Stainless steel flanged housings
Stainless steel flanged housings are used in the ball bearing unit series listed in:
The units incorporate stainless steel insert bearings filled with a food-grade grease.
The housings cannot be ordered as separate products.
Stainless steel flanged housings are made of cast austenitic stainless steel (AISI 300 series). They are designed for ball bearing flanged units in heavy-duty applications to resist a wide range of chemicals and other treatments used during washdown processes of food and beverage applications. Compared to composite housings for the SKF Food Line, stainless steel housings offer an even higher level of resistance to aggressive washdown chemicals. Stainless steel flanged ball bearing units are particularly well-suited for applications with high speeds, heavy loads, impact loads, and where reliability and minimal maintenance are key factors.
Stainless steel flanged housings have no relubrication feature and are available in two different designs:
F4BSS series (fig. 1)
→ square flange
→ four round bolt holes
F2BSS series (fig. 2)
→ oval flange
→ two round bolt holes
To protect the bearing arrangement at the end of a shaft, and to avoid the possibility of an accident caused by an exposed shaft end, stainless steel ball bearing flanged units are able to accommodate ECW series end covers (fig. 3). End covers are accessories and must be ordered separately. The designations together with the distance A5 that the end cover protrudes from the housing (fig. 4) are listed in the product tables:
- Ball bearing square flanged units
- Ball bearing oval flanged units
The complete assortment of end covers for ball bearing housings and units is listed in the product table.
End covers are made of polypropylene (PP), have good resistance to most chemicals and can withstand operating temperatures up to 100 °C (210 °F). They are mounted by snapping them into the recess of the housing.
