance intervals depend on operating conditions such as load, speed, and environment. In general, periodic lubrication and inspection every few months is recommended for stable operation.
