Tread material drives the floor behavior
Capacity stays consistent across tread materials at this size (90 to 100 lb each) because the wheel diameter is the constraint, not the rubber. Where the choice matters is floor compatibility, noise, and shock absorption.

Confirming a 2″ x 7/8″ fits your existing equipment
Measure with a caliper before assuming it’s the right size
Worn casters often look the same as the spec sheet but are out of tolerance. Pull a GOOD caster from the opposite corner of the equipment and measure that one — not the worn one. Diameter is outside-edge to outside-edge of the tread; width is face-to-face of the hub. 0.875″ reads as 7/8″. If you measure 1.000″, shop our 2″ x 1″ collection instead.
Identify the mount: plate or threaded stem
Top-plate version on this page uses 1-1/4″ x 2-1/16″ (most common) or 1-7/8″ x 2-9/16″ with 4 bolt holes. Threaded stem version uses 3/8″-16 thread at 1″ or 1-1/2″ long. If your equipment uses a 7/16″ diameter stem, you’re looking at an office chair caster — jump over to our Chair Casters collection for the right fitment.
Swivel-rigid pairing depends on cart layout
Standard 4-caster cart pattern is 2 swivel front + 2 rigid rear for predictable straight-line tracking down aisles. All-swivel for tight maneuvering — common on hospital, AV, and prep station carts. Side-lock brake on at least one corner if the cart must stay parked when loaded.
Tread choice is mostly about your floor
Hard rubber works for warehouse, stockroom, and shop floors where slight marking under load doesn’t matter. Soft rubber or TPR for finished commercial floors. Polyurethane for longest service life under continuous use. Polyolefin if cost is the priority and the floor is dry indoor. The wheel-only option exists when the caster yoke and bearing are still in good shape and you just need fresh tread.
Measurement note: The single most common mistake on 2″ x 7/8″ replacement orders is measuring the worn wheel and rounding. A wheel that started at 2.000″ and 0.875″ may have lost 1/16″ on each dimension over years of use — now reading 1.94″ x 0.81″. Buyers see that and order 1-7/8″ x 7/8″ casters that don’t fit. Always measure a fresh wheel on the same equipment if you have one, or refer to the original equipment plate or stem spec (the mount dimension doesn’t wear). When in doubt, email info@casterhq.com with photos.
What buyers ask before ordering 2″ x 7/8″
Will these fit my office chair?
Different spec, but we have you covered. Office chair casters use a 7/16″ diameter stem at 7/8″ long — the “7/8” in “7/16 x 7/8” refers to STEM length, not wheel width. For office chair replacements head over to our Chair Casters — Office, Stool & Replacement collection (50 styles, fits Herman Miller, Steelcase, HON, Secretlab and the rest). The casters on THIS page use a 2″ wheel diameter with a 7/8″ wheel tread width, mounted on a 3/8″-16 industrial threaded stem or top plate — for AV racks, prep stations, retail fixtures, and light shop trucks. Two different specs, same SERP cluster.
What equipment actually uses 2″ x 7/8″ industrial casters?
AV racks and audio-visual rolling stands; small prep stations and food prep tables; hospitality service carts; retail display fixtures and merchandising racks; light shop trucks; medical and dental equipment carts; tool boxes with built-in mobility. The unifying spec is a compact 2-inch wheel that needs to fit under low equipment without raising deck height, with enough capacity (90-100 lb each) to carry four-caster loads of 360-400 lb total.
What top plate dimensions are standard?
Two plate sizes are common on 2″ x 7/8″ casters. The 1-1/4″ x 2-1/16″ plate with 4 bolt holes is the most common modern spec. Older equipment sometimes uses a 1-7/8″ x 2-9/16″ plate — we stock both. Measure your existing mount with a caliper before ordering. The threaded stem version uses 3/8″-16 thread at 1″ or 1-1/2″ stem length.
Is there a heavy-duty version that hits more than 100 lb capacity?
Yes — the TP-60 retractable leveling caster series shares the 2″ x 7/8″ wheel dimension but is a workbench-grade product rated up to 2,400 lb each. The wheel retracts via a handwheel or ratchet handle so the cart sits on a leveling foot when parked. The capacity jump (100 lb to 2,400 lb) happens because the leveling foot carries the load when stationary, not the wheel. Specified for industrial workbenches, machinery bases, and stationary equipment that occasionally needs to roll.
Can I replace just the wheel without the caster body?
Yes. We stock 2″ x 7/8″ wheel-only replacements in all five tread materials — hard rubber, soft rubber, TPR, polyurethane, and polyolefin. Standard hub bore is 1/4″. If the existing caster yoke, swivel raceway, and bearing are still in good shape, swapping just the wheel costs roughly 40% of a full caster and extends service life another 3-5 years on typical industrial duty.
Hard rubber or soft rubber — which one for what?
Hard rubber is approximately 80A durometer — firmer tread, lower rolling resistance, slight floor marking under heavy load on light-colored finishes, full 100 lb rated. Soft rubber is approximately 60A durometer — softer tread, absorbs more vibration, non-marking on finished floors, rated slightly lower at 90 lb. Soft rubber is the spec for hospital, library, and any noise-sensitive application. Hard rubber is the standard for warehouse and shop carts where floor marking is acceptable.
Can a 2″ x 7/8″ caster be swapped for a 2″ x 1″ caster?
Not cleanly. The 1/8″ tread-width difference is too tight to mix — a 7/8″ wheel rattles in a 1″ yoke and the wheel bearing fails prematurely from the lateral slop. A 1″ wheel binds in a 7/8″ yoke. To change wheel width you replace the entire caster, not just the wheel. The top plate dimensions are often identical between the two sizes so bolt holes line up — verify before ordering.
