Overview
The Thomson RW24V is a RoundWay linear roller bearing designed for high-load, heavy-duty applications. This unit features a 1.5-inch shaft diameter and self-aligning geometry with a dual V mounting block configuration. The RW24V includes two hardened steel recirculating rollers mounted in a rigid malleable iron block, making it suitable for contaminated or demanding industrial environments where conventional ball bushings cannot perform.
Key Features
- Self-Aligning Design: Compensates for slight misalignment and variation in linear shafting
- High Load Capacity: Recirculating steel rollers deliver up to 20× the load rating of linear ball bushings
- Dual V Mount Block: Provides stable, dual-rail mounting with eccentric trunnion pin adjustment
- Contamination-Resistant: Chain-linked roller design operates reliably in dusty and debris-laden environments
- High-Speed Capability: Capable of speeds up to 100 ft/s (30.5 m/s)

- Mounting Block Height: 3.38 inches
- Bolt Center Distance (Across Shaft): 6.0 inches
- Mounting Hole Diameter: 0.38 inches
- Number of Rollers: 2 bearings (chain-linked)
- Material: Steel rollers; malleable iron mounting block
- Mount Type: Dual V; self-aligning with eccentric trunnion pin
- Weight: 5.31 kg (11.7 lbs)
Typical Applications
- Heavy machinery positioning systems and transfer equipment
- Semiconductor manufacturing and clean-room motion systems
- Packaging and material handling conveyors
- Press and stamping equipment carriage drives
- Contaminated or outdoor industrial environments where sealed ball bushings are inadequate
