Mounted flange bearing unit in stainless steel
The SFB 3-hole one-side flange bearing unit in stainless steel is engineered for hygienic and demanding industrial environments (food, beverage, pharmaceutical, chemical). It combines a stainless steel bearing and housing with a polished finish to facilitate cleaning, corrosion resistance and reduced maintenance.

Advantages

• Adjustable, pre-lubricated AISI 440C stainless steel ball bearing.
• Bearing re-lubrication via AISI 304 stainless steel grease nipple or quick coupler.
• Optional safety cap in polypropylene or AISI 304 stainless steel.
• Optional rotary shaft seal (TC) with extra NBR dust-protection lip and stainless steel spring.

Features

• Stainless steel housings: AISI 304 (AISI 316 option available).
• Stainless steel bearings: AISI 440C (pre-lubricated).
• Stainless steel grease nipples: AISI 304 M6x1mm.
• No surface coating required; hygienic polished finish.
• Operating temperature range: -30°C to +120°C.
• Cap options: Polypropylene or AISI 304 stainless steel.
• Seal material: NBR rubber with stainless steel spring.

Usage
The SFB mounted 3-hole one-side flange bearing unit is designed for high-performance industrial installations requiring secure mounting, corrosion resistance and easy washdown. Its asymmetrical 3-hole design enables stable load distribution and installation in constrained spaces. The unit's self-aligning capability reduces shaft misalignment and vibration, extending equipment service life.

Industries

• Food processing – conveyors, cutting machines, mixers and packaging lines where hygiene and washdown resistance are critical.
• Pharmaceutical – suitable for sterile and contamination-sensitive environments, including cleanrooms.
• Beverage – bottling, filling and brewing equipment requiring moisture and corrosion resistance.
• Chemical – handling equipment exposed to corrosive substances.

Material and Construction
Constructed in AISI 304 (AISI 316 optional) stainless steel for enhanced corrosion resistance to moisture, chemicals and temperature variations. Smooth polished surfaces comply with EHEDG and 3A sanitary recommendations to limit bacterial buildup and simplify cleaning. Food-grade seals and high-quality stainless bearings make the unit suitable for high-pressure washdown environments.
