YDTech® manufacture of precision super short needle roller pins! Supplier of short cylindrical roller, wedge rollers in china.

we manufacture super miniature diameter super needle rollers, the minimum diameter 0.5mm, and we supply super short cylindrical rollers, such as 0.5*0.8mm.1.0*1.0mm, 1.5*1.5mm, 2.0*2.0mm, 3.0*3.0mm, 3.5*3.5mm, 4.0*4.0mm

These surface shapes are very critical to the operation of the components. However these shapes are on the order of typical surface texture features. So how do we assess the “shape” in the midst of the “texture”? Furthermore, if we have some nominal shape that we are shooting for, how do we assess the errors relative to it?

we are manufactured precision rollers parts. including cylindrical rollers,spherical rollers, 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.
