污水处理-1 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)
