Parallel Shaft Gearmotors & Speed Reducers

WATT Drive Parallel Shaft Gearmotors & Speed Reducers are available in two styles. The A series is a shaft mount with torque arm or buffer kit. The F series can be base mounted.

Aluminum Body Worm Speed Reducers

Varvel worm gear speed reducers and gearboxes provide highly reliable operation in a light weight but very strong die cast aluminum housing. Ground worms offer better efficiency and long life. Many other features and options are available to satisfy unique needs.

Aluminum Body Inline Helical Speed Reducers

Varvel economy aluminum body helical speed reducer provides highly reliable power transmission for general purpose applications. These gearboxes offer cost effective operation and superior performance over similar products.

Spiral Bevel Gearboxes

Right Angle Gearboxes – Series STD

Tandler® spiral bevel gearboxes feature low backlash and low transmission error. The program also offers the widest range of sizes, ratios, shaft configurations, and special options available.

Hollow Shaft Gearboxes – Series HW

Tandler® hollow shaft gearboxes offer shaft mount designs with keyways, square splines, involute splines, or smooth bores with shrink disks.

Right Angle Reversing/Declutching Gearboxes – Series S/AS

Tandler® reversing or disengaging gearboxes are used to declutch a drive element or reverse rotational direction in a right angle configuration. Actuation can be achieved manually or with pneumatics.

Reinforced Shaft Gearboxes – Series WV

A bevel gearbox with reinforced shaft is commonly used in line-shaft drive applications where only a proportion of the full torque is taken off the main drive shaft at various intervals.

Two Way Auxiliary Gearboxes – Series EA

Tandler® auxiliary gearboxes offer up to 4 shaft extensions in the same plane. Some versions are available with hollow shafts and mounting flanges.

High Torque Density – Power Master

A different internal design offers higher torque density and more robust design for demanding industrial applications.

Stainless Steel Gearboxes – Series VA

The VA series is a complete stainless steel design for high performance or precise motion control requirements.

Shaft Phasing & Variable Speed Gearboxes

Right Angle Phasing Gearboxes – Series SP2

The Tandler® Series SP2 right angle speed correction gearbox provides low backlash and low transmission error for applications requiring shaft phasing, timing, positioning, registration control, tension control, and narrow range speed control.

Double Planetary Inline Phasing Gearboxes – Series PD2

The Tandler® series PD2 double planetary speed correction gearbox is available in an inline 1:1 ratio and is used for shaft phasing, registration, and narrow range speed control.

Single Planetary Inline Phasing Gearboxes – Series PE2

The Tandler® series PE2 single planetary speed correction gearbox is available in an inline 3:1 ratio and is used for shaft phasing, registration, and narrow range speed control.

Mechanical Variable Speed Drives
