Core Advantages

Why engineers choose UCP204.

Built around four engineering principles that reduce downtime, simplify installation, and extend service life.

01

Self-Aligning Design

Spherical outer ring tolerates ±2° shaft misalignment, simplifying installation on uneven mounting surfaces.

02

Heavy-Duty Sealing

Triple-lip rubber seals protect against dust, water, and contaminants in harsh operating environments.

03

High Load Capacity

12.7 kN dynamic load rating with through-hardened GCr15 chrome steel for extended fatigue life.

04

Quick Replacement

Set-screw locking design enables fast shaft mounting and minimizes maintenance downtime.
