Overview
The RAK UC205-25MM pillow block bearing is a precision-mounted bearing unit designed for industrial shaft support applications. The unit combines a UC205 chrome steel ball bearing with a one-piece cast iron P205 housing, providing durable alignment and smooth operation across a wide range of machinery types. The 2-bolt base configuration allows for straightforward installation on mounting surfaces.
Key Features
- 25mm bore diameter accommodates standard cylindrical shafts
- Two-bolt mounting base for secure, rigid installation
- Set screw locking device prevents shaft slippage during operation
- Cast iron P205 housing provides strength and corrosion resistance
- UC205 chrome steel bearing enables efficient operation at varied speeds
- Self-aligning design reduces abnormal bearing loads and shaft misalignment effects
