Import Gear Couplings — Buy in Bulk from Supplier in India

Roma Mechanical Engineering Co. offers the GEARFLEX double‑engagement gear coupling, a flexible unit built from two gear hubs, two flanged geared sleeves, bolts, grease nipples and O‑rings. The hubs are machined from tested forged steel while the sleeves are either forged steel or graded cast steel, depending on size and requirement. Both hubs and sleeves are heat‑treated to a hardness of 240‑280 BHN, delivering wear resistance for prolonged service. Bolts are fabricated from high‑tensile steel and the O‑rings use specially bonded rubber designed to retain compression over time.

Roma provides several variants including single‑engagement, mill‑motor, spacer, brake‑drum, vertical, disengaging, continuous‑sleeve and extended‑hub types, allowing selection to match shaft speed and torque demands. Typical torque capacity for the standard range spans from about 5 kNm to 150 kNm, with angular misalignment tolerance up to ±2° and parallel offset up to 0.5 mm, which aligns with industry norms for medium‑size power transmission. The couplings operate with grease lubrication delivered through nipples and retained by O‑rings; oil lubrication can be fitted via optional oil plugs. Optional sealing options such as felt, oil or detachable seals are offered on request, expanding suitability for contaminated or high‑temperature environments.

These couplings are commonly installed in motor‑driven pumps, conveyor gearboxes and industrial machining centres where high torque‑to‑weight ratio and low moment of inertia are required. Buyers typically seek a supplier that can confirm material certifications, heat‑treatment reports and packaging dimensions before placing an order. Roma does not list minimum order quantities, lead times or price bands, so importers should request detailed trade terms and payment conditions directly.
