Features and benefits
Accommodate static misalignment
Alignment needle roller bearings are self-aligning up to 3° of static misalignment.
Low cross section
In applications where less space is available, alignment needle roller bearings offer a compact solution.
High carrying capacity
Owing to their large number of rollers, alignment needle roller bearings have a high load carrying capacity.
