SKF make thousands of different seals for loads of different mechanical applications. The black ones are genuine skf seals, just not low friction. Probably easiest buying through a suspension specialist unless you know how to select the right ones and find part numbers.
I'm looking for an opportunity to design them in to a machine so I can "accidentally" order too many.Transition Patrol - viewtopic.php?f=10017&t=130702350 -
If your after low friction seals, how about the Push ones? http://www.tftuned.com/push-ultra-low-f ... kits/p31250
-
Never considered them or should I say never knew PUSH did them.
Think I have worked out my POA, after doing a lower service on them yesterday and them feeling ultra smooth but still diving etc. And a ride today more noticeable force is needed to break stiction.
I think either the PUSH or SKF (green) low friction seals with the new fox gold fluid are going to be a step in the right direction along with the new FIT4 cartridge. Should be around £200 guesstimation so not bad.
If I still don't like them, then sell and replace. Did try a few last minute bids today on some RS revaluations and some FOX 34s both were 140mm travel but I could reduce this. If they went straight on my bike they would have been a no brainer for the price they sold for. Less than £200 anyway with change for meal for 2 out.
But I have to factor in a new wheel headset.
Might sound stupid but I just adjusted my SAG from 25% down to 20% did a ride to the local shop for a few things on tarmac and pavement so only braking and going down a kerb are involved. And I used a max of 70% travel, seems alot to me? Or does it sound the norm? I forgot to push the sag seal back to the crown that's how I knew.0 -
How they react under braking on tarmac is absolutely meaningless. I could probably bottom mine if I tried. Ideally you want to be getting 90-100% travel on a decent trail ride with no heavy bottoming.Transition Patrol - viewtopic.php?f=10017&t=130702350

Was thinking 90-100% use of travel on trail would be normal, just didn't expect a high percentage of travel on tarmac.
Now SKF of Push seals both seem to cost the same. Thinking the SKF seals from Rush cycles (never dealt with them).
On a side note, what is the difference between oil weights and viscosity. Seems to me a 10wt fork oil would be better but would mean more frequent service intervals compared to a 20wt oil. Is this true or am I misunderstanding oil wt's?0 -
Oil wt refers to its physical characteristics, mostly viscosity but others as well, nothing to do with longevity.
Interestingly the Rockshox 'official' 5Wt oil has a similar viscosity to most 15wt fork oils!
Use oil of a different viscosity and you will have to adjust the damper to suite, use a viscosity that is too different and you may not be able to ever get the damper working right.Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0 -

Thankyou for the info, what if you were to use a different WT in the lowers?0 -
For lubrication? Well if the only change was viscosity then you would add a small amount of friction, but if it had better film strength and had a friction modification pack like the Fox stuff) then friction would probably see a net reduction, wear protection is down to a combination of viscosity and film strength.
I've always used automatic trans fluid (Dexron II) in the past in lowers as it has a very well developed friction reduction package, a viscosity not didimilar to a fork oil and is dirt cheap compared to specialist stuff and I already have a pot in the garage.
The trouble is that an oil has to be developed for it's application, so the ideal oil for one seal and stanchion finish setup will not necessarily be the ideal for another as things like the stanchion surface finish and the seal preload will be different and require different viscosity and film strength. To add I'm not an expert in that field but have quite a lot of experience looking at oils in internal combustion engines and how different oils react in different engines in the different places within the engines (hydraulic bearings, sliding surfaces, rotating seals etc) and broadly the same principles apply.Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0 -
Thanks rookie, oils etc is not my thing.
I am guessing on what you have mentioned I will be fine to continue using Castrol GP synthetic fork oil 10W. Have been using it for a while now for fork lowers and it is smooth but find I need to do the lowers more often as the oil seems to loose its film or ability to stick to the components if that makes sense, I can't think what the correct term is.0 -
My SKF low friction seals are green and cost around £30 at trade cost (I have an SKF account at work) so retail would be around £70ish.
They're not, they're around £30.00 retail.

Unless they're black SKF/Fox low friction seals.
Agree with the Kashima statement though!0 -

Thanks, mind made up now these http://www.rushcycles.co.uk/m49b292s483p5148/SKF-SKF-Fox-32mm-Low-Friction-Seal-Kit/RS_GB with the new 20wt fox gold and the new cartridge.
Mine are just general SKF seals and not the low friction ones.0 -
That's a good price for SKF seals, Fox Gold is a good call as well but only if your installing a FIT cartridge, it's not suitable for EVO/open bath systems.
It's consistency is unlike anything I've ever used or seen, including motor oils, nearest thing to it is gearbox oil. It's very tacky/stringy, I use it in my 2010 36's with Fox/SKF low friction seals and wouldn't hesitate to recommend it over Fox Green.0 -
