2026-06-05

Full guide of UCP200 series pillow block bearings including structural advantages, size range, self-aligning performance and typical industry usage for global machinery buyers and maintenance engineers.

UCP200 pillow block bearing is the most popular two-bolt mounted bearing unit worldwide, assembled with UC spherical insert bearing and integrated cast iron housing. Pre-assembled structure cuts field installation time largely, making it the preferred standard component across light & medium-load industrial fields. This article details product specs, core advantages, applicable working conditions and bulk supply service of full UCP200 range from UCP201 to UCP215.

Core Construction & Key Advantages of UCP200 Series

  • Self-aligning design: Spherical outer diameter of UC bearing insert permits ±2~3° automatic alignment to fix minor shaft misalignment caused by equipment assembly or frame deformation;
  • Set screw locking system: Dual top set screws fasten inner ring tightly onto shaft to avoid inner ring slipping under vibration or frequent startup-stop;
  • Premium raw material: Bearing insert adopts GCr15 chrome steel after quenching treatment, housing uses high-strength HT200 cast iron with strong anti-vibration property; double-side rubber 2RS seal blocks dust, mud and splash water for outdoor & dusty workshop use;
  • Pre-greased & relubricatable: Pre-filled high-temperature lithium grease before delivery, with built-in grease nipple for regular supplementary lubrication to extend service life;

Full Size Coverage

UCP200 series covers metric bore size from 12mm(UCP201) up to 75mm(UCP215), full complete stock for all conventional models including UCP204, UCP205, UCP206, UCP207, UCP208, UCP209, UCP210, UCP212, UCP213, UCP215. Stainless steel customized SUCP200 series is available for corrosion-prone wet environment like food processing and marine equipment.

Widely Used Industrial Scenarios

  • Agricultural machinery: Harvesters, seeders, corn threshers and farm conveyor rollers, resistant to field dust and muddy working environment;
  • Conveyor & logistics equipment: Belt conveyors, bucket elevators, roller lines for mining, cement and packaging production line;
  • Light industrial equipment: Textile looms, drying fans, small water pumps and food processing machines;
  • Construction auxiliary machines: Concrete mixers, small screening equipment and portable transport machinery.

Stock & Custom Supply for Global Buyers

All standard UCP200 pillow block bearings keep sufficient bulk inventory, spot shipment within 1-3 working days for small orders and full-container sea freight for bulk distributors. Custom options include stainless steel housing, high-temperature special clearance C3/C4 insert bearing and non-standard bore size per customer drawing.
