What types of industrial gearboxes does Anand Gears manufacture?

Anand Gears manufactures worm gearboxes (sizes 50-200, up to 25 kW), NMRV worm reducers (sizes 025-150, up to 18.5 kW), helical gearboxes (H/K/F/S series, up to 200 kW), bevel gearboxes (spiral bevel, 90° shaft angle), planetary gearboxes (3:1 to 512:1 ratio), geared motors (0.12-30 kW), extruder gearboxes, and machine screw jacks (5 kN to 350 kN).

What is the difference between a worm gearbox and an NMRV worm reducer?

A worm gearbox uses a cast iron housing and is designed for heavy-duty applications requiring up to 25 kW power and 4,200 Nm torque. NMRV worm reducers use lightweight aluminium die-cast housings, come in sizes 025 to 150, are universally mountable, and are ideal for applications needing up to 18.5 kW power and 1,550 Nm torque. NMRV reducers are more compact and cost-effective for lighter-duty applications.

What gear ratios are available for AEI worm gearboxes?

AEI worm gearboxes are available with gear ratios from 5:1 to 100:1 in single reduction and up to 3600:1 in double reduction configurations. NMRV worm reducers offer ratios from 5:1 to 100:1. Helical gearboxes offer higher efficiency at up to 98% with ratios suited to each series. Planetary gearboxes provide ratios from 3:1 to 512:1 in 1 to 3 stages.

Which industries use AEI gearboxes?

AEI gearboxes are used across food & beverage, automotive, energy, plastics & rubber (extruder gearboxes), material handling (conveyors, elevators), packaging machinery, textile machinery, cement plants, steel mills, and general industrial automation.

What is the maximum power rating of AEI helical gearboxes?

AEI helical gearboxes are available with power ratings from 0.12 kW to 200 kW across the H-Series (parallel shaft), K-Series (helical-bevel), F-Series (parallel shaft flange), and S-Series (helical-worm) configurations. They achieve up to 98% efficiency and are suitable for heavy-duty industrial applications.

Does AEI provide custom gearbox solutions?

Yes, Anand Gears provides custom gearbox solutions tailored to specific application requirements. With 30+ years of manufacturing experience, in-house design capability, and a well-equipped facility in Bhayander East, Mumbai, AEI can design and manufacture gearboxes for specialized industrial applications.

What specialty gearboxes does AEI offer?

AEI manufactures specialty gearboxes including clutch-type gearboxes for manual engagement/disengagement, tube mill gearboxes for steel tube manufacturing, strip mill gearboxes for steel strip operations, lift duty gearboxes for elevators and hoists, shaft-mounted reduction gearboxes, and custom-built gearboxes for application-specific requirements. All specialty units are engineered in-house with 30+ years of manufacturing expertise.

Does AEI supply individual gears and gearbox spare parts?

Yes, AEI manufactures and supplies individual gears and spare components including spur gears (SS/MS, 10–30 inch diameter, 44–150 teeth), worm wheels (copper/MS, polished, up to 30 inch), worm shafts (precision machined MS), crown & pinion sets (module 1–6), and replacement gears, shafts, and bearings for all gearbox types. Contact +91 98203 83719 for spares inquiries.

What worm gearbox variants does AEI manufacture?

AEI manufactures multiple worm gearbox variants: standard worm gearboxes (50–200mm CD), adaptable worm gearboxes (6 shaft positions, 30–100mm CD), under-driven worm gearboxes (90–305mm CD), double worm reduction gearboxes (ratios up to 4900:1), vertical worm gearboxes for stirrer applications, NU series universal gearboxes (60–205mm CD), and V-type gearboxes. All use phosphor bronze worm wheels and case-hardened alloy steel worms.

What helical-worm gearbox options are available from AEI?

AG offers helical-worm gearboxes in several configurations: standard helical-worm (1–50 HP, 80–380mm CD, ratio 4:1–110:1), helical-worm with top-bottom shaft configuration, helical-worm with double output shafts, and crossed helical reduction gearboxes for non-parallel shaft power transmission. These combine the efficiency of helical gears with the compactness of worm reduction.
