Bearing

Widi is ball bearings manufacturer and supplier. A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. Ball bearings consist of a series of round balls in a casing, within an inner and outer ring capable of supporting both radial and axial (thrust) loads. Ball bearings come in both single and double row configurations, in both metric and inch sizes, and can be found in a large range of applications from door hinges to roller skates.

Widi is roller bearings manufacturer and supplier. Roller bearings — also known as rolling-element bearings — are similar to ball bearings in that they are designed to carry a load while minimizing friction. However, roller bearings transmit loads using cylinder rolling elements, rather than balls, to maintain the separation between moving parts of the bearing. These bearing systems use the decrease in rolling resistance as a means of increasing the efficiency of moving an object. Roller bearings typically fall within three categories: cylindrical, tapered, and needle.

Widi is mounted bearing units manufacturer and supplier. Mounted bearings, sometimes called bearing units or bearing blocks, have a bearing installed in a housing to ease installation and provide additional support for the bearing. Mounted bearing units are available with plain, ball and roller bearings. Mounted bearing units are available off-the-shelf . Mounted bearings are available in inch and metric sizes ranging from ½” to 16”.
