SS UCP204 Stainless Steel Pillow Block Bearing 20mm Bore Anti-Corrosion Food Aquatic Conveyor Bearing Unit

1. Product Overview

SS UCP204 is integrated stainless steel pillow block bearing unit, composed of SUC204 stainless steel outer spherical insert bearing and SP204 stainless steel two-bolt vertical housing, inner bore size 20mm. Different from ordinary cast iron UCP204, insert bearing inner ring, outer ring, steel balls, set screws and bearing housing all adopt stainless steel material, excellent resistance to fresh water, salt water, salt fog and weak acid-alkali corrosion.

The insert bearing features spherical outer ring with ±3° self-aligning compensation function to offset installation deflection and shaft machining error. Double set screw locking structure on wide inner ring firmly clamps transmission shaft to prevent sliding during long-time operation. Double-sided composite rubber contact seals block water vapor, food residues and dust, matched with side grease nipple for periodic supplementary lubrication. Pre-filled food-grade waterproof lithium grease inside, whole unit can bear combined radial load and slight bidirectional axial load. Widely used in food processing, aquatic cleaning, coastal conveying, light chemical and outdoor agricultural machinery with frequent water washing and humid working conditions.

2. Technical Specifications

Complete food conveyor installation drawings, light load matching selection guide and long-cycle salt spray anti-corrosion durability test reports can be provided upon customer request.

3. Core Advantages

• Full stainless steel integrated assembly, bearing and housing both anti-rust and anti-corrosion, solve rust failure problem of cast iron bearing units under frequent high-pressure water washing workshop environment.
• Spherical outer ring self-aligning design, automatically compensate assembly offset and shaft bending deformation, avoid local stress concentration and abnormal bearing wear.
• Double set screw locking on widened inner ring, large contact area with shaft, stable positioning, no idle rotation under continuous reciprocating operation of conveying rollers.
• Double-sided multi-layer composite waterproof dust seal, tightly fit inner ring shoulder, isolate cleaning water, food debris and fine particles, prevent internal grease dilution and steel ball oxidation rust.
• External side grease nipple design, convenient regular lubrication without dismounting the whole bearing unit, reduce equipment maintenance downtime.
• Stainless steel housing integral casting forming, high structural rigidity, not easy to deform after long-term vibration operation of conveyor equipment.
• Standard universal mounting dimension, fully interchangeable with carbon steel UCP204 bearing units, directly replace without modifying mounting frame and transmission shaft.
• Comprehensive customized service: P6 high precision upgrade, surface mirror polishing, OEM laser marking on housing surface, neutral export carton moisture-proof packaging, high temperature resistant food-grade grease pre-filling.
