The SKF SYFWK LTHR housing is an assembly consisting of a pillow block housing and an insert bearing with set screw locking. It is used to mount rotating shafts on fixed structures, allowing the bearing to be aligned and secured without machining the housing. It is a practical solution for belt, chain or coupling drives in industrial equipment. MR Accesorios Industriales supplies this line, with technical advice to choose the correct size.
The designation SYFWK LTHR is read in parts: SYFWK identifies the pillow block housing series with insert bearing and set screw locking; LTHR indicates the sealing and lubrication variant. The examples cover shaft diameters of 20, 25, 30, 35 and 50 mm, where the central number corresponds to the shaft size in millimeters. This nomenclature allows you to quickly identify the size and features of the assembly.
These housings are used in conveyors, belts, elevators, mixers, mills and transmission equipment in food, chemical, cement and aggregate plants. In Argentina they are common in the meat industry, waste treatment plants and packaging lines, where a robust and easy-to-maintain mounting is required. Their pillow block design allows them to be fastened to profiles, beds or metal structures with four bolts.
To select the housing, check the shaft diameter, the expected radial and axial load, and the environmental conditions. The LTHR seal protects against dust and moisture, but if there are frequent washdowns or fine particles, consider additional protection. During assembly, ensure that the base rests completely and that the insert locking screws are tightened to the recommended torque. Lifetime lubrication simplifies maintenance, although in severe environments periodic inspection is advisable.
Regarding equivalences, insert bearing housings from different brands can be interchanged if the main dimensions match: shaft diameter, hole spacing, height to center and locking type. However, always check tolerances and the sealing system, as they may vary between manufacturers. For replacements, the safest approach is to compare the complete designation and the actual housing dimensions.
If you need to replace a housing or assemble new equipment, send us the complete code and quantity via WhatsApp. At MR Accesorios Industriales we help you confirm the correct variant and resolve assembly questions. We can also advise you on alternatives within the SKF line if your application requires a different configuration.
