Product Description

Product Description

Needle bearing
Needle bearing is a cylindrical roller bearing, relative to its diameter, the roller is both thin and long this roller called needle although has a smaller section, bearing still has a higher load bearing capacity, needle bearing is equipped with thin and long roller (roller diameter D 5mm,L/D 2.5,L is the length of roller), so the radial structure is compact, and its inner diameter size and load capacity are the same as other types of bearings, while the outer diameter is the smallest, especially suitable for the radial installation size of the support structure is limited .
Metric and inch needle bearings have various structural types, mainly including open stamping needle roller bearings, closed stamping needle roller bearings, needle roller bearings with inner ring and needle roller bearings without inner ring/without inner ring Cage needle roller bearings, caged and cageless needle roller bearings. Widely used in automobiles, motorcycles, mopeds, power tools, textiles, agricultural machinery, printing machinery, construction machinery, automatic instruments and other fields.
