Bearings for rolling pin.
I’ve had a very delicate commission put to me.
I’ve been asked to make a rolling pin for the iron palace kitchen.
I’ve suggested we go with rotating handles(ie the roll rolls while the handles don’t)
Do I need to, or should I go with food grade bearings.?
Or ,can I just pop over to the local bearing shop and just grab something I think will work.?
Cheers Matt,

I’m curious.
Whats your basic construction - any rough drawings, materials etc.?
I have seen one that the roller was stainless steel and another that was marble then of course the regular timber.
The problem I see is how is the rolling pin going to be cleaned? If just a wipe over, sealed bearing should be fine but, in an industrial dishwasher, it’s anyones guess. Will it be able to be dismantled for cleaning if it’s of complex construction?
Just some thoughts.

Matt, if was going into a kitchen in my family I would just do wood in contact with wood.
But, as it is going into a business that serves food to customers then I would take the high road and deliver the safest solution, which would be a bearing that keeps food out and can be regularly washed without contamination issues. As I understand it, the standard solution would be a sealed bearing made of food grade SS packed with food safe grease. That way you are delivering a food industry standard product that will avoid, or at least minimise, any come back.
Should you go with a bronze bush make sure that it is lead free.
Having said that, the chances of the bearing coming on contact with food is minimal, but you never know with some people. So, I would make the bearing area accessible for cleaning should food work its way into that area. At least that way the bearing area can be kept hygienic, ie, if they ever bother to thoroughly clean it.Stay sharp and stay safe!

I would go with a single end threaded SS rod epoxy glued into one wooden handle and a SS nut glued into the other handle and SS washer between each. That way you can take take it all apart and clean. it.

Was rolling pin with bearings specified? Most chefs in my experience prefer solid rolling pins.

Simplicity,
I would use a stainless steel rod through a hole bored in the wood roller. I would make the hole 1/8 inch larger than the rod, plug one end and fill with food grade mineral oil - from your drug store, used as a laxative - let soak for a week or so, let drain and assemble. Rubbing the handles and roller with mineral oil will make it somewhat water repellent and less sticky to dough.
An aside, wood bearings:

Hi Matt
unless Sal is familiar with using a rolling pin with rotating handles, I'd say don't.
I find that most of the time, the handles on a rolling pin are used with an open hand. It's the palm that does most of the work. The handles only come into play when the rolling pin is used as a weapon. As in "hit 'im on the head."
Many (most?) pastry chefs prefer rolling pins without handles.regards from Alberta, Canada

As a different approach, if you have a rolling pin with simple parallel handles, could you just slip a piece of pvc pipe loosely over the handles? Simple, cheap, easy to clean, reversible...

OK, got that wrong.... : ~}
A shipping container home, very interesting! Seen them on TV programs like Grand Designs, but not known of anyone who lives in one.
I presume that your good lady already has a fixed handle rolling pin that is not ideal for her, so your next step is to try a free wheeling handle design to see if that is better. I understand the project now.
The SS Rod solution proposed by Bob & Paul seems like the easiest solution. I presume you have access to some metal threading dies.
As I have some wood thread cutters I would probably go that way myself and use a large enough diameter that would allow a small diameter bottle brush to clean the bore out from time to time.
With both SS and wooden shaft options, bore first and then turn outside of pin on that 'new' centre. Wood rarely bores straight!
And, as Paul recommends, finish with pharmacy grade mineral oil.
Photos of the finished job and a user report are expected... : ~)Stay sharp and stay safe!
