The RSTO40 RICH is a heavy-duty yoke-type track roller without inner ring, designed for applications where the shaft serves as the raceway. With dimensions of 50 mm bore, 80 mm outer diameter, and 19.8 mm width, it is ideal for cam mechanisms, guide tracks, and linear motion systems requiring high load capacity and compact design.
Its cylindrical outer ring ensures stable contact on flat surfaces, promoting smooth rolling and even load distribution. The absence of an inner ring allows direct mounting onto hardened shafts, increasing rigidity and simplifying assembly. The steel cage provides reliable roller guidance and mechanical stability under dynamic conditions.
The open (unsealed) configuration is suitable for environments with external lubrication, offering low friction and long service life. Manufactured in China, the RSTO40 RICH is a cost-effective and dependable alternative to INA components.
Transparency Note: This bearing is produced under the RICH brand. The code RSTO40 is used solely for compatibility identification and does not imply any affiliation with INA or other manufacturers. The product is clearly marked with its actual brand and country of origin.
