Turning Bearing BW-A Features

The BW-A series has two structures, A type and R type. The inner ring of the A-type bearing is a cylinder, the inner diameter (d) is 0.25'' and the inner ring height (E) is 0.38''. The outer side of the outer ring of the bearing is a U-shaped groove, also called Gothic groove, and the inner side of the outer ring also has a closed groove for placing the bearing steel balls. The diameter (D) of the outer ring is 1.26''-1.5'', and the height (B) of the outer ring is 0.32''.

The inside of the inner ring of the R-type bearing is also a cylinder, with a groove on the outside for mounting the steel ball. The inner ring inner diameter (d) is 0.25'' and the height (E) is 0.38''. The outer side of the outer ring of the bearing is a U-shaped groove,too. And the inner side of the outer ring also has a closed groove for placing the bearing steel balls. The diameter (D) of the outer ring is 1.26''-1.5'', and the height (B) of the outer ring is 0.32''.

Due to the double fastening of the inner and outer rings, the R model turning bearing has a stronger capacity and higher stability in the thrust direction.

BW-A turning ball bearings feature standard ball bearing construction for lightweight, free turning to meet the demands of today’s low incline conveyors.
If BW-A series bearing is made of stainless steel, it can be washed down, becoming maintenance free and requiring no lubricant. They can be used in standard industrial tube and pipe sizes for use in conveyor systems.
