EP Gear’s 800 Series contains a focused collection of compact, durable helical gear drives that offer long-existence performance and simplified maintenance. A broad range of reduction ratios suit an even broader selection of specifications, while a variety of input shaft configurations maximize flexibility. In addition, the number of products that complement this series of gear drives make it a perfect choice for today’s industrial distributor.
The 800 Series offers a functional interchange for ep and other European producers’ helical gear drives,rendering it uniquely practical for replacement applications.
Four basic sizes 1/6 – 10 HP
Over 40 different ratios 1.5:1 – 71:1 double-reduction ratios 36:1 – 250:1 triple-reduction ratios
Non-flanged and NEMA c-face input styles
Base-mount and result flange-mount models available
Output-shaft diameters from 3/4″ to at least one 1 5/8″
The standard NEMA C-face design encourage any standard NEMA electric motor, making it exceptionally versatile.
Ratios up to 70:1 in just two stages means increased performance and reduced case size.
Accessible oil seals simplify regimen product maintenance.
All units can be double sealed on both the input and output to withstand the rigors of even the most demanding applications.
800 Series drives come pre-filled with synthetic lubrication for your specific mounting position.
Sizes 3 and 4 are lubricated forever which promotes trouble-free operation.
Washdown duty devices in white or stainless epoxy coatings make these equipment drives ideal for the most severe Washdown.
Correct angle bevel speed reducers decrease speed and increase torque from the driver end to the driven end in a drive system. They have got a beveled gear that allows the reducer to rotate in both directions and operate with low noise and vibration. They are usually crafted from durable, corrosion-resistant materials like stainless steel.
Wide range of accessories and non-standard designs
Single piece housing with high structural stiffness
Easy and functional shaft-mounting design
Minimum maintenance requirements
High, reliable and tested performance
Ideal for the heaviest duties

The exclusive usage of the involute helicoid thread form on the worm and gear offers high efficiencies and lengthy service lifestyle on draglines and shovels. The hardened,surface and polished alloy metal worm develops a soft, work hardened surface on the bronze equipment. For this reason, the worm gears put on in and improve with prolonged service while additional gears are deteriorating.
