The SNU-U worm gear unit is a high-quality replacement for the Elecon SNU Modular Universal Mounting 4 SNU-U worm gear unit. It is designed with large ribs that increase the heat dissipation area. The streamlined oil sump can hold more oil, and the larger fan improves the gearbox's thermal rating. All of these features result in increased continuous load capacity without a significant rise in temperature. The unit can be replaced without opening the gearbox, simply by moving the fan and fan cover from one end of the worm shaft to the other.

The gearbox casing is made of strong and durable fine-grain cast iron. It is completely oil and dust-proof, allowing for outdoor installation without the need for separate covers. The surface and bores are precision-drilled and machined using the latest precision machinery to ensure perfect alignment and interchangeability.
The worm is made of carburized alloy steel that has been ground and polished. It is integral with the shaft, and the bearing journals are precision-ground. The worm wheel is made of centrifugally cast phosphor bronze. The worm is milled on a special worm milling machine, and then undergoes gas carburizing and grinding on an automatic workpiece grinder. The worm wheel is hobbed on a precision gear hobbing machine using high-precision hobs. Each worm wheel is inspected and matched with the main worm to ensure complete interchangeability.
The worm and worm wheel are supported by ball or roller antifriction bearings, which have ample safety margins to withstand sufficient shaft neck and thrust loads. Overhung loads generated by chain or pinion drives are generally allowable because the gearbox and bearings are designed for this. However, complete detailed information should be provided for confirmation. In cases where overhung loads are heavy, additional roller bearings can be provided.
The wheel shaft is made of high-strength carbon steel. Its larger diameter allows it to withstand torsional and bending loads caused by overhung drives.



The single-piece universal housing has top and bottom flanges, as well as a support flange, allowing the gearbox to have a universal mounting position, including low speed, high speed, and vertical positions. Therefore, internal components can be exchanged for all installation positions. To quickly change the installation position from low speed to high speed or vice versa, simply invert the device and change the position of the drain plug, breather plug, and oil level indicator.

| Issue | Cause | Solution |
|---|---|---|
| Excessive noise | Worn gears or bearings | Replace worn components |
| Leakage of oil | Loose seals or gaskets | Tighten or replace seals |
| Overheating | Insufficient lubrication or excessive load | Ensure proper lubrication and reduce load |
| Abnormal vibration | Misalignment or damaged gears | Align components properly or replace damaged gears |
| Failure to engage | Worn or damaged clutch discs | Replace clutch discs |
