RE25040 Crossed Roller Bearing - FAQ
What accuracy levels are available, and how should engineers select them?
+
-
RE25040 crossed roller bearings are available in standard and high-precision grades. The appropriate accuracy level depends on positioning requirements, rotational accuracy, operating speed, and equipment performance. High-precision grades are typically recommended for robotics, rotary tables, medical equipment, and other precision motion systems.
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.
