Fibre bearing refers to a mechanical component that supports a rotating shaft or axle, allowing it to rotate smoothly while minimizing friction and wear. In essence, a fibre bearing is a type of bearing that uses fibre-reinforced materials, such as plastic or composite materials, instead of traditional metal bearings.

Fibre bearings are designed to:

1. Reduce friction: Fibre bearings have a lower coefficient of friction compared to traditional metal bearings, resulting in less heat generation and wear.
2. Increase durability: Fibre bearings are resistant to corrosion, abrasion, and fatigue, making them suitable for harsh environments.
3. Decrease maintenance: Fibre bearings often require less maintenance, as they are self-lubricating and can operate without additional lubrication.
