Air Compressor Coupling Product Introduction

Product Overview

Our air compressor coupling is a core transmission component specially designed for screw, piston and rotary air compressors. It connects the motor and air compressor host, effectively transmitting torque while buffering vibration, compensating axial, radial and angular misalignment between driving and driven shafts. Built with high-strength wear-resistant materials, it delivers stable power output and greatly extends the service life of compressor main units, bearings and motors.

Key Features

1. Superior Vibration & Shock Absorption Elastic buffer structure absorbs instantaneous impact load generated during compressor startup and operation, reduces equipment vibration and noise, and avoids rigid collision damage to the host.

2. Multi-Dimensional Misalignment Compensation Flexible elastic body offsets shaft position deviation caused by assembly error, thermal expansion and long-term equipment wear, lowering extra bearing friction loss.

3. Long Service Life & High Wear Resistance Elastic elements adopt premium polyurethane/rubber with excellent oil resistance, aging resistance and high temperature resistance; metal hubs are precision cast and machined, not easy to crack or deform under continuous heavy load.

4. Easy Installation & Maintenance Split elastic pad design allows quick disassembly without moving motor or compressor host; no complex lubrication required, greatly cutting daily maintenance cost and downtime.

5. Wide Compatibility & Stable Transmission Supports matching various power air compressors from small industrial models to large stationary screw compressors, with high torque transmission efficiency and no power loss.

Material Options

· Hub: Cast iron / 45# steel (high strength, anti-rust treatment)

· Elastic Cushion: Polyurethane PU / Nitrile rubber NBR (oil-proof, heat-resistant, wear-resistant)

Application Scenarios
