The induction motors are extensively used at different levels. Small induction motors are used at the domestic level and the big induction motors are used at big industrial levels where the induction motors are used in big industrial units for various purposes. The induction motors are classified on the basis of their efficiency levels as per the International Efficiency 60034-30-1. On the basis of the efficiency levels, the induction motors are classified into 4 categories which are IE1, IE2, IE3, and IE4. The IE1 motors lie in the Standard Efficiency range. The IE2 motors lie in the High-Efficiency range. The IE3 motors lie in the Premium Efficiency range and the IE4 motors lie in the Super Premium Efficiency range. The efficiency range of each motor shows that the efficiency of the next series is better than the previous series. IE1 Motors (Standard Efficiency Motors) IE2 Motors (High Efficiency) IE3 Motors (Premium Efficiency) IE4 Motors (Super Premium Efficiency) To ensure the highest levels of customer satisfaction, the latest designs have been incorporated for the range of LT motors, ensuring better electrical performance as well as versatility in mechanical features. The range includes safe and hazardous area motors, energy efficient motors as well as motors for special applications like brake motor, re-rolling mill, cement mill, oil-well pump etc. The motors are available in various standards and customized configurations to respond to the exacting demands of the industry.

Worm gearboxes provide high torque with low-speed gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio than the helical gears. These worm reduction gears having screw type qualities are similar to helical gears, but its helix angle is typically comparatively larger) and its body is normally quite long in the axial direction. The gears in these gearboxes can be right or left-handed depending upon the purpose. Mounting option include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (single or double), with torque arm or torque limiter. Products Worm Gear Small/Medium/ Higher Series SNU Modular Universal Mounting ER Series

Pedestal (UC) Bearings units that are ready-to-mount bearing units, which are greased and sealed, and are able to compensate for misalignment of the shaft with respect of the housing.

Needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length. The ends of the rollers are relieved slightly to modify the line contact between the rollers and raceways. This prevents stress peaks at the roller ends to extend bearing service life.

Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis.

Tapered roller bearings have tapered inner and outer ring raceways and tapered rollers. They are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The projection lines of the raceways meet at a common point on the bearing axis to provide true rolling and low friction. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle . The size of the angle is related to the calculation factor e ( product tables): the larger the value of e, the larger the contact angle. A single row tapered roller bearing is typically adjusted against a second tapered roller bearing.

Cylindrical roller bearings are available in many designs, series and sizes. The majority are single row bearings with a cage. High-capacity bearings, double row bearings, multi-row bearings, single, double and multi-row full complement bearings (without a cage) and split bearings complete the SKF standard assortment provided here.

Angular contact ball bearings have raceways in the inner and outer rings that are displaced relative to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.

Deep groove ball bearings are particularly versatile. They are simple in design, non-separable, suitable for high and very high speeds and are robust in operation, requiring little maintenance. Because deep groove ball bearings are the most widely used bearing type, they are available from SKF in many designs, variants and sizes.

Flexible coupling is a cushioned drive type, transmitting the torque through rubber bushes which have excellent capacity to absorb shocks.
