The SKF FYTWK YTH housing is an assembly made up of a cast iron housing and an insert bearing with set screw locking. It is used to support rotating shafts in transmission equipment, especially when simple mounting and good sealing are required. MR Accesorios Industriales carries this line as part of its bearing housing offering, with technical advice to choose the right size.
The FYTWK YTH designation reads as follows: FYTWK identifies the split pillow block housing with insert bearing and sealing, and YTH indicates the insert type with set screw locking and sealing contact. Examples in the series range from FYTWK 1. YTH and FYTWK 1.1/4 YTH, which use inch measurements, to FYTWK 20 YTH, FYTWK 25 YTH, FYTWK 30 YTH and FYTWK 35 YTH, with shaft diameters in millimeters. The final number always refers to the shaft diameter that houses the insert.
These housings appear in conveyors, mixers, mills, packaging belts and process equipment in food, chemical and aggregate plants. In Argentina they are seen in production lines that need an economical support that is easy to replace, especially when the shaft is not precision-made and a mounting with some angular tolerance is sought. They are also used in fans, centrifugal pumps and low-demand machine tools.
To select the housing, first verify the shaft diameter and the type of locking the insert accepts. The YTH seal protects against dust and splashes, but it does not replace a radial shaft seal for immersion. During assembly, align the housing with the shaft and tighten the set screws onto the inner ring of the bearing; poor alignment accelerates insert wear. Lubrication comes from the factory and should be checked according to the duty cycle.
As for equivalents, insert bearing housings from different brands can often be interchanged if the shaft diameter, the type of locking and the housing dimensions match. It is not enough for the code to be similar: you have to compare the foot height, the distance between holes and the sealing system. If you have doubts, send us the measurements or the original code and we will help you find the equivalent part.
