TPR — thermoplastic rubber — is the tread for equipment that lives indoors around people: service carts, laundry and catering equipment, medical-adjacent trolleys, retail and institutional furniture on wheels. It runs quiet, it does not mark floors, and it does not harden and crack the way cheap natural rubber does.
The series shares one plate pattern and one M12 × 30 stem across all sizes, so a mixed fleet stays on one drilling standard. Swivel, rigid and brake builds are available across the range.

What the sample verifies
Before bulk production, the production sample of this series is checked against the locked specification: wheel diameter and — critically — wheel width measured, tread hardness verified where the series states it, bearing type confirmed, fork and plate dimensions 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 series
Is TPR the same as rubber?
It is a thermoplastic elastomer moulded like plastic with rubber-like softness — quieter and cleaner-running than economy rubber, and it will not leave the black marks solid rubber can. It is not the choice for oil-soaked floors; say so in the RFQ if oils are present.
Can I mix plate and stem builds in one order?
Yes — the series is one standard across mountings, and mixed orders are normal.
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.
