China UCP Bearings: Essential Support for Industrial Power Transmission

UCP Bearings: The Core Support for Industrial Power Transmission

Short Description:

The Pillow Block Bearing UCF211 is a spherical plain bearing unit with a housing. The core is the UC211 ball bearing (2-inch inner diameter), pre-assembled in a sturdy cast iron square housing. The base is equipped with four bolt holes for easy installation and fixation. It is designed to support rotating shafts, providing reliable support and is suitable for general industrial applications such as conveyors and agricultural machinery.

zhongkongboli11111111111 Basic Definition & Structural Features
UCP bearings (Pillow Block Bearings with Insert) are pre-assembled units comprising a bearing insert housed within a cast iron or pressed steel pedestal. Key characteristics include:
•Spherical Outer Surface: The bearing outer diameter features a spherical design, enabling ±3° self-aligning capability.
•Pre-sealed Configuration: Standard rubber seals (RS or 2RS configuration) provide IP54-rated protection against dust and water ingress.
•Standardized Housing: Compliant with ISO 113:2015, ensuring cross-brand interchangeability of mounting hole spacing.
2. Operating Principles & Mechanical Properties
2.1 Load Transmission Mechanism
Load transfer occurs through rolling elements (steel balls) between inner and outer rings:
•Radial Loads: Transmitted along the bearing radius (accounting for ~70% of load capacity).
•Axial Loads: Accommodate unidirectional axial forces (≈20% of radial load capacity).
2.2 Tribological Properties
•Ultra-low rolling friction coefficient: 0.001–0.003
•Maximum speed: 3,000 rpm with lithium-based grease lubrication (2,000-hour grease life @ 70°C).
3. Typical Application Scenarios
3.1 Agricultural Machinery
•Combine harvester drive shafts (operating temp.: -30°C to 80°C)
•Irrigation system worm gear reducers (require anti-corrosion coatings)
3.2 Food Processing Industry
•Conveyor belt drive units (FDA-compliant stainless steel variants)
•Crank mechanisms in packaging machines (withstanding cyclic shock loads)
3.3 Mining Equipment
•Vibrating screens in crushers (require supplemental labyrinth seals)
•Belt conveyor idler rollers (special lubrication solutions for dusty environments)
