The RSTO12 RICH is a compact yoke-type track roller without inner ring, designed for applications where the shaft serves as the raceway. With dimensions of 16 mm bore, 32 mm outer diameter, and 11.8 mm width, it is ideal for cam followers, guide tracks, and linear motion systems requiring smooth tracking and high load capacity.
Its crowned outer ring helps reduce edge stress and compensates for minor misalignments, ensuring stable motion across curved or uneven surfaces. The steel cage provides reliable roller guidance and durability under dynamic loads. The open (unsealed) design allows for external lubrication, making it suitable for clean or controlled environments.
Transparency Note: This bearing is manufactured under the RICH brand. The code RSTO12 is used solely for compatibility identification and does not imply any affiliation with other brands. The product is clearly marked with its actual brand and country of origin.
