Digital solution connects steel melt shop operations with ladle and crane tracking and thermal loss prediction for higher casting speeds and additional output of 24,000 tonnes per annum.
Sleeve bearings Th e life of a sleeve bearing is practically infi nite, pro-vided that its operation remains within the specifi ed conditions. Motors have sleeve bearings at both ends. Th e bearing on the D end is the guide bearing and means that it can tolerate a limited non-axial force. Th e bearing on the N drive end is isolated.
Rolling Bearing Lubrication for Critical Running Conditions. Grease is the most common type of lubricant used for rolling bearing lubrication today. About 90 percent of all bearings are lubricated in this manner. It is important to select the right grease for specific requirements and to calculate the lubricant life cycle.

The bearing Dynamic Capacity, C, is defined as the constant stationary radial load which a rolling bearing can theoretically endure for a basic rating life of one million revolutions. Values for this important bearing parameter, C, are shown in each bearing table except Crane Hook bearings.
On smaller mills rigid or swivel type bearings support the mill trunnions. The lower half of such bearings are lined with bronze or a special mill babbitt which is peened in place and bored to fit the trunnion. In all cases a low bearing pressure is maintained …
Sunstate Cement Ltd. had performed visual inspection of the Tube Mill No1 trun-nion drive end bearing. During this inspection they found the bearing was in a reasonable condition after 28 years of service and decided to extend the service life by rotating the outer ring by 180°, what is a common practice for this type of application.
Bearing Cleaning. When bearings are inspected, the appearance of the bearings should first be recorded and the amount and condition of the residual lubricant should be checked. After the lubricant has been sampled for examination, the bearings should be cleaned. In general, light oil or kerosene may be used as a cleaning solution.

7. Lubrication of Bearings In a bearing, lubrication forms a thin oil film on both the rolling surface and sliding surface to prevent metal-to-metal contact. The benefits of lubricating a rolling bearing can be summarized as follows: (1) Alleviation of friction and wear (2) Removal of friction heat (3) Longer bearing life (4) Rust prevention
Generally, the optimal bearing must be selected to suit the nature of the machine, the area within the machine, the spindle specification, bearing type, lubrication system and drive system of the intended machine through considerations of the design life, 1Bearing selection Confirm operating conditions of bearing and consider bearing type.
