New, larger output bearings allow users to choose increased shaft diameters than the previously available series. In addition, the large bearings ensure a much extended service life.
The aluminium permanent mould casting process was optimised for the SMI series, resulting in an especially smooth surface that prevents dirt build-up. Closed SMI worm gear versions are wash down-capable, and can therefore be easily cleaned along with other systems during plant cleaning processes.
If required, these 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 aluminium material, providing excellent 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.
The worm gear units provide transmission ratios between i=5:1 and i=3000:1. Thanks to the modular design, they are easily configured according to application requirements. Users can optionally select the field-proven and extensive SI series modular worm gear unit program which is flange-compatible to the SMI series, allowing for very versatile configuration.
On the drive side, several standard IEC interfaces (B5/B14) are available for every gear unit size. The worm gear units can be foot- or flange-mounted and equipped with solid or hollow shafts, and as closed or open frame versions.
