Plastic Bearings

With a range of plastic bearings in popular metric and imperial sizes available from stock, and a range of custom design options available, find out more about plastic bearings today.

Share This Page

With unparalleled versatility and the ability to integrate into the most complex systems, plastic bearings are lightweight, lubrication and maintenance free, nonmagnetic, nonconductive, and incredibly corrosion resistant. They are commonly used in offshore, medical, and semiconductor applications, and using specialist injection mould tooling, UNASIS can deliver a range of features that wold simply not be possible using conventional manufacturing methods.

Chemical Compatibility

Ball Materials

Common Materials

One of the biggest benefits to plastic bearings is their resistance to harsh chemicals in extreme environments. With decades of experience and a library of information supporting these applications, our engineers can advise on the best materials for your chemical solution so get in touch today.

With a multitude of different ball material options including Acetal, Borosilicate Glass, and 316 Stainless Steel, our bearings can be custom configured to any style ball given the application requirement. Other popular material options include alumina, polypropylene, silicon nitride, ruby, and Torlon®.

  • Acetal (POM, Celcon®)
  • PEEK
  • PVDF (Kynar®, Solef®)
  • PTFE

Advantages

Corrosion Resistant

Due to their corrosion resistance, plastic bearings can reliably function in the most extreme environments. From salt water to particularly extreme chemicals, plastic bearings can present the best solution.

Nonconductive

Races and balls made from non-metallic materials such as plastic eliminate electron flow, which could be a necessary benefit to your mechanical system, particularly if system conductivity is a concern.

Shock Absorption

Plastic bearings offer higher levels of shock absorption than their metal or ceramic counterparts due to their higher elasticity. This reduces brinelling-caused bearing failure.

Free Spinning

The significant weight savings offered by plastic bearings reduce the centrifugal forces on the bearing race surface, allowing them to run freer with less inertia.

Custom Design with Complex Features

Creating plastic bearings with injection moulding allows for otherwise impossible features to be easily integrated into the design. This expands the designer’s imagination and helps to create complex and innovative solutions.

Product Integration

Plastic bearings have a highly customisable design that can broaden the possibilities for product integrations. This both minimizes the assembly time and reduced the number of parts needed in the system, making the overall product more affordable.

Lightweight

Plastic bearings are up to 5 times lighter than their steel counterparts which has a myriad of benefits.

Noise Reduction

The inherent mechanical properties of most plastics significantly reduce the noise made while running, dampening the system overall and minimising harmful harmonics.

Lubrication Free

Eliminating metal-to-metal contact also eliminates micro-welding adhesion. This means that plastic bearings can run without lubrication, making them maintenance free and a great choice for clean applications.

Hygienic

Lubrication is unnecessary for plastic bearings, making them a great solution for pharmaceutical and medical applications. Their corrosion-resistant properties also mean they can be regularly washed down or otherwise sterilised using standard methods, like Gamma or autoclave.
