MengziNUP New Elastic Sleeve Pin Coupling

The NUP flexible coupling’s elastomer material is made of polyurethane reinforced with graphite, offering excellent toughness, self-lubrication, and wear resistance. It features a hollow-grid design and comes in three different elasticity options, providing superior vibration absorption and impact resistance. The conical-bore bolts ensure a tight fit that remains secure and does not loosen over time. Thanks to its high safety and reliability, as well as its outstanding vibration absorption and impact resistance, this coupling has received unanimous praise from more than 100 users. As a result, it has been awarded innovation funds by the Ministry of Science and Technology of China, the Provincial Department of Science and Technology, and the Municipal Science and Technology Commission.

Product Description

Product Features
The NUP elastic sleeve material is made of polyurethane reinforced with graphite, offering excellent toughness, self-lubrication, and wear resistance. It features a hollow grid design and comes in three different elasticity options, providing vibration absorption and impact resistance. The tapered-hole bolts ensure a tight fit that prevents loosening.
Thanks to its high safety and reliability, as well as its outstanding vibration absorption and shock resistance capabilities, this coupling has received unanimous praise from over 100 users and has been awarded innovation funds by the Ministry of Science and Technology, the Provincial Department of Science and Technology, and the Municipal Science and Technology Commission.
 
Application scenarios
Torque is transmitted through elastic buffering, so the coupling typically exhibits flexible rubber-like properties. It is suitable for pumps, blower units, variable-frequency drive units, diesel engine sets, piston compressor units, and any rotating machinery subjected to impact loads, effectively addressing the challenge of high-frequency torsional oscillations in their transmission systems.
Its structural configuration is shown in Figure 3.1, and the technical parameters and main dimensions are listed in Table 3-1.
