Rectangle wheel linear rail high precision mute slide SGR20N 47mm width with lock slider SGB20N-3 -4-5

SG Type

   Linear bearings feature an extruded aluminum, lightweight rail and block. The blocks are available with 3, 4 or 5 double angular contact rollers which are factory lubricated and sealed for the life of the bearing.

   SG bearing blocks also feature a unique eccentric adjustment nut which allows for easy adjustment of the running clearance ( preload ) between the double angular rollers and shafting.

   The rail model number have SGR10/SGR15N/SGR15/SGR20N/SGR20/SGR25/SGR35

SGR20N linear guide rail

Material: Chrome steel shaft, and aluminum tray

Width: 47mm

Length: Requirments
Roller bearing block : 3 4 or 5 wheels

Features:

1. Cost saving: no lubrication, reducing oil costs.

2. Clean and environmental protection: No oil spills and oil spills during forced lubrication, suitable for use in environments with high cleanliness requirements, with environmental protection concept.

3. Flexible installation: The slider can be normally lubricated without any installation direction limitation.

Easy to assemble and disassemble: The design of the cassette fuel tank can be easily replaced on the machine to further extend the life.

4. Easy maintenance and long-term use: For normal users, almost no maintenance work is required during the normal life.

5. Special environment use: Such as dust environment, exposure to bad weather environment and water environment, due to the design of the double-axis and guide wheel, the double-axis guide rail itself has dust-proof characteristics, plus the dust on both sides of the slider Oil-sealed felt with double dustproof effect. It has the characteristics of anti-corrosion and anti-rust.

6. Adjustable guide wheel preload: Under different loads, the gap between the guide wheel and the guide rail is “zero”by adjusting the preload;

7. Parallel bearing guide wheel improves the precision by ±0.02mm, and the parallel precision within 0-6 meters does not produce obvious error; it can be used in high dust occasions, and the slider has low noise when running at high speed.

8. Eccentric nut design: easy to adjust, should be adjusted to the most suitable clearance for different loads;

9. Anti-loose design: eccentric nut type, the fixing nut of the bearing guide wheel is designed with anti-loose function.

10. High wear resistance: The steel shaft is specially hardened and has high abrasion resistance;

11. Unique design: The product design is sturdy (a combination of aluminum profile and bearing steel), can be used as a bracket or bottom plate, no need to grind the base surface to install the guide rail; the size of the guide hole and the slider mounting hole can be processed according to customer requirements.
