Our worm gearboxes offer standard reduction ratios from 5:1 to 100:1 in single-stage designs. Common ratios include 5:1, 10:1, 15:1, 20:1, 30:1, 40:1, 50:1, 60:1, 75:1, and 100:1. Multi-stage configurations can achieve higher ratios. See our worm gearbox product page for detailed specifications and torque ratings.

Yes, most Anand Gears worm gearboxes feature self-locking capability due to high friction between the worm and phosphor bronze wheel. This prevents backdriving, eliminating the need for mechanical brakes—ideal for hoists, elevators, and load-holding applications. Self-locking efficiency varies by ratio; higher ratios provide more reliable self-locking action.

NMRV reducers have aluminum housing, are lighter and more compact, suited for low-to-medium power applications, and offer easier installation. Cast iron worm gearboxes (WPSE, WPSM, WPSA series) are heavier, more robust, handle higher continuous loads and thermal ratings, and are preferred for heavy-duty industrial use. Cast iron also provides better heat dissipation and longer service life.

Yes, we regularly manufacture custom shaft configurations including hollow output shafts, solid shaft extensions, keyway specifications, coupling flanges, and encoder mounting provisions. Our engineering team can design custom configurations based on your mechanical interface requirements. Lead times depend on complexity; contact us for custom quotes.

Helical gearboxes typically operate at 95-98% efficiency per stage, significantly higher than worm gearboxes (50-90% depending on ratio). This means lower power loss, reduced heat generation, and lower operating costs for high-duty applications. Multi-stage helical designs maintain excellent efficiency even with high reduction ratios.

Helical gearboxes excel in continuous-duty applications including conveyors, pumps, compressors, mixers, crushers, and heavy machinery. They are preferred where energy efficiency matters, heat dissipation is critical, or high-speed gearboxes are required. Their smooth, quiet operation suits noise-sensitive environments like food processing and pharmaceutical manufacturing.

We manufacture helical and bevel gearboxes in multiple size categories handling power ratings from a few kilowatts to several hundred kilowatts. Standard sizes cover reduction ratios from 2.5:1 to 50:1+ depending on type. Custom sizes can be engineered for specific applications. Contact sales for your exact power and torque requirements.

Anand Gears manufactures mechanical screw jacks with load capacities from 5 kN to 350 kN. Both trapezoidal and ball screw designs are available. We offer manual hand-wheel operation, motorized electric drive, and synchronized multi-jack systems for precision vertical positioning and load holding in heavy industrial equipment.

Screw jacks are used for vertical load positioning, lifting, and holding in applications including presses, die-casting machines, assembly platforms, injection molding equipment, and heavy machinery. They excel where precise height control, load safety, and compact installation space are required. Self-locking designs eliminate load drift.

Yes, multiple screw jacks can be synchronized using chain drives, shafts, or electronic control systems for balanced platform lifting. This prevents tilting and ensures safe, even load distribution. Synchronized jack systems are common in printing presses, platforms, and precision positioning equipment requiring multi-point load support.

Anand Gears provides 12-month warranty against manufacturing defects and material failures under normal operating conditions. Warranty covers parts replacement and repair labor. Exclusions include misuse, improper maintenance, bearing failures from external loads, and damage from foreign material in oil. Extended warranty options are available upon request.

Start by calculating required input power (kW), input speed (RPM), and desired output speed. Determine reduction ratio and required output torque. Identify duty cycle (continuous, intermittent, shock loads), mounting method, environmental conditions, and space constraints. Our selection guide covers these factors; contact our engineering team for personalized recommendations.

Service factor accounts for duty cycle severity—continuous duty requires higher safety margins than intermittent use. Standard service factors range 1.0 (light intermittent) to 2.0+ (heavy shock loads). Always apply appropriate service factor to input power when selecting gearbox rated power to ensure reliable, long-term performance and avoid premature failure.

Reduction ratio = Input Speed (RPM) ÷ Output Speed (RPM). For example, if a motor runs 1500 RPM and you need 150 RPM output, the ratio is 1500 ÷ 150 = 10:1. Output torque equals input torque multiplied by the reduction ratio and gearbox efficiency. Our gear calculation tools simplify these computations. See our glossary for technical definitions.

