Smooth Roller Type Linear Guide

Model PRGW55CA/PRGH55CA linear guide, is a type of roller lm guideways that uses rollers as the rolling elements. Rollers have a greater contact area than balls so that the roller bearing linear guide features higher load capacity and greater rigidity.  Compared to ball type linear guide, PRGW series block is excellent for heavy moment load applications due to low assembly height and large mounting surface.

Features of precision rail guides

1) Optimal design

The unique design if the circulation path allows the PRG series linear guideway to offer smoother linear motion

2) Super high rigidity

The PRG series is a type of linear guideway that uses rollers as the rolling elements. Rollers have a greater contact area than balls so that the roller guideway features higher load capacity and greater rigidity.

3) Super high load capacity

With the four rows of rollers arranged at a contact angle of 45-degrees, the PRG series linear guideway has equal load ratings in the radial, reverse radial and lateral directions. The PRG series has a higher load capacity in a smaller size than conventional, ball-type linear guideway.

Accuracy Class of precision rail guides

The accuracy of the PRG series can be classified into four classes: high (H), precision (P), super precision (SP) and ultra precision (UP). Customer may choose the class by referencing the accuracy requirements of the applied equipment.

Preload of precision rail guides

A preload can be applied to each guideway using oversized rollers. Generally, a linear motion guideway has negative clearance between the raceway and rollers to improve stiffness and maintain high precision. The PRG series linear guideway offers three standard preloads for various of applications and conditions:

Light preload (ZO), 0.02~0.04 C, Certain load direction, low impact, low precision required.

Medium preload(ZA), 0.07~0.09 C, high rigidity required, high precision required.

Heavy preload(ZB), 0.12~0.14 C, super high rigidity required, with vibration and impact.
