Descrição do sufixo
BThe Significance Of This Sign Is Not Determined Separately. They Are In Need For Appointment Of Special Features Of The Construction Of Internal Form External Uses. In General, The Use These Only Temporarily, During A Transitional Time To Avoid Confusion. In Some Cases, They Also For Permanent Appointment Of Bearings And Parts Of The Same Type And Size, But With A Differ Interior Design. (Source: Ina-Catalogue No. 307)
The SL182918-B-XL-C3 INA is a single-row, full-complement cylinder bearing. This bearing type has a solid outer and inner ring and a high number of cylindrical rollers. These rollers are guided between the ribs of the rings. Since there is no cage, the maximum number of rolls can be used. As a result, these bearings can support very high radial loads. However, the maximum speed is lower than the speed of cylindrical roller bearings with cages. Single-row full-complement cylindrical roller bearings can also support axial forces in one direction. They are used as support bearings. Support bearings allow axial displacement of the shaft relative to the housing in one direction. The shaft is located axially in the other direction.
The SL182918-B-XL-C3 INA is an X-life type cylindrical roller bearing. X-life bearings provide better performance than normal cylindrical roller bearings due to a special internal construction. Contact surfaces, steel grade and rolling bodies are of a higher quality. X-life bearings combine a higher load capacity with a longer service life. The bearings generate less heat and allow for higher speeds. Finally, X-life bearings allow for longer maintenance intervals compared to normal cylindrical roller bearings.
