Bearings with Plastic Wheel BPW-STR

Bearings with Plastic Wheel BPW-STR
ISUTAMI BPW-STR bearings with plastic wheel , also known as BPW-STR conveyor bearings with plastic. This series of bearings consists of a metal ball bearing and a bearing inner ring with a fixed shaft. The bearing steel balls contact the inner and outer rings and forms a separate ball bearing with the retainer. This is a single row ball bearing with a slightly convex plastic outer ring on the metal bearing.

Bearings with Plastic Wheel BPW-STR Features

ISUTAMI plastic bearing as a whole is a lubrication material, long service life, in use will not occur rust phenomenon and corrosion resistance, different from metal bearing easy to rust can not be used in chemical liquid.ISUTAMI plastic bearing is light weight, more suitable for modern lightweight design trend.The manufacturing cost of plastic bearing is lower than that of metal;Generally used is the injection molding processing is suitable for mass production, plastic bearings in operation without any noise, has a certain vibration absorption function, under special conditions, plastic sliding bearings suitable for high and low temperature work -200 ~ +250 degrees.

The inner ring of BPW-STR series bearing with plastic is a cylinder, having an inner diameter (d) of 0.31''-0.43''. Cooperating with the inner ring is a short circular shaft with a flange , which is directly fixed in the inner metal ring. The diameter (D) of the outer ring is 1''-1.25’’, and the length of the outer ring is 0.31''-0.47'', it is same as the length (B) of the inner ring. The length of the entire bearing (E, including the connecting shaft) is 1''.

BPW-STR series bearings with plastic wheel adopt standard ball bearing structure, which can realize light weight and free rotation. The main body of the bearing is an independent ball bearing. The structure is much more stable than the stamping assembly structure, and the noise is smaller, moreover, the operation of the corresponding accessories is smoother. The bearing in this structure has a stronger bearing capacity and is suitable for use in a tough mechanical environment. It may be installed on the holder of the trolley, or it can be used as a sliding part for moving doors as well as windows, and at the joint of other furniture.
