The bottom blade pulley bearings on my SIP 14" Bandsaw are tightening up.  I have sprayed with WD40 and managed to free them a couple of times but It is time, I think to renew them.  The manual is absolutely no help.  Have any of you replaced the bearings on a similar saw?
Any advice will be much appreciated.

Hi Richard

I have a SIP and haven't changed the bearings.  However, i did contact SIP over another problem and they were very helpful.  I'd give them a call.

Just another thought WD40 tends to dissolve grease - at least it did on my record lathe and I had to replace the bearings!

Cheers Dave

Stop worrying gents!  Problem solved.
 
Thanks Dave - You're quite right, WD40 does dissolve grease but as the bearings were no good it didn't matter.  I just wanted to remove and replace them.  In between posting my plea for help and coming back to the forum I got it sorted.  I 'phoned the nice gentleman at SIP who informed me that what I was doing was thecorrect procedure and gave me the confidence to apply a little more pressure on my bearing puller and BINGO - off it came.
 
New bearings ordered from Simply Bearings - expected here tomorrow.

Glad it's sorted Richard.  I've got a number of SIP products - planer/thicknesser, chip/dust collector and the bandsaw and a scrollsaw.  

All great value for money and the after sales is very good.

Cheers Dave

Excellent choice in using Simply Bearings, also; they offer a superb next-day delivery service at minimal cost. I replaced all the lower bearings (all bearings below the table) on my 12" SIP saw and it's made a considerable difference. The ones I went for were 'rubber sealed', which helps to further keep the dust out.

Hi Gents
Do Simply Bearings carry all makes of tool bearings or just Sip specialists?
 
Cheers

Simply Bearings stock all kinds of bearings for all engineering applications from several manufacturers.  They are not connected with SIP at all.
 
When you search the site for a particular bearing (in my case 6203ZZ) you will get a list of several types and brands of bearing matching that number.  One is usually a "budget" unbranded product.  I would avoid that like the plague!  It is almost certainly a poor copy of proper branded bearings.  I usually go for SKF or FAG brands.  I used these brands during my working days with no problems.
 
SIP make excellent value for money woodworking machinery for the enthusiastic amateur wooodworker - I would not expect professionals to use them.  I would rate them amongst the best of the Far East produced machines.  Unfortunately though, in order to keep costs low, they use Chinese low grade bearings - not good in situations where they are exposed to either dust or water.

Thanks for that Richard. I've made a bookmark just in case I ever need one.

Bearings were standadiized before WWII and were one of the first things to go metric. There are several firms dealing with bearings, pulleys, sprockets etc
 
Yell.com will find them for you
