Overview

Lovejoy / Sier-Bath Nyflex

®

and Mite

® Nylon Sleeve Resilient, lightweight, abrasion and corrosion resistant nylon is accurately molded to mesh precisely with hubs. Their almost frictionless properties eliminate the need for lubrication. Lovejoy / Sier-Bath Nylon couplings are compact and require no lubrication. They operate over a wide temperature range at speeds up to 5,000 RPM and are effectively used in applications such as Motor/ Generator sets, pump sets, and many light to medium duty industrial coupling applications.No lubricants are ever required, eliminating the need for seals. The resilient nature of the nylon material makes the contact of the hubs and sleeves almost frictionless. Since no lubrication is used, the coupling can readily be adapted to many applications including vertical and blind installations where the slip-together components offer easy inspection and adjustment.Operationally, the coupling offers a minimum backlash solution that will operate in ambient temperature environments from -40° to 150° F. Nylon Sleeve couplings have precision molded sleeves and hubs with no bolts, pins, flanges, or protrusions to affect balance or safety. The nylon sleeve permits misalignment up to 5° for Dentex and Nyflex couplings and 3° for the Mite.When completely assembled, the Mite coupling weighs less than 1lb and the Nyflex only 3.50 lbs. Weights for Dentex 2 Spirolox Retaining Rings Sleeve is securely held on the hubs by these spring- steel retaining rings. They can be removed in seconds, yet they’ll withstand 5,000 lbs endthrust.
