Built to ISO standards, this product features a built-in grease fitting for convenient lubrication, reducing downtime and extending service life. Whether you're powering conveyors, agricultural machinery, or ventilation systems, the UCP210 delivers consistent torque transmission and vibration damping. Below we detail its key characteristics, technical specifications, and the tangible benefits it brings to your operations.
Key Features & Benefits
- Durable Cast Iron Housing: High-strength gray cast iron resists shock, corrosion, and thermal expansion, ensuring structural integrity in harsh environments.
- Self-Aligning Bearing Insert: The 2210K double-row ball bearing compensates for shaft misalignment up to ±1.5°, reducing stress on connected components.
- Integrated Grease Fitting: Standard lubrication port allows easy re-greasing without disassembly, extending bearing life by up to 30% compared to non-relubricable units.
- ISO Compliance: Manufactured according to international standards (ISO 9001:2015 certified facility), ensuring dimensional interchangeability and consistent quality.
- Low Maintenance: Pre-lubricated at factory, with sealed bearings that minimize contamination ingress – optional dual lip seals available for extreme dust or moisture.
- Easy Installation: Two-bolt base design fits standard mounting holes; supplied with set screws for quick shaft locking.

Frequently Asked Questions (FAQ)
1. What is the shaft tolerance required for the UCP210?
The UCP210 is designed for shafts machined to h7 tolerance (50 mm with maximum deviation 0/-0.025 mm). For slightly undersized shafts, optional adapter sleeves are available.
2. Can this pillow block be used in food processing environments?
Yes, with the optional food-grade grease and stainless steel seals. The standard cast iron housing is suitable for dry or occasional washdown, but we recommend our special coating for frequent sanitation.
3. How often should I re-lubricate the bearing?
Under normal operating conditions (moderate speed, clean environment), re-grease every 3-6 months. For dusty or high-temperature applications, monthly lubrication is advised. The grease fitting accepts standard NLGI #2 lithium grease.
4. Is this bearing interchangeable with other brands?
Absolutely. The UCP210 follows ISO 3228 standard dimensions, making it a direct replacement for most major brands like SKF, FAG, or Timken pillow blocks of the same size.
5. What is the maximum misalignment allowed?
The self-aligning insert can accommodate angular misalignment up to ±1.5° from the center position, which compensates for minor shaft deflection or mounting imperfections.
6. Do you offer a warranty or guarantee?
Yes, we provide a 12-month warranty against manufacturing defects from the date of shipment. Our quality system (ISO9001 certified) ensures that any issues are handled promptly with replacement or credit.
7. What packing method is used for export?
Each bearing is individually wrapped in anti-rust paper, then packed in sturdy cartons with foam inserts. For larger quantities, we use wooden pallets or crates to prevent damage during sea freight.
8. Can I get a sample before bulk order?
Sure. We support sample orders for evaluation. Sample cost and shipping are negotiable, and we can deduct the sample cost from your first bulk order. Lead time for samples is typically 5-7 working days.
