Sorting and Grading Equipment

Sorting and Grading Equipment

Wet grading lines, lift arms, guide rollers, and positioning.

Pumps, Conveyors, and Handling Systems

Pumps, Conveyors, and Handling Systems

Wet handling equipment, conveyor supports, and exposed parts.

Cages, Service Platforms, and Coastal Support Equipment

Cages, Service Platforms, and Coastal Support Equipment

Slow articulation, support structures, and exposed linkages.

Washdown Machinery and Replacement Parts

Washdown Machinery and Replacement Parts

Cleaning cycles, humidity, and non-standard dimensions.

Common problems in aquaculture equipment

Wet service, cleaning, coastal air, and non-standard replacements drive most bearing requests.

Moisture and Washdown

Water, cleaning cycles, and wet residue around bearing seats.

Coastal Air and Salt Spray

Chloride-rich air around exposed equipment and threads.

Rust on Standard Bearing Steel

Staining, seizure, and shorter maintenance intervals.

Maintenance Access Limitations

Cages, platforms, conveyors, and coastal support equipment.

Non-Standard Replacements

Unusual dimensions, custom housings, or imported parts.

Recommended product families

Start with radial bearings, then review nearby motion components exposed to the same environment.

Material selection: 304 vs 316 vs 440C

Different positions need different stainless grades. 304 is still a valid option when exposure is moderate.
