Low profile heavy duty caster — 3 inch.
When the load is heavy but the mounting height is not there: a 75 mm wheel, 55 mm wide, in a housing only 107 mm tall, rated 700 kg per caster — with a pull-ring brake that locks or frees the wheel in one motion.

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.
Low centre-of-gravity equipment — heavy cabinets, low machinery bases, wide appliances — cannot use a tall caster, and a small furniture wheel cannot carry the weight. This series answers with width instead of height: the 75 × 55 mm wheel spreads the load across a wide contact patch, and the squat housing keeps the overall height at 107 mm while the structure carries 700 kg per caster.
The brake build uses a pull ring: pull the ring and the wheel locks; work the ring back and it rolls. It is the brake style production staff actually use on low equipment, because it can be operated by hand at floor level without a pedal to hunt for. Swivel and brake builds share the plate and table below.

Dimensions in millimetres unless shown otherwise. Values are the series table values; the written quotation confirms the final drawing for your size class before sampling.
Configuration options
- Swivel and pull-ring brake builds mix on one machine — two of each is the standard low-equipment layout.
- For taller mounting points with similar capacity, compare the MC nylon extra heavy duty series.
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
Why is the wheel so wide?
Width is how a short caster carries weight: the 55 mm tread spreads load and resists the sinking and flat-spotting that narrow small wheels suffer under heavy static loads.
How does the pull-ring brake work?
The ring drives the brake mechanism directly — pull to lock the wheel, return it to roll. It locks wheel rotation; for a full swivel lock as well, state it in the RFQ.
Is this a leveling caster?
No — it has no levelling pad. It is a rolling caster for low, heavy equipment. For roll-then-level duty see the leveling line.
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.
