Structural Features & Advantages
- Inch-Series Compatibility: The "20J" suffix is optimized for 1-1/4 inch shafts, perfectly matching inch-standard industrial equipment, ensuring seamless replacement and assembly with existing systems.
- Robust Cast Iron Housing: P207 housing is made of high-strength HT200 gray cast iron, featuring reinforced rib structure for excellent vibration damping and impact resistance, suitable for harsh industrial environments.
- Reliable Set Screw Locking: Two case-hardened alloy steel set screws provide firm shaft clamping, effectively preventing shaft slippage under vibration or frequent start-stop conditions, enabling easy installation and disassembly.
- Efficient Sealing Protection: Double nitrile rubber (NBR) lip seals combined with a metal slinger form a dual protection system, which reliably retains internal lubricant and blocks external dust, debris and moisture, extending bearing service life.
- Excellent Self-Aligning Capability: The spherical outer diameter of the UC207-20 insert bearing allows ±2° angular misalignment compensation, effectively absorbing shaft deflection or installation errors, avoiding additional stress on the bearing.
- Low-Maintenance Design: Factory pre-lubricated with long-lasting lithium-based grease, no additional lubrication is required before initial use. Equipped with a standard grease fitting for easy re-lubrication during maintenance.
Applications
As an inch-series pillow block bearing unit, UCP207-20J is widely used in inch-standard industrial equipment requiring stable radial load support:- Agricultural machinery (augers, hay balers, grain elevators)
- Material handling systems and conveyor lines (inch-standard)
- Food processing and packaging machinery
- Industrial fans, blowers and air compressors
- Woodworking and metalworking machinery
- Mining and construction auxiliary equipment
