The INA KP2N-20 support roller is a guidance component built to carry radial loads in rolling motion along tracks or profiles. Its stud mounts into the housing while the outer surface runs directly on the track, which keeps the surrounding design simple and cuts down on the number of parts. You will find it in cam systems, linear guides and drive mechanisms that call for precision and rigidity. MR Industrial Accessories supplies it within its INA bearing line.

Reading the code helps you confirm you are ordering the right item. KP marks the support roller family, 2 is the dimensional series, N is a construction variant tied to a particular stud or mounting style, and 20 refers to the track diameter or roller size. The hyphen in KP2N-20 separates the base code from the size. Always match the complete part number shown on the drawing or on the part you are replacing.

Typical applications include automation, machine tools, packaging equipment and conveyor lines. These rollers also show up in chain guides, cam systems on textile machines, presses and positioning devices. Their job is to carry the load while allowing relative movement at low friction, so they are chosen when compact, precise rolling is needed. Continuous-motion equipment with a raceway built into the machine is another common setting.

When selecting a support roller, look at the track diameter, the width of the rolling surface and how the stud mounts. Sealing matters if dust, chips or coolant are present, since a sealed roller keeps lubricant contamination out. Lubrication may be permanent or relubricable depending on the design. During mounting, check that the stud aligns with the track to avoid side loads and premature wear. If the roller runs on a cam, verify the profile and eccentricity.

Support rollers are identified by their designation and dimensions. Other brands may offer products with similar functions, but the codes are not directly interchangeable: diameter, width, stud type and load capacity all have to be compared. For a replacement, start from the original part number and confirm the measurements with an instrument. MR Industrial Accessories can help you locate the equivalent reference within its bearing line.
