linear bearings sbr20 chrome steel SBR20 bearing

linear bearings sbr20 chrome steel SBR20 bearinginclude:

Length: 700mm
The shaft is case hardened. If you use normal steel shafts, the bearings will cut them up in no time. So make sure what you buy is case hardened!
Aluminum support rail with pre-drilled holes for ease of mounting
Perfect for your DIY CNC routers, mills, lathes
For 20mm slotted bearings
Suits X, Y, Z axis
No more unwanted errors in your machining work!
All items located in Melbourne, so you will get it fast and packed well! Don't risk having it shipped from overseas!
These rails are also available in diameters of 16mm, 20mm, 25mm and 30mm
Brand new!
Please check out my other CNC items & we do provide combined shipping!

Linear Bearings

offer almost types of linear bearings (LM,LME,LMF,LMH,LMK,KH,etc)Size range is from ID6-60mm
2.Linear motion bearings have the characterized of smooth movement,low friction,high rigidity and long life span,economical and easy to maintain or replace

3.Applications:Widely used in the defense,precision machinery,medical instrument,chemical,printing,agriculture,robotic,automatic production line etc

4.our top mission is 100% quality control and 100% customer satisfied. we are responsible to assist our customer to be competitive and advantaged in the market

5.It is little that the sport ball bearing of straight line has friction mainly with the position in the reciprocating sport of straight line in mechanical equipment , sport flexibility and repair the advantage of changing convenience. It is used in the weaving mechanical weapons, medicine machinery and punctuality of printing machine extensively machine tool: The fields such as the automatic recorder and cutoff machine of electrical equipment.

Product Description
MATERIAL STRUCTURE

1) PTFE/Pb Composition, 0.01~0.03mm, anti-abrasion material, which will form a lubricating film during operation.

2) Bronze powder layer, 0.2~0.35mm, which further strengther the combination of the steel plate and PTFE layer and transfer the heat more quickly.

3) Low carbon steel, bear high load and transfer heat.

4) Copper/Tin plating layer, anti-corrosion.

APPLICATION CHARACTER

1) Working under oilless or minim oil state, maintenance free or just need a little maintenance.

2) Resist Abrasion, low coefficient of friction long operating life.

3) Operating in -195~+280

4) Good mending, low-noise, non-pollution

5) Thin wall, light, which can reduce the cubage of the machine.

6) Forming a transferred film during operation to protect shaft

7) Low demand to the shaft even no surface hardness treatment, which lower the cost of the mating components.

8) No absorption to water/oil, small coefficient of Thermal expansion, good thermal conductivity and size stability.

9) The back of the steel strip can be plated with various metal, anti-corrosion.

The products now are used in sliding components of different machinery, such as auto machinery, piston pump, gear pump, textile machine, auto-sides machine, injection machine, sports machine, office equipments etc.
