Introduction to UCP201, UCP202, and UCP203 Pillow Block Bearings
Pillow block bearings are essential components in machinery,
designed to support rotating shafts while providing durability and
ease of installation. The UCP201, UCP202, and UCP203 are popular models of pillow block bearings widely used across
industries. These units combine a robust housing with high-quality
bearings, ensuring reliable performance under varying loads and
environmental conditions.
UCP201 Bearing
UCP202 Bearing
UCP203 Bearing
| Bearing Type | Pillow block bearing with spherical roller | UCP201: Light-duty; UCP202: Medium-duty; UCP203: Heavy-duty |
| Housing Material | Cast iron (corrosion-resistant) | All models share the same housing material |
| Seal Type | Double-lip rubber seals (standard) | UCP203 includes reinforced seals for harsh environments |
| Bore Diameter | Metric sizing (12–40 mm range) | UCP201: 12 mm; UCP202: 15 mm; UCP203: 17 mm (varies by exact model) |
| Load Capacity | Radial and axial load support | UCP203 offers the highest dynamic load rating (~20% > UCP201/UCP202) |
| Alignment | Self-aligning design | UCP203 has wider misalignment tolerance (±3°) vs. ±2° for UCP201/UCP202 |
| Typical Use | Shaft support in machinery | UCP201: Low-speed applications; UCP202: Moderate speeds; UCP203: High-stress |
These pillow block bearings are ideal for applications requiring reliable shaft mounting, alignment flexibility, and resistance to dust/moisture. Select UCP201, UCP202, or UCP203 based on load requirements and operational conditions to optimize machinery performance.
Below is a summary of precision, grease, and clearance specifications for pillow block spherical bearings, formatted in English with technical terms12.
| Precision | Refers to dimensional and geometric accuracy (e.g., bore diameter tolerance, raceway roundness). | - ISO 492: Class P0 (Normal), P6 (Higher), P5 (Precision)27. | Higher precision (P5/P6) reduces vibration and noise in high-speed applications2. |
| Grease | Lubricant type and filling ratio for bearing operation. | - Grease Type: Lithium-based (general-purpose), polyurea (high-temperature)57. - Filling: 30–40% of housing cavity5. | Over-greasing causes overheating; under-greasing increases wear5. |
| Radial Clearance | Internal gap between inner and outer rings under uninstalled conditions. | - Standard Range: C3 (greater clearance) for thermal expansion compensation17. - Example: 0.015–0.285 mm (ball bearings)1. | Adjust clearance based on load and thermal conditions17. |
| Axial Clearance | Allowable axial displacement between rings. | - Self-aligning design: Compensates ±2°–3° misalignment27. | Critical for applications with shaft deflection or mounting errors7. |
