Product Structure
Two 45# Steel Hubs – Precision-machined flanges with bolt holes for tire attachment.
High-Elasticity Rubber Tire Element – Reinforced rubber element with embedded bolts for secure connection.
Bolts & Nuts – Secure the tire element to the hubs.
Keyway & Set Screw – Standard shaft fixation method.
💡 How it works: The LA Type tire coupling consists of two flanged hubs connected by a high-elasticity rubber tire element. Torque is transmitted through the tire element via friction and bolt connections. The rubber element flexes to accommodate angular, parallel, and axial misalignment while absorbing shock and vibration. The tire element can be easily replaced without moving the connected shafts.

FAQ
Q: What is an LA Type tire coupling?
A: An LA Type tire coupling (also known as an LLA tire coupling) is a high-elasticity flexible coupling that uses a rubber tire element to transmit torque between two flanged hubs. It is specifically designed for metallurgical equipment and heavy industrial applications.
Q: What is the advantage of the tire element design?
A: The tire element provides exceptional shock absorption and vibration damping, protects connected equipment from impact loads, and compensates for angular, parallel, and axial misalignment.
Q: What materials are used?
A: The hubs are made of 45# carbon steel with optional surface treatments. The tire element is made of high-elasticity rubber with optional anti-static and fire-resistant compounds.
Q: Does the coupling require lubrication?
A: No. The LA Type tire coupling is maintenance-free – no lubrication required.
Q: What is the operating temperature range?
A: The standard operating temperature range is -20°C to +80°C.
Q: What misalignment can the coupling compensate for?
A: The coupling compensates for angular misalignment (3°-6°), parallel misalignment (up to 6mm), and axial misalignment (up to 8mm).
Q: Is the tire element easy to replace?
A: Yes. The tire element can be replaced without axial movement of the connected equipment, significantly reducing maintenance downtime.
