The SKF Y-bearing XGG KTTB series is an insert with spherical outer ring and set screw locking, designed to be mounted in split plummer block or flanged housings. It is used in equipment where the shaft rotates at moderate speeds and a self-aligning unit with simple mounting and quick disassembly is needed. Its sealed construction protects it from dust and moisture, making it suitable for demanding industrial environments. MR Accesorios Industriales distributes this line as an official brand.

The series designation combines letters and numbers that identify the insert type and its variants. In the examples XGG1014KTTB, XGG1100KTTB and XGG1108KTTB, the prefix XGG indicates the category of Y-bearings with spherical outer ring. The central numeric block indicates the bore diameter size and the bore configuration. The suffix KTTB defines the sealing type and the locking system: the K refers to a tapered or cylindrical bore depending on the case, TT to a double-lip seal, and B to the presence of set screws on the inner ring. Knowing these codes allows you to order the exact replacement.

These bearings are used in belt conveyors, bucket elevators, mixers, mills, conveyor belts and agricultural machinery. In Argentina they are common in food plants, cement plants, quarries and poultry facilities, where dust and moisture require sealed units. They are also found in pumping equipment, fans and low-power transmission systems. The combination of self-alignment and set screw locking simplifies mounting on commercial shafts and reduces downtime in corrective maintenance.

To select the appropriate Y-bearing, verify the shaft diameter and the type of housing where it will be seated. The KTTB seal protects against contaminants, but if the environment has abundant water or fine particles, additional seals should be evaluated. When mounting, clean the shaft and apply a thin layer of lubricant before inserting the bearing. Tighten the set screws evenly and with the recommended torque to avoid deformation. Check the housing alignment and leave the necessary axial clearance for thermal expansion. Periodic lubrication with good quality grease extends service life.

Regarding equivalents, Y-bearings are manufactured under international standards that allow units to be interchanged between different brands as long as the main dimensions match: bore diameter, outer diameter, width and locking type. However, sealing suffixes and tolerances can vary between manufacturers, so it is essential to compare technical specifications before replacing. For SKF lines, the XGG KTTB series maintains its nomenclature, but other brands may use different codes for the same configuration. Consult us if you have doubts about interchangeability.
