Mechanical Power Transmission products for Mining Machinery

Flexible Gear Couplings

High performance and easy in installation manufactured using fully automatic hobbing machine.

Roller Chain Couplings

Roller Chain Flexible Couplings are compact, long lasting flexible couplings, capable of transmitting relatively high torques with minimum of space consumption

Torque Limiter

Nu-Teck torque limiter is a protective device that limits torque transmitted in a drive system by slipping when torque demand exceeds a preset value as a result of shock loads, over loads, or machine jams.

Sprockets

Nu-Teck Sprocket Wheels are manufactured from quality materials. Teeth are hob-cut for correct tooth form, tooth thickness and profile.

Mechanical Power Transmission Products for Mining Machinery Industry

In the Mining Machinery industry, power transmission components face the most demanding conditions of any sector — extreme shock loads from primary crushers, the massive continuous torque of SAG and ball mills, the safety-critical demands of mine winders and hoists, and the highly abrasive environment of ore, coal, and rock dust throughout the plant. Unplanned downtime in a mine or concentrator carries an exceptionally high cost per hour, making robust, maintainable drive components essential.

At Nu-Teck, we provide high-performance Gear, Disc, Tyre, and Jaw Couplings, along with Heavy-Duty Gear Pinions and Induction-Hardened Sprockets, engineered for the full range of surface and underground mining machinery — from primary crushers and SAG mills to mine winders, longwall equipment, and mineral processing plant.

Applications in the Mining Machinery Industry

Application-wise coupling reference across Crushing & Screening, Grinding & Milling, Hoisting & Shaft Sinking, Underground Mining, Slurry Handling, and Mineral Processing sections :

Application	Nu-Teck Coupling	Nu-Teck Advantage
Crushing & Screening
Jaw Crushers & Gyratory Crushers (Primary)	Gear Couplings (Heavy-Duty) & Gear Pinions	Handle the most severe shock loads in the plant from primary rock crushing — case-hardened pinions at 60 HRC resist the abrasive ore and rock dust environment while surviving the extreme cyclic torque spikes of the primary crushing cycle.
Cone Crushers & Impact Crushers (Secondary / Tertiary)	Gear Couplings (Spacer Type)	Spacer type allows eccentric or mantle maintenance without disturbing the drive motor — absorbs the continuous shock loads of secondary and tertiary crushing while accommodating the misalignment inherent in crusher drive arrangements.
Vibrating Screens & Grizzly Screens	Jaw Couplings	Jaw couplings dampen torsional vibration from eccentric screen drives — maintenance-free snap-wrap design withstands continuous vibration and abrasive dust, allowing elastomer replacement in minutes without dismantling the drive.
Grinding & Milling
SAG Mills & Ball Mills (Main Drive)	Gear Couplings (Heavy-Duty, Spacer Type) & Gear Pinions	The most torque-intensive drives in the concentrator — Nu-Teck heavy-duty gear pinions case-hardened to 60 HRC handle the massive continuous torque and cyclic load reversals of SAG and ball mill grinding, with spacer design enabling mill liner or pinion maintenance without motor removal.
Rod Mills & Pebble Mills	Gear Couplings (Spacer Type)	Transmit high torque at low speed for ore grinding — spacer design allows mill shell or girth gear maintenance without moving the drive motor, reducing planned shutdown duration at the critical grinding circuit.
Vertical Roller Mills & Stirred Media Mills	Gear Couplings & Disc Couplings	Disc couplings provide zero-backlash, torsionally rigid connection for high-speed stirred media mill drives — gear couplings on vertical roller mill main drives handle the high torque and axial load of the roller grinding mechanism.
Hoisting & Shaft Sinking
Mine Winders & Drum Hoists (Main Drive)	Gear Couplings (Heavy-Duty, Spacer Type) & Gear Pinions	Safety-critical drives for personnel and ore hoisting — Nu-Teck heavy-duty gear couplings and case-hardened pinions are engineered for the peak torque of loaded skip acceleration and the dynamic braking loads of controlled descent, with spacer type for drum or rope maintenance access.
Friction Hoists (Koepe Winders)	Gear Couplings Heavy-Duty)	Handle the high continuous torque and inertia loads of large Koepe winder drives — engineered for the safety-critical, high-cycle duty of deep mine hoisting with the reliability required for personnel transport applications.
Shaft Sinking Kibble & Cactus Grab Winches	Gear Couplings & Jaw Couplings	Gear couplings on main winch drives handle peak hoisting loads during shaft sinking — jaw couplings on auxiliary winch drives provide maintenance-free, reliable operation in the wet, confined environment of shaft sinking operations.
Underground Mining Equipment
Continuous Miners & Roadheaders	Gear Couplings (Heavy-Duty) & Gear Pinions	Handle extreme shock loads from cutter head impact with rock and coal faces — case-hardened gear pinions at 60 HRC resist the highly abrasive cutting environment and massive torque reversals of continuous miner cutter drum drives.
Longwall Shearers & Armoured Face Conveyors (AFC)	Gear Couplings (Heavy-Duty) & Sprockets	Drive shearer ranging arms and AFC chain conveyors in the confined longwall face environment — induction-hardened sprockets resist the highly abrasive coal and rock debris, with heavy-duty gear couplings handling the shock loads of shearer cutting cycles.
Underground Belt Conveyor Drives & Rope Haulage	Gear Couplings (Spacer Type) & Sprockets	Spacer gear couplings on underground belt conveyor drives allow drive pulley or gearbox maintenance without disturbing the motor in confined underground roadways — induction-hardened sprockets resist the abrasive coal dust environment.
Slurry Handling & Tailings
Slurry Pumps & Tailings Pumps	Gear Couplings (Spacer Type) & Tyre Couplings	Spacer gear couplings allow pump impeller or seal replacement without moving the motor — critical for minimising downtime on high-wear slurry pump drives handling abrasive ore pulp and tailings in the concentrator and tailings circuits.
Thickeners, Clarifiers & Agitator Drives	Gear Couplings (Spacer Type)	Transmit high torque at very low speed for thickener rake and agitator drives — spacer design allows rake arm or seal maintenance without disturbing the drive gearbox, handling the high static torque of raking settled mineral slurry.
Mineral Processing & Utilities
Flotation Cell Agitators & Conditioners	Jaw Couplings & Gear Couplings	Jaw couplings provide maintenance-free, vibration-damped operation for flotation cell agitator drives — gear couplings on larger conditioner drives handle the continuous high-torque demand of mineral conditioning in the flotation circuit.
Mine Dewatering, Compressed Air & Ventilation Fan Drives	Gear Couplings (Spacer Type) & Tyre Couplings	Spacer type allows fan rotor or pump impeller maintenance without disturbing the drive — critical for minimising downtime on mine dewatering and ventilation systems where continuous operation is a safety requirement.
