Description
Product Overview
The 7JE Yungrag Coupling Sleeve is a precision‑engineered component designed specifically for the S‑Flex series of flexible couplings. Constructed from high‑grade synthetic rubber blended with specialty additives, the sleeve delivers exceptional shock absorption and torque transmission while maintaining a compact footprint. Its dimensions—4.34 inches outer diameter and 2.19 inches elastomer length—provide a perfect fit for a wide range of industrial equipment, including air compressors, pumps, mixers, blowers, and motor assemblies from leading manufacturers such as Atlas Copco and Ingersoll Rand. The sleeve is rated for a nominal torque of 725 in‑lb, making it suitable for medium‑to‑high load applications where reliability and durability are paramount.
Usage
Designed for harsh industrial environments, this coupling sleeve excels in applications where exposure to oil, elevated temperatures, and abrasive particles is common. It is ideal for use in manufacturing plants, processing facilities, and any setting that demands continuous power transmission with minimal maintenance. Whether installed on a high‑speed compressor, a low‑speed pump, or a variable‑speed mixer, the sleeve’s rubber composition ensures smooth operation, reduces vibration, and protects downstream components from shock loads. Its universal fit across multiple brands and models simplifies inventory management and reduces downtime during equipment changeovers.
