Nl Nylon Inner Gear Ring Gear Coupling Hydraulic Quick Coupling for Pump

NL coupling is a type of nylon internal gear coupling with multiple advantages and wide applications.
NL coupling is a nylon internal gear coupling with precise design, simple structure, easy disassembly and assembly, convenient operation, easy maintenance, long service life, low noise, low cost, and small transmission power loss. This type of coupling allows for significant axial, radial, and angular displacement, making it suitable for flexible transmission between shafts. Its shaft hole types include cylindrical (Y), conical (Z), and short cylindrical (J), and the shaft hole and keyway are processed according to the national standard GB3852-83 "Coupling Shaft Hole and Keyway Form and Size". The working temperature range of NL couplings is -20 ºC to+70 ºC, suitable for various industrial fields such as forging, construction, mining, plastics, food, engineering, petroleum, chemical, machine tools, ships, leather, textile, fan, water pump and other industries of transmission machinery.
In terms of materials, the NL coupling is made of cast iron HT20-40 precision casting and reinforced injection molded nylon (nylon 66) and other materials, which have undergone special processing to ensure the performance and durability of the product. In addition, the elastic sleeve of NL coupling can be made of various hardness synthetic nylon, cast nylon elastomer and other materials according to the user's requirements to meet different working conditions and needs.
Overall, NL couplings are widely used in the industrial field due to their advantages of simple structure, easy maintenance, easy disassembly and assembly, low noise, minimal loss of transmission efficiency, and long service life. They have become an ideal choice for many equipment and mechanical transmissions
