DPG 45# Steel Split Jaw Coupling – Keyway & Clamping Screw Type

Factory Direct from Guangdong, China | 45# High-Quality Steel | Split Type Design | Keyway + Clamping Screws | H7 Precision Bore | German Polyurethane Spider | Custom Bores Available

Product Overview

The DPG 45# Steel Split Jaw Coupling from Apexcoupling is a high-performance flexible shaft coupling designed for reliable torque transmission, vibration damping, and misalignment compensation. Manufactured in Dongguan, Guangdong, China, this split-type jaw coupling features 45# high-quality steel hubs, a keyway and clamping screw mounting, and a German-imported polyurethane spider.

The split-type (separated) design allows for easy installation and removal without moving the connected shafts, significantly reducing maintenance downtime. The H7 precision bore ensures high concentricity and a secure shaft fit, while the 12.9-grade screws provide powerful clamping force for reliable torque transmission.

The polyurethane spider offers excellent wear resistance, oil resistance, and shock absorption, with a wide adjustable range. The coupling requires no lubrication, has low maintenance requirements, and can operate continuously for long periods. With large axial, radial, and angular compensation capability, this coupling is ideal for medium-to-high-speed applications.

The 45# steel surface is blackened for corrosion resistance, and the coupling is suitable for a wide range of industries including metallurgy, mining, petroleum, chemical, lifting, transportation, light textile, water pumps, and fans.
