Marine grade 316 stainless steel ball bearings for shafts from 3mm to 50mm diameter
We can supply 316 stainless steel ball bearings with polyethylene, PEEK or PTFE cages. These marine grade bearings are available open or with low friction seals from stock in the UK and are highly resistant to seawater, salt spray and many chemicals. 316 stainless steel bearings are suitable for temperatures up to approximately 500°C if full complement or 260°C with a PEEK or PTFE cage. They can also be used for cryogenic applications down to minus 250°C depending on cage material.
