THK - RB 15030 | Cross Roller Bearing | 150 × 230 × 30 mm

Details

THK RB 15030 is a cross roller bearing with inner diameter 150 mm, outer diameter 230 mm and width 30 mm. Additional specifications include bore type CYLINDRICAL, seal YES, cage STANDARD and lubrication STANDARD.

The THK RB series is a high-precision, thin-section Cross-Roller Ring designed for applications where high rotational accuracy of the inner ring is critical. It features a separable outer ring and an integrated inner ring, allowing for a compact design that maintains high rigidity even under complex loading conditions. Cylindrical rollers are arranged perpendicularly in a 90° V-groove. This "cross" orientation enables a single bearing to absorb radial, axial, and moment loads simultaneously. Unlike standard sheet metal cages, the THK RB series uses spacer retainers between rollers to prevent skewing and friction-induced torque spikes, ensuring stable rotation even under preload. Material : The rings and rollers are typically crafted from high-carbon chromium bearing steel (GCr15), providing the necessary hardness and fatigue resistance. Features are : Enhanced Rigidity, Space Saving, High Positioning Accuracy, Temperature Resilience, Lubrication System, Cost-Effective Design. Applications : Robotics & Automation, Medical & Precision Equipment, Aerospace and Defence, Wind Turbine Monitoring, Semiconductor Manufacturing.
