Mechanical Power Transmission products for Paper MIlls

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 Paper MIlls

In the Paper Mills industry, power transmission components must deliver precise speed synchronization across multi-section paper machines running at speeds exceeding 1500 m/min, while simultaneously surviving the high-humidity, chemically aggressive, and thermally demanding environment of the mill. A single coupling failure or speed variation event can cause a costly sheet break, unplanned shutdown, or quality rejection across an entire production run.

At Nu-Teck, we provide high-performance Gear, Disc, Tyre, and Jaw Couplings, along with Heavy-Duty Gear Pinions and Precision Sprockets, engineered to keep every section of your paper machine and pulp mill running at peak efficiency.

Applications in the Paper Mills Industry

Application-wise coupling reference across Wood Preparation, Stock Preparation, Wet End, Dryer Section, Calendering, Converting, and Utility sections of the paper mill :

Application	Nu-Teck Coupling	Nu-Teck Advantage
Wood Preparation & Pulping Section
Wood Chippers & Debarkers	Gear Couplings (Heavy-Duty) & Gear Pinions	Handle massive shock loads from log and chip processing — case-hardened pinions at 60 HRC resist the highly abrasive wood fibre environment and extreme cyclic torque spikes of the chipping cycle.
Pulp Digesters & Refiner Drives	Gear Couplings ( Spacer / Ext. DBSE)	Spacer design allows refiner plate or seal maintenance without moving the motor — critical for minimising downtime in continuous pulping operations where refiner gap consistency directly affects pulp quality.
Pulp Pumps & Chest Agitators	Tyre / Jaw Couplings	Tyre couplings absorb high misalignment and vibration in pulp pump drives subject to pipe thermal growth — easy elastomer replacement without disturbing pipework in wet, confined pulp chest areas.
Stock Preparation & Approach Flow
Disc Refiners & Conical Refiners	Gear Couplings (Heavy-Duty, Spacer Type)	Transmit very high torque for fibre beating and refining — spacer type allows refiner disc replacement without disturbing the motor, ensuring precise freeness control for target paper grades.
Screens, Cleaners & Fan Pumps	Jaw Couplings & Disc Couplings	Zero-backlash disc couplings on high-speed fan pumps ensure precise flow control to the headbox — jaw couplings on screen drives provide maintenance-free, vibration-damped operation in wet stock areas.
Broke Pulper & Repulper Drives	Jaw Couplings	Maintenance-free jaw couplings drive broke pulper agitators handling wet trim and reject sheets — snap-wrap elastomer replacement in minutes without moving the motor in congested wet-end areas.
Paper Machine — Wet End
Wire / Forming Section Drive (Table Rolls & Foils)	Disc Couplings (Zero-Backlash)	Zero-backlash disc couplings synchronize the wire section drive rolls with absolute precision — eliminating speed variation that causes wire marking or sheet breaks at the critical sheet formation zone.
Press Section Rolls Drive	Gear Couplings (Spacer Type) & Disc Couplings	Spacer gear couplings handle the high torque of press roll nip drives while accommodating roll crown and deflection misalignment — disc couplings on felt rolls provide zero-backlash speed synchronization.
Suction Roll & Couch Roll Drive	Gear Couplings (Spacer Type)	Spacer design allows suction roll sleeve removal for re-drilling or replacement without disturbing the drive — significantly reducing planned maintenance downtime at the critical wet-end dewatering section.
Paper Machine — Dryer Section
Dryer Section — Dryer Can Drives	Gear Couplings & Heavy-Duty Gear Pinions	Drive multiple steam-heated dryer cans through precision gear pinions — case-hardened to 60 HRC for the high-temperature, high-humidity dryer section environment, ensuring smooth torque transmission across all dryer groups.
Dryer Section — Draw / Section Drives	Disc Couplings (Zero-Backlash)	Zero-backlash disc couplings maintain precise draw (speed differential) between dryer groups — eliminating sheet tension variation that causes sheet breaks, critical for high-speed fine paper and board machines.
Calendering, Reeling & Converting
Soft Calender & Supercalender Drives	Disc Couplings (Zero-Backlash)	Precise speed synchronization across calender nip rolls — zero-backlash disc couplings eliminate speed variation that causes caliper variation or surface defects in finished paper grades.
Pope Reel / Winder Drive	Gear Couplings (Spacer Type)	Spacer type allows reel spool or drum maintenance without disturbing the drive — handling the high inertia loads of full-reel acceleration and deceleration during reel transfer cycles.
Slitter-Rewinder & Sheeter Drives	Jaw Couplings & Precision Sprockets	Maintenance-free jaw couplings drive slitter and sheeter roll feeds — snap-wrap elastomer replacement in minutes without dismantling the drive in the congested converting section.
Utilities & Chemical Recovery
Black Liquor & Recovery Boiler Pumps	Tyre / Jaw Couplings	Tyre couplings handle high misalignment in recovery boiler feed and black liquor pump drives — corrosion-resistant construction withstands the aggressive chemical environment of the chemical recovery section.
Vacuum Pumps & Compressors	Jaw / Disc Couplings	Disc couplings on high-speed vacuum pump drives provide torsional rigidity for stable vacuum levels — jaw couplings on compressor auxiliary drives offer maintenance-free operation in utility areas.

Nu-Teck Customised Products for Paper Mills Industry

Nu-Teck's specialised products are engineered to meet the precision synchronization, high-humidity, chemical resistance, and continuous high-torque challenges unique to pulp and paper manufacturing :

Coupling / Product Type	Description & Nu-Teck Advantage
