Roller Linear Guide Rail

Roller lm guideways adopts roller as rolling elements instead of steel balls, can offer super high rigidity and very high load capacities, roller bearing slide rails are designed with 45 degree angle of contact which produces small elastic deformation during super high load, bears equal load in all directions and same super high rigidity. So PRG roller guideways can reach super high precision requirements and longer service life.

For PRGH-CA / PRGH-HA series linear roller slides, the definition of each code as follows:

size of 20 for example:

PRGH-CA / PRGH-HA block and rail type

Type	Model	Block Shape	Height (mm)		Rail Mounting from Top	Rail Length (mm)
Square block	PRGH-CAPRGH-HA		28 ↓ 48			100 ↓ 4000
Application
Automation systeml Heavy transportation equipment CNC processing machine Heavy cutting machines				CNC Grinding machinesl Injection molding machine Electric discharge machines Big gantry machines

Features

PYG^® brand linear motion details

linear bearing slide block

roller type linear guideway has high heavy load bearing, not easily to deformed,

easy installation

roller linear guide adopts roller arrangement, upgraded load capacity and easy installation.

roller bearing guide rails

square linear bearing adopts high quality bearing steel which is wear resistant, strong rigidity and heavy load bearing.

lm guideways selection

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.
