A support roller from the INA RSTO series handles radial forces while its outer race works directly as a rolling surface. This makes it a practical choice for cam drives, linear motion guides and conveyor lines where friction reduction and load absorption matter. The design supports continuous, accurate movement in industrial equipment.

The RSTO code combines a family prefix with a size number. RSTO identifies the support roller type, and the digits that follow give the outer diameter or a key dimension. For instance, RSTO10, RSTO12 and RSTO15 are distinct sizes in the same line. Reading the code this way speeds up matching a roller to the space available and the load it must carry.

These rollers appear in machine tool guideways, belt and roller conveyors, packaging machines and cam mechanisms for automation. Food processing, textile and automotive plants also use them where movement must stay smooth and dependable under changing loads.

Choosing the correct roller means checking the radial load, the speed of rotation and the operating environment. The mounting must be aligned accurately to prevent early wear. Lubrication and seals that keep out dust and moisture help the component last. In tough conditions, confirm the internal clearance and cage style.

Support rollers in the RSTO series are offered under various brands with similar part numbers. For a replacement, compare the critical dimensions and load ratings rather than relying on the code alone. MR Industrial Accessories supplies the INA brand within its bearing range and can help you find interchangeable references.
