All measurements indicate the wheel diameter by the tread width.

The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.

W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.

Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.

Standard-Duty Air-Filled Pneumatic Casters (8–10″, Up to 350 lb)

Standard-duty air-filled pneumatic casters with 8 to 10-inch wheels rated up to 350 lb per caster. True pneumatic tires provide maximum shock absorption and traction on rough outdoor surfaces. Ideal for garden carts, hand trucks, and equipment rolling over grass, gravel, and uneven terrain.

Wheel: 8–10″ | Type: Air-filled pneumatic | Load: Up to 350 lb | Application: Light outdoor, garden, and hand truck use

Frequently Asked Questions

What is an air-filled pneumatic caster? ›
A pneumatic caster uses an air-filled rubber tire (like a bicycle tire) that provides maximum shock absorption, traction, and cushioning on rough surfaces.
Do pneumatic tires go flat? ›
Air-filled tires can go flat from punctures. For maintenance-free use, consider flat-free (foam-filled) pneumatic casters instead.
What surfaces are pneumatic casters best for? ›
Grass, gravel, dirt, sand, cracked concrete, and any rough outdoor terrain where standard casters would get stuck.
