What Makes the PF Wheel Unique?

Ergonomics meets extreme durability.
The PF wheel is designed to offer the performance of a heavy-duty polyurethane wheel with the added benefits of easy mobility. Its high-performance polyurethane tread, with radius tread, delivers powerful durability, quiet operation, excellent floor protection, and long-lasting, smooth rollability.

Built for the load.
With a precision cast iron core underneath the performance polyurethane tread, the PF wheel can carry heavier loads with less strain, while handling the impacts that lighter duty cores or materials would not be able to handle. It’s optimized for manual and towed applications alike, and thanks to its sealed precision bearings, it rolls quieter and with lower resistance than traditional high-capacity wheels.

Designed for Strength, Optimized for Movement

The PF wheel isn’t just another industrial caster. It’s built with ergonomics, operator safety, and lasting facility efficiency in mind. With reduced push/pull effort and enhanced floor protection, it delivers performance where it counts.

Real Benefits for Operations

Lower Push/Force Requirements
The tread shape and lively material, along with the industrial-grade precision ball bearings (standard in all PF wheels) result in lower operator fatigue compared to traditional polyurethane wheels with roller bearings—especially useful for repetitive, high-load cart movement.

Shock and Impact Resistant
The precision cast iron core doesn't just support weight—it stands up to abuse. These casters are ideal for higher-impact environments like towlines, AGV carts, or rough-surface material handling.

Maintenance-Free Performance
Thanks to sealed precision ball bearings, these wheels operate quietly, cleanly, and consistently—with no need for routine lubrication.

Smooth, Quiet Rolling
The 95A polyurethane tread glides across industrial floors with minimal noise and vibration, even under heavy weight or in towline service.

Long-Term Durability
With a chemically bonded tread and robust materials, PF wheels resist chunking, tread separation, and deformation—even under tough conditions. They are tested to ANSI ICWM standards to ensure lasting safety and performance, and tight quality controls ensure manufacturing processes deliver the highest quality level of industrial wheel.

Applications Where PF Wheels Excel

Manufacturing carts and towline applications
Withstand long duty cycles, uneven surfaces, and repeated shock loading.

Frame, dollies, and other manufacturing process needs
Enhance productivity, reduce force required to move, and enhance safety around manufacturing lines – from transportation, RV, mobile home, or other heavier manufacturing line needs

Work Platforms
Ensure easier movement of larger work platforms.

Lean / JIT Production Carts
Precision steering and quiet operation help streamline efficiency on the floor.

PF vs. Other Heavy Duty Caster Wheels

Feature	PF Wheel	Traditional Heavy-Duty Wheel
Push/Pull Force	Low	Medium to High
Noise Level	Quiet	Medium (hard polyurethane) to Loud (metal)
Floor Protection	Non-marking polyurethane	May damage floor (metal treads)
Shock Resistance	Excellent	Moderate to Excellent (metal)
Maintenance	None (sealed bearings)	Requires greasing/lube (if roller bearing)

Spec Tips & Selection Notes

Ergonomic advantage
Choose PF wheels when heavy-duty ease of movement and safety are top priorities.

Towed or powered?
Perfect for towline carts or power-moved platforms, dollies, carts.

Floor type
Best on concrete, whether finished or not.

When not to use
Contact us if there is a lot of debris that could get embedded, we may want to evaluate your application and debris to ensure long-lasting performance.

Make sure to pair with the best rig for your application:

Kingpinless rigs for best handling of heavy shock loading and impacts – utilize extended leads for standard towed applications (not extreme loads) to make steering even easier and to reduce potential for chatter.

Maintenace-free rigs will give you a completely maintentance-free caster and the best in ergonomic value. These will feature a standard extended lead for the best in ergonomics, but capacities will round out around 2,000 lbs. per caster in this option. Higher load capacities will be accomplished through the kingpinless options.
