The SKF Y-bearing insert of the XGGE KTTB series is a ball bearing with an extended inner ring, designed to be mounted directly on shafts and seated in split or pillow block housings. It is used in equipment that requires a simple rotating unit, easy to mount and with good radial load capacity. MR Accesorios Industriales supplies this line as part of its SKF bearing catalogue, with more than 80 years of experience in the field.
The designation of this series combines letters and numbers that identify the bearing type and its features. In examples XGGE20KTTB, XGGE25KTTB and XGGE30KTTB, the XGGE prefix corresponds to the Y-bearing series with extended inner ring and a specific sealing configuration. The number that follows indicates the shaft diameter in millimetres: 20, 25, 30, and so on up to 55. The KTTB suffix indicates the sealing type and the mounting grooves. Knowing these codes allows you to order the exact bearing you need.
These bearings are used in a wide variety of industrial and agricultural equipment in Argentina. You will find them in belt conveyors, grain elevators, mixers, fans, food industry machines and packaging equipment. They are also used in the metalworking sector, in production lines and in machine tools. Their design allows mounting in split or pillow block housings, which simplifies maintenance and replacement in the plant. They are a reliable solution for shafts rotating at moderate speeds with combined radial and axial loads.
To select the correct bearing, take into account the shaft diameter, the load type and the environmental conditions. The KTTB seal protects against dust and moisture, making it suitable for environments with moderate contamination. Check that the housing is compatible with the XGGE series and that the shaft has the appropriate tolerance. During mounting, make sure to align the housing properly and lubricate according to the manufacturer's recommendations. Careful mounting extends the bearing service life and prevents premature failures.
Regarding equivalences, Y-bearing inserts from different brands can be interchanged if the main dimensions match: bore diameter, outer diameter and width. However, suffixes and series letters vary between manufacturers, so it is not advisable to rely on the code alone. It is always recommended to verify the dimensions and operating conditions before replacing one brand with another. At MR Accesorios Industriales we can help you find the right equivalence for your equipment.
