Needle roller bearings

Needle roller bearings are a special type of bearings distinguished by their unique design and application. They feature cylindrical rollers with a relatively small diameter and a high length-to-diameter ratio. Their primary advantage lies in their ability to carry significant loads while occupying minimal installation space. Due to their durability and capability to handle complex loading conditions, needle roller bearings play a crucial role in many advanced mechanical systems.

MTM needle roller bearings are available with baskets (for significant loads) or the following bearing assemblies:
- radial only with the inner ring
- radial bush one-side closed without the inner ring
- radial bush without the inner ring
- combination of a radial needle bearing and an axial ball bearing
