Enter your motor, mounting, ratio and output requirements. The selector checks them against the ZIPP GEAR planetary range and lists the gearboxes that fit, with the order code to quote.

Start from a motor

Standard mounting interface Fills the pilot and bolt circle from the catalog. Add your motor's torque and speed below.

Motor

Rated torque (Nm) Continuous torque from the motor datasheet. Peak torque (Nm) Checked against the gearbox maximum output torque. Rated speed (rpm) Checked against the gearbox input speed. Power (kW) Used with speed if you have no torque figure.

Motor mounting

Shaft diameter (mm) Pilot diameter (mm) The centring spigot on the motor flange. Bolt circle diameter (mm) Flange size, square (mm) Side of the motor flange.

Ratio

Gear ratio Catalog ratios: 1 to 20 single stage, 12 to 140 two stage. Ratio tolerance Catalog ratios are fixed steps.

Output requirements

Output torque needed (Nm) Use instead of, or on top of, the motor figures. Peak output torque (Nm) Output shaft diameter (mm) Output flange size (mm) Square side or round diameter. Output flange shape Radial load (N) Checked against the catalog maximum. Axial load (N) Max backlash (arcmin) Leave blank for standard.

Covers the planetary gearboxes PS / PN, ZPS / ZPN, ZS / ZN / ZE / ZF and the right-angle gearboxes RB / RL, ZSR, ZFR, ZRPS / ZRPN, ZAR. Other ZIPP GEAR series are selected by an engineer: send your requirements.
