Product Introduction

UCFL series flanged bearing units adopt 2‑bolt oval diamond cast iron housing matched with insert ball bearing. Set‑screw locking fixes the inner ring onto shaft. Self‑aligning function compensates minor shaft misalignment. Compact flange structure saves installation space for narrow machine frames. Grease nipple supports re‑lubrication. Widely used for conveyor systems, agricultural machinery, fans and packaging equipment. Different from 4‑hole square UCF housing, UCFL uses two‑bolt oval flange for limited mounting space.

FAQ

What is UCFL series bearing unit?

UCFL is 2‑bolt oval diamond flanged mounted bearing unit. It combines cast iron oval flange housing and set‑screw locking insert bearing, designed for compact‑space installation scenarios.

What is difference between UCFL vs UCF bearing?

UCFL adopts two‑bolt oval diamond flange housing for narrow mounting space; UCF uses four‑hole square flange housing for heavier fixing requirement. Insert bearing structure is similar.

What is locking method for UCFL bearing?

UCFL uses set‑screw locking on inner ring, which fastens bearing onto shaft surface. It is widely used for normal speed non‑repeated frequent reversing working conditions.

Can UCFL bearing realign shaft misalignment?

Yes. The spherical outer surface of insert bearing matches spherical inner surface of housing, achieving self‑aligning performance to compensate minor shaft misalignment.

What is MOQ for UCFL series?

Stock sizes accept small trial orders. Larger dimension models require bulk quantity. Please send your model list and quantity for exact quotation and lead‑time.

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.

We offer a full range of pillow block and mounted bearing units to meet diverse industrial installation and load requirements:

Series	Housing Type	Key Features
UCP Series	Standard Pillow Block (2-bolt)	Most widely used, easy installation, suitable for general industrial machinery, conveyors, fans and pumps
UCT Series	Take-Up Unit (Slotted)	Adjustable housing for belt tensioning, ideal for belt conveyors, textile machinery and packaging lines
UCF Series	Square Flange (4-bolt)	Rigid square flange for side/end mounting, perfect for food processing equipment and automation lines
UCFC Series	Round Flange (4-bolt)	Compact round flange, space-saving, suitable for pumps, fans and light to medium-duty equipment
UCFL Series	Diamond Flange (2-bolt)	Narrow rhombic flange, ideal for limited installation space, small conveyors and agricultural machinery
