SPH Series The SPH is GAM’s latest solution for today’s demanding motion control challenges. It is available in six frame sizes with torque ratings ranging from 15 to 900Nm. The SPH features precision cut helical gears which means high torque capacity relative to the frame size as well as smooth and quiet torque transmission. With several output configurations available, machine integration is simplified.

SPL Series The SPL is the next generation of our I.M.P.A.C.T.® series. It has been designed with the latest servo motors and your most demanding motion control applications in mind. The SPL can handle oversized motor shafts, higher input speeds, and high torques. Now the SPL has been expanded to incorporate our unique Integrated Modular Planetary and Coupling Technology (I.M.P.A.C.T.®). Our planetary and coupling package increases system stiffness and reduces the overall costs of conventional packages.

Dyna Series The Dyna Series is our highest precision right-angle gear reducer utilizing sophisticated hypoid gearing. The benefit of hypoid gearing is that it combines the space and configuration advantages of worm gearing with the high efficiencies of bevel gearing. The result is that the Dyna Series is able to achieve ratios up to 15:1 in a single stage and ratios up to 100:1 in 2 stages.

For the most demanding motion control applications that require high angular accuracy, choose our new DSX model. It offers extremely low backlash, extremely smooth torque transmission and extremely low noise. Angular accuracy test data is available upon request.

We’ve taken the highest-performing gearbox on the market and made some design modifications to further distance it from other gearboxes. The housing and construction have been enhanced and now offer even greater durability. Gear rotation is smoother, bearing life improved and noise is reduced.

EPL Series Our EPL Series is widely known as the best value on the market for inline planetary gear reducers. That’s because it offers the best quality available for the price point. We’ve added some features that make it an even better value and unequaled in its class and ideal for most servo applications.

SSP Series Our new SSP Series is an innovative washdown servo gearbox solution designed for food, medical or sanitary applications. It is a precision planetary gearbox outwardly constructed of 300-series stainless steel. The motor adapter plate, housing and shaft are all stainless steel. Viton® seals, stainless steel hardware and sealed interfaces provide outstanding corrosion resistance in all types of wet and caustic washdown environments. Ideal for any light or demanding servo application where corrosion resistance is a requirement, the SSP Series offers economy, high precision, and long lasting performance.

Dyna Lite Series Now there’s a right-angle gearbox that has the performance and price point of a precision inline gearbox. Our redesigned Dyna-Lite Series use hypoid gearing that combines the space and configuration advantages of worm gearing with the high efficiency of bevel gearing. It is drop-in replacement for many right-angle and in-line planetary gear reducers.

FP Series The F-Series is a “shaftless” planetary gearbox that offers advantages in space and performance. The output flange allows machine elements such as pinion gears, pulleys, rotary index tables, and transmission shafting to be easily connected directly to the output. The design also provides high torsional and tilting rigidity that improves machine performance.

PE SERIES GAM introduces the PE Series as its lowest cost planetary gearbox line. The PE Series is a great value for servo, stepper, and other applications. It offers the best quality available for the price point. The PE Series has features that make it unequaled in its class and ideal for many applications.

VC SERIES Our VC Series is a great spiral bevel gearbox solution. These robust gearboxes feature many output configurations and include the integrated motor mounts. Single, multiple shaft or hollow shaft configurations are available. 1:1 up to 6:1 ratios are available.

LL Series (Mini Spiral Bevel Gearboxes)
Small, lightweight, and powerful.

Our LL Series is a great miniature spiral bevel gearbox solution for servo applications. These robust gearboxes feature many output configurations and include integrated motor mounts. Single, multiple shaft or hollow shaft configurations are available. 1:1 up to 4:1 ratios are available.

Offered in two compact frame sizes (35mm and 45mm), the housings are constructed of high strength aluminum which makes them lightweight and dissipate heat efficiently. They are then hard coat anodized for corrosion resistance. Numerous shaft configurations with Viton / FPM seals make them an excellent choice for semi-conductor, pharmaceutical, medical, or other mechatronic applications where small size and high performance matter.

GAM offers you a complete line of elastomer couplings. We can help you define your coupling needs and offer you technically superior and cost-effective solutions. Our extensive manufacturing capabilities and highly skilled machinists enable us to customize your couplings for your exact applications and we offer same day delivery for custom bored couplings.

• The use of elastomer spiders with shore hardness ratings from 72-D to 98-A permit dampening of vibration caused by system resonance
• An affordable alternative if high stiffness is not critical
• The involute shaped teeth of the elastomer spider and jaws are preloaded and will not loosen over time.
• Ensures zero backlash and allows for easy plug-in assembly

Safety couplings are used to minimize expensive damage when a collision occurs in a high performance servo drive system. When a collision occurs, the safety coupling will stop the destructive inertial forces instantly and eliminate downtime and repair costs often associated when just an overload relay is used.

Distance couplings can span axial lengths of 20ft without the need for additional intermediate bearings. They are precision machined to the required length and are balanced for high speeds. Their special designs allow for simple installation which make “one person assembly” possible. Even at these long distances, they remain zero backlash, torsionally stiff, and compensate for shaft mis-alignments to prevent premature bearing failures.

Our no-hassle solution for mounting linear slides to motors and gearboxes is our LSK (Linear Slide Kit.) It can be customized to any motor or gearbox and linear slide. A coupling is included – bellows or elastomer. The LSK is readily available and comes complete with mounting hardware. You just need to tighten the bolts.

• Customized assembly to mount any motor or gearbox to any linear slide
• Coupling included
• Quick delivery (Most designs ship in about one week)

The EPL-H Series was designed specifically to address the difficulty of connecting gear reducers to linear products. The hollow output and zero backlash clamping ring create the quickest and most economical way to add gearing to essentially any linear belt or ball screw.
