INA NA series support rollers are cylindrical roller bearings built with a compact, sealed configuration to handle high radial loads where mounting space is tight. They serve as cam followers or support rollers in cam drives, linear guides, conveyors and reciprocating mechanisms. The 2RSR sealing helps keep dust, chips and moderate humidity out while holding lubricant in, which supports longer assembly life and less maintenance.

Reading the NA series code: NA identifies a support roller of the NA series with standard dimensions; the following number sets the size and main dimensions; the 2RSR suffix means elastomer seals are fitted on both sides. That combination lets you confirm size and sealing type at a glance.

These rollers appear in machine tools, packaging lines, conveyor belts, engine cam systems, presses, cranes and agricultural equipment, as well as in food, automotive and metallurgical operations that need precise, load-resistant radial motion. Their compact envelope suits cramped spaces and makes them a practical replacement for bushings or conventional bearings at pivot points.

When selecting a roller, consider the radial load, rotational speed, lubrication method and operating environment. 2RSR sealing fits dusty or humid conditions; for submerged or high-temperature service, review other sealing options. During mounting, check shaft and housing alignment and confirm the roller turns freely. The sealed design comes with lifetime lubrication, though severe duty may call for periodic relubrication.

INA NA series support rollers interchange with equivalent products from other brands that follow the same dimension standard.
