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.


4 Inch (4" x 1-1/4") Industrial Plastic (Polyolefin) Wheels also known as Polyolefin Caster Wheels are injection molded from a blend of polyolefin/polypropeline polymers forming a one piece design that is solid and will not delaminate. Polyolefin Wheels are great for wet and corrosive environments while providing a high impact resistant wheel. Polyolefin wheels are more economical compared to a Phenolic Wheel or a Steel Wheel. These wheels are not affected by chemicals, solvents, oils, blood, grease, and will not absorb water. These wheels are non-marking and light in weight. Black is the standard color on plastic wheels. Industrial Polyolefin Caster Wheels are a great choice if your on a budget but need new wheels. These are not great when rolling over obstacles or debris such as cables or gaps, we would recommend a Thermo Plastic Rubber Wheel if you need more grip to roll over obstacles and debris.
