Features, Part Name, and Marking of the bones swiss ceramic bearings

The bones swiss ceramic bearings used in a rolling mill is limited in its dimensions by the roll neck diameter and minimum roll diameter. The bones swiss ceramic bearings is so designed that its load rating may be as large as possible within this limited space. This type of bearing consists of two sets of cone assemblies, three cups, and two cup spacers. To facilitate installation and removal of the roll and chock, this type of bearing is loose-fitted to the roll neck. Accordingly, lubrication to the fit surface is essential to prevent scoring between the roll neck and bearing bore due to creep. To prevent wear and seizure of cone and cone spacer, oil slots are provided on one side of the cone and both sides of the cone spacer. Double-row cups and cup spacers are provided with oil holes and oil grooves to supply the lubricant.

The bones swiss ceramic bearings combines the traditional cylindrical roller bearing and spherical roller bearing configurations. Its proprietary outer race and roller profiles plus a cylindrical inner ring combine the key attributes of both bearing types. This unique three-point contact design geometry provides simultaneous misalignment and axial displacement performance, optimizes contact stress distribution, and helps promote roller stability. The result is a more dynamic, more reliable bearing.

The bones swiss ceramic bearings consists of an inner ring, outer ring, and roller/retainer assembly. The separable components simplify installation, removal, and inspection. The retainer holds the rollers in position, creating a single assembly that prevents the rollers from being damaged during mounting and dismounting. The inner ring and outer ring can be installed in either direction, helping to avoid common mounting errors. No special tooling is required.

The features of the bones swiss ceramic bearings

Hair cracks caused in the cone side surfaces by creep may lead to cracks in the cone. To prevent such cracking and to enhance the shock resistance of the bones swiss ceramic bearings, the bones swiss ceramic bearings rings are made from carburized steel usually. The cage is designed as a window type or pin type.

In addition to the bearing number, the bones swiss ceramic bearings is provided with a serial number that is common to one set of bearings and matching symbols indicating the combination order. The serial number is used to prevent mismatching during the combination of bearings while matching symbols show the proper position of each part within a bearing. A wrong combination of these parts may cause an excessively small bearing clearance, resulting in a seizure. On the other hand, an excessively large clearance due to a wrong combination may cause a reduction of the load zone resulting in shorter fatigue life.

The cup of the bones swiss ceramic bearings is provided with load position numbers at four equally divided points around the circumference.  (These numbers are provided on the cone if the cup rotates.) So that the bones swiss ceramic bearings life can be extended, each time the bearing is reassembled after disassembly and cleaning, shift the load position numbers by 90 to change the load zone.

The bones swiss ceramic bearings have seals positioned at both end surfaces and the middle bore notch. Basically, this type of bearing is similar to the four-row tapered roller bearing and has the following features:

1. Substantial reduction in the consumption of lubricating grease.

2. Longer interval until disassembly and cleaning, thereby cutting down on the maintenance costs )

3. Cleaner environment around the rolling mill and roll shop )

4. Prevention of sudden failure due to foreign particle entry )

5. Longer bearing life is achieved by preventing water intrusion )

6. Load capacity remains just as high as that of four-row tapered roller bearings without seals

Basically, there are two-seal and four-seal types of the bones swiss ceramic bearings. The standard feature of the sealed-clean tapered roller bearing is its ability to operate for a long time without the need for regreasing. Due to this feature, there are no oil holes in the cup spacers to supply lubrication to the bearing, but in the case of severe operating conditions, it could be designed to enable lubrication by making a lubrication groove and oil holes in the cup spacers. There is also a type compatible with oil-air lubrication.

In addition to the bearing numbers, the bones swiss ceramic bearings is provided with a serial number that is common to one set of bearings and matching symbols indicating the combination order. The serial number is used to prevent mismatching during the combination of bearings while matching symbols show the proper position of each part within a bearing. A wrong combination of these parts may cause an excessively small bearing clearance, resulting in a seizure. On the other hand, an excessively large clearance due to a wrong combination may cause a reduction of the load zone, resulting in shorter fatigue life. The cup of a bearing is provided with load position numbers at four equally divided points around the circumference. (These numbers are provided on the cone when the cup rotates.) So that the bones swiss ceramic bearings life can be extended, each time the bearing is reassembled after disassembly and cleaning, be sure to shift the load position numbers by 90° to change the load zone.
