Mounted Oval 2-Hole Flange Bearing Unit SFD with SSA Y-Insert
Usage
The Mounted Oval 2-Hole Flange Bearing Unit SFD with SSA Y-Insert is a high-performance bearing solution designed for hygienic, high-load, and corrosive environments. The oval 2-hole flange bearing design allows for secure mounting in compact spaces, ensuring stable shaft support and vibration reduction. The SSA Y-insert bearing, made from AISI 420 or AISI 440 stainless steel, provides superior hardness, wear resistance, and corrosion protection, making it ideal for applications with high moisture, aggressive chemicals, and extreme loads. Common applications include food production, pharmaceutical processing, and industrial applications requiring maximum hygiene and durability.

Industries

• Food Processing Industry – Conveyors, mixing equipment, cutting machinery; sanitary compliance and resistance to cleaning agents
• Pharmaceutical Industry – Cleanroom environments, preventing contamination and supporting regulatory compliance
• Beverage Industry – Bottling, filling, brewing systems; moisture resistance and corrosion protection
• Chemical Industry – Exceptional chemical resistance for aggressive and corrosive environments

Material and Construction
The SFD flange bearing unit is made from AISI 304 or AISI 316 stainless steel, offering high corrosion resistance and easy cleaning. The SSA Y-insert bearing is crafted from AISI 420 or AISI 440 stainless steel, delivering enhanced hardness, wear resistance, and durability. The smooth, polished housing meets sanitary standards and prevents bacterial growth. Food-grade seals provide maximum contamination protection and suitability for harsh washdown conditions.
