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.

B&P Junior Liberator Convertibles (SJR)

This collection holds Bp Junior Convertibles casters with pneumatic and polyurethane wheels, built for shop carts, equipment, and material handling carts that move heavier loads. Casters in this collection range from 500 to 600 lb per caster. Air filled and flat free tires cushion the load and roll over gravel, grass, cracks, and debris. Polyurethane (poly or urethane) treads are quiet, floor safe, and resist water and many chemicals. Match plate size, bolt pattern, and overall height before you order. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you order. Measure the old wheel or caster before you buy. Check the floor type and the heaviest load the cart will carry before you choose. Call or email CasterHQ with the part number from the old unit if you need help matching it. Pneumatic aisle: pneumatic casters. Wheel hub: replacement wheels.
