NL Type Nylon Tooth Gear Flexible Coupling
Product Overview
NL Type Nylon Tooth Gear Flexible Coupling is a high‑performance transmission connecting component, widely used in industrial hydraulic system, Power Pack Unit and mechanical driving Machine. It connects motor shaft and hydraulic pump shaft, transmits torque while compensating minor radial, angular and axial misalignment between two shafts.
This coupling adopts metal hub matched with high‑strength nylon tooth sleeve. The nylon gear sleeve delivers good shock absorption and noise reduction performance. It can buffer vibration generated during operation of the Power Pack Unit, protect pump and motor parts inside the hydraulic system, and reduce mechanical wear and failure risk of the whole Machine.

Working Principle
Installed between driving motor and hydraulic pump of the hydraulic system, the NL‑type coupling transfers rotational torque through meshing of metal hub teeth and nylon tooth sleeve. The elastic nylon sleeve absorbs vibration and impact load from running Power Pack Unit. It offsets small installation misalignment, avoids direct rigid stress on pump and motor shafts, and keeps stable operation of the Machine.
The nylon tooth sleeve acts as a vulnerable wearing part. When heavy overload occurs, the nylon sleeve will wear or fail first, which can protect the expensive pump and motor components in the hydraulic system from damage. Users only need to replace the nylon sleeve instead of changing the whole coupling to resume working of the Power Pack Unit.
Core Advantages
1. Nylon tooth sleeve provides excellent shock absorption and noise reduction, effectively dampens vibration of Power Pack Unit, safeguards the hydraulic system and host Machine.
2. Compensates small radial, angular and axial shaft misalignment, lowers installation precision requirements.
3. Protective failure mode: nylon sleeve will wear under overload, avoids damaging hydraulic pump and motor of the hydraulic system.
4. Easy disassembly and maintenance, only replace nylon sleeve, cut down maintenance cost and downtime of the Machine.
5. Complete size series, suitable for new assembly or retrofitting of various Power Pack Unit and hydraulic‑driven Machine.
Application Range
NL Type Nylon Tooth Gear Flexible Coupling is widely applied to the hydraulic system of hydraulic Power Pack Unit, injection molding machines, hydraulic presses, machine tools and other hydraulic‑driven Machine. It is popular among hydraulic equipment manufacturers, maintenance workshops and global spare‑parts distributors.
