Mcnylon® (≥80 Shore D)
Mcnylon® (≥80 Shore D)
Mcnylon®: Modified MC nylon (cast nylon) for very heavy loads at low speed. Low friction and minimal rolling resistance, high compressive strength and stiffness, wear resistant and self-lubricating, resists oils and greases; hard tread for smooth rails and floors.
Typical Operating Conditions
- Typical equipment: ultra-heavy special equipment, heavy transfer cars, crane and rail carriages.
- Load and speed: ultra-heavy loads at low speed; easy pushing and low drive power.
- Environment: smooth rails or hard floors, oily conditions; hard tread, not for rough or high-impact surfaces.

Note: typical values measured on laboratory test specimens, for material selection only; whole-wheel performance depends on wheel diameter, tread thickness and operating conditions.
