IV Stand Casters
7/16″ Grip Ring
For IV poles and mobile drip stands. 3″ neoprene rubber tread, swivel only, capacity 135 lb. The classic spec on the steel-tube IV pole base.
Quiet rolling on tile, won’t mark linoleum, easily replaceable with no tools beyond a screwdriver to pry the existing grip ring out.
Shepherd MonoTech
7/16″ x 7/8″ Grip Ring
For medical equipment carts. Shepherd’s medical-grade line at 110 lb per caster. Available with brake (PGE30748WH-MNT33-GG-B) for parked equipment.
Used on patient lifts, mobile diagnostic equipment, dental cabinetry, and lab carts. Antimicrobial-treated tread options on request.
3″ x 1″ Industrial
Round Stem or Plate
Non-medical 3″ x 1″ applications. P&H polypropylene 150 lb on a 7/16″ x 1-3/8″ stem. P&H TPR 150 lb on 0.712″ round stem.
Used on light-duty industrial carts, retail display fixtures, and equipment where the 3″ x 1″ spec matches existing mount but the application isn’t healthcare.
Wheel-Only Replacements
5/16″ Bore
When the caster yoke is fine but the wheel is worn. 4 tread materials — hard rubber, soft rubber, TPR, polyolefin — in the 3″ x 1″ size with 5/16″ hub bore.
About 40% the cost of a full caster replacement. Match the new wheel to your existing yoke width before ordering.
Are these the same as wheelchair caster wheels?
No — wheelchair front casters use a 5/16″ or 3/8″ bolt-through axle and a precision sealed bearing assembly that the chair’s fork holds. The 3″ x 1″ casters here use a TOP-MOUNTED caster yoke that bolts or stems to the underside of equipment. For wheelchair replacement wheels, you need a wheelchair-specific caster from a mobility supplier, not a top-mount caster.
What’s the difference between 7/16″ grip ring and 7/16″ x 7/8″ grip ring?
The first number (7/16″) is the stem diameter — identical across both. The second number (7/8″) on the longer-stem version is the stem length. The 7/16″ x 7/8″ combo is the Shepherd MonoTech medical-equipment spec; the shorter grip-ring-only stem is the IV pole spec. Equipment manufacturer documentation usually specifies which.
Are the medical casters antimicrobial?
Antimicrobial-treated treads are available on the Shepherd MonoTech line as a special-order finish. Standard inventory uses untreated polymer and rubber. For applications requiring antimicrobial certification (long-term care facilities, infectious disease treatment), email info@casterhq.com with your facility’s spec and we’ll source the antimicrobial variant.
What top plate dimensions do 3″ x 1″ industrial casters use?
The non-medical 3″ x 1″ casters with plate mount use the 1-7/8″ x 2-9/16″ standard plate — same plate as 2″ x 1″ casters. The medical IV stand and MonoTech variants use stem mounts and don’t require a plate at all. Email info@casterhq.com if your equipment uses a non-standard plate.
Can soft rubber treads handle daily hospital washdown?
Soft rubber (60A durometer) holds up to standard hospital floor cleaning solutions (quaternary ammonium, dilute bleach, alcohol-based sanitizers) for 5-10 year service life. The failure mode is bearing corrosion from cleaning chemicals entering the bearing race, not the tread itself. Specify sealed bearings on the swivel raceway for daily washdown environments.
How does load capacity compare across the constructions?
IV stand neoprene: 135 lb. Shepherd MonoTech: 110 lb. P&H polypropylene round-stem industrial: 150 lb. Wheel-only replacement: 100-150 lb. The 300 lb upper end on this collection comes from a few specialty configurations — the typical 4-caster medical cart is rated for 4 x 110 lb = 440 lb total, which is more than enough for normal medical equipment loads.
