Polyurethane Bushings

Here is a list of our standard durometer specifications and our technical brief, to assist you with choosing the correct material.

• FDA Dry Food Approved 20A to 85A
• Static Dissipative material is available in 40A to 85A (other durometers may be available upon request)
• Dual Durometers

Urethane has many benefits over rubber, especially in the consistently high-stress suspension systems in which bushings are often installed.

Urethane tends to have a higher load-bearing capacity, greater tear strength, better compression set, and greater abrasion resistance than rubber. It is also more tolerant of greases, oils, and ozone.

Rubber bushings tend to deteriorate rapidly with age. As rubber bushings become softer and more pliable, they resist the forces placed on them less and less. In a vehicle in particular, this reduced resistance leads to increased movement of suspension components, excessive tire wear, and braking instability. Polyurethane bushings can withstand the elements of the road for the long haul, while rubber bushings can not. When installed in a vehicle, urethane bushings offer more controlled alignment and steering.

Urethane bushings typically cost and weigh less than their metal counterparts. In some conditions, they run longer in harsh environments and under adverse conditions. Bushings can also be manufactured out of a variety of metals like brass, bronze, or steel.
