Sier-Bath Nylon couplings are compact and require no lubrication. They operate over a broad temperature range at speeds as much as five,000 RPM and are successfully utilized in applications this kind of as Motor/Generator sets, pump sets, and lots of light to medium duty industrial coupling applications.
No lubricants are ever necessary, getting rid of the want for seals. The resilient nature on the nylon materials helps make the get hold of on the hubs and sleeves just about frictionless. Because no lubrication is made use of, the coupling can readily be adapted to lots of applications which include vertical and blind installations where the slip-together components offer you quick inspection and adjustment.
Operationally, the coupling offers a minimal backlash remedy that could operate in ambient temperature environments from -40° to 150° F. Nylon Sleeve couplings have precision molded sleeves and hubs without bolts, pins, flanges, or protrusions to affect balance or safety. The nylon sleeve permits misalignment as much as 5° for Dentex and Nyflex couplings and 3° for that Mite.
When absolutely assembled, the Mite coupling weighs less than 1lb along with the Nyflex only three.50 lbs. 2 Spirolox Retaining Rings
Sleeve is securely held to the hubs by these spring-steel retaining rings. They could be removed in seconds, yet they’ll withstand 5,000 lbs endthrust.
Nylon Sleeve
Resilient, lightweight, abrasion and corrosion resistant nylon is accurately molded to mesh precisely with hubs. Their pretty much frictionless properties reduce the have to have for lubrication.
two Hubs
Sintered iron is typical from the Nyflex and Mite. Teeth are crowned to provide greater misalignment capacity and to avert gouging of Nylon sleeve. Retain 0.13 inch spacing involving hubs.
