View SSGM-090Why Choose the SSGM Machined Stainless Series
The SSGM series differentiates itself from conventional cast-body stainless worm gearboxes through six key engineering choices. These define the premium positioning of the SSGM line for specifiers who demand both performance and appearance.
Six-Sided Fully Machined Body
Every external face of the SSGM housing is precision machined, not cast. The resulting surface quality is superior to cast-body stainless gearboxes — eliminating cast porosity, providing flat reference surfaces for bracket mounting, and delivering a premium show-quality aesthetic.
Solid 304 Stainless Throughout
Housing, wheel core, and output shaft are all manufactured from 304 stainless steel. No painted surfaces to chip, no aluminum to corrode, no hidden carbon steel components that could create galvanic corrosion initiation points.
12-2 Tin Bronze Worm Gear
The bronze worm gear paired with a hardened steel worm shaft delivers quiet operation, low friction, excellent wear resistance, and natural corrosion compatibility with the stainless housing — extending service life across continuous-duty cycles.
Fully Synthetic Worm Gear Oil
Factory-filled synthetic lubricant provides superior thermal stability, reduced internal friction, improved cold-start performance, and extended oil-change intervals compared to mineral oils — lowering total maintenance cost.
Widest SSGM Range: SSGM-030 to SSGM-090
Six frame sizes cover from laboratory micro-drives to flagship petrochemical service — the widest stainless worm gearbox range in the market, all built to the same machined-body engineering standard.
Multi-Directional Mounting
Every SSGM size supports foot, flange, and torque-arm mounting orientations. The machined square body actually simplifies bracket fabrication compared to rounded cast housings — a frequent preference of system integrators.

Frequently Asked Questions
Common questions engineers and procurement professionals ask when specifying SSGM stainless steel worm gearboxes for hygienic and corrosion-resistant applications.
What makes the SSGM series different from other stainless worm gearboxes?
The SSGM series is distinguished by its six-sided fully machined 304 stainless steel body — every external face is precision machined rather than cast. This produces superior surface smoothness for washdown efficiency, flat reference surfaces for bracket integration, and show-quality aesthetics suitable for visible production areas like breweries, dairies, and pharmaceutical demonstration lines. Cast-body alternatives cannot match this surface-finish quality.
How many frame sizes does the SSGM series include?
The SSGM range comprises six frame sizes: SSGM-030, SSGM-040, SSGM-050, SSGM-063, SSGM-075, and SSGM-090. This is the widest frame-size range in our stainless worm gearbox catalogue, covering laboratory micro-drives through flagship heavy-duty petrochemical service. Every size shares the same machined-body engineering standard, 304 stainless construction, and 12-2 tin bronze worm gear specification.
How do I choose between the SSGM-050 and SSGM-063?
The SSGM-050 and SSGM-063 both feature a 25 mm output shaft but differ in center distance (50 mm vs 63 mm) and motor flange compatibility. The SSGM-050 accepts IEC 63B through 90B flanges — ideal for brewing, dairy, and mid-scale bottling. The SSGM-063 accepts 71B through 90B and offers higher torque capacity for marine, chemical dosing, and wastewater applications where corrosion resistance must meet mid-range power requirements.
Why choose machined 304 stainless over painted cast iron or aluminum?
Aluminum suffers galvanic corrosion in chloride and alkaline environments. Painted cast iron relies on a coating that chips and fails, exposing the iron to rapid oxidation. The machined 304 stainless steel used in the SSGM series provides inherent corrosion resistance throughout the housing and a superior surface finish from machining rather than casting. Over a 10-year horizon, lifecycle cost is significantly lower than repeated painting, rust remediation, or early replacement of aluminum alternatives.
What gear ratios are available across the SSGM range?
All six SSGM models support ratios from 7.5:1 to 100:1 with standard ratios of 7.5, 10, 15, 20, 25, 30, 40, 50, 60, 80, and 100. Specific ratio availability may vary with the selected IEC motor flange configuration. For applications requiring non-standard ratios or higher reduction, consult GBC engineering about double-reduction configurations combining SSGM with our SSVF reduction series.
Does GBC provide CAD files and technical drawings?
