Wscsber®
Wscsber®
Wscsber®: Modified natural rubber, available with or without anti-static additive. Quiet, floor-friendly, highly elastic with good cushioning; low internal heat and excellent flex-crack resistance; can run at very high speeds (as in car tires), but load capacity is comparatively lower.
Typical Operating Conditions
- Typical equipment: light-duty AGV drive wheels; handling equipment in electronics and semiconductor plants, hospitals, offices and retail.
- Load and speed: light to medium loads; can run at high speed.
- Environment: quiet indoor areas, delicate floors; anti-static grade for sensitive areas.
- Low temperature: lowest continuous service limit of the six materials (see table below).

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