The FAG cylindrical roller bearing of the SL...-TB-XL line is a single row bearing with a brass cage and a high-capacity design. It is used in applications where the radial load is high and the speed is also high, such as gearboxes, machine tools and transmission equipment. MR Accesorios Industriales supplies this brand and helps you identify the correct size from the part number engraved on the bearing or on your equipment's drawing.
The SL...-TB-XL designation is read in blocks. The letters SL identify the family of single row cylindrical roller bearings with a machined brass cage and high load capacity. The number that follows, as in SL192318-TB-XL or SL192319-TB-XL, is related to the size and the dimensional series: the higher the number, the larger the bore diameter and capacity. The TB suffix indicates the cage and window design, and XL the current generation of the product within the FAG catalog. To confirm the exact size for your equipment, send us the complete part number.
In Argentine industry these bearings appear in reducers and gearboxes, machine tool spindles, centrifugal pumps, industrial fans and belt or chain drive equipment. They are also found in food, cement and mining machinery, where radial loads are high and the environment demands a robust bearing. Because they are separable, they make maintenance tasks in the plant easier and allow component replacement without replacing the entire shaft.
To select the correct bearing, take into account the radial load, the rotation speed and the type of lubrication. The brass cage of the TB design tolerates demanding conditions well and allows operation with oil or grease depending on the mounting. During assembly, verify the alignment of the shaft and the housing, and avoid impacts on the ring edges. If the equipment operates with contamination, consider additional sealing or a bearing with integrated seals.
FAG cylindrical roller bearings are interchangeable with those of other European and Asian brands that respect the same dimensional designation and the same cage type. Interchangeability does not depend only on the bore and outer diameter: the width, the internal clearance and the cage design also matter. That is why it is advisable to compare the complete designation before replacing. If you have doubts, send us the old part number and the equipment's, and we will verify them together.
If you need this FAG bearing for equipment in operation, write to us on WhatsApp with the part number SL192318-TB-XL, SL192319-TB-XL or the one shown in your spare parts list. At MR Accesorios Industriales we will reply shortly with the available alternative and the corresponding quote. We can also advise you on mounting and lubrication so that the replacement lasts as expected.

Frequently Asked Questions
- What does the TB suffix mean on a FAG SL bearing?
- The TB suffix indicates a specific design of machined brass cage, with windows that guide the rollers. It is a configuration designed for high radial loads and moderate to high speeds. It is always advisable to respect the suffix when ordering the spare part.
- How do I know if the SL...-TB-XL bearing is the one for my equipment?
- Take the part number engraved on the old bearing or check the equipment's manual. Compare the complete designation, not just the bore diameter. If you cannot find the part number, send us a photo or the shaft and housing measurements on WhatsApp and we will help you identify it.
- Can a FAG bearing be replaced by another brand?
- Yes, as long as the dimensional designation and the cage type match. Interchangeability between brands is based on dimension standards, but the internal clearance and the cage design may vary. Verify those data before mounting an equivalent from another brand.
