Why specify PU
Six measurable advantages that operators, fitters and engineers tell us they feel from the first kilometre — and continue to feel long after rubber has failed.
Engineered polyurethane outlasts OEM rubber by a factor of three to five under daily load.
Tighter chassis response, sharper steering and reduced wheel hop under hard cornering.
Resists oils, greases and solvents typical of mining, agriculture and heavy machinery.
Stable performance from cold starts to high-temperature continuous duty cycles.
Maintains suspension geometry under load, preserving alignment and tyre wear.

About PolyForge
As a trusted polyurethane distributor based in Johannesburg, we supply specialized workshops, heavy commercial fleets, and industrial operations SA-wide. We stock the premium polyurethane bushes South Africa requires to eliminate premature suspension failure on rugged roads. Our distribution network ensures rapid supply across major industrial hubs including Pretoria, Durban, Cape Town, Port Elizabeth, and Bloemfontein.
From a single LDV in a backstreet workshop to fleets running corrugated mine roads, we supply the same grade of polyurethane components — selected for the conditions South African vehicles and machinery actually face.
Polyurethane vs Rubber
Rubber bushings were designed around comfort and compromise. Polyurethane was designed around load, life and precision. Here’s how they actually compare in service.
FAQ

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.
