Land Roller Wooden Bearings

[Landy Nick]

I did read this as Land Rover Wooden Bearings

Same here lol

I have a chess board made totally from Lignum Vitae. Did help having a father who made bearings out of the wood for ship propellors. Unfortunately the sawdust was so fine it actually killed him at the age of 50.

I bodged up a couple of steel ones 20 odd years ago as a temporary fix. the angle iron cross beams of the lecky poles is just right for the job

just fitted new ones on are twose roller. Malpas tractors were best price. about £25 i think they were.

Malpas Denbigh are generally very helpful and can give competitive prices on most goods. Pity their tractors are blue, and not red and grey like those lovely tractors Emyr Evans have adorning their yard.

That aside, in my experience Malpas Tractors will always go out of their way to help you.

Are these wooden bearings? I'm sick of my Fleming 16 foot roller wooden bearings not lasting. Would be interested in trying nylon maybe if there is such a thing?

Well, I heard beech was best. It is softer than most of the alternatives suggested but it will soak up oil. Then grease every time before use.This certainly sounds like a job that needs a harder wood, but I wonder if that is so? Brass bearings are often preferred to steel. Maybe someone can explain the physics? Friction?

Unless everything is lined up square and true, it's a bit much to expect grease to find it's way from the nipple, through the block and down to the bearing IMO. I take it apart after every 20 acres and smear some on by hand.
I made this a few weeks ago...2 bits of 3x8 bolted together....currently socking in oil. Timber type...unknown.
As yet, untested.

Interesting paper here for folk wishing to make their own, but I notice they don't mention Maple as a good wood but do mention Oak despite it's corrosive characteristics .

Would you not drill a hole from the nipple to the bearing surface?

They come with one ready drilled. Grease gets squeezed out everywhere, and refuses to go down the hole, I've found.

If the hole is at the top, the frame is pressing down to block it.

we made new ones couple years ago out of a short sleeper that is bolted across bottom of electric poles, cut it to size with chainsaw, then drilled hole to suit shaft with 1 of these,

after drilling the grease nipple hole I put a plastic bit of a hammer fixing, 1of the hard plastic ones to act as a funnel for the grease, still seems to work ok

 

[RWG Contracts]

Last lot I made for dad where out of oak, then drilled a hole straight down it for grease nipple.

keruing is a naturally oily wood though so maybe that might be better

 

[CJay]

Why not use an ordinary flange mounted/pillow block ball bearing instead?

 

[joe soapy]

Well my plain steel bearings have now done over 20 years, just oil them when i think about it.
Just 2 bits of heavy angle welded into a square roughly the size of the shaft.
Was only done as a temporary measure to finish rolling the field

We put nylon blocks in a grays roller did the job fine but you had to grease them a lot more regularly or it started to squeak at least the wood takes lube into it.

Remember being told that beech was the preferred timber for bearings .Not sure if this due to it's ability to soak up oil or the fact the wearing surface polishes and seems to 'harden'.

If the grease is squirting out between the frame and the wooden block, make a gasket out of a rectangle of inner tube. Sand the block flat and hammer the frame straight, too.

How do you calculate the weight of a water filled roller if filled up fully. The roller is 8ft. wide by 24".
