Recommend me a (moly?) grease - for sealed bearings/gears on rigging components

[dankilb]

We’ve got the mast down and are redoing all the standing rigging. I’ve disassembled our late-80s Pro Furl 420 roller furler and a mechanical, winch handle operated, backstay tensioner (of unknown make).

I now need a suitable grease to reassemble the sealed roller bearings inside the furler (top and bottom for the ProFurl) and the gears and small bearing inside the tensioner. The furler had some thick yellow grease in there and had never been disassembled. The tensioner had some red, slightly translucent grease and had tool marks suggesting it had been serviced before.

I’m presuming I ought to use a grease with some moly ( with all those stainless bearings, gears, threads, etc.)? All I have currently is bog standard (EuroCarParts!) moly as used on car bearings and ‘marine’ plain lithium in the grease gun.

I was picking some other bits up from a local engineering supplier and they had moly greases ranging from £7 (Fuchs Renolit) to £12 (Moly Slip Arvina). Both claim high load/pressure qualities and washout resistance, and specify suitability for bearings.

Any thoughts or recommendations?

TIA!

How sealed are the bearings? If they are sealed with rubber seals and never get wet then the car moly grease should be fine - consider the forces and movement involved in a typical CV joint!

If they aren't properly sealed though, having used car moly grease on my alarm mine in the garden, it tends to wash out after a few months - but my "Waterproof" marine grease has been absolutely fine.

Ah, no - the bearings themselves are open (not sealed). They’re equivalent #16010 ‘deep grooved’ bearings. Know I’ve started shopping for replacements, I see the difference.

But they are sealed ‘for life’ within the furler, behind pressed in lip seals, and without a greasing point built in.

Sounds like I need a special washout resistant moly then.

My mistake in how I'd written my post - I didn't mean about seals on the bearings, but seals on the assembly - it sounds like the bearings are kept dry by the lip seals on the shaft?
Assuming the lip seals work and there's no moisture getting in, then the normal moly grease should be fine - I wasn't thinking about the seals on the bearings themselves as they tend to be sealed for life on the sealed bearings.

Seeing as it's low speed and probably relatively low load compared to what any of these bearings are built for, you'd probably find any grease would do!

I have used these guys before for small amounts of special greases needed for projects:

Just checked and the EuroCarParts TripleQX stuff I’ve already got is lithium based moly, #2. Seems the same basic spec as the other varieties I’ve found so far (inc from the eBay recommendation above ??), so I’ll ponder whether to use that and save some ££ or find a ‘washout resistant’ marine-mentioning variety for peace of mind!
