Covering

Grey anti-trace thermoplastic wheel, hardness 85 Shore A.

Wheel centre body

Polypropylene-based (PP) technopolymer.

Rolling action

Hub with pass-through hole.

Fixed plate bracket

Zinc-plated steel sheet, the bracket is designed to withstand loads up to 1800N.

Turning plate bracket

Zinc-plated steel sheet, the bracket is designed to withstand loads up to 1800N. The presence of a double ball race and direct contact between the plate and the ball race ring with built-in pin ensure excellent manoeuvrability. Does not require maintenance.

It consists of (see Fig.1):

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 ball race,
6. dust seal: RAL 7015 dark grey technopolymer, available only for SBL and SBF executions.

Brake

Total brake that locks the wheel and bracket rotation. The optimised dimensions and the retractable pedal ensure minimal space occupied and maximum actuation ease. Hardened carbon steel spring.
