Covering
Mould-on polyurethan, hardness 95 Shore A.
Wheel centre body
Die-cast aluminium.
Bore and axle
The axle is mounted using a calibrated tube processed to obtain an even surface where roller bearings and spacers are inserted. Screw and nut are tightened to lock the spacer and the roller bearings. Ideal solution for large loads and continuous moving.

Fixed plate bracket
- Standard bracket: zinc-plated steel plate, the bracket is designed to withstand loads up to 4000N. The bracket load capacity is greater than the dynamic carrying capacity of the wheel assembly plus the bracket (see table), this is a further safety feature.
- Bracket type
H: yellow zinc-plated steel plate (test in saline fog chamber above 72h). The bracket is designed to withstand loads up to 7500N. The bracket load capacity is greater than the dynamic carrying capacity of the wheel assembly plus the bracket (see table), this is a further safety feature. Ensures capacities that make it suitable for heavy industrial applications.
Turning plate bracket
The presence of two ball turns and the direct contact between the plate and the ball race ring with built-in pin ensure excellent manoeuvrability and very limited clearance (see fig. 1). Does not require maintenance.
- Standard bracket: zinc-plated steel plate, the bracket is designed to withstand loads up to 4000N. The bracket load capacity is greater than the dynamic carrying capacity of the wheel assembly plus the bracket (see table), this is a further safety feature.
It consists of:
1) fitting plate: electrolytically zinc-plated steel plate;
2) fork: electrolytically zinc-plated steel plate;
3) ball race ring: electrolytically zinc-plated steel plate;
4) central pin: incorporated in the plate, cold reflanged;
5) rotation system: dual grease-lubricated ring of ball;
6) dust seal: RAL 7015 dark grey technopolymer.
- Bracket type
H: the bracket is designed to withstand loads up to 7500N. The bracket load capacity is greater than the dynamic carrying capacity of the wheel assembly plus the bracket (see table), this is a further safety feature. Ensures capacities that make it suitable for heavy industrial applications (see fig. 2).
It consists of:
1) fitting plate: yellow zinc-plated steel plate;
2) fork: yellow zinc-plated steel plate;
3) ball race ring: yellow zinc-plated steel plate;
4) central pin: class 8.8 steel screw and steel nut;
5) rotation system: dual grease-lubricated ring of ball;
6) dust seal: RAL 7015 dark grey technopolymer.
Brake
-
Standard bracket: total brake that locks the wheel and bracket rotation. The optimised dimensions and the retractible pedal ensure minimal space occupied and maximum actuation ease.
In order to optimise the wheel lock in both directions of rotation, the spring is fitted with a dual braking tooth. Hardened carbon steel spring.
-
Bracket type H: dual-effect brake with simultaneous locking of wheel and bracket. Pushing the trolley, the rear brake is not within the operator's reach as it stays under the trolley.
The trolley must be turned to use the device. The brake is simple and effective to use: it is actuated and released by a simple action from the top downward at the tip of two separate pedals, thus ensuring the utmost manoeuvring comfort.
The braking efficacy may be adjusted with a socket head screw M8.
Applications
Excellent smoothness and elasticity features, high wear and tearing resistance.
Environmental conditions
The wheel RE.F5 is 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
The diagram shows the force to be applied to a wheel to keep it moving at the constant speed of 4 km/h, according to the applied load.
The intersection point with a 50N value is the maximum transportable load with a manually actuated 4-wheel trolley; in fact, 200N = 50N x 4 wheels is the maximum force that may be supported by the operator according to the regulations in force regarding work safety.
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.
