Replacement Nylon Bushing for Gangways (25 mm Deck Base)

This replacement gangway bushing is a critical component of the boarding ramp mounting system on your boat. It is essentially a round plastic socket that is installed flush in the deck or swim platform, serving as the receptacle for the gangway’s pivot pin. Osculati’s part number 42.659.10 is made of high-strength nylon – a material chosen for its ability to withstand heavy loads, its immunity to rust, and its resilience in the marine environment. The bushing features an outer flange of about 80 mm in diameter and a cylindrical inner bore of 25 mm, which matches the standard pin diameter for most passerelles and gangways. In practice, this bushing’s dimensions make it a universal fit for a wide range of gangways that use a 25 mm swivel pin, ensuring broad compatibility.

Role and Benefits: The bushing takes on and distributes the load of the gangway to the deck, while also providing smooth pivoting as people board or disembark. Because it’s made of tough plastic, it prevents the gangway’s metal pin from grinding directly against a metal socket – thus avoiding galling, squeaking, and excessive wear. In essence, the nylon bushing acts as a bearing surface and a cushion between the gangway and the boat. This design prolongs the life of both the gangway pin and the boat’s mounting point, and it contributes to quieter, easier movement.

Over time, bushings like these can wear out (due to friction) or get damaged under extreme strain. Replacing them with new ones is advisable if you notice play (looseness) in the gangway’s connection or difficulty in its movement. Installing a new bushing is relatively straightforward: typically it is secured with screws or bolts through holes in its flange. You’d remove the old bushing (if it’s cracked or worn), clean the recess, and insert the new one – ensuring correct orientation (some have a small drain notch or a specific alignment). The 25 mm bore is precisely sized to snugly fit the gangway pin; if needed, you can apply a bit of marine grease inside for even smoother action.

Osculati provides this replacement part to ensure that even after years of use, you can restore the original safety and functionality of your boarding system. Inexpensive and easy to swap out, a nylon bushing like this is wise to keep as a spare on board – so that in case the old one fails, you won’t be left without a gangway. The 42.659.10 replacement bushing guarantees that your gangway will continue to pivot freely and stay securely mounted, which is crucial for the safe boarding and disembarking of your vessel.
