needle rollers, tapered rollers, cuspidal ends

rolles, arc correction line rollers, logarithm

profile rollers etc. we will provide you quality needle roller with

competitive price and excellent service.

Precision needle rollers have multiple uses in a variety of applications. Needle rollers are

mainly used as bearing rolling elements to transmit torque and reduce friction. They can also

serve as precision shafts or as precision locating pins. Needle rollers with a controlled contour

profile are available to reduce end stresses. special end forms provide performance benefits

for specific kinds of applications.

One unique aspect of these critical profiles is

that certain areas of the profile must be

controlled to tighter tolerances.

Length of cylindrical rollersIGL=roller length gauge interval.

cylindrical rollers(regulation values,tolerance, grade, changes of length volume quantities,

length gauge value spacing, face runout value.
