Polyurethane Bearings

 

Polyurethane bearings are advanced components designed to support rotating, sliding, or oscillating elements in machinery while reducing friction and wear. Unlike traditional metal or rubber bearings, polyurethane bearings offer a unique combination of properties ideal for challenging environments and high-performance applications.

 

Composition and Structure

 

Polyurethane bearings are made from a versatile polymer known as polyurethane, formed by reacting diisocyanates with polyols. This chemical reaction results in a material with exceptional mechanical properties, including:

 

– High tensile strength

– Excellent abrasion resistance

– Flexibility and resilience

– Chemical resistance

– Load-bearing capacity

 

The structure of a polyurethane bearing typically consists of:

 

1. A polyurethane outer layer

2. A metal or plastic inner core (in some designs)

3. Optional reinforcements or additives for enhanced performance

Manufacturing Process

 

Shree Shakti Industries employs several manufacturing techniques to produce high-quality polyurethane bearings:

 

1. Injection Molding: Ideal for high-volume production of precision bearings

2. Casting: Used for larger bearings or custom shapes

3. Custom Machining: For specialized or low-volume orders

4. Urethane Coating: Applying a polyurethane layer to existing bearings

 

Each method is carefully selected based on the application’s requirements, ensuring optimal performance and longevity.
