Bearing (for rotating types): Load Capacity 500-5000 N

Q: What maintenance is required for spray ball bearings?

Regular inspection for wear, lubrication with compatible food-grade grease every 6-12 months, and seal replacement when signs of leakage appear.

Q: Can standard bearings be used in spray ball applications?

No, spray ball bearings require specific materials (stainless steel), seals for chemical resistance, and designs that accommodate fluid pressure and cleaning cycles.

Component Specifications

Definition

A specialized bearing designed for rotating spray ball devices in industrial cleaning and coating applications, providing low-friction rotational support while withstanding chemical exposure, temperature variations, and mechanical loads to ensure consistent fluid distribution patterns.

Working Principle

Utilizes rolling elements (balls or rollers) between inner and outer rings to reduce friction during rotation, with seals to prevent contamination and retain lubrication, enabling the spray ball to rotate freely under fluid pressure for uniform surface coverage.

Materials

Stainless steel (AISI 304/316), ceramic balls, PTFE seals, food-grade lubricants
