4 inch heavy duty PU rigid caster.
The fixed half of the classic two-and-two layout: the same 100 mm PU-on-cast-iron wheel as the braked swivel, in a rigid fork that keeps loaded equipment tracking straight.

Values marked as a class or target are the specification this model is quoted and sampled against. Final confirmed values are stated on the written quotation and verified on the production sample before bulk production.
Rigid casters are the unsung half of every well-behaved cart. The swivel end steers; the rigid end decides whether the cart tracks straight down an aisle or crabs sideways into the racking. This model exists to be paired: it shares its wheel, tread specification and top plate standard with the 4 inch braked swivel, so one drilling pattern and one spare-wheel stock serve the whole machine.
Because a rigid fork has no raceway to hide behind, its quality is pure structure: fork leg thickness, weld quality and axle specification. All three are stated on the quotation and checked on the sample — a rigid caster that bends at the fork under side load is the most common quiet failure in this size class.
Configuration options
- Supplied as matched sets with the braked swivel for two-and-two layouts.
- Bearing alternatives quoted against the same fork.
- Private label packaging under the OEM programme.
What the sample verifies
Before bulk production, the production sample of this model is checked against the locked specification: wheel diameter and — critically — wheel width measured, tread hardness verified, bearing type confirmed, fork and plate thickness measured, and load performance tested per the stated convention (EN 12532 / ANSI ICWM). The approved sample becomes the reference for the shipment, and the order carries batch traceability back to it.

About this model
Why not use four swivels instead?
Four swivels manoeuvre beautifully in tight spaces and wander on long pushes. The rigid pair is what makes a loaded cart track. See swivel vs rigid for layout guidance.
Does it share the swivel model's plate pattern?
Yes — the pair is specified on one plate standard so equipment frames need a single drilling pattern.
Can the rigid fork be supplied in stainless?
For washdown equipment, ask about pairing within the stainless line; rigid companions are part of that range.
Need this caster under your own brand?
Private label, custom packaging and carton marks are available across the range — mention it in the RFQ and the quotation will include the branding steps.
