Magic pill?? If you say so!
The info is there for the reading so that folks can understand it is not just magic. It is a completely different type of grease.
Replacing the bearing every 15,20,30 or even 40K is what you like to do that is fine. Sure it's cheap, A good SKF bearing is $37.00. You can use cheap Japanese or Chinese bearings which run $11-15 and I can guarantee they will need changing even sooner. The problem is your always using the same hydrocarbon grease which can only handle up to 230˚F and is lost through the seals very easy when it reaches these temps.
Krytox on the otherhand can handle 650˚F, uses less grease and is not lost as rapidly through the seals as the hydrocarbon. It bonds to the metal surfaces and can actually run a long time almost dry. It is a very high load bearing grease as well. You can spend roughly $50 on a New SKF bearing with Krytox or $37 each year, while pulling the pulley having the old bearing replaced and doing it over and over each year. I find it to be one less thing to do. I think we have enough to do on our cars than replacing the same old bearing over and over.
Seals on these bearings are simple to remove with the proper seal pullers and seat back in just as simple as they came out with no negative effects.
Dupont does this all the time for customers and never has bearings come back for problems.
Bob. You pay for the bearing, I will pack it for free. If it fails in 1 year or your typical interval for changing these then I will be proven wrong. (of course depending on what made it fail)
If it goes beyond the 1 year then you can pay me for the krytox and just check it every year.
There was another company that was skeptical about it too. It was a printing company that used a smaller bearing similar in size to this one that took a lot of load and heat. They had to replace them all the time. ALMOST every week.
They tested it with Krytox. With there normal interval checks of 1 week, using the Krytox, the bearing was fine. It went from 1 week to 2 from 2 to 3 to 4 and finally checking them every year. So far the bearings have gone about 5 years before they needed to be cleaned and repacked.
From changing these bearings out almost every week to lasting on average of 5 years and only needed to be cleaned and re-packed as opposed to exploding ,replacing the whole bearing and having to stop the press while possible having to produce something on a time line sure saved them.
I don't know about you but I am sure tired of towing due to bearing failure. Also tired of stocking up on bearings to have pressed in again and again!
This stuff has been proven time and time again.
In the very competitive, high-profile world of professional auto racing, cost-effective maintenance of precision automotive components is crucial. Mechanics look for a lubricant that is easy to apply and most certainly offers consistent, reliable quality.
During the 24-hour race at Nürburgring in Germany this year — one of the most popular and most thrilling long-distance racing events in the world — the high-performance lubricant, DuPontTM Krytox®, created a small sensation. A total of 200 vehicles from 29 manufacturers competed in this grueling race, accumulating 500,000 km.
Materials Selected and Why
During earlier trials at the German formula series, the Touring Car series, the Rally series, and numerous other national and international racing events, Krytox® already proved itself as a superior product. The Krytox® reputation prevailed when Jutta Kleinschmidt, also known as the "Dakar Queen," won the Rally Paris-Dakar trophy in 2001and earned second place in 2002. But meaningful results were yet to be realized at the German long-distance series.
Benefits Gained
Although Team Kindler experienced the weakest engine performance in the N3 class in this year’s endurance race at the 24-hour Nürburgring, it qualified starting in seventh position and placed second, just five minutes behind the winning car. While other teams exchanged axle shafts on their identically constructed vehicles as much as three times during the race, Team Kindler nearly completed the race without changing their Krytox®-lubricated axle. A faulty axle cuff necessitated the only exchange, revealing that Krytox® was still present in all smearing places. “Perhaps we would have been able to finish the race with the leaky axle shaft,” Jürgen Kindler summed up. Kindler was quite impressed with the smearing performance of Krytox®.
Anyways, I have been working on this for a long time. We talked about it many years ago as well but I finally decided it is the ONLY way to make these bearings last.
Magic pill or not. I am not saying it will last forever, will need to be repacked and cleaned at some point, but it will not fail and fall apart to leave you stranded. Longevity and Maintenance free is what Dupont assures me of.
I am using DUPONT VERTREL SDG cleaning agent to clean the bearings, seals are simple to remove and are not damaged in anyway doing this, seals POP back in easy, no dirt will be introduced into the bearing due to them soaking in the cleaning agent, dried immediately and packed and sealed within a few minutes, well that and a clean environment to do this in which I have.
Use it or not but it is there if you want to try it. I am offering it since I have to buy a lot of this stuff and it is not cheap. Thought I would share the success.
Chazzy, The saab Bearing is nice. But will suffer the same problem, Hyrdocarbon grease, high temps is the problem. Although quiet. The krytox although used in the OEM metal pulley is super quite now.
I can pack the saab bearings as well if you choose the plastic pulley.
Thanks
