SA201
The UC series bearings refer to standardized, widely-used pillow block ball bearing units with adapter sleeves. At their core is a deep groove ball bearing featuring a spherical outer diameter (SPB) designed to fit into the matching spherical bore of a cast iron housing. Adhering to metric dimensions, this series is specifically engineered for industrial applications demanding high load capacity, straightforward installation, and dependable performance.

Structure of UC Series Bearings
A typical UC bearing unit comprises the following key components:
- Pillow Block Housing:Typically made of grey cast iron or ductile iron (e.g., UC-P suffix), featuring mounting holes (plummer block base, with bolt holes or tapped holes), providing robust support and stability.
- Outer Spherical Deep Groove Ball Bearing:The bearing has an inner ring designed to fit onto a standard cylindrical shaft (e.g., tolerance h7). Its outer ring features a spherical outer surface that seats within the housing's spherical bore.
- Sealing Arrangement:Equipped with seals on both sides (usually rubber like NBR or FKM) to effectively prevent the ingress of contaminants, dirt, and moisture while retaining internal lubricant.
- Locking Device:Primarily utilizes an adapter sleeve (eccentric or withdrawal type) combined with a lock nut and washer. This unique mechanism allows the bearing to be firmly secured to the shaft using friction, greatly simplifying mounting and dismounting processes. (Note: Some UC variants use a tapered bore inner ring with a tapered adapter sleeve).
Key Characteristics of UC Series Bearings
- Self-Aligning Capability:The spherical fit between the outer ring and housing bore allows the bearing to accommodate small shaft misalignment (typically up to ±3°), compensating for installation errors or shaft deflection.
- Easy Installation and Maintenance:The pre-assembled unit design, combined with the adapter sleeve locking system, enables extremely fast and tool-free mounting/dismounting on cylindrical shafts, minimizing downtime and maintenance costs.
- Superior Sealing:Standard seals offer excellent protection against harsh environments, extending bearing life.
- Robust Load Capacity:The sturdy cast iron housing and deep groove ball bearing construction provide good radial load capacity and moderate axial load capacity.
- Broad Compatibility & Interchangeability:Manufactured to ISO metric standards (IS), ensuring ease of replacement and sourcing of spare parts globally.
Applications of UC Series Bearings
Thanks to their durability, ease of use, and reliable performance, UC bearings are found in a vast array of industries and applications:
- Agricultural Machinery (Tractors, Harvesters, Planters)
- Conveying Equipment (Belt Conveyors, Roller Conveyors)
- Ventilation and HVAC Systems (Fans)
- Material Handling Machinery
- Construction Equipment
- Food and Beverage Processing Lines
- Textile Machinery
- General Industrial Drives (Motors, Gearboxes, Pulleys)
Choosing UC Series Bearings means choosing reliability, cost-effectiveness, and operational efficiency.
