Insert bearings are the replaceable bearing element used inside pillow blocks and flange housings. Use this hub when the housing is good and you only need the insert.
What is an insert bearing?
An insert is a ball bearing with a spherical outer ring designed to sit in a mounted housing, often with set screws or an eccentric locking collar on the inner ring.
- Common series include UC, SA, and SB styles.
- Match bore and locking style to the shaft and housing.
When do you replace only the insert?
Replace the insert when the housing is undamaged and still holds the bearing securely. Replace the full unit if the housing is cracked, egg-shaped, or heavily corroded.
How do insert bearings relate to pillow block and flange units?
Pillow and flange units are housings plus inserts. This hub is the path when you already have a housing and need the matching insert series.
How can maintenance teams order inserts efficiently?
Standardize on the series your equipment uses, stock high-turn bores, and call 863-337-4984 for multi-size bulk lists.
