Component Specifications

Definition
A specialized rotational bearing designed for Clean-in-Place (CIP) spray ball systems that provides low-friction rotational movement while maintaining seal integrity against cleaning fluids and chemicals. This component supports the spray ball assembly, allowing complete rotational coverage during high-pressure cleaning cycles in sanitary processing environments.
Working Principle
Utilizes precision ball bearings within a sealed housing to reduce rotational friction while maintaining axial and radial load capacity. The bearing allows the spray ball to rotate freely under fluid pressure, ensuring even distribution of cleaning solutions across tank surfaces.
Materials
Stainless steel 316L (AISI 316L) with FDA-compliant seals (EPDM or PTFE), ceramic balls for corrosion resistance, food-grade lubricants.
Technical Parameters
  • OD 52-90 mm
  • IP Rating IP69K
  • Speed Rating 100-500 RPM
  • Bore Diameter 25-50 mm
  • Load Capacity 500-2000 N radial, 300-1200 N axial
  • Pressure Rating Up to 10 bar
  • Temperature Range -20°C to 150°C
Standards
ISO 15242-1, DIN 625-1, 3-A Sanitary Standard 20-27

Frequently Asked Questions

What makes CIP spray ball bearings different from standard industrial bearings?

CIP spray ball bearings feature FDA-compliant materials, enhanced corrosion resistance, sealed designs to prevent fluid ingress, and sanitary finishes that meet 3-A standards for cleanability.

How often should rotational bearings in CIP systems be maintained?

Recommended maintenance intervals are every 6-12 months depending on usage frequency, with lubrication checks every 3 months in high-usage environments.

Can these bearings withstand high-temperature cleaning cycles?

Yes, designed for temperatures up to 150°C to accommodate standard CIP cleaning cycles using hot water and chemical solutions.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
