Aerospace Shock Absorbing Swivel Caster Manufacturer

Product Features & Engineering Specs

Vibration-Dampening HR Polyurethane: Our 95 Shore A High-Rebound polyurethane is chemically engineered to dissipate high-frequency floor chatter, providing a second layer of protection alongside the mechanical springs.

Maintenance-Free Kingpinless Swivel: High-value aerospace loads are heavy. Our kingpinless raceways eliminate the weak center-bolt, ensuring effortless swiveling and zero maintenance in 24/7 assembly environments.

High-Speed Towing Stability: Designed for power-towed applications on airport tarmacs or factory floors, the integrated suspension prevents "caster shimmy" and cart swaying at speeds up to 6–8 mph.

Precision Sealed Ball Bearings: Every wheel is fitted with dual sealed precision ball bearings to minimize rolling resistance and ensure a maintenance-free service life in clean-room environments.

Corrosion-Resistant Finish: All steel components are heavily zinc-plated or can be upgraded to stainless steel for use in chemical washdown or outdoor aerospace hangers.

Why Choose AstraRoll?

Precision Engineering & Asset Safety
Custom Spring Calibration: We provide an engineering consultation to match the spring tension to your specific payload weight, ensuring the suspension "floats" perfectly under your exact operational conditions.
Aerospace-Grade Durability: Our rigs are constructed from high-tensile, cold-rolled steel with hardened swivel raceways, built to withstand the rigorous safety standards of aerospace ground support equipment.

Customization for Specialized Labs
ESD-Safe & Non-Marking: For satellite and semiconductor clean rooms, we offer conductive polyurethane treads that prevent static discharge while ensuring your floors remain pristine.

Frequently Asked Questions (FAQ)

Q: How do I know which spring capacity to choose?
A: This is critical. If the spring is too strong, it won't compress, and your cargo will feel the shock. If it's too weak, it will bottom out. We recommend choosing a spring capacity where your average load weight sits at roughly 50-70% of the spring's maximum compression limit.

Q: Can these be used for outdoor towing on tarmac?
A: Yes. These casters are excellent for outdoor use because the suspension handles the cracks and transitions of tarmac far better than rigid casters. For high-speed outdoor towing, we recommend our 10" or 12" models with tapered roller bearings.

Q: Do shock-absorbing casters require more maintenance?
A: Our kingpinless swivel designs are maintenance-free. However, we recommend a visual inspection of the springs once every 6 months in high-cycle environments to ensure the tension remains optimal and the hardware is secure.

Q: Will these casters lower the overall height of my cart?
A: Actually, shock-absorbing casters are typically taller than standard casters because of the spring housing. If you have strict height clearances, please consult our engineering team so we can provide a low-profile shock-absorbing solution.
