3. Characteristics of Magnaloy Flexible Drive Coupling:
– Magnaloy Flexible Drive Coupling is manufactured by Magnaloy/USA.
– Magnaloy couplings feature a “Magie structure” material that is 76% lighter than iron and 36% lighter than aluminum. This is a significant advantage of Magnaloy couplings compared to other flexible coupling types.
– The coupling consists of 2 “Magiê structure” hubs and a cushioning rubber insert.
– Reduces load on shafts, bearings, and pumps, extending component lifespan.
– Easier handling and installation. Resistant to rust and corrosion.
– Magnaloy’s close machining tolerances (TIR is 0.002″) ensure vibration-free operation and easy, precise alignment without the need for special tools.
– Magnaloy couplings are available with special features including interlocking holes, with steel’s quick abrasion resistance capability.
– Magnaloy Couplings come with various flexible insert options, allowing customizable design performance for multiple applications. All materials are fully insulated, as Magnaloy’s design eliminates all metal-to-metal contact.
– Note: Before tightening the screws, run the coupling and check for separation between shafts or wires. Recheck alignment and tighten screws.
– Magnaloy’s cushioning rubber inserts come in various designs:
+ Nitrile, 70A durometer …..
Standard elastomer material provides excellent pressure for oil products and superior compression properties.
+ Urethane, 90A durometer …..
Excellent physical properties. Note: Urethane material tends to soften when exposed to high temperatures or wet conditions.
+ Hytrel, 50D durometer …..
– Superior physical properties and provides excellent fluid compatibility and high-temperature characteristics.
