UCFC Series Round Flange Mounted Bearings

🎯 Self-Aligning & Stable Flange Mounting

UCFC series consists of a precision insert bearing and a heavy-duty round cast iron housing with four bolt holes. It offers strong self-aligning performance to accommodate shaft misalignment and mounting deviation, ensuring smooth and stable operation under continuous working conditions.

⚙️ Rugged Structure & Easy Installation

With a rigid round flange design, this series provides secure mounting and high load capacity. The set screw locking mechanism ensures firm shaft fixation, while effective sealing protects against dust and moisture. Premium bearing steel and durable housing ensure long service life and low maintenance.

🛠️ Wide Industrial Applications

Widely used in conveyors, agricultural machinery, fans, pumps, textile equipment, packaging machines, food processing lines and general light to medium‑duty transmission systems requiring 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.
