Usage The mounted Oval 2-hole Flange Bearing Unit SFD with SSB Y-insert is a high-strength, corrosion-resistant solution designed for hygienic and industrial applications. Its compact oval 2-hole flange design enables secure mounting, stable shaft support and reduced vibration in dynamic systems.

Industries

• Food processing — conveyors, slicing machines and food-handling equipment where sanitation and corrosion resistance are critical
• Pharmaceutical — sterile production environments meeting sanitary requirements
• Beverage — bottling, filling and brewing equipment exposed to moisture and chemicals
• Chemical — processing environments involving corrosive substances

Material and construction The SFD flange bearing unit housing is constructed from AISI 304 or AISI 316 stainless steel for outstanding corrosion resistance and easy cleanability. The SSB Y-insert bearing is made from AISI 420 or AISI 440 stainless steel (AISI 440C referenced for bearings) offering enhanced hardness, wear resistance and mechanical strength. Smooth, polished surfaces meet sanitary expectations to prevent bacterial growth and enable easy maintenance in washdown environments.

Y-Insert bearings Y-insert bearings in AISI 420 or AISI 440 stainless steel provide self-aligning capability, reduced friction and extended service life. AISI 420 offers moderate corrosion resistance while AISI 440 provides superior durability for harsh environments.
