Much of arb's success as a bearing manufacturer is largely due to its passionate pursuit of quality of lower cost. With a tremendous focus on manufacturing quality bearings and restrains on cost, it comes as no surprise that arb bearings limiteds is among india's prominent engineering companies.
Product Specification
Cylindrical roller bearings offer excellent resistance to instantaneous overloads and shocks.
They simplify assembly thanks to their detachable elements and allow, for certain types, axial displacement or low axial load, for other types.
Cages
The standard cage for these bearings is the polyamide cage which allows bearing operating temperatures of 120°C or 248°F (150° or 302°F peak). The standard cage for series 4 is in pressed steel. The machined brass cage is available on option. Large-dimension bearings are equipped with a machined brass cage. For special applications in which the synthetic material cage is unacceptable, a metal cage can be provided on request.
Capabilities
Loads and speeds
Cylindrical roller bearings are designed to
Withstand radial loads
Withstand moderate axial loads if the position of the shoulders on the rings allows them accept high speeds of rotation
Misalignment
Cylindrical roller bearings accept misalignment of about 0.06° thanks to the correction on the roller surface profile
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.
Product Specification
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.
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.
Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races.
MBP use improved ball quality to so to provide noise free bearings and smooth running
MBP ball bearings have an optimized surface finish on all the contact surfaces to provide the sufficient lubrications this allows the bearings to run cooler and last longer
