Product Introduction

UCFU series square flange mounted bearing units consist of UC insert bearing and extended square cast iron flange housing. 4-bolt mounting structure delivers stronger anti-overturning performance compared with standard UCF housing. Set screw locking fixes inner ring onto shaft. Self-aligning design compensates minor shaft misalignment, widely used for heavy-duty side mounting conditions. Different from regular UCF short flange housing, UCFU adopts lengthened flange base for higher moment load resistance. Compare with standard UCF square flange bearing units and UCT take-up bearing units. Browse more high-quality bearing solutions from YJZY brand.

FAQ

What is UCFU series bearing unit?

UCFU is extended square flange mounted bearing unit, equipped with lengthened square cast iron housing and UC insert bearing. It is designed for heavy-duty side-mount scenarios with high anti-overturning requirement.

Difference between UCFU and standard UCF bearing?

UCFU adopts extended lengthened flange housing, providing better anti-moment and anti-overturning performance. Standard UCF uses short square flange housing for general load applications. Internal UC insert bearing structure remains similar.

What mounting way for UCFU bearing units?

UCFU features four-bolt square flange structure for side wall mounting, install on vertical mounting surface perpendicular to shaft direction.

Can UCFU compensate shaft misalignment?

Yes. Spherical outer ring of UC insert bearing matches spherical inner cavity of housing, offers self-aligning performance to absorb minor shaft misalignment.

What is MOQ for UCFU 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
