Sier-Bath Nylon couplings are compact and need no lubrication. They operate over a wide temperature assortment at speeds up to 5,000 RPM and are properly used in applications this kind of as Motor/Generator sets, pump sets, and many light to medium duty industrial coupling applications.
No lubricants are ever expected, getting rid of the need to have for seals. The resilient nature with the nylon material tends to make the get hold of on the hubs and sleeves just about frictionless. Because no lubrication is used, the coupling can readily be adapted to quite a few applications which include vertical and blind installations exactly where the slip-together parts give easy inspection and adjustment.
Operationally, the coupling provides a minimum backlash resolution that may operate in ambient temperature environments from -40° to 150° F. Nylon Sleeve couplings have precision molded sleeves and hubs without any bolts, pins, flanges, or protrusions to influence balance or safety. The nylon sleeve permits misalignment up to 5° for Dentex and Nyflex couplings and 3° for that Mite.
When totally assembled, the Mite coupling weighs less than 1lb along with the Nyflex only three.50 lbs. two Spirolox Retaining Rings
Sleeve is securely held within the hubs by these spring-steel retaining rings. They might be removed in seconds, yet they’ll stand up to 5,000 lbs endthrust.
Nylon Sleeve
Resilient, lightweight, abrasion and corrosion resistant nylon is accurately molded to mesh exactly with hubs. Their virtually frictionless properties remove the will need for lubrication.
two Hubs
Sintered iron is normal while in the Nyflex Sier Bath%20Nylon%20couplingsand Mite. Teeth are crowned to provide greater misalignment capability and also to prevent gouging of Nylon sleeve. Keep 0.13 inch spacing concerning hubs.
