Application for Mini Linear Bearing

PMGW linear guides application include: semi-conductor machine, printing electric board IC assembly equipment, medical equipment, mechanical arm, precision measurements, official automation machine and other miniature linear guides.

Precision Level

miniature linear guide rail precision includes: Normal ( C ), High ( H ), Precision ( P )

Preload

miniature linear guide has Normal, Zero and Light preload, see below table:

Preload level	Mark	Preload	Precision
Normal	ZF	4~10 um	C
Zero	Z0	0	C-P
Light	Z1	0.02C	C-P

Dust Seals

For normal miniature linear bearings, we install oil scrappers on both ends of block to avoid the dust or particles into the inside of block to affect the service life time and precision. The dust seals are installed under the block to avoid the dust or particles into the block from bottom, if clients want to choose the dust seals, can add +U after the miniature guide rails model.

See below table for installation space :
