Founded in 1946, National Engineering Industries Ltd (NEI) is India’s leading bearings manufacturer and exporter, renowned for excellence in quality and delivery.
Taper Roller Bearings have a cup, cone and rollers which are tapered in shape. Rollers are restrained by a flange on the cone against which their large end slides. These bearings can take combined loads (radial and axial) simultaneously. Projection lines of the cup and cone raceways and rollers meet at a common point on the bearing axis.
The axial load carrying capacity of bearings increases with the increasing contact angle. Bearings are separable so a cup can be separated from cone assembly. Hence both can be mounted separately. The raceway and rollers have crown profiles. Improved surface finish of flange enables cooler running by forming a full lubrication film with the roller head.

Depending upon the application requirements taper roller bearings can come in different variants such as double row, four row, etc. The primary features of taper roller bearings are:
Tapered roller bearings are commonly used in applications where radial and axial loads need to be supported, such as automotive wheel hubs, truck axles, industrial machinery, and agricultural equipment.
They are designed to handle both radial and thrust loads efficiently, making them suitable for heavy-duty applications where precise rotation and durability are essential.
Roller bearings, including tapered roller bearings, are used to support rotating shafts or axles while minimizing friction and allowing smooth movement.
They find widespread use in various machinery and equipment, including automotive transmissions, industrial gearboxes, electric motors, and conveyor systems, where radial or axial loads need to be supported.
The four basic parts of a tapered roller bearing include the inner ring, outer ring, tapered rollers, and cage or retainer.
The angle of a tapered roller bearing, also known as the taper angle or cone angle, is the angle formed between the axis of the bearing and the surface of the tapered rollers. This angle determines the ability of the bearing to handle radial and axial loads and affects its load-carrying capacity and performance.
Tapered roller bearings are commonly made from high-quality alloy steels, such as chrome steel or bearing steel, which offer excellent strength, hardness, and fatigue resistance. These materials are chosen for their ability to withstand high loads and harsh operating conditions, ensuring reliable performance and longevity.
Tapered roller bearings have a unique shape characterized by tapered rollers arranged in a conical design. The inner and outer rings of the bearing assembly are also tapered to match the profile of the rollers, resulting in a compact and efficient design that can accommodate both radial and axial loads.
The main parts of a tapered roller bearing include the inner ring, outer ring, tapered rollers, and cage or retainer. These components work together to support radial and axial loads while allowing smooth and precise rotation of the bearing assembly.
Tapered roller bearings are typically installed by pressing the bearing onto the shaft or into the housing using a hydraulic press or bearing installation tool.
Proper alignment is essential to prevent damage to the bearing or shaft during installation. Once installed, the bearing should be securely mounted and aligned to ensure optimal performance and longevit
Tapered roller bearings are measured based on their bore diameter, outer diameter, and width dimensions. These measurements are standardized according to international standards, to ensure compatibility and interchangeability between different bearing manufacturers.
Additionally, the taper angle or cone angle of the bearing is also specified to determine its load-carrying capacity and performance characteristics.
