We are not aware of any specs that give a specific gap dimension that would dictate removing these swivels from service, but this 10% of original dimension should be a guide.
Annual maintenance: Wear of load bearing parts must not exceed 10 % of original dimensions. Rotate the swivel in both directions while loaded by approximately 5% of max working load limit. The swivel should rotate easily. If not or if the sealing is suspected to be damaged the swivel should be dismounted and inspected. Lubrication is carried out by dismounting xxxx (B) and mounting a grease xxxx . Add grease until grease appears between house and shank and remount xxxx (B).
