These specially designed Taper Roller bearings from Tata Bearings are built to take large axial forces and sustain large radial forces. In these separable roller bearings mounted in pairs with rolling elements and raceways tapered, the four basic components are the cone, cup, tapered rollers and cage. The cone, cage and tapered rollers together form the inner ring assembly, which is separable from the outer ring. To prevent concentrating of stress at the roller’s edges, the line contact between roller and raceway is modified by Tata Bearings by crowing both rollers and raceways.
This range of Tata Bearings is so designed that the extensions of raceway and roller, converge at a point on the axis of rotation. The tapered configuration facilitates the rolling motion of roller on raceway, and generates a ‘seating force’, pushing the roller against the large rib of the inner ring. This prevents the rollers from skewing off-apex, thereby always keeping them positively aligned and in contact with the inner ring rib.
These bearings can not only carry a combination of radial and thrust loads, the long-line contact between rollers and races enables them to carry high loads. Depending on the magnitude of the load to be carried, the contact angle of the bearings may be narrow or wide.
Taper Roller Bearings from Tata Bearings are being increasingly used in light, medium & heavy commercial vehicles, tractors, passenger cars – in the gear box, bevel pinion, front and rear wheels, water pump, etc.

Magneto Bearings from Tata Bearings are designed to, facilitate mountain in magnetos. These are separable bearings similar to single-row deep groove bearings. The outer ring has only one shoulder, forming one side of the ring groove, the other side being open. This design enables the outer ring to be removed end-wise from the inner ring, with the cage holding the ball complement. As magneto bearings transmit axial force in only one direction, two bearings are required to be mounted against each other for axial location on a shaft. Tata Magneto Bearings have found regular use in some of India’s reputed textile spinning mills.

When it comes to world-class bearings, promising top grade performance, longer life, competitive pricing, consistent delivery and service, Tata Bearings enjoys a distinct pride of place as one of India’s most valued brands. Tata BearingsOver the years, a highly performance-driven approach has helped Tata Bearings achieve an influential and crucial position in its target industry segment. The Bearings Division of Tata Steel is one of India's largest quality bearing manufacturers, with a production capacity of 37 million bearing numbers. It is the only bearings manufacturer in India to have successfully challenged the TPM Award from Japan Institute of Productive Maintenance, Tokyo in 2004 and continues to be the only manufacturer in India in this category to have won this recognition. Over the years, the Division has developed a unique organisational culture, being committed to the principles that have made the Tata Group one of India’s most dynamic and respected business houses bringing satisfaction and happiness to its consumers and business partners alike. Keeping pace with change Ever since the start of operations at the Kharagpur Facility, Tata Bearings has been constantly implementing new technology, and improving systems and processes through innovations in the field to deliver greater value to customers. In the initial stages the technology was obtained from M/s Societe Nouvelle de Roulements (SNR) - France, through a technical collaboration but presently all developments are carried out in-house. The Division has state-of-the-art IT hardware with ASP as the ERP platform for an online information system. Tata Bearings has a technical collaboration with Nachi Fujikoshi Corp., of Japan for developing and testing of key automotive bearings. For certain applications, it has also tied up with the IITs and CMERI Durgapur.
