Family specifications and selection conditions
| Product description | Self-aligning ball bearings, with a tapered bore and seals on both sides, have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are insensitive to angular misalignment of the shaft relative to the housing. The tapered bore facilitates ease of mounting via adapter/withdrawal sleeves. The integral sealing can prolong bearing service life by keeping lubricant in the bearings and contaminants out. |
|---|---|
| Manufacturer features | Ease of mounting via adapter/withdrawal sleeves • Accommodate static and dynamic misalignment • Excellent high-speed and light load performance • Low friction • Integral sealing results in reduced maintenance requirements and prolonged bearing service life |
