The INA NA-RSR-XL is a radial needle roller bearing that combines an inner ring with contact seals on both sides. It handles high radial loads in tight spaces where other bearing types will not fit, and the sealed design keeps lubricant in and contaminants out. This makes it a practical choice for equipment that runs in dusty, damp or poorly lubricated conditions.

Reading the part number helps you specify the right bearing. NA means a needle roller bearing with an inner ring. The digits that follow, as in NA4900-RSR-XL or NA4905-RSR-XL, set the size and load capacity. RSR tells you the bearing has contact seals on both sides. XL marks the manufacturer's optimized version. The series runs from NA4900-RSR-XL through NA4907-RSR-XL, with different dimensions across the range.

These bearings are common in machine tools, transmission equipment, pumps, compressors, cranes and lifting systems. You will also find them in automotive gearboxes and engines, and in agricultural machinery. Their compact, sealed construction suits environments where dust, moisture or limited lubrication would shorten the life of an open bearing, and where reliable operation with less maintenance matters.

When selecting an NA-RSR-XL bearing, check the radial load, speed, available space and operating conditions. Choose the RSR seal where contamination is a risk. If lower friction is the priority, consider open variants instead. During assembly, verify alignment and clean mating surfaces, lubricate to specification, and avoid impacts that could damage the seals. Make sure the cage and rollers are properly seated.

INA needle roller bearings can be interchanged with other brands that use the same dimensional nomenclature, such as SKF, FAG or NTN, but always confirm tolerances and seal type. The NA-RSR-XL series is distinguished by its sealing and optimized design.
