UNKW Cross Shaft Universal Joint Coupling – High Precision CSKW Keyway Type

Apex Coupling provides high-performance UNKW Cross Shaft Universal Joint Couplings designed for demanding industrial transmission and general motor applications. As a factory-trade integrated supplier, we focus on delivering high-precision mechanical transmission components with high torsional stiffness and durability.

Key Features & Product Advantages

• Premium 42CrMo Alloy Steel: Manufactured from high-strength 42CrMo alloy steel, these couplings undergo professional heat treatment to achieve superior toughness and fatigue resistance, making them durable under repeated impacts.

• H7 Precision Bore: The internal bore tolerance is strictly controlled within the H7 precision range, ensuring high concentricity, accurate dimensions, and a seamless fit.

• Large Angular Compensation: These joints support a normal working angle of up to 40° for single joints (with a limit angle of 45°), effectively compensating for both radial and angular deviations.

• High Torsional Stiffness & Low Noise: The precise coordination of internal components minimizes backlash, ensuring a tight connection and quiet operation even at high speeds.

• FA Standard Design: Adhering to Factory Automation standards, the built-in bearings and fixed pins allow for high transmission efficiency and rapid response in both clockwise and counter-clockwise rotations.
