Trapezoidal Vs. ACME

Please note that while Trapezoidal and ACME threads are similar there are some subtle differences and the nuts are not interchangeable. Trapezoidal is the metric standard to DIN 103, has a pitch angle of 30 degrees while ACME has 29 degrees and the diameter and pitch is measured in inches. While we stock Trapezoidal, ACME is available on request.

Spiral Bevel Gearboxes Types DZ & ZP
1:1, 2:1, 3:1
Shaft sizes 8mm - 35mm
Single or double output
Most sizes stocked
DZ and ZP Spiral Bevel Gearboxes are designed for industrial applications where rotary power must be transferred between two shafts at right angles to each other.

Housing - single piece aluminium alloy
Gears are cut on Gleason Hobbing machine to ensure maximum load capacity.  Nickel chrome steel gears with surface case hardened teeth for maximum service life, while leaving the tooth core tough and flexible to resisit mechanical shocks.
Units are manufactured with backlash tolerances to ensure perfect gear engagement and quiet operation.
Oil seals are fitted to all models.  High and low temperature special seals are available.

Selecting the correct type of gearbox is not simply a question of defining the power required in relation to rpm and the torque to be transmitted.   It also involves defining the conditions under which the gearbox will be used.
