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.
