Mounted Bearings & Housed Units
Pillow blocks, flanged units, and take-up bearings — all major brands sourced. Fast quotes, competitive pricing from an independent supplier.


Mounted Bearing Types We Stock & Source
Pre-assembled, ready to install — housings and bearing inserts in all standard configurations.
Pillow Block Bearings (UCP, SY Series)
The most common mounted bearing. Base-mount housing with a set-screw or adapter-sleeve insert bearing. Used on conveyor systems, fans, agricultural equipment, material handling, and general industrial machinery. Available in standard and heavy-duty cast iron housings.
CST Bearing Co. is an independent bearing supplier in Santa Ana, California, sourcing mounted bearing units from every major manufacturer. Pillow blocks, flanged housings, take-up units — whatever your application needs, we quote fast and ship faster. Mounted units come pre-assembled with a bearing insert and cast iron or pressed steel housing, ready to bolt down. Whether you're replacing a worn pillow block on a conveyor line or speccing take-up units for a new installation, CST has the supply chain to deliver without the big-box markup.
Flanged Bearing Units
Take-Up Bearings (UCT Series)
Square flange (UCF), two-bolt flange (UCFL), and cartridge flange (UCFC) configurations for vertical, horizontal, or through-bore mounting. Used where base-mount isn't practical — overhead conveyors, vertical shafts, machine frames, and packaging equipment.
Sliding-frame housing that allows shaft position adjustment for belt or chain tensioning. Essential for conveyors, material handling systems, and any application requiring periodic re-tensioning. Available in standard and wide-slot configurations.
Insert Bearing Options
The bearing inside the housing matters as much as the housing itself.
Set-screw locking (UC series) — the standard for most industrial applications. Two set screws grip the shaft directly. Easy installation and replacement.
Eccentric locking collar — a collar ring locks the bearing to the shaft without set screws contacting the shaft surface. Preferred when shaft damage from set screws is a concern.
