Solve heavy truck suspension problems with ATRO rotating pin polyurethane bushings. Rubber bushings fail due to bushing wind-up, dry-out, cracking, chemical damage, and fatigue under repeated stress.

ATRO’s polyurethane delivers superior durability and reliability and won't fail when exposed to chemicals or weather.

Our exclusive rotating pin design has a full 360-degrees of rotation to make installations faster and simpler.

Featured Product: PB46-26268 Pivot Bushing

Engineered specifically to counter the problem of spring eye wear and “walk-out” in leaf spring applications.

What it does:

• The free-rotating pin prevents the entire bushing from turning inside the spring eye, eliminating “walk-out” wear and damage to the leaf spring eye housing.
• A flanged outer sleeve limits lateral travel, giving additional containment and stability.
• It is applicable to multiple heavy-duty suspension systems (e.g. FASII/Airliner, International Corporate Air/IROS, KW AG400L, Peterbilt New Low Mount Air Leaf)

Because the rotating pin handles torsion, the bushing remains stable in both static and dynamic loading, preserving integrity and alignment over many cycles.

Additional Bushing Solutions from ATRO

ATRO offers a full suite of polyurethane bushings for heavy-truck suspension systems:

• Spring eye bushings for walking beams, leaf springs, and tandem suspensions
• Torque rod bushings with rotating-pin designs built into ATRO torque rods or retrofitted
• Bar pin and pivot kits (for example, EB50-21013 bar pin bushing kits) using rotating-pin technology for easier installation and alignment control
• Complete suspension kits that combine bushings, pins, hardware, and matching components to restore system functionality

Each component is engineered with ATRO’s proprietary polyurethane blends tailored to wear, vibration, load, or high-temperature environments.
