Appliance Specification

Re: Appliance Specification

what size bearings dose this beast have ❓ ❓

Re: Appliance Specification

The rear is about a 6206zz which is much larger than a hotpoint 6205zz front one.

However, on the plus side, the whole front comes off (a-la Hotpoint) so the whole lot is very easily removed. In saying that the bearings are pretty chunky and I wouldn’t expect that to be a major problem. The tank design is very “Zanussi Nexus” with pinned suspension.

A bearing seal is a bearing seal, the problem with bearing failure is not the seal but down to the drum shaft/collar design and spacing. 😉

Re: Appliance Specification

Chris – that is what I wanted to know, but I have to disagree with Martin on this one.

Most, if not all tub bearing failure on washing machines is due to seal failure or wear. The type and size of sealed bearings on most washing machines would usually outlive the other componants if there was no exposure to water.

Also the type of seal is very important. For instance an oil type seal as used in pre WMA Hotpoint usually fails due to premature wear of the seal lip/s. This is due to the shaft running eccentricly in relation to the seal due to play between the shaft and bearing inner. This is why it is crucial in this type of light transition fit to secure the shaft to the inner with a bearing shaft sealant.

Carbon face seals on the other hand are very tolerant to this type of movement but the weakness of these is the detachment of the carbon face from the rubber seal.

The WMA seal as we all know was a disaster, but look at the seal design. Nobody is sure as to whether it was supposed to mate with the shaft, shoulder or both. Have you ever seen anything like this used on a washer before because I hav’nt. Even the Philips or creda that used a small rubber seal mating with a polished stainless washer had a defined sealing point.

Yes it does matter that the seals mate properly with counterfaces etc but if the seal is not up to the job then you will get premature bearing failure.

Re: Appliance Specification

Sorry about this but I have a bit more to add.

The type of seal using the stainless washer which I think might be what Chris refered to as a V wiper seal was an attempt by the designer to marry the good features of the oil seal and the carbon face seal and eliminate the bad. The problem with this design in my opinion was (1) Cost due to complexity (2) The pressure between the seal and its mating surface was highly dependant on the tolerance and fit of the machined parts due to the lack of a spring to ensure a firm contact.

Most manufacturers seem to have reverted to using an oil seal probably due to cost (cheap and low assy costs). It does have one other advantage over the other designs in that it only has two potential leakage points as opposed to three on the others. All in all i think that oil seals are OK. Apart from the wear the other main problem is lubrication. In an engine for instance they recieve adequate lubrication from they oil that they retain. Not so in a w/m where the only lubrication is the water and detergent. This has been helped a little by the use of a double lip seal which is able to retain a small amount of grease between the lips (for as long as it lasts).

I think the reason why some machines that use oil seals have much better bearing life than others is down to better machining, tighter tolerances and better quality control during manufacture and assy. Because this results in a much tighter fit, seal wear is reduced.

To back up my point about bearing failure – how many rear bearings fail as opposed to front even though they are usually smaller. Its always down to water ingress.

IMHO

I promise to shut up now – honest!

Re: Appliance Specification

And….believe it or not they tried to ruin everything this week…

Last Tuesday we were informed that the Manufacturer was mistaken in the triple aaa award, and the spin speed would have to increase to 1600 to qualify.

6 days later we can report that the appliance will now be 1500 spin and will comply to the triple aaa ratings.

It’s a load of Ballo***, but we now have a final spec, nearly 12 months since we ambushed a nice bloke and sprung on him our ideas. It’s unbelievable that this has taken 12 months, what a learning curve.

Still, we are now at the stage where I could do with some orders. Those who spoke to me as I did the training last week, relax, I have yours written down.

We will have ready for distribution on the 1st March 2006, 350 appliances. Going by the demand I have run into I think we will have to canvess your requirements.
So, please check your emails between Xmas and the New Year as we will send you all an order form, this will be for info only, not official, I’m after figures to plan with not tie you into buying.

We are also working on an agreement between ISE and yourselves, this will be ready in the New Year and all agents who have had the training will receive a copy, Sign one and send it back to us, keep one for your records.
The agreement is simply a set of rules between us, but is contractual, anything you are not happy about should be directed at me (07795 485762) where I will explain any item not understood. If you have not had the training yet, be patient, we will get around to you, in plenty of time.

You will have loads of questions but please wait till we do your training, all can answered easily face to face.

We now have guaranteed availability of 1/3 …350; 1/4….350; 1/5….700 appliances.
