High-Quality China UCP Bearings for Industrial Power Transmission

UCP Bearings: The Core Support for Industrial Power Transmission

Short Description:

The outer ring of the UCP bearing features a spherical design that mates with the concave surface of the bearing housing. This structure enables the compensation of axial misalignment within a range of 0.5° to 2°, thereby accommodating various installation conditions. The integrated construction simplifies the assembly process and allows for individual replacement of bearing components during maintenance, thus reducing both maintenance time and associated costs. The double-sided contact seal effectively prevents dust ingress, making the bearing suitable for use in dusty environments. Additionally, the UCP bearing is capable of operating reliably under temperatures ranging from -30°C to 120°C, which ensures its applicability in high-speed and heavy-load applications.

factory3 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)
