Seaway needle bearings

Hi,
We have just aquired a Capri25 which has a bunch of Seaway blocks and fittings that appear to be constructed with ball bearings , is there any specific maintenance required to keep them in good condition or should we consider changing to more modern harken alternatives?

Umm... do they have needle bearings or ball bearings?? and what are the bearings made of??? You mention both types of bearings...and I'm guessing that the blocks have ball bearings, since I can't think of any blocks made with needle bearings off the top of my head, especially on a boat as small as a Capri 25.

BTW, depending on what you're using the blocks for, ball bearings may not be the best solution. For relatively static lines that are highly loaded, you'll probably want blocks with sleeve bearings, like the Lewmar Synchros. For lines that are under a heavy dynamic load, like sheets, you probably want blocks with ball bearings. Torlon bearings are preferable to stainless steel in most cases, as they're lower maintenance and can't rust.

If the bearings are a brownish color, they're probably torlon, which is a high density plastic designed for use as bearings. The only real maintenance torlon bearings need is rinsing with fresh water occasionally. But, seeing as you're in Missouri, sailing on fresh water, there probably isn't any need to rinse them other than what the lake does for you naturally.

Garhauer makes excellent blocks, which are now the OEM blocks on several brands of boats, including Catalina, and are very reasonably priced.

Welcome to sailnet... I'd highly recommend you read the POST in my signature to help you get the most out of the site.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Hi
Wow, thank you for such a quick response, on closer inspection I think they are made of torlon ( well they have a dark colour,not what you would see if the were stainless).

I rechecked the inscriptions on them it just names SeaWay USA - Needle bearings.

Thank you once again.

If the bearings were stainless steel and clean...they'd be silver in color...like stainless steel...if dirty, they'd be weeping rust...
