50mm 304 Stainless Steel Polyamide Caster
Features
- Material: 304 stainless steel construction (housing, wheel core, and mounting plate) for maximum corrosion resistance in harsh environments (saltwater, chemicals, high humidity).
- Wheel: PA6 (polyamide) tread bonded to a stainless steel core, combining low rolling resistance with high load capacity (150kg per caster).
- Bearing: Single ball bearing (sealed) for smooth movement with minimal maintenance.
- Mounting: 70×54mm stainless steel plate with 54.5×36mm hole spacing (8.5mm bolt holes) for secure attachment.
- Low Profile: 72mm installation height—ideal for compact carts and equipment.
Function
✔ Corrosion-Proof – Resists rust, acids, and frequent washdowns (food, medical, marine use).
✔ High Load Capacity – Supports 150kg per caster
✔ Smooth & Quiet Rolling – Low-friction bearing reduces noise in sensitive environments.
✔ Hygienic Design – No crevices for bacteria buildup (easy to clean).
✔ Non-Marking – Safe for epoxy, tile, and hardwood floors.
