Types of Bearings


1. Ball Bearings

Ball Bearings are probably one of the most common types of bearings that are useful for different purposes. These types of bearings are found in applications where there is lesser load, hence this type of bearing can handle radial and thrust load having the wide range of operating speeds.

Ball bearings are pretty much versatile in nature. Different applications where ball bearings are used are gear reducers, electric motors, and pumps. Apart from this, ball bearings also serve different purposes for heavy industrial equipment like pumps, extruders, large motors, mining, oil and gas drilling and mining applications

Types of Ball Bearings are:

Deep groove

Angular Contact

Angular Contact Double Row

2. Cylindrical Roller Bearings

Cylindrical Roller Bearings are made to hold heavy radial loads, they are usually used in applications like conveyor belt rollers, etc. In this case, the bearing has a roller that is cylinder hence the point of contact is a line. This helps to spread the load over the larger area that allows the bearing to handle greater loads in comparison to a ball bearing. Cylindrical bearings are made with the single row, two rows or multi-rows of rolling elements that help to meet an application’s radial load requirement.

Roller bearings are available in many standard series and configurations that are used in the wide number of industries. The unique characteristic of having a high load capacity, industrial interchange ability and moderate speed rating makes its design, the most popular bearing designs available.

Types of Cylindrical Roller Bearings are:

Single-row bearing

Journal bearings

Double row bearings

Full Complement Single Row bearing

Full Complement Double Row bearing

Multirow bearing

Cluster Mill bearing

3. Tapered Roller Bearings

Tapered Roller Bearings are common in industrial applications, the tapered rollers in the bearings allow it to accommodate heavy radial, axial and combination loads. The bearing configuration and its flexible loading capability are designed from single cups, double cups, and cones. Hence, they are used in almost every industry use.

The standard tapered roller bearings have a “pin-type” design that makes it versatile to be used in the variety of applications. It is most commonly used in applications having very high loads and high speeds.

Types of Tapered Roller Bearings are:

Single Row bearing

Double Row (TDO, TDI, TDIE) bearing

Four-Row Bearing

4. Spherical Roller Bearings

Spherical Roller Bearings are rolling element bearings that help rotation with low friction and it also allows angular misalignment too. The misalignment is permitted due to the spherical internal shape of the outer ring and spherical rollers. Spherical roller bearings support rotating shaft into the bore of an inner ring that could be misaligned as compared to the outer ring.

As their name represents, they are NOT truly spherical in shape, the rolling elements in roller bearings are more cylindrical in shape, slightly over-inflated. Spherical roller bearings are used in varieties of industrial applications that have heavy loads and moderate speeds. Most common applications are wind turbines, gearboxes, pumps, mechanical fans, construction equipment, marine propulsions, off-roading vehicles, etc.

Types of Spherical Roller Bearings are:

Spherical Plain Bearings

Rod Ends, Spherical Ball Bearings

Many Other Dimensional Series Varieties

5. Thrust Bearings

Thrust bearings are a type of rotary bearings, they allow rotation between the parts and are so designed to support high axial load while being parallel to the shaft. Different thrust bearings are used for supporting different amounts of axial loads.

The ball thrust series can relatively handle lighter loads while the Angular contact series can handle the load from both radial and thrust loads in both directions. There are several designs and configurations available in thrust bearings depending on the industry type and applications for they are used.

Types of Thrust Bearings are:

Ball Thrust bearings

Ball Angular contact

Double Acting Angular Contact

Cylindrical Roller

Crane Hook Cylindrical Roller

Light Duty Double Acting Cylindrical

Center Plate Double Acting Cylindrical

Spool type Double Acting Cylindrical

Tapered Roller

V-Flat Tapered Roller

Double Acting V-Flat Tapered Roller

Screwdown Thrust Tapered Roller

GEAR COUPLING

Curved Tooth Flexible Gear Couplings are unique of its kind in the field of mechanical power transmission. These gear couplings have outstanding features like mechanical flexibility and compensation of misalignment (angular, parallel and axial) of the connected shafts. These can used extensively in various industries like rolling mills, cranes, cement plants, dredgers, conveyors and elevators, rubber & plastic industries, compressors, fans, blowers, and in many other industries. These couplings consist of to halves with internal teeth having curved/ crowned shape & two outer sleeves with internal spur teeth. Thus coupling ensures a greater flexibility because of its well designed tooth profile which allows a maximum area of contact between the external and internal teeth under any misaligned condition. Special ‘O’ rings have been provided at the end of the coupling hubs to prevent any leakage of the lubricant and entry of dust inside the coupling.

Up to size FGC - 03 both hubs and casings are made of steel confirming to 45C - 8 of IS : 1570. From size FGC - 04 casings are made of cast steel confirming to 23 - 45 of IS : 1030. Teeth of the couplings are heat treated to a hardness of HB 240 - 280. Bolts are also made of steel confirming to 45C - 8 of IS : 1570.

Couplings are also available in the following versions:

Full Geared Flexible Type,

Half Geared Flexible Type,

Spacer Type

Mill Motor Type

Floating Shaft Type

Brake Drum Type

Vertical Type


TYRE COUPLINGS

GRID (RESILIENT) COULINGS
