Sier-Bath Nylon couplings are compact and require no lubrication. They operate above a broad temperature range at speeds up to 5,000 RPM and therefore are properly 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, eliminating the want for seals. The resilient nature of the nylon materials tends to make the make contact with on the hubs and sleeves just about frictionless. Considering that no lubrication is used, the coupling can readily be adapted to a lot of applications including vertical and blind installations wherever the slip-together parts offer you quick inspection and adjustment.
Operationally, the coupling provides a minimal backlash alternative that will 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 influence balance or safety. The nylon sleeve permits misalignment as much as 5° for Dentex and Nyflex couplings and 3° for the Mite.
When entirely assembled, the Mite coupling weighs significantly less than 1lb and also the Nyflex only three.50 lbs. 2 Spirolox Retaining Rings
Sleeve is securely held within the hubs by these spring-steel retaining rings. They might be eliminated in seconds, still they’ll stand up to five,000 lbs endthrust.
Nylon Sleeve
Resilient, light-weight, abrasion and corrosion resistant nylon is accurately molded to mesh precisely with hubs. Their just about frictionless properties get rid of the require for lubrication.
2 Hubs
Sintered iron is normal while in the Nyflex and Mite. Teeth are crowned to supply greater misalignment capacity and to avert gouging of Nylon sleeve. Sustain 0.13 inch spacing between hubs.
