- This item may rust in contact with water / paint - not suitable for paint mixing due to risk of rusting when in prolonged contact with liquid -

- NOT for precision engineering applications; NOT hardened

Please note: dimensions are approximate, there is some tolerance on these relatively inexpensive bearings. A sample is measured to ensure they are nominally the size indicated - see picture of bearing in calipers. Expect something in the order of +/-5% - if you require a precise size with no variation please purchase off a supplier that can guarantee this
