Helical

Choose from 21 sizes of SEW Eurodrive explosion-proof helical gear units for use in potentially explosive atmospheres. Our helical gear units in II2GD version are the ideal combination of performance and low space requirements. Our explosion-proof helical gear units have equipment group II approval for categorie 2. They drive systems and machines in potentially explosive atmospheres. A total of six single-stage and 15 two and three-stage sizes cover a performance range of 50 Nm to 18,000 Nm. This gear unit series is also far ahead in terms of gear unit ratios: from i = 1.30 to i = 289.74, in double gear units even i = 27,001. Torque ratings and gear unit ratios this finely stepped are hard to find on the market. The R gear units also meet demands for high output speeds and light weight, of course. With a consistently high level of efficiency, our explosion-proof helical gear units offer an optimum ratio between torque output and installation space. Only half the solution without a motor? Then use our sophisticated modular concept and combine the explosion-proof gear units of the R series with the explosion-proof motor of your choice.
