Product Introduction
We specialize in manufacturing customized flexible pin couplings for general industrial machinery requiring reliable torque transmission and vibration damping. Located in Hebei Province, China, near Tianjin Port, we are a factory-direct manufacturer integrating design, fabrication, installation and service, providing reliable coupling solutions for global customers.
Application Scenarios
Our pin couplings are widely used in:
-
Electric motors and generators
-
Pumps, fans and blowers
-
Compressors and reducers
-
Conveyors and material handling equipment
-
Agricultural machinery and light industrial drives
Product Structure
The flexible pin coupling mainly consists of the following components:
-
Drive Half Coupling – Connects to driving shaft
-
Driven Half Coupling – Connects to driven shaft
-
Elastic Pin Assembly – Nylon/rubber pins inserted into both halves, providing flexibility and vibration absorption
-
Buffer Ring / Collar – Optional component for enhanced damping
