Casing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to make sure proper radiation against warmth generated when models are operated in their maximum capacity
Helical Gears & Pinion Shafts These have involute profile teeth and are constructed using high alloy case hardening steel.
Shafts Low speed shafts created from medium carbon steel that is duly high temperature treated and finished to high precision tolerance by grinding process, thus preventing leakage of oil and entry of dust.
Bearings Antifriction bearings used to make sure long service life in addition to high process efficiency.
Path of rotation Though gearboxes are ideal for rotation in either path, working in and functional test run is done in direction 
of rotation specified.
Lubrication For normal speeds, splash lubrication is provided. At places where splash lubrication isn’t effective, a built-in/individual mounted lubrication essential oil pump is utilized for forced-feed lubrication.
Cooling Additional cooling units provided inside lower part of housing depending on power to be transmitted and ambient temperature.
Overhung Loads Bearings can withstand overhung loads that arise because of mounting of flat and V-belt pulleys, equipment wheels and chain sprockets of suitable dimensions.
Painting Casting surfaces painted with linear epoxy primer (both internally and externally).
High load carrying capacity
Minimal noise generation
CONSTRUCTION FEATURES
Some of the standard building features include:
Finding make use of in Cranes & Hoists, these could be offered in range between 2 HP to 100 HP as per the specific process needs of the customers. Further, the superior Gear tooth geometry design also allows generation of maximum efficiency that includes –
