ball bearings
Standard products are available in both deep groove and angular contact designs.
Standard bearings are typically manufactured from common materials such as 100cr6, Gcr15 or stainless steel alloys, and utilise steel balls. A variety of cage types and lubricants are available and generally selected to compliment the operating environment.
Depending on the application and performance requirements, special materials can be used. These include corrosion-resistant high nitrogen steels, ceramic balls, high performance plastic cages and solid lubrication.
An extensive range of bearing types are available, including:
- deep groove ball bearings
- angular contact ball bearings
- thin section bearings/flex bearings
- four-point bearings
- double row ball bearings
- double row angular contact ball bearings
roller bearings
BTC's roller bearings comprise of steel inner and outer rings with cylindrical rolling elements. These bearings can also have cages incorporated into the design, depending on the application requirements.
BTC roller bearing products are optimised to have high radial load capacity, high speed capability and low friction. We supply a number of different designs, sizes and configurations in this range, including multiple roller rows, cage material, full complement and flanged designs.
Further information can be requested from our expert engineering department.
needle bearings
Needle bearings are characterised as bearings which incorporate small diameter/long length rolling elements and are typically in a wide range of applications and operating conditions.
They are ideal in applications where a very high load carrying capacity, a compact design is required or where axial displacement must be accommodated. Various needle bearing types are available from BTC Engineering, including flanged variants, outer ring only, or multiple row configurations.
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 for 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.
special bearings
For particularly demanding applications, BTC can develop tailored solutions for our customers. Customised solutions may include the use of special lubricants, sealing solutions and heat treatments. Additionally, hybrid bearings which comprise of ceramic balls with stainless steel rings and rolling element, as well as ring-guided cages are possible, depending on the customer’s requirements.
