Housing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to make sure proper radiation against temperature generated when products are operated at their maximum capacity
Helical Gears & Pinion Shafts These possess involute profile teeth and so 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 stopping leakage of oil and entry of dust.
Bearings Antifriction bearings used to ensure long service life and also high process efficiency.
Path of rotation Though gearboxes are ideal for rotation in either direction, running in and functional test run is done toward rotation specified.
Lubrication For regular speeds, splash lubrication is provided. At places where splash lubrication is not effective, a built-in/individual mounted lubrication oil pump is utilized for forced-feed lubrication.
Cooling Additional cooling devices provided inside lower part of housing based on power to 
be transmitted and ambient temperature.
Overhung Loads Bearings can withstand overhung loads that arise because of mounting of toned and V-belt pulleys, equipment wheels and chain sprockets of appropriate dimensions.
Painting Casting areas painted with linear epoxy primer (both internally and externally).
High load carrying capacity
Minimal noise generation
CONSTRUCTION FEATURES
A few of the standard structure features include:
Finding use in Cranes & Hoists, these can be offered in range from 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 which includes –
Sizes
Dimensions
These gearboxes provide ease of servicing along with rigid, robust and torsion resistant casing so as to ensure long support life standards. The casing is constructed of quality close grained Grey Cast Iron that’s proportioned to ensure proper radiation of heat generated when the units are operated at maximum capacity. Further, suitable ribs are positioned under bearing seats for high strength with walls of adequate thickness to withstand most severe stresses faced during operation. Further, we also hold expertise in providing housing in cast metal/fabricated steel finish if required.
