Sliding bearing; bearing operating under sliding conflict. Sliding bearing works smoothly, firmly, without noise. Under liquid smooth conditions; sliding surface is separated by smooth oil without direct touch; can also greatly reduce conflict loss And the appearance of wear; the oil film also has a certain vibration absorption ability. However, the resistance of the starting conflict is relatively large. Some of the shafts are supported by the bearings, which are called journals; the parts that are matched with the journals are called bearing bushes. In order to improve the conflicting properties of the bearing shells, The anti-friction material layer cast on the inner and outer surfaces is called the bearing lining. The data of the bearing bush and the bearing lining are collectively referred to as the sliding bearing data. The commonly used sliding bearing materials are bearing alloy (also known as babbitt or white alloy), wear-resistant cast iron, copper. Base and aluminum-based alloys, powder metallurgy materials, plastics, rubber, hardwood and carbon-graphite; polytetrafluoroethylene (Teflon, PTFE), modified polyoxymethylene (POM), etc.
Sliding bearings are usually used under low speed and heavy load conditions; or they are difficult to protect and fill smooth oil.

Stainless Steel Bushes Flange Bushing are cylindrical objects with one end turned down to produce a wider edge. On the outside, the turned down portion of the cylindrical part, often called the flange, produces 2 diameters (OD) & two lengths. Meanwhile the entire part has one inside diameter (ID), usually a clear hole drilled through but threaded in some cases. The tube portion below the flange is called the shank, and is often inserted into a chassis to provide support for a rotating shaft, with the flange serving to prevent the bushing from going through the hole. It can also be used to provide spacing, with the shank serving to center a shaft or fastener.

Bushings can be made of almost any material, but are most commonly made of stainless steel. Nylon and Polyurethane are common materials for bushings as well. Our manufacturing processes can hold tighter tolerances than the industry standard and allow for the fastest turnaround of parts as needed. Part lengths can be modified to suit any customer requirement.
