Covering
Injected polyurethan, hardness 55 Shore D.
Wheel centre body
Polyamide-based technopolymer (PA). Resistant to solvents, oils and other chemicals.
Bore
Directly made into the centre.
Axle set
Calibrated precision tube. The tube serves as a spacer, is tightened to the bracket with screw and nut to a un predetermined torque value.
The wheel bore rotates onto the tube freely.

Fixed plate bracket
Zinc-plated steel or stainless steel (SST version) 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.
Turning plate bracket
Zinc-plated steel or stainless steel (SST version) 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.
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. 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.
Front-actuated brake
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 or stainless steel (SST version) spring.
Applications
Excellent smoothness and elasticity features, good wear and tearing resistance.
Environmental conditions
Suitable for use in environments with the presence of atmospheric agents, alcohols and glycols; weak organic and mineral acids, water and saturated vapour.
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.
