Thread: TRA001 router bearings

Good plan......but as sure as you buy THE correct bearings, you can bet your bottom dollar that yours are different from every thing else. (Been down that road before). It would be a lot safer to dismantle get numbers off existing bearings and then do the exercise.
Just to appease my curiosity, how old is the router and where would you have used it most? In a table situation or mostly freehand?
I know we had a Makita trimmer set in a table for end cutting 2mm pvc edging. Those bearings didn't last very long at all. I suspected that they were designed for hand use and couldn't cope with end thrust from "wrong" side.
Please let us know your progress, or even a few tips for us wwhen ours become subject to surgery.

Hi Rod,

The router was bought in late 2003 and has been used pretty exclusively in the table. The only time it's ever used by hand is when I need to use one of it's unique features, such as it's circle cutting jig/fence. I have three other routers for hand work; a 1/4" and a 1/2" plunge plus a 1/2" D handled Makita.

I wouldn't say it's been overworked; I've cut sash mouldings, face mouldings and raised panels with it quite happily but generally it just cuts edge profiles.

Be interested in how you go at "picking them up on the way".Unless you pull the bearings out and match them with a Generic Brand,I would'nt have thought they'd be a shelf item.The only place I've had any success in sourcing spare parts for Triton gear is from the UK.Like a lot of other Triton owners,still waiting to hear the latest goss from Kingchrome. If you look up ToolSparesOnline you'll see an exploded view and parts list that'll give some kind of idea of the task you have ahead.Don't know if this is of much help.Good luck.

The original bearings will likely be some Taiwanese no-name, all I need to do is find an SKF/Timken equivalent. The town where I work has two places I can find bearings off the shelf, or who can order them in if I need to. If the worst comes to the worst there is an SKF dealer here in Bundy who can get them in for my return.

Thanks for reminding me that Toolsparesonline have exploded parts lists; I was thinking to myself I could do with something like that to help with the dismantling proceedure!

Thanks Fred, but I'd already found it. The lower bearing has a different part number so I would expect them to be different sizes, or the lower one to be a radial load only and the upper to be an angular.

Remember that they would be rated beyond 25KRPM, not your average ball race. There is probably an extra letter in the part number or something similar to denote the high speed rating, make sure you end up with a perfect match, not just a close match.
Balls escaping at 25k would be terminal for the router, and posibly the operator.

The most likely bearing sizes listed by SKF all have a version with a speed rating suitable for the router in both deep and angular single row ball.

I've yet to find a bearing that SKF can't match, and in many cases exceed.

Chief Tiff......it does have a certain ring to it. Your machine sounds like it is as old as mine. Yours may have done a little more work than mine though. I love bearings! Well I love the engineering and how hard they work and how they can go for so long doing what they do. And when they have had enough they are cheaper to buy than the labour to pull them out and replace them. The world would not be the same with out bearings (with philosophical sigh)

Parts list/exploded diagram is also available on the Triton site.

Ooooh... it's only been nearly a month and today I finally got off my bum and stripped the router to replace the bearings. For those considering doing the same the original bearings were NACHI 6201NKE and 6200NKE. I've just bought a set of NTN's to replace them; they are 6200LLB/2AS and 6201LLB/2AS. $26.40 (ouch!) from my local CBC dealership. If I looked harder or online I could have probably halved that at least....but then again it has taken me this long to get this far!


For stripping the router I found this by Ray Girling.....very informative.
