Electrical resistivity < 109 Ω.
Wheel centre body
Pressure die-cast aluminium.
Standard executions
- RSL: zinc-plated bearings.
- RXL: stainless steel bearings.
Rolling action
Hub with shielded ball bearings. Ideal solution for heavy loads and continuous moving.
General information
Applications
Excellent rolling resistance and elasticity features, high wear and tearing resistance.
For selection parameters see Technical data.
RE.F5-ESD wheels are supplied also with bracket:
- RE.F5-N-ESD: wheels with steel sheet bracket to be used for light loads.
- RE.F5-H-ESD: wheels with steel sheet bracket to be used for medium-heavy loads.
Environmental conditions
Suitable for use in environments with the presence of atmospheric agents, alcohols and glycols, use in environments with the presence of organic and mineral acids, basic solutions and saturated vapour is not recommended.
Rolling resistance - force / load applied
For each load and diameter, the table indicates the force (in N) needed to push or pull a single wheel at a constant speed of 4 km/h on smooth ground.
For manual handling of a 4-wheel trolley, it is recommended to choose diameters with values below 50 N; for frequent handling, choose values below 30 N.

Mechanical moving with towing devices
For mechanical towing, please see the technical specifications to determine the capacity variation.
Temperature
If operating temperatures in an application differ from the standard range of values, please see the technical specifications to determine the capacity variation.
Features and applications
The special polyurethane with electrical resistivity <109 Ω prevents the accumulation of electrostatic charge. RE.F5-ESD wheels are therefore suitable for applications in "ESD PROTECTED AREAS" where all components sensitive to electrostatic discharges must be treated with the minimum risk of damage.
The electrical specifications meet the requirements of the ISO 22878:2004 standard. The electrical resistivity values indicated have been measured in the temperature range 18-25°C (as per regulations). For environments with operating temperatures below 10°C, contact ELESA sales service.
