• Thermal efficiency
  A large oil reservoir ensures maximum thermal efficiency.
• Lubrication
  Splash lubrication results in positive and ample flow of oil to all the gears and bearings.
• Correct tooth contact
  A correct tooth contact is ensured by , corresponding bearing bores are maintained with a precise and accurate tolerance.
• High efficiency
  High efficiency is ensured by precision gearing and accurate bearings.
• Maximum tooth contact
  Maximum tooth contact is obtained by precision cutting of gear tooth to involute shape.
• Precise Tolerance
  For having an accurate tolerance between the gear centres there is use of anti-friction type bearings.
• Oil leakage
  A positive seal prevents oil leakage at high/low speed shafts.
• Gear Material
  Gears are made up of top grade carbon Steel that are also heat treated and precision cut.
• Shafts
  Shafts with pinions are made up of carbon/alloy steel with close tolerances.
• Reduction ratios
  Use of single, double and triple reduction units.
• Housings
  Housings are typically made of stress relieved fabricated steel structure. Proper ribs placed underneath the bearing seats ensures strength while walls with sufficient thickness can withstand severe stresses for challenging applications

• The Gear teeth is cut with the metric module system.
• Housings are made of cast iron and then machined with very tight tolerance to ensure a perfect alignment of gears.
• All pinions are integrated with the shafts.
• In case of horizontal gear units the unit comprises of helical gears whereas in case of vertical gear units,spur gears are used for reduction.

• What is the Horse Power of drive and the RPM
• What is the type of drive whether : motor/turbine/diesel Engine
• What is the input and output RPM
• What is the configuration that is whether horizontal or vertical
• What would be the atmosphere
• If there is any shock load
• What is the Extension of input and output shafts
