High performance worm gear units from Nord

Available in a robust, one piece UNICASE housing with a maximum torque of 427Nm, the larger output bearings are said to ensure a much extended service life and allow users to choose increased shaft diameters. The aluminum permanent mould casting process was optimised specifically for the new series, resulting in a smooth surface that prevents dirt build-up. Closed SMI worm gear versions are washdown-capable and can therefore be easily cleaned along with other systems during plant cleaning processes. If required, the gear units are available with NORD's NSD tupH surface conversion treatment, which transforms their durability with up to seven times the hardness of the base aluminum material, providing protection against acids and alkaline solutions. A synthetic long life lubricant makes the worm gears maintenance free during their entire service life. Equipped with oil gauge screws, the gear units are now also suitable for use in hazardous areas.
