Helical Gearbox

What are gears and gearboxes? A gear is a rotating machine part featuring cut teeth or cogs, which is meant to mesh with another toothed part to be able to transmit torque. In a layman’s language, gears are probably the most crucial parts of any motors and machine...

screw jack

Instead of the worm drive systems discussed here, a bevel gear system could be used to convert rotation to linear movement. This would offer greater effectiveness to a machine screw jack due to it producing a rolling contact instead of the sliding contact of worm...

spiral gear

Spiral bevel gears are usually made from hardened steel. One's teeth of these gears are often ground for a far more precise finish allowing for little noise at high speeds. You can specify left hand or right hand depending on the direction you have to run the gearsIf...

servo motor and gearbox

Whenever a conventional planetary gearhead is mounted to a engine, the sun gear must be aligned to compensate for runout error of the servomotor shaft. Without proper alignment, load is definitely unevenly distributed over the planetary gears and the drive train...

Sier-Bath Gear Type Couplings

High Performance Gear Couplings

Rigid Compression Couplings

  • For hard applications where strength and affordability are essential, the steel design of rigid compression couplings is suitable
    EP cast steel couplings are a great choice for joining two shafts of the same size
    This kind of coupling is also called a “rigid clamp style” coupling.

Motion Control Couplings

  • HP and RPM of the driver
    Shaft size of the driver and driven
    Application requirements
    Environmental conditions ( i. e. extreme heat, corrosive conditions, space limitations )
    Space Limitations ( i. e. maximum outside diameter and overall length for the coupling)
