Marine grade 316 stainless steel ball bearings for shafts from 0.125” to 1.0” diameter  A 316 stainless steel bearing with a polyethylene cage


We can supply inch-sized 316 “marine” grade stainless steel ball bearings with polyethylene, PEEK or PTFE cages.  Our 316 stainless steel 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.


316 stainless steel cannot be hardened by heat treatment so this type of bearing is only suitable for low loads and speeds and is semi-precision grade. For the more commonly used 440 grade stainless steel bearings, please see more details on our product page.


Our 316 stainless steel ball bearings in inch sizes are supplied from stock in the UK and are suitable for use in the food or beverage industry and can be re-lubricated with food grade lubricants. Corrosion resistant bearings can also be supplied in plastic or ceramic materials.
