Main specifications
Covering
Mould-on polyurethane, hardness 92 Shore A.
Wheel centre body
Cast iron.
Standard executions
- RBL: hub directly made into the centre. The wheel hub is designed to be easily reprocessed to obtain a keyway or housing for clamping. Any further reprocesses on the wheel must be carried out with maximum working temperature up to 80°C, (recommended max limit temperature during normal use of the product) to prevent degradation of the polyurethane coating.Ideal solution for equipment with drive wheels.
- RSL: hub with ball bearings. Ideal solution for heavy loads and continuous moving.
General information
Applications
Excellent smoothness and elasticity features, high wear and tearing resistance.
For selection parameters see Technical Data.
RE.F4 wheels are supplied also with bracket:
- RE.F4-H: wheels with steel sheet bracket to be used for medium-heavy loads.
- RE.F4-WH: wheels with electro-welded steel bracket to be used for heavy loads
- RE.F4-WEH: wheels with electro-welded steel bracket to be used for extra-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.
Other executions
Special executions on request
Hole with keyway in compliance with UNI 6604, UNI 6607 e ISO 2941 (RBL version).
