Which ball bearings for in mast furling.

[Kevban]

Hello,
I had to dismantle the in mast furling but despite my best attempts, I lost some of the ball bearings overboard.
I can see that the bearings are some kind of plastic, but I have no idea what exactly it is.
A quick google has thrown up several options, including torlon, delrin, and nylon.
There’s a big difference in price so I’d like to know which is recommended for this application rather than spending unnecessarily or buying an unsuitable product.

Thanks.

Kevin.

i found my roller reefing bearings all degraded and some had collapsed, that was two years ago i replaced them with polyformaldehyde (solid plastic) ball bearings. works like a new one

I would guess they are Torlon, check with the manufacturer

If white it's delrin, torlon are goldish colour

Mine are white also, I’ll look into ordering some delrin ones. Thanks to everyone who replied.

I’ve no idea, I didn’t notice any markings on it, but will take another look next time I’m on the boat.
