The INA STO series covers cylindrical support rollers built to carry radial loads while allowing guided movement or translation inside industrial mechanisms. Typical uses include cam drives, linear guidance and conveyor setups, where a durable contact surface and low friction are needed. The compact envelope suits assemblies with limited mounting space that still require precise motion.

Reading the code is straightforward: the letters STO come first, then a number that equals the roller outer diameter in millimeters. STO10 is a 10 mm outer diameter, STO20 is 20 mm and STO35 is 35 mm. That makes sizing quick once you know the space and the load the position has to handle. Any suffix added to the designation points to a design variant, such as a sealing arrangement or a crowned running surface, while the basic STO code stays limited to the letters plus the number.

These rollers show up in machine tools, packaging lines, material handling systems, presses and automotive work, as well as in food and pharmaceutical operations that call for smooth running. Their radial load capability and resistance to contamination suit tougher environments.

Selection comes down to the radial load at the position, the rotation speed and the surrounding conditions. Alignment has to be precise so the roller is not fighting extra stress or wearing early. Grease or oil lubrication, applied as specified, helps the roller reach its service life. Where dust or moisture is present, a sealed variant is the better choice. Check that the shaft diameter and the roller outer diameter match the mechanism design, then install carefully and keep to a regular maintenance interval.

Equivalent rollers from other sources may carry different designations but keep standardized dimensions, which supports interchangeability. For a replacement, compare the critical dimensions: outer diameter, bore diameter and overall width. Internal design can differ between suppliers, so confirm dimensional and load compatibility before fitting a substitute.
