Light Duty Plate Casters (3-1/8" × 4-1/8")

POPULAR LIGHT-DUTY PLATE FORMAT

Light-duty swivel and rigid plate casters built around the common 3-1/8" × 4-1/8" top plate footprint. Frequently specified for carts, fixtures, and equipment bases where consistent mounting dimensions and dependable rolling performance matter.

Select a wheel type below to match floor conditions, noise requirements, washdown/cleaning needs, and service life targets.

Available Configurations

W/ Thermo Rubber Wheels Quieter · floor-friendly · strong indoor institutional choice W/ Poly on Poly Wheels All-poly construction · durable · good for many cart applications W/ Phenolic Wheels Hard wheel · low rolling resistance on smooth floors · carts/racks W/ Polyolefin Wheel Lightweight, chemical resistant · common on service and utility carts W/ Solid Poly Wheels Tough solid poly · strong durability · industrial cart use W/ High Temp Nylon Wheel Heat-capable option · higher noise · verify temperature range by model

Standard Configuration Envelope

Light duty plate caster mounting plate 3-1/8 x 4-1/8 inches, capacity up to 350 lb per caster, wheel options thermo rubber, poly on poly, phenolic, polyolefin, solid poly, and high temp nylon.

Mounting Plate: 3-1/8" × 4-1/8"
Rated Load Capacity: Up to 350 lb per caster (model dependent)
Mounting Styles: Swivel · rigid · brake options (model dependent)
Wheel Diameters: Commonly in light-duty ranges (varies by model)
Wheel Configurations: Thermo Rubber · Poly on Poly · Phenolic · Polyolefin · Solid Poly · High Temp Nylon
Standards & Compliance: ANSI-tested designs · ICWM dimensional standards · NSF-listed models · RoHS-compliant materials · ISO 9001:2015 manufacturing partners

Selection tip: Ratings are per caster under ideal conditions. If your cart crosses joints, thresholds, debris, ramps, or sees impacts, increase wheel diameter or step up one duty class to reduce push force and improve service life.

Selection Guidance

How to confirm replacement fit

Confirm plate size is 3-1/8" × 4-1/8" and verify hole spacing/slotting by model
Match overall height and wheel diameter to maintain clearance
Check swivel clearance near frame edges, welds, and gussets
Confirm brake type (side brake / total lock) if required

Wheel material quick-choose (no fluff)

Thermo Rubber: quieter and floor-friendly for indoor use
Poly on Poly: durable all-poly option for many carts
Phenolic: hard wheel, low rolling resistance on smooth floors
Polyolefin: lightweight and chemical resistant; common utility choice
Solid Poly: tough, durable solid poly for industrial carts
High Temp Nylon: heat-capable option; verify temperature rating by model

When to step up in duty class

Frequent threshold/joint crossings
Dynamic loading, impacts, or ramp transitions
Continuous duty where push force must stay low

FAQ

What are 3-1/8" × 4-1/8" plate casters used for?

Common for light-duty carts, fixtures, and equipment bases requiring a widely used plate footprint and dependable rolling performance.

How much weight can these casters support?

Up to 350 lb per caster depending on wheel material, bearing, and diameter. Real capacity decreases with impacts, debris, ramps, and uneven loading.

Which wheel type should I choose?

For indoor quiet rolling choose thermo rubber. For durable all-around use choose poly on poly or solid poly. For low rolling resistance on smooth floors choose phenolic. For chemical resistance choose polyolefin. For heat applications choose high temp nylon (verify rating).
