The FYWK Y 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 equipment where simple mounting and good sealing are required. The SKF FYWK Y series is characterized by its compact design and its self-aligning capability. MR Accesorios Industriales supplies this line for industrial applications in Argentina.
The designation FYWK Y is read as a series of housings with insert bearing. The letters FYWK identify the housing type and the suffix Y indicates the insert locking system. Examples FYWK 504 Y, FYWK 505 Y, FYWK 506 Y, FYWK 507 Y and FYWK 508 Y show the variation of the number that defines the shaft diameter. The higher that number, the larger the shaft diameter accommodated. The complete part number allows selecting the right unit for each shaft.
These housings are used in conveyors, belts, elevators, mixers, fans and agricultural machinery. In Argentina they are common in food plants, cement plants, quarries and metalworking workshops. Their robust construction withstands environments with dust and moderate humidity. Being sealed units, they simplify maintenance and reduce downtime. They are mounted on flat surfaces with two bolts, which makes installation and replacement easy.
To select the housing, check the shaft diameter and the type of load. The insert with set screw locking requires a shaft with suitable tolerance and a ground surface. Lubrication comes from the factory, but it is advisable to check the condition of the seal if there are contaminants. When mounting, align the housing with the shaft to avoid stress. Tighten the set screws with the appropriate wrench and check the radial clearance. Correct alignment extends bearing life.
SKF FYWK Y housings can be interchanged with units from other manufacturers that follow the same basic dimensions. Equivalent series from other brands usually share the shaft diameter and the distance between holes. However, always verify the exact dimensions before replacing. MR Accesorios Industriales supplies SKF as an official brand, and can advise you on compatibility with other brands. Interchangeability depends on the housing and insert dimensions.
