Wholesale OEM PMGN Precise Mute Linear Sliding Guide Rails
PMGW Wide Linear Rail
1. convenient installation
2. complete specifications
3. adequate supply
1. Rolling system
block, rail, end cap, steel balls, retainer
2. Lubrication system
PMGN15 has grease nipple, but PMGN5, 7, 9,12 need to be lubricated by the hole at the side of the end cap
3. Dust proof system
scraper, end seal, bottom seal
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.

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 :
