3-speed Crank Axle Gear box 

The positions of the gears in this gear box can be altered to operate in 3 different gear ratios: 16:1, 58:1 and 203:1. Gear casing and gears are precisely modeled from plastic. Metal crank arms can be attached to the end of the output shaft.

4-speed Crank Axle Gear box 

By altering the combinations of the gears, 4 different gear ratios can be obtained: 126:1, 441:1, 1534:1, 5402:1. These low outputs speeds are best when a high torque is required as opposed to speed.

6-speed Crank Axle Gearbox 

By altering the combinations of the gears, 6 different gear ratios can be obtained: 11.6:1, 29.8:1, 76.5:1, 196.7:1, 505.9:1 and 1300.9:1. Comes with RE-260 electric motor and 3 types of crank arms for multiple applications.

High power gear box H.E. (High efficiency) 

This gear box is designed for high torque output rather than speed and is suitable for constructing models such as tanks, buggies, tracked vehicles etc. The gear box has 2 ratios: 41.7:1 and 64.8:1.

High speed gear box H.E. (High efficiency) 

This is a versatile and easy-to-construct gear box. The gears are made of polyacetal resin which permit efficient power transmission with less mechanical noise than metal gears. 2 gear ratios, 11.6:1 and 18.1:1 can be selected.

Planetary Gear Box set 

The planetary gear box set is a highly versatile system for reduction of high RPM electric motors high torque low RPM applications. The adoptions of these units is limited only to your imagination!

Twin motor gear box 

This is a ready to assemble gear box that uses two motors to independently control each of the output's shafts. The gears and gear case are accurately molded from tough plastic for smooth and efficient operation. 2 gear ratios, 207:1 and 58;1 can be selected.

Universal Gear Box

An extremely useful device that can power a hexagonal shaft in a horizontal or vertical position relative to the motor. Various arrangements of 24T and 26T plastic gears produces 3 speed options.

Worm gear box H.E. (High efficiency)

The worm gear can produce extremely low speeds of rotation and is used for gear reduction. The 2 selectable gear ratios are: 216.1:1 and 336.1:1. It allows versatile applications for your projects.

Ball Caster set (2pcs.)

These ball casters can be mounted on the front or back of mechanical devices to act as a third wheel. Includes 2 ball casters, 2 3-legged supports (25mm and 35mm) and all necessary screws and attachment pieces.

Truck Tire set
