Rolta Bearings Ahmedabad, Gujarat

Bearings are among the most important components in the vast majority of machines and exacting demands are made upon their carrying capacity and reliability. Therefore it is quite natural that rolling bearings should have come to play such a prominent part in textile machinery.

Needle bearings provide high radial load capacity in limited diametral space applications. Drawn cup full complement bearings with a maximum compliment of rollers for highest load capacity in minimum space.

Cylindrical roller bearings have rollers that provide a modified line contact with the cylindrical inner and outer ring raceways, while the rollers are guided by ground ribs on either the inner or outer ring. The cylindrical shape allows the inner ring to have axial movement relative to the outer ring.

Tapered roller bearings utilize conical rollers and raceways, arranged so that the rollers and raceways meet at a common apex. The rollers are guided by contact between the large end of the roller and a rib on the inner ring. This provides high capacity for radial and single thrust loads.

Slim bearing series are manufactured to industry standard sizes. The slim bearing widths and sections (distance from bore to outside diameter) in each series remains constant regardless of the change in bore diameter. Due to the large diameters and thin sections of these slim bearing products, it is necessary to address measurement and inspection techniques.
