Loose Needle Rollers

Loose needle rollers main use is as rolling elements in bearings where they are particularly useful when space is limited and a high radial load is required. They are also useful as locating pins and mini shafts.

Needle Rollers for bearings is a roller with a cylindrical roller bearings, relative to its diameter, both the thin and long rollers. this is called needle roller.despite its smaller cross-section, still has a higher load bearing capacity, therefore, especially suitable for the radial space-constrained occasions.needle pins contour surface in the proximal surface of the slight contraction. needle and raceway contact line results can be amended to avoid damaging the edge of the stress.

Super Precision Needle Rollers are designed specifically to handle large radial loads in high-speed spindle applications that demand high running accuracy (runout) of bearing-spindle arrangements.
