RE.F4-RBL

Mould-on polyurethane wheels

Hub with pass-through hole

RE.F4-RSL

Mould-on polyurethane wheels

Hub with ball bearings

Description

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).
