Description
Rotatable welding current transmission for machines and fixtures. The SH is fastened to the shaft with a conical clamping sleeve, so the shaft ends remain free for further feed-throughs such as air, water or hydraulics.
For higher current loads, several devices can be arranged one behind the other on one shaft. Depending on the application, the rotation speed under current load should not exceed 5 rpm. Flexible cables or braided copper strips are recommended for the connection, and the housing must be secured against rotation by stops on the right and left with approx. 2 mm clearance to the terminal lug.
The devices have lubricating nipples and must be relubricated as specified in the operating instructions, using only special grease P 34. A grease gun with special grease P 34, a nameplate with relubrication instructions and fitting and operating instructions are supplied. Repairs may only be carried out by the manufacturer. The use of the electronically controlled grease cup ET 140 is recommended.
Advantages
- Very compact dimensions
- Easy to fit
- Versatile
- Long service life thanks to relubrication
- Shaft ends remain free for air, water or hydraulic feed-throughs
