TF - Parallel Shaft Helical Geared Motor This series is compact and easy to mount. Flange-, foot- and hollow shaft-mounted versions, or combinations of these mounting options are available. These gearboxes are of a modular design. Output shaft and flange can be mounted to standard hollow-shaft gearboxes without modification of the gearbox. The housing has mounting points on both sides, allowing mounting from either side. The hollow-shaft gearboxes have new mounting options also for the input side. Input possibilities are standard (IEC B5 or B14), direct coupled or with solid input shaft. A combination with other gearbox types is possible with minimum change. In applications where efficiency and strength are important, hollow-shaft gearboxes are preferred to worm gearboxes. Hollow-shaft gearboxes can withstand higher overhung loads than other gearbox types.

Mill scale, is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling hot iron or steel billets in rolling or steel mills. It looks like a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in color. Being produced during the reheating, conditioning and hot rolling operation for the production of steel articles, the mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break occurs in this coating. From the chemical and physical analysis performed on the scrap, and according to the european environmental rules, the material has been classified as a special non dangerous waste, listed in green list In particular the mill scale can be classified as follows: Einecs (european commission no.): 266-007-8 Waste code: 10 02 10 Basel code: b 12 30 Hs code: 2619.00
