Precision Cross Universal Joint Coupling – CPCA/CPCW Series

Factory Direct from Guangdong, China | 42CrMo Alloy Steel | ISO Standard | H7 Precision Bore | Single / Double / Telescopic | Custom Splines & Keyways

Product Overview

The Precision Cross Universal Joint Coupling from Apexcoupling is a high‑performance power transmission component designed for accurate torque transfer between shafts at an angle. Manufactured in Dongguan, Guangdong, China, this coupling is available in multiple series including CPCA/CPCW, CPKA/CPKW, CPWA/CPWW, and CPSP to cover a wide range of industrial applications.

Made from 42CrMo alloy steel with a black oxide (blackening) finish, this universal joint coupling offers exceptional strength, wear resistance, and long service life. The H7 precision bore ensures high concentricity and smooth rotation, while the built‑in bearing and fixed pin allow continuous operation within 30° and a limit angle of 45° per joint. For corrosive environments, 304 stainless steel construction is available, with optional nickel plating, zinc plating, or polishing.

The CPWA/CPWW series is a small cross‑shaft universal coupling suitable for two shafts in the same plane with an angle ≤45°. It transmits nominal torque from 11.2 to 1120 N·m and is available with sliding bearings (up to 1000 rpm) or needle bearings (up to 4000 rpm). The CPSP series adds a telescopic spline to connect larger shaft distances, with H7 bore tolerance and optional keyway, hexagon, or square bores.

With ISO certification, IP65 protection, and a 1000‑hour maintenance interval, this precision universal joint coupling is the ideal choice for factory automation, CNC machines, packaging equipment, and general industrial drives.

CPWA / CPWW Small Cross‑Shaft Universal Coupling

• Suitable for connecting two shafts in the same plane with an axis angle β ≤ 45°.

• Transmits nominal torque from 11.2 to 1120 N·m.

• CPWA is single joint; CPWW is double joint. Each joint has a limit rotation angle of 45°.

• Available with sliding bearings (up to 1000 rpm) or needle bearings (up to 4000 rpm).

• Optional quick locking.

• Bore connection: plain round hole, hexagon hole, square hole.

• High concentricity and long working life.

CPSP Telescopic Small Cross‑Shaft Universal Coupling

• Maximum rotation angle per joint: 45°.

• Connects larger shaft distances.

• Finished bore tolerance: H7; keyway, hexagon hole, and square hole available on request.

• Installation length L and stroke X calculation:

  • Stroke X ≤ (Lmax − 2·L2 − B) / 2

  • Lmin ≥ (Lmax + 2·L + B) / 2

  • Minimum dimension Lmin = L2 + B + X + L2
