Round bottom barrel roller bearing, The angular position of the bearing relative to the axis in these bearings makes them suitable for bearing radial and axial loads. Another important feature of this product is its self-adjustability, which makes the roller bearing insensitive to shaft asymmetry.

Round bottom barrel roller bearing
These rolling bearings are separable, with the shaft washer together with the shelf and rollers forming one part and the enclosure washer forming the other part. The barrel rollers in this type of rolling bearings have an asymmetrical state, the large number of these rollers combined with the special design of the rolling slope gives them extremely high strength against axial loads while also having a relatively high rotational speed. There are also certain designs (E suffix) that have a higher load bearing capacity than the usual type.
Some series of this type of roller bearings are manufactured with a steel or machined brass frame, which is adjusted to the correct position by a bush embedded in the shaft washer hole. As mentioned earlier, round barrel floor roller bearings are self-regulating.
As the load increases, the permissible asymmetry decreases. For example, under the load Fa+2.7Fr=0.15Co, the asymmetry value for all three series reaches o1.5.
Round-barrel floor rolling bearings are capable of operating up to +200°C.
Lubrication of Round bottom barrel roller bearing
The use of oil in the routing of these rolling bearings is more suitable than the use of grease. The use of grease is also possible under special conditions such as light loads or low revolutions. The rotational speed of the rolling bearings with grease in cases where the shaft is vertical is half of the amount that can be applied when the shaft is horizontal.
