Unlike rolling bearings, which rely on rotating balls to transmit load,
slide bearings are stationary components that conduct smooth sliding motions. They are used in a wide variety of industrial applications. Their lubricated nature makes them ideal for handling large weights. They are also useful in high-speed applications and in extreme temperatures. They can be manufactured in a variety of shapes and sizes.
Most commonly, slide bearings are constructed of high performance polymers and graphite. However, there are other materials, such as bronze and steel. PTFE is another common material. The material is typically bonded to a thin metal shell. The material is a highly slippery substance, which helps minimize friction.
These types of bearings can support axial loads in both directions. The amount of load that they can handle depends on the type of load that they are designed to perform. In general, they are capable of carrying a maximum load of 21,000 pounds. They can withstand a minimum load of 7,355 pounds.
The material that is used for a slide bearing is important. The ideal material is one that can withstand abrasion and chemical washdown procedures. It should also provide a good balance of tensile strength, corrosion resistance, and durability.
The thickness of the bearing pad should be at least 2.5mm. This thickness is sufficient to allow for misalignment of the structure while maintaining the ideal reduction in cold flow. The bearing pad should also be thick enough to accommodate dirt embedment.
