In this sector, hygiene, corrosion resistance, and cleanability are paramount. Pillow block bearings are used in washers, fillers, labelers, and packaging machines, often constructed from stainless steel (AISI 304 or 316) for both the housing and bearing insert. They feature specialized, non-toxic seals made from FDA-compliant materials like nitrile or PTFE to withstand frequent, high-pressure washdowns with caustic cleaning agents and steam. Their smooth, crevice-free surfaces prevent bacterial growth and facilitate easy cleaning. Designs often include grease purging systems to flush out old lubricant and contaminants. The ability to handle moderate speeds and loads while meeting stringent sanitary standards makes stainless steel pillow blocks essential for preventing product contamination and ensuring compliance with global food safety regulations, thereby safeguarding both public health and brand reputation.
