Ball & Needle Thrust Bearings

BTC thrust bearings are designed to withstand a force in the same direction as the shaft, generally called an axial load, or thrust load. They are designed to only accommodate axial loads and therefore cannot be subjected to radial load. BTC thrust bearings are suited to low to medium speed use and are available as single or double direction designs.

Higher speed operation is better served by needle thrust bearings which have a guided needle roller cage. These bearings also accommodate high axial loads and provide high levels of stiffness and durability in a range of applications, including industrial machines, high pressure pumps and machine tools. 

Seals

BTC offers several sealing types, all designed to offer the maximum protection against dirt and contamination ingress and lubricant leakage and ensure the best possible performance of the bearings.

Seals are specified depending on the application, and come in a wide range of sizes and materials.

All BTC seals have been optimised to offer low friction and longer service life. They are particularly suited to applications which are contaminant heavy, such as the construction industry and food and beverage production.

Wavespring Washers & Shims

Wave spring washers from BTC Engineering are manufactured in a distinctive wave shape, which produces spring pressure under compression. They are generally used for axial preloading of roller bearings, in particular small and miniature bearings. Wave spring washers are suitable for a range bearing applications, including shafts and housings, heavy industry and gearboxes. They can be produced in a variety of diameters, thicknesses and materials, including corrosion resistant steel.

Shims are often used as a cost-effective way to balance axial manufacturing tolerances. They can also reduce wear on the faces between mating components by acting as a sacrificial component.
