2. Characteristics of Rathi-Ringfeder Flexible Couplings type L
– Manufacturer brand: Rathi-Ringfeder/India.
– The L type Jaw Flex Coupling is a standard shaft coupling in the industry, widely used with readily available stock options. It consists of three parts: two hubs made of sintered iron (L35 – L75), cast iron (L95 – L295), or aluminum (L50 – L110), and one spider shock absorber made of NBR rubber, Urethane, Hytrel, or Bronze.
– The L type Jaw Flex Coupling (Rathi-Ringfeder Couplings type L) is a flexible non-metallic-to-metallic coupling that will continue to operate if the resilient spider is worn or damaged (though not safely and should be replaced), capable of accommodating angular misalignment and parallel misalignment. It is resistant to oil, dust, dirt, moisture, and lubricating grease.
– The soft, jaw-type, flexible Jaw Flex Coupling from Rathi India (Lovejoy) is characterized by a unique rubber coating around the connecting components made of Nitrile rubber. The “Snap Wrap” coupling excels in quality, flexibility, installation speed, and maintenance, eliminating the need to dismantle the entire connected equipment for inspection or replacement of elements, a key benefit in reducing machine downtime.
