Complete Corrosion-Resistant Drive Family
The GBC SSVF Stainless Steel Worm Gearbox Series delivers three precision-cast 304 stainless steel frame sizes for demanding washdown and corrosive applications. Every unit features a VF-standard footprint, an electrolytically polished housing, a 12-2 tin bronze worm gear, and fully synthetic worm gear oil. Browse the complete worm reducer gearbox category for all drive technology options GBC offers across Australia.
Engineered for Corrosion
Solid 304 stainless housing and electrolytically polished surface resist saltwater pitting, chemical attack, and daily high-pressure washdowns without coating failure.
Sized for Every Duty
Output shafts from 18 mm to 25 mm cover light packaging drives up to medium-heavy duty offshore and petrochemical installations with a single compatible platform.
Direct VF Replacement
Identical mounting geometry to standard VF cast iron units. Swap out failing gearboxes one-for-one with zero mechanical redesign or baseplate modification.

Why Engineers Specify the SSVF Series
Every SSVF unit shares the same engineering standards and material specifications. These six characteristics define the difference between the SSVF series and conventional cast iron or aluminum worm reducers.
304 Stainless Precision Casting
Housing, wheel core, and output shaft are all manufactured from 304 stainless steel. No painted surfaces to chip, no aluminum to corrode.
Electrolytically Polished Surface
A mirror-smooth finish prevents bacterial adhesion, simplifies washdown cleaning, and resists pitting from chlorides and chemical vapors.
12-2 Tin Bronze Worm Gear
Bronze worm gear delivers quiet operation, low friction, excellent wear resistance, and natural corrosion compatibility with the stainless housing.
Fully Synthetic Worm Gear Oil
Factory-filled synthetic lubricant provides superior thermal stability, reduced internal friction, and extended oil-change intervals.
VF Dimensional Compatibility
Drop-in replacement of corroding cast iron or aluminum VF units without bracket modifications or coupling changes.
Multi-Directional Mounting
Every SSVF size supports horizontal, vertical, and inverted orientations, providing installation flexibility for retrofit projects.

Frequently Asked Questions
Common questions engineers and procurement professionals ask when specifying SSVF stainless steel worm gearboxes for corrosive-environment applications.
What is the SSVF stainless steel worm gearbox series?
The SSVF series is a family of three frame sizes (SSVF-040, 050, 063) of stainless steel worm gear reducers built from precision-cast 304 stainless steel with an electrolytically polished surface finish. Every unit uses a 12-2 tin bronze worm gear and fully synthetic worm gear oil.
Are SSVF reducers dimensionally interchangeable with VF gearboxes?
Yes. Every SSVF model is dimensionally identical to its VF counterpart. Mounting patterns, output shaft dimensions, flange patterns, and bolt-hole spacing are identical, allowing direct one-for-one replacement of corroded cast iron or aluminum units.
How do I choose between the SSVF-050 and SSVF-063?
Both models feature a 25 mm output shaft. The SSVF-050 accepts IEC motor flanges 63B to 80B, suitable for dairy and medium-duty applications. The SSVF-063 accepts 71B to 90B and offers a larger center distance (63 mm) engineered for heavier loads including chemical dosing and marine conveyors.
Why stainless steel instead of aluminum or painted cast iron?
Aluminum suffers galvanic corrosion in alkaline environments. Painted cast iron relies on a coating that chips and fails. The 304 stainless steel used in the SSVF series provides inherent corrosion resistance throughout, eliminating coating maintenance and premature replacement.
What gear ratios are available across the SSVF range?
All three SSVF 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.
Does GBC provide CAD files and technical drawings?
Yes. 2D dimensional drawings and 3D CAD files are available free of charge for every SSVF model. Contact the GBC engineering team via our contact page with your preferred format.
