Can my block swivel under load?

Can my block swivel under load?

Many blocks have head fittings that can swivel. The standard issue head fitting in most cases is not fitted with a thrust bearing of any kind. These swivel head fittings are designed to allow alignment and proper positioning of blocks during take up only. Do not intentionally swivel a load about a head fitting without a proper bearing, the result will increase wear and possible unscrewing and detaching of the head fitting under load.

To check for the presence of a thrust bearing simply look between the bow and the head fitting nut. A roller bearing should be obvious if a bearing is present. If you are in any doubt call Nobles quoting the test number and we can make a determination based on our records.
