R&P Knowledge Hub
A grease cap seals the outer end of the trailer hub, protecting bearings from dirt, moisture, and road debris. Nev-R-Lube style hubs use a sealed cartridge bearing system and require specific cap dimensions for proper fit. An incorrect outside diameter or insertion depth can result in a loose fit or damage to the hub bore. Always measure the hub bore and confirm required cap height before installation.
