The SKF SYM TF Y-bearing housed unit is an assembled unit that combines a pillow block housing with a Y-bearing insert. It is used to support rotating shafts in equipment where simple alignment and quick mounting are required. The SYM designation corresponds to the cast iron split plummer block housing, and TF indicates the system used to lock the insert onto the shaft. It is a common solution in low- and medium-demand machines, with accessible maintenance and simple replacement.
The SYM … TF designation reads as follows: SYM identifies the cast iron split plummer block housing, with a flat base and two mounting holes. The number that follows indicates the shaft diameter in inches, expressed in fractions. The TF suffix indicates the type of insert bearing locking: a set screw on the inner ring that locks the insert against the shaft. This combination allows the unit to be mounted and dismounted without special tools, as long as the tightening torque is respected.
In Argentine industry, these housings appear in belt conveyors, bucket elevators, mixers, low-power mills, fans and packaging lines. They are also found in water treatment equipment, food plants and metalworking shops. The advantage of the split plummer block housing is that the base is bolted to the structure and the insert sits inside it, which simplifies replacement when the bearing reaches the end of its service life. It is a frequently maintained part in plants that operate with chain- or belt-driven shafts.
To select the housing, first check the shaft diameter and the type of locking your machine accepts. The TF insert with set screw is suitable for shafts with rotation in a single direction and moderate loads; if there is rotation reversal or axial loads, other locking systems should be evaluated. During mounting, make sure the base rests fully on the structure, without shims that deform the housing. The insert is lubricated at the factory and does not require additional greasing in most cases. Check the alignment of the shaft with the housing and tighten the base screws to the recommended torque.
SKF SYM TF series housings are interchangeable with other brands that make equivalent units, as long as the shaft diameter, center height and base hole spacing match. It is not enough for the part number to be similar: the critical dimensions must be compared. At MR Accesorios Industriales we sell SKF, and we can advise you on the equivalence with the part you are replacing. If you have doubts, send us a photo of the old housing or the shaft and base measurements.
