Keel rollers

Post by OftenBlank » Fri Apr 05 2019 19:39

Going to service / replace my keel rollers. Looking for information, should the roller rotate on the spindle, or does the spindle rotate in the support, or is it both? Also, do you guys apply marine grease to the rubber / spindle interface or does that make the rubber swell and eventually stop rotating? Cheers lads.

I don’t know the answer but I do know grease attracts dust and grip, all that road dust can’t be good and besides them rollers only do a few turns per launch so the wear would be very minimal.

Good point about the grit and sand getting stuck in the workings

Roller is very hard rubber, centre hole is slightly larger than the spindle.
Spindle is steel and fixed in position.
To launch the boat the trailer needs to be submerged so water provides the required lubrication.

I replaced, and upgraded all my keel roller spindles and sleeves last season.

All but 1 where seized on the inner steel sleeve so needed to be cut, then have the spindle knocked out.

I replaced the inner sleeve with 3 needle caged bearings (1 in the centre and 1 each end) and shorter sections of SS sleeve. I lubricated them with copper slip instead of grease.

The boat "glides" off the rollers again now.... :thumbs:

Cheers guys. Only one of the three rotates and even that one has lots of friction. Time for a new set me thinks.

Mr Cod :wave: yes considering doing just that. By the time I’ve refurbished this trailer I could have bought a new one with the money :roll: A previous owner welded up the adjustable side supports just to P me off. :shrug:

use urethane rollers mostly, preferably with nylon sleeves grease the shafts lightly never have any problems with sticking rollers they spin on the shafts and the shafts will spin in the bracket holes if needed but if the rollers are spinning on the shaft the shaft will usually stay put

If you have a keelband fitted replace with nylon ones or that other one I cannot spell

If you don't have a keelband fitted replace the rubber ones with new rubber ones as nylon can knock the hell out of the gelcoat.

The steel shaft's are a tight fit in the rubber rollers

Spud AKA Edward PAC is right but he has a conpleatly different trailer and boat than yours.

Cheers Grant. Hopefully I’ll get around to fitting those ‘extra’ bits when all these other things have been sorted. :clap:

I have to take you to task with this Mike because I don't know where you got that from :scratch:

Nearly all standard spine / keel rollers I'v dealt with new and old have to have the spindle drifted in or out.

When the boat is launchd or retrieved not all of the trailer is submerged (unless it is a bunk trailer) so what lubricates the rollers at the front part of the trailer?

What causes the main problem is that boats get left sat on the trailer for months on end sometimes and this creates flat spots on the rollers mate.

Rollers Ive had were just a solid lump of rubber. Not purchased in the UK but in Europe.
Even got a spare somewhere amongst all the other junk err sorry good stuff :smile:
If I can find it I will post a pic.

Sure they must wear out thats why they are so easy and cheap to replace (presumably) these cunning pirates think of everything.

Works tinnies were just pushed around, onto a trailer or the back of an LWB Landrover and stored upside inside a shed (to prevent theft).
Never kept my own boats on dry land for longer than it took me to pressure wash, dry, prep, anti-foul x 2 and service the engine, 3 days total.

Horses for courses I suppose.
