Under normal road conditions, expect 120,000 to 250,000 km — typically three to five times the service life of OEM rubber bushings, depending on load, climate and grade.
For performance, durability and load handling — yes. PU holds suspension geometry, resists oils, and survives heat cycles that destroy rubber. Rubber still wins on absolute ride softness; PU wins on everything else.
Most of our bushings are designed to be greased on installation with a PU-compatible silicone grease. Beyond that, they’re maintenance-free for the duration of their service life.
Yes. We supply PU components into mining, agriculture, heavy plant and manufacturing environments where rubber simply does not survive.
Watch for clunking over bumps, vague steering, premature tyre wear or visible cracking. If you can see daylight through a bushing or feel play in a joint, it’s time.
Yes. We hold local stock and ship nationwide, with same-day dispatch on most line items for trade accounts.
Why modern automotive and industrial systems prioritize high-grade polyurethane elastomers over traditional rubber and plastics.
Polyurethane is highly resistant to wear and abrasion, often lasting significantly longer than rubber, plastics, or even metal in demanding applications.
It provides excellent resistance to oils, solvents, grease, fats, and gasoline, making it suitable for harsh industrial chemical environments.
Compared to conventional rubber, polyurethane can withstand much heavier loads. This makes it ideal for load wheels, heavy-duty couplings, shock pads, expansion joints, machine mounts, and metal-forming pads.
Exhibits exceptional tear strength, ranging from 100 to 1000 lbs. per linear inch, greatly outperforming standard rubber materials. Commonly used for drive belts, diaphragms, roll covers, cutting pads, gaskets, and chute liners.
It offers outstanding resistance to ozone, oxygen, sunlight, and general environmental exposure, ensuring long-term stable outdoor performance under heavy UV conditions.
Hard polyurethane materials are often used in gears where quieter operation is required, while softer grades help improve mechanical vibration and sound dampening compared to standard rubber seals.
Many formulations provide excellent flexibility and fatigue resistance, outlasting other elastomers in applications requiring repeated complex movement like bellows, dust boots, diaphragms, belts, and couplings.
