Loose Needle Rollers

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.

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.

Production Machines For Roller Elements

Instrument name Instrumentation Type Use
Metallurgical Microscope Detection of roller Needle heat treatment microstructure testing equipment accuracy measurement
Centerless grinding roller bearings, needle roller machines production equipment diameter grinding
Sorting machines detection of roller, needle roller cylindrical separation sorting equipment product separation
Hardness Testing Machines testing roller bearings, needle hardness of the heat treatment instrumentation hardness

Some specialist bearings have convex barrel shapes or concave profiles depending on the application type and conditions. pure cylindrical roller bearings cannot support any load in an axial direction. if axial support is required a separate bearing arrangement will be required.
