    Photos that help

    • Side view of the complete caster
    • Mounting plate or stem
    • Ruler beside the mounting dimensions
    • Any label or part number
    Mount type

    Fractions or decimals both work: 4-1/2 or 4.5. Switch to mm next to Mount type if that is what you measured.

    Slotted holes? Upload a close-up with a ruler, or enter the measurements you can confirm.

    Mounting plate diagram. Solid green arrows mark the outside length and outside width of the plate. Dashed teal arrows mark the bolt-hole spacing, measured from the center of one hole to the center of the next. Hole centers Hole centers Outside length Outside width Outside plate size Bolt-hole pattern

    Outside size is the full plate. Bolt pattern is hole center to hole center, not edge to edge. A ruler in the photo lets us confirm both.

    Overall height is floor to the top of the mounting plate or the base of the stem, wheel included.

    Application
    Add application details (optional)

    No need to work out a per-caster number. We do that.

    Remote & Nationwide · No Site Visit Required

    Submit photos, measurements, mounting details, and load requirements, and CasterHQ identifies or matches the right replacement caster or wheel. Available nationwide, no part number needed.

    Caster identification and replacement matching is a remote service: submit photos, measurements, mounting details, load requirements, and application information, and CasterHQ helps identify or match the correct replacement caster or wheel. Available nationwide with no site visit required.

    Problems We Solve

    • An unknown caster failed and there is no part number
    • The original caster is discontinued and needs a cross-reference
    • Replacements keep arriving that don't fit the mount
    • Mixed casters across a fleet with no standard part
    • Wrong wheel material that marks floors, drags, or wears fast

    How Caster Matching Works

    • Submit photos and measurements through our contact form or by email
    • We identify the mount, wheel, and capacity class
    • We match a current caster or wheel that fits and performs
    • You receive a quoted, PO-ready replacement specification
    • Optional: we standardize the match across similar equipment

    Required Photo Angles

    • Straight-on side view of the full caster
    • Top-down view of the mounting plate or stem
    • Close-up of the wheel tread and any markings
    • A tape measure in-frame for scale on the wheel and plate

    Measurements Needed

    Dimension How to measure Why it matters
    Wheel diameter Across the wheel, edge to edge Sets ride height and capacity class
    Wheel width Across the tread face Affects capacity and floor contact
    Mounting type Plate, threaded stem, grip ring, expanding Determines how it attaches
    Plate size + bolt pattern Overall plate L x W and hole spacing Must match for bolt-for-bolt fit
    Stem size Thread (e.g. 1/2-13, 3/8-16) and length Must match the receiver
    Load per caster Total load ÷ number of casters Sets minimum capacity rating
    Floor type Concrete, epoxy, tile, outdoor Drives wheel material choice

    Stem vs Plate Matching

    Plate casters match by overall plate size and bolt-hole pattern. Stem casters match by thread size, stem length, and retaining-ring spacing. Send the mount photo and one measurement set and we confirm the fit before you buy.

    Wheel Material & Floor Matching

    We match tread to the floor and duty: polyurethane for capacity and non-marking, rubber or TPR for quiet and grip, phenolic for heat and heavy load, stainless rigs for washdown. See our caster wheels for the full range.

    What Happens After Submission

    • We confirm the identification or matched specification
    • You receive a quote and PO-ready part list
    • We flag standardization opportunities for repeat orders
    • For larger fleets, we connect you to bulk replacement planning

    Frequently Asked Questions

    Can you identify a caster from a photo?

    Often yes, especially with a clear side and top photo plus a couple of measurements. Markings on the wheel or rig help, but we can match by dimensions even when there is no part number.

    What if the original caster is discontinued?

    We cross-reference to a current caster that matches the mount, capacity, and wheel so it fits and performs like the original, or better.

    Do I need exact measurements?

    Approximate is fine to start. Wheel diameter and width, mount type, and a load estimate get us close; we confirm exact fit before you order.

    Is this service available nationwide?

    Yes. Caster identification and replacement matching is remote and available nationwide. No site visit is required.

    Can you standardize the match across our equipment?

    Yes. Once we match one, we can build a standard replacement spec across similar assets. See our caster standardization program.
