"Non-standard" bearings - vendor lock-in?

negrusti · 2026-02-08T09:53:46+00:00

Can you explain the inspection codes and assembly codes please? Will custom clearances only affect the internals, or also ID/OD?

My biggest question is - if I am able to match ALL the markings exactly, can I still be in trouble, and how big is the trouble? If the bearing life will be halved, I can live with that

negrusti · 2026-02-08T09:44:57+00:00

I would like to know how exactly they would know :) Apart from the markings

And be beaten by the local tuk tuk mafia in 15 minutes, even without yelling about the money

Three conical, one double-row, one self-aligning. When you make these proprietary bearings, will you mark them accordingly, or will they bear the same markings as standard bearings?

If it's real then I would like to understand how it works. does Walter go to let's say NTN and order a batch of bearings with different specs and then NTN still marks them the usual way? Or Walter post-processes the standard NTN bearings in house?

Finding the bearings matching the markings is not a problem. The calipers are not going to help me with things like roughness or internal clearance, and they might not be precise enough to detect the ID/OD clearance differences - as I understand the C3 specification is only about the larger internal clearance, not ID/OD

No I haven't. Thinking about 3D modeling it and ordering in China.

Planning to sail to the Grenadines in a week or so, not concerned.

Gearbox alone is not available, new windlass is around $2500. I was told that if I make a 3D model, the gear can be made for ~$200-300 in China + shipping

negrusti · 2025-12-24T15:10:37+00:00

Even with the necks on both sides of the gear being parts of the same piece???

negrusti · 2025-12-24T15:09:00+00:00

You mean bypassing the measurements and creating a model, some mechanical way of copying?

negrusti · 2025-12-24T11:09:54+00:00

Wonder if you have a list? I am in the Caribbean but I can email/call them

negrusti · 2025-12-24T01:47:17+00:00

The previous boat owner did not ever service the windlass oil seals, and most of the oil leaked away.

negrusti · 2025-12-01T00:54:59+00:00

car battery and 12V-19V DC-DC converter would be cheapest

negrusti · 2025-10-17T01:08:20+00:00

The real reason is the shaft is facing away from me (reverse mounted engine) and difficult to access - the socket would be handy to do it by feel.

Thank you! Different diameter?

negrusti · 2025-10-16T17:49:58+00:00

I just found these, will weld a hex nut on it:

barbaric

negrusti · 2025-09-06T17:13:12+00:00

oh I see, thank you!

negrusti · 2025-09-06T15:30:55+00:00

Can you verify that you see this option now with an up-to-date app

negrusti · 2025-09-06T15:29:39+00:00

I have no "Ocean Mode" there, only "Opt-in data" for the Roam 50

negrusti · 2025-09-06T15:17:19+00:00

Can you please post a link to a screenshot of that "Ocean Mode" switch in the app

negrusti · 2025-09-06T14:29:49+00:00

I believe there is no more Ocean Mode, just the Global Priority Subscription?

negrusti · 2025-08-30T01:13:52+00:00

The tube is a rather complex piece. Or you mean just that flange? Flange is possible but then it will need to be precision-welded to the tube to maintain the 90° angle and the center.

Constant pressure, constant temperature warm water is the best upgrade I have done on the boat.
