Precision Torque Transmission: CPWW1 High-Strength Small Cross Universal Joint

The CPWW1 Model Precision Small Cross Universal Joint Series provides a compact, industrial-grade solution designed to smoothly transfer rotational power across misaligned shafts. In precision drive mechanisms and textile automation, minor structural deflections can cause rigid couplings to bind, resulting in component wear. This small cross universal joint balances this stress by employing an ultra-reliable pin & block or needle bearing internal structure. It delivers smooth mechanical power transmission across an impressive maximum working angle of 45 degrees, safeguarding adjacent machinery components from rotational fatigue and uneven torque delivery.

As detailed in the technical specification profile in universal joint coupling, these precision-ground universal joints are machined from premium 42CrMo (42 crmo) alloy steel. To maximize longevity, each coupling undergoes an advanced Blackening surface treatment and is hardened to 50HRC. This robust model provides a standard 10mm Internal Diameter (ID) bore machined to a precise H7 tolerance, safely supporting a rated nominal torque capacity of 11.2 N·m.
