Series SGZD, Standard version

Technical Specifications
Heavy duty welded steel brackets, grey (RAL 9007) lacquer coated.
Castor suitable for peak-loads.

Load capacity GK1 and GK2 from 1100 up to 1900 kg.
This extremely sturdy steel welded series, containing three legs for assembly with twin wheels, is build up with heavy lasered and machined steel parts. The swivel head has a steel hardened axial grooved ball bearing and a steel hardened tapered roller bearing. Types GK 1 and GK 2 have a heavy top plate with double round-welded heavy solid steel king pin. Remaining types have a very heavy machined housing, with machined seats, which is round-welded on a heavy top plate. The swivel-legs are welded on the solid steel machined swivel-discs with the use of an in-between bridge, at the types GK 1 and GK 2. As to the other types the swivel-legs are welded on the heavy solid steel machined swivel-disc which forms a whole with the central king pin, with the use of an in-between bridge. To avoid loosening, the central nut is welded after adjusting. By means of an O-ring the bearings are protected against dust and dirt and the types GK 3, 4 and 5 at the same time have a thermoplastic cap to plug the hole in the topplate. To protect against environmental influences these brackets are hammer-blow grey lacquer coated. The swivel head is smooth running and has no play. The bearings are lubricated with durable grease. On request a grease-nipple can be fitted. The legs of the swivel- and fixed brackets are all round welded. Temperature range from -30° to +80°C.
These very robust heavy duty twin-brackets are under normal conditions maintenance-free and have an extremely long service life. Moreover the swivel resistance is reduced to the minimum because of the differential effect when using twin wheels. Specials; for instance brake-version or directional lock as well as brackets with different dimensions, are available on request.
Purposes at intensive normal use in the heavy segment, where very regular peak-loads appear in combination with very heavy loads and long-life, failure-free operating is demanded, justify the use of these brackets.
