Anchor Roller Manufacturer

I need to replace/have made, one of our anchor rollers. I have had no luck finding a local manufacturer or any one in the states. This is not an off the shelf roller, we've looked. Krogen will make me one for $118/each which doesn't' sound to bad but I figure I would ask here first. Any ideas? The roller's 3.75"x5"D with a 1" hole for the pin.

Greetings,
Have you considered having one cast in bronze at a foundry? Should never wear out.

If there is a good source for nylon type plastics nearby you might be able to buy a piece and any machine shop will be able to turn one out for you.
About 10 years ago I needed something similar but shorter and was able to find this at a local fab shop: 6" dia. a weird color but it was free it is very hard stuff but not brittle comes in long shafts and is easy to saw drill and machine.


Maybe someone like Graingers Inc or Mcmaster Carr might have something or could tell you where to find it.
good luck

Tap Plastics might be a good source for the stock:

I called Tap Corp. and they don't carry any 5" dia rod. Thanks for the help though.

I have been to several shops and called a manufacturer. The 5" dia is a problem plus it would still have to put in on a lathe. Thanks though.

Have you tried to remove the rod holding the old one in?

I had a similar problem and love nor money could remove the threaded pin holding m roller in. Had to replace the whole unit.

Heat, cold, impact, curse words and gentle loving were all tried, ended up ruining several tools and reputations in the end.

Make sure you CAN replace it before you go through all the trouble finding the part.

Anchor Roller Replacement

Check out Windline.com They offer a replacement wheel which is 5" x 3.4". I don't know what the shaft diameter is but I'm sure it could be drilled out to 1" if it isn't already.

I did yesterday to get the measurements. It actually came out easier than I was expecting. Not something that usually happens. It also showed that both rollers need to be replaced. This is the spare anchor roller. You can see cracks and the UV damage in the upper right. Definitely time to replace.

Thanks for the link. I sent them an email to see if they can make one similar to their 4" x 3.4" but to my dimensions. The 4" x 3.4" has a grove that I would like so that the anchor shank rests in it.

I think Boson supplies carries 5" rollers, maybe even bigger. Here's the link:

When you get a replacement get BLACK and it will last a lot longer.
Most natural plastics will be seriously affected by sun, u.v., The black protects the stuff.

I worry about a set of plastic rollers of tiny diameter when the boat is anchored and surges back , creating a big load on the roller.

Fine if the boat has a low plate with a snubber line tied to the anchor line that relieves most of the load.

Remember the roller is part of a anchor system , not just a quick stow spot for the anchor.

We chose bronze for the roller.

We talked to a foundry who said it would be cheaper to have a machine shop make them. We then looked at the cost of 5" bronze rod for 2 rollers and the material costs are at least ~$400 before the machining costs. Yikes!

So far, UHMW-PE (black), is at the top of the list: 5" x 12" sold rod is ~$63.

That 5" Windline roller looks like your best bet to me. I think you would have to drill out the hole to accept your 1" shaft. You could file or machine a groove, but I'd worry that there wasn't enough material between the groove and the shaft hole.
I may have one in my store. When I get to work I'll take a look and see how thick it will be after drilling it out to 1".

I think that was one of the reasons yours broke, not enough material between the groove and the shaft hole.

L&L: I do a lot of business with a welder down in Stuart, FL that had the material you're looking for the last time I was over there. He machines these things himself. I just left him a message for the estimate. Are you headed for Stuart eventually or are you staying in Jacksonville?
