5″ x 1-1/4″ Thermoplastic Rubber Wheel Swivel Caster – Select Expanding Stem Size – 350 Lbs Capacity
5″ x 1-1/4″ THERMOPLASTIC RUBBER WHEEL SWIVEL WITH 1/2″ x 13 – 2-3/4″ THREADED STEM – Part#: Q525024MIR
Thermoplastic Rubber Wheels combine the advantages of both a hard & soft tread material in a single wheel, making it one of our favorite caster wheels. Like a hard tread wheel, thermoplastic rubber rolls easily and is very durable. Like a soft tread wheel, it is quiet, protects floors, and has a cushioned ride. These caster wheels also hold up well when exposed to weather, are resistant to chemicals, water, & steam, and reject floor debris. We highly recommend these caster for applications requiring non-marking, floor protective, quiet, and smooth rolling wheels. We would not recommend these wheels for applications that require sitting in one spot for long periods of time under heavy loads.

How to Install Expanding Stem Casters
-
Squeeze element by holding bottom of stem (with a wrench, or by hand in some cases), and twisting the top nut. This will bring the top nut down and cause the rubber element to bulge out.
-
Check to see if caster stem will slip into hollow leg. It should be hard to push into the leg. If it slips in too easily, then you may need to squeeze the element again as described in step one.
-
Once snug in place in the leg, the friction should keep the element from slipping while you tighten it a little more. The caster should now be securely in place. This procedure will work for both round and square leg.
