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" x 1-1/4" Rubber Casters

Diameter: 4 inTread: 1-1/4 inCapacity: up to 275 lbStem: threaded
Thermo rubber (tpr) and rubber casters here serve finished floors and quiet institutional carts. Typical builds show wheel diameters 4 in, thermo rubber (TPR) and rubber treads, and threaded-stem frames. For dual-wheel or wide treads, check fork clearance and swivel radius in tight aisles. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. These light-duty options cover everyday finished floors and quiet institutional carts without jumping to extreme forged series.
