Turned bearings are often technically and economically favourable bearing solutions.
High loading capability, low weight, good corrosion resistance and small radial diameters are some good properties for turned bearings. The choice of the suitable material and the arrange of additional lubrication properly are important when using turned bearings.
Material:
Turned bearings and bearing elements can be manufactured in several copper alloys. The material will be chosen to meet the specific needs for each construction. This is important to reach the optimal performance for the life time, service and total economy. Properties for the standard materials are on the table. In addition to standard materials there are many other alloys to use when necessary.

Tolerances:
Turned bearings can be manufactured with tighter tolerances than wrapped thin walled bearings. The tolerance can be adapted to the needs of the construction. Therefore it is possible to reach the clearence which is wanted.
Design:
Turned bearings are always manufactured according to the customer drawings. Therefore the bearing can be designed to meet the needs of the specific construction. The design of lubrication grooves, quantity of the lubrication holes, tolerances and chamfering can be manufactured according to customer needs.
Lubrication:
Turned bearings from copper alloys are aimed to be additional lubricated. The need of the additional lubrication depends on the bearing material and the general conditions of the bearing solution. The design of the lubrication grooves, the choice of the lubricant and the general conditions of the bearing solution affect how the additional lubrication should be arranged. With the right material and design can also turned bearings be used with quite a long lubrication intervals.
