Wide Inner Ring Bearing (WIR)
Including triple seal design for severe contamination conditions, stainless steel units for corrosive environments, and high durability bearings for demanding applications.
Wide Inner Ring bearings are based on sealed deep groove ball bearings, but have a spherical shaped outer ring. The spherical outer ring enables the installed bearing to self-align with the shaft and the housing it’s mounted in. Wide Inner Ring bearings have an extended inner ring with locking device, enabling quick and easy mounting onto the shaft.
These bearings are manufactured to suit either Metric shafting or Imperial shafting. There are three series, but only the UC and UK types are manufactured in all three.
The Series are:
- 2 — series Light series
- 3 — series Medium series
- X — series Narrow Outer Ring, Medium series – slightly less capacity than 3 — series.
All other types are only manufactured in 2 series.
