Characteristic for miniature linear motion

1. widened mini linear slide design improve largely torque load capacity. 2. adopts Gothic four points contact design, can bear high load from all directions, high rigidity and high precision. 3. has balls retainer design, also can be interchangeable.

we take model 12 for example

Dimensions

Complete dimensions for all mini linear slide rails size see below table or download our catalog: PMGW7, PMGW9, PMGW12

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 :
