The Function Of A Centre Bearing In A Tailshaft

A centre bearing in a tailshaft is an important component that helps to reduce vibration and noise, as well as absorb shock loads. The centre bearing also assists in the transfer of rotational energy from the engine to the rear axle or differential. Without it, vehicles would experience excessive levels of stress on their driveshafts and other components.

The centre bearing is usually made of rubber or a synthetic material, and it is designed to provide support for the entire tailshaft assembly. The centre bearing consists of two pieces: the stationary outer race, which rests on the frame rails, and an inner race that fits inside the tailshaft housing. The inner race has small rollers that are designed to absorb shock loads, minimise vibration and reduce noise.

When the engine is running, the centre bearing acts as a cushion between the frame rails and the tailshaft housing. If a vehicle experiences excessive levels of vibration or noise, it may be due to worn out centre bearings. This can cause damage to other components in the tailshaft assembly, such as the universal joints and half-shafts.

It's important to note that centre bearings need to be regularly inspected and replaced when necessary in order to maintain effective operation of the tailshaft assembly. If you find that your vehicle is vibrating or making strange noises, it may be time for a new centre bearing.

Replacing the centre bearing is a relatively easy process and can usually be done in the comfort of your own home or garage. However, it's important to find a reputable supplier that stocks high-quality parts, as these can make all the difference when it comes to performance and reliability. With proper maintenance, your tailshaft centre bearing can provide years of reliable service.
