The INA LR series needle roller bushing is a thin-walled radial bearing that combines a drawn steel outer ring with a needle roller cage. It handles radial loads in compact assemblies where a ball or roller bearing will not fit. Machine tools, transmission equipment and precision mechanisms rely on it for high load capacity in a minimal diameter.

Reading the LR series code is straightforward: the letters mark the needle roller bushing family, and the number that follows is the shaft diameter the bushing is intended for. LR20, for instance, fits a 20 mm shaft. Standard catalogue part numbers in this series carry no extra suffixes, so the complete designation is just the letters and number. For a sealed or otherwise modified version, confirm the exact part number before ordering.

These bushings are common in machine tool beds, milling machine heads, camshafts, pumps, compressors and general transmission mechanisms. Lifting and conveying equipment also uses them where radial space is limited and a reduced outer diameter with high load capacity is required. They often replace friction bushings and improve motion efficiency.

Selection calls for checking shaft diameter, outer diameter and overall width, along with the radial load the bushing must carry. The shaft surface needs suitable hardness and roughness, and the housing must ensure concentricity. Grease or oil lubrication is possible, and many installations run with permanent lubrication. Keeping shaft and housing aligned prevents lateral stresses that shorten service life.

INA needle roller bushings interchange with other European brands that follow the same dimensional nomenclature, such as SKF, FAG or NTN, provided shaft, outer and width dimensions match. Part numbers alone are not enough: tolerances and needle type should be compared. MR Industrial Accessories can help you find the right replacement based on your equipment's actual dimensions.

If you already have the bushing part number, send it via WhatsApp or email and the team will reply promptly with a quote. If the part number is unknown, share the shaft and housing dimensions and we can help identify the part. MR Industrial Accessories supplies the INA line.