Most Anand Gears worm gearboxes use ISO VG 220-320 mineral oil or equivalent synthetic products. Helical and bevel gearboxes typically use ISO VG 150-220. Always refer to your gearbox manual for exact viscosity and additive recommendations. Proper lubricant selection ensures optimal cooling, wear protection, and seal compatibility. Avoid mixing oil types.

Standard Anand Gears gearboxes operate safely from -10°C to +70°C ambient temperature. Maximum continuous operating oil temperature is typically 80-90°C. Thermal rating specifications provided with each model indicate safe power transmission at temperature. Proper lubrication, ventilation, and cooling prevent overheating and extend service life significantly.

Mechanical power (kW) = Torque (Nm) × Speed (RPM) ÷ 9550. For electrical motors: Power (kW) = Voltage × Current × Power Factor ÷ 1000. Always factor in service factor—multiply calculated power by 1.25-1.5 for intermittent duty or 1.5-2.0 for heavy shock loads. This ensures adequate gearbox rating and reliability.

Gearbox life depends on proper gearbox selection (not undersized), regular oil changes (every 2000-3000 operating hours), clean operating environment, correct shaft alignment, appropriate mounting torque, and avoiding shock loads. Well-maintained gearboxes often exceed 10+ years service life. Neglected maintenance dramatically reduces life and increases failure risk.

Single-stage gearboxes have one gear pair, achieving ratios up to 100:1 in worm design. Multi-stage gearboxes combine multiple gear pairs for very high reduction ratios (100:1 to 1000:1+) or specialized torque/speed profiles. Multi-stage designs are bulkier but handle extreme ratios and maintain better efficiency than overdriven single-stage units.

Yes, we manufacture custom flange mounts, foot mounts, shaft extensions, coupling interfaces, and specialized mounting provisions. Common customizations include encoder mounting pads, limit switch brackets, and fan mounting provisions. Our engineering team integrates your mounting requirements into the design. Contact us for custom specifications.

Backlash is the small gap between mating gear teeth allowing for thermal expansion and lubrication. Controlled backlash (typically 0.1-0.3mm depending on size) is essential for smooth operation. Insufficient backlash causes binding and noise; excessive backlash reduces accuracy in positioning applications. Specifications are provided with each gearbox model.

Many Anand Gears gearboxes handle reversing duty (forward/reverse cycling). However, check if self-locking capability is acceptable for your application—self-locking worm gearboxes cannot be backdriven. For true reversing duty, specify reversible-duty capability during ordering. Our sales team can recommend suitable designs for your duty cycle.

Shaft misalignment causes premature bearing wear, vibration, and noise. Use dial indicators to align input/output shafts to <0.05mm runout. Check both angular (angle) and parallel (offset) alignment. Tighten all mounting bolts evenly to specified torque. Poor alignment is a leading cause of premature gearbox failure and reduced service life.

Yes, Anand Gears stocks spare parts including gaskets, seals, bearings, shafts, gears, and housings for all our gearbox models. Original replacement parts ensure proper fit and performance. We maintain parts inventory for 10+ years of discontinued models. Order spare parts through our sales team with your gearbox model number.

We offer gearbox maintenance services including oil changes, filter replacement, inspection, bearing replacement, seal renewal, and performance diagnostics. Our technicians can visit your facility for on-site maintenance of installed gearboxes. Regular preventive maintenance extends gearbox life and minimizes production downtime.

Excess noise often indicates low oil level, contaminated oil, misalignment, or worn bearings. Check oil level and condition first. Verify shaft alignment and mounting bolts. If problems persist, contact our technical support team—we can diagnose issues remotely or arrange on-site inspection. Early troubleshooting prevents catastrophic failure.

Yes, many gearbox issues can be repaired including bearing replacement, seal renewal, gear re-machining, and shaft repairs. Send photos/videos of the issue to our technical team for assessment.
