Caster & Wheel Capacity Rating Guide
Caster and wheel capacities shown are based on normal operating conditions as defined by the Institute of Caster Manufacturers (ICM).
- Normal operating conditions as defined by the ICM consist of manual operations on a relatively smooth surface (such as concrete) with normal minor obstacles.
- All bearings must be properly lubricated.
- Conditions of excessive temperature and/or dirt will reduce ratings.
- Do not exceed the published capacity ratings.
