Bearings for Automotive and Industrial use

We are leading manufacturer, supplier and exporter of Ball Bearing in Ahmedabad, Gujarat, India. We manufactured all types of ball bearings like deep groove ball bearing, miniature ball bearing, angular contact ball bearing and thrust ball bearings in competitive prices. These bearings are majorly used in thresher machine, rotovator machine, dal mill machine, food processing machine, conveyor machine, automobile machine and pharma machinery & all types of agriculture machineries.

The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft). As one of the bearing races rotates it causes the balls to rotate as well.

Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other.

Grade: P0, P5,4. Notes: Tapered roller bearings with radial oriented mainly to bear radial and axial joint load. Bearing load capacity depends on the angle of the outer ring raceway, the greater the angle the greater the carrying capacity. This kind of bearing is separable bearings, rolling bearings according to the number of rows into single row, double row and four row tapered roller bearings. Single row tapered roller bearing clearance adjustment required to the user during installation; Double row and four row tapered roller bearing clearance from the factory has been given based on user requirements, users do not need to adjust.Tapered roller bearings have tapered inner and outer ring raceways, tapered roller arranged between the two. The surface of the projection lines of all cone bearing axis in the same point together. This design makes tapered roller bearings particularly suitable for bearing complex (radial and axial) loads. Most of the axial load bearing capacity is determined by the contact angle �± ; A angle increases, the higher the axial load capacity. Angle size of the computational coefficient e to represent; E greater the contact angle the greater the bearing axial load greater applicability.Tapered roller bearings are usually separated type, that is, with roller and cage assembly of the inner components of the composition of the inner cone with tapered outer (outer) installed separately.5. Application: Tapered roller bearings are widely used in automotive, mill, mine, metallurgy, plastics and machinery.6. Packing: Single colour boxes or industrial packing, carton around 22kg, then into wooden or steel pallet.

Product Specification

The inner and outer ring raceways are segments of cones and the rollers are also made with a taper so that the conical surfaces of the raceways and the roller axes if projected, would all meet at a common point on the main axis of the bearing.>

This conical geometry is used as it gives a larger contact patch, which permits greater loads to be carried than with spherical (ball) bearings, while the geometry means that the tangential speeds of the surfaces of each of the rollers are the same as their raceways along the whole length of the contact patch and no differential scrubbing occurs. When a roller slides rather than rolls, it can generate wear at the roller-to-race interface, i.e. the differences in surface speeds creates a scrubbing action. Wear will degenerate the close tolerances normally held in the bearing and can lead to other problems. Much closer to pure rolling can be achieved in a tapered roller bearing and this avoids rapid wear.

The rollers are guided by a flange on the inner ring. This stops the rollers from sliding out at high speed due to their momentum.

The larger the half angles of these cones the larger the axial force that the bearing can sustain.

Tapered roller bearings are separable and have the following components: outer ring, inner ring, and roller assembly (containing the rollers and a cage). The non-separable inner ring and roller assembly is called the cone, and the outer ring is called the cup. Internal clearance is established during mounting by the axial position of the cone relative to the cup.
