Product Details

If you are going to import lb bearing in stock or you want to check the price with one China lb bearing manufacturer, supplier and factory, please feel free to contact Weinuo Machinery.

The linear ball bearing consists of a polymeric cage with raceway segments made of hardened steel to guide the ball sets within the complete system. 

1. LB Type : 

LMB-D.jpg

Standard type:  This type composed of an outer ring, steel balls and a cage is a cylindrical bearing for the most universal applications, which ensures precise and smooth infinite linear motion due to its outer ring of high rigidity.

OP type:  This type is composed of an outer ring,steel balls and a cage. And the outer ring and the cage are of arc sectional shape, from which one row of balls (equivalent to 50° to 60° degree spacing) is removed. Thus, the arc cross-sectional ring and cage with 50° to 60° degree opening allows the bearing assy to pass through a shaft support truss or a shaft support stand on midway of the shaft stroke. This type also ensures precise and smooth infinite linear motion, similarly to other types. The bearing radial clearance can be also adjusted.

AJ type: This type is composed of an outer ring, steel balls and a cage. And both of the outer ring and the cage have an axial slit, as illustrated, so as to enable to shrink the inscribed circle diameter of the cage by pressing the outer ring in radial direction from the housing and to thereby

adjust radial clearance from shaft. Thus, this type also ensures precise and smooth infinite linear motion.

Seal: Double-side seal. 

Grease: Prefilled. 

2. CAGE: polyamide resin cage.  

3. INTERNAL CLERANCE: Standard clearance or customized clearance.
