Product Overview

The Poly Gear Couplings – RPG Series are advanced flexible couplings designed to combine the high torque capacity of gear couplings with the maintenance-free benefits of elastomeric materials. These couplings utilize a polyamide (nylon) gear sleeve in combination with metallic hubs to provide efficient torque transmission, excellent damping, and reduced maintenance requirements.

Engineered for reliability and performance, RPG Series couplings are ideal for applications requiring high strength, smooth operation, and lubrication-free performance.

Key Features & Benefits

    Check

    Simple assembly with quick replacement of the sleeve element.

Construction & Material Options

Components:
Metallic Gear Hubs:
• Precision-machined external gear teeth hubs made from steel

Polyamide Gear Sleeve (Internal Teeth):
• High-strength nylon sleeve that meshes with hub teeth

Working Principle:
Torque is transmitted through the meshing of metallic hub teeth and polyamide sleeve teeth. The flexible sleeve accommodates misalignment while providing damping and eliminating the need for lubrication, ensuring smooth and efficient operation.

Advantages
• Maintenance-free with no lubrication required
• Lightweight and corrosion-resistant design
• Reduced noise and smoother operation
• Easy replacement of flexible element
