Frequently Asked Questions
QWhat materials are used for the main load-bearing components of the KH series?
The housing and bracket cap are constructed from high-strength Alloy Steel or Carbon Steel. The worm gear is made of durable Nodular Cast Iron, and the worm shaft is made of chrome-plated Carbon Steel to ensure long service life and high wear resistance.
QWhat is the maximum output torque capacity within this gear operator series?
The series offers a wide performance range, starting from 280 N.M output torque with the compact KH-1 model, up to a maximum of 5,500 N.M output torque with the heavy-duty KH-8 model.
QWhich parts of the KH gear operator are made of stainless steel?
To prevent rust and facilitate adjustments, the adjustable bolts, nuts, and standard assembly bolts are manufactured using high-quality Stainless Steel.
QHow does the speed ratio scale across the different models?
The speed ratios are designed to match the torque capacity of each model, scaling from 26:1 on the smallest KH-1 unit up to 100:1 on the largest KH-8 unit for optimal mechanical advantage.
QWhat is the weight range of these worm gear units?
The weight varies significantly depending on the model capacity. The lightest operator (KH-1) weighs approximately 2.6 kg, while the largest, heavy-duty industrial operator (KH-8) weighs 115 kg.
