UCFL Series Diamond Flange Mounted Bearings

🎯 Self-Aligning & Compact Diamond Design

UCFL series integrates a precision insert bearing with a diamond (rhombic) flange housing for stable side mounting. Excellent self-aligning performance effectively offsets shaft misalignment and installation errors, ensuring smooth running and reduced vibration.

⚙️ Sturdy Structure & Easy Installation

Built with heavy-duty cast iron housing and double-sided sealed insert bearings, UCFL provides strong radial load capacity, reliable dust and moisture protection, and long service life. Two-bolt design enables fast installation in limited spaces, with set screw locking for stable shaft connection.

🛠️ Extensive Industrial Applications

Widely applied in conveyor systems, agricultural machinery, fans, pumps, textile machines, packaging equipment and general light to medium-duty transmission equipment requiring space-saving and stable flange mounting.

Mounted bearings & pillow block bearings - UCP, UCF, UC series with housing, ready-to-use units for industrial machinery

Pillow Block Bearings, also known as housed bearing units, are pre-assembled units combining high-precision insert ball bearings with robust cast iron or stainless steel housings. Designed for easy installation, reliable operation and low maintenance, these units feature excellent self-aligning performance, effective sealing against dust and moisture, and strong load capacity, making them ideal for a wide range of industrial applications.

Core Advantages

Easy & Fast Installation: Pre-assembled units eliminate the need for separate bearing and housing installation, reducing on-site assembly time.
Self-Aligning Performance: Spherical outer diameter of insert bearings automatically compensates for shaft misalignment and mounting errors, ensuring smooth operation.
Superior Sealing: Multi-labyrinth seals effectively block dust, dirt and moisture, extending service life in harsh working environments.
Wide Compatibility: Available in various housing styles (pillow block, flange, take-up) and shaft sizes, suitable for metric and inch shafts.
Low Maintenance: Equipped with grease fittings for convenient relubrication, supporting long-term continuous operation.

Typical Industrial Applications

Widely used in conveyor systems, agricultural machinery, food processing equipment, fans, pumps, packaging machines, textile equipment, mining machinery, and general industrial transmission systems.
