Bearings with Plastic Wheel BPW-R

Bearings with Plastic Wheel BPW-R
ISUTAMI BPW-R bearing with plastic wheel, also known as BPW-R conveyor ball bearing with plastic. This series of bearing is composed of an outer ring and an inner ring, steel bearing balls and a retainer, and the bearing balls connect the inner ring and the outer ring. This is a single row bearing with a Gothic groove or a Gothic embossment on the outer plastic ring, used as a transmission assembly part.

Bearings with Plastic Wheel BPW-R Features

PBW-R bearings with plastic wheel are generally available in two styles. The first type is that the outermost plastic outer ring is in the shape of a cam, and the inner metal ring is a cylindrical shape, which is suitable for the installation of a generally round metal shaft, and a sealing ring can be installed on both sides of the inner ring. The inner ring diameter (d) is 0.25''-0.5''. The metal outer ring of the bearing is tightly fitted to the outer plastic ring. The outer diameter (D) of the plastic outer ring is 0.75''-1.5'', and the length (B) of the outer ring is 0.75''-1.06''.

The outer ring structure of the second type bearing is the same as the outer ring structure of BW-A series of turning bearings. It is a concave semi-circular groove. The outer ring of this shape is generally used with the circular axis track. Except for the difference of the plastic outer ring, the rest of the data is the same as the first type of PBW-R bearing.

PBW-R bearing with plastic wheel is a stamped product, not assembled by independent ball bearings, the overall performance is not better than that with independent ball bearings. The outside of the inner metal ring and the inner surface of the metal outer ring have grooves for mounting the steel ball .

PBW-R with plastic transmission ball bearings adopt standard ball bearing structure, which can realize light weight and free rotation. Due to the use of a plastic outer ring, the overall weight of the series is much lighter than that of a stamping bearing or a turning bearing with the same specification. However, because of the poor strength of the plastic, it is generally installed in a small load-bearing device. It is usually installed on the bracket of the trolley, or it can be used as a sliding part for moving doors and windows, and at the joint of other furniture.
