I do read it. As I have understood your point is wether the seal can be changed separately and how much a seal costs vs the cost of a ball bearing. I think it would be nice to hear the opinion of some more people too. I think that since the price of a ball bearing or a seal compared to one hours...

Thankyou for all responce. I think we should clarify that we are not talking bearings sealed to keep dust out, like 2RSR or ZZ. Everybody knows them allready. The picture is just an illustration, it's the standard resemblence of a 6004 bearing as Ironcad makes it modified to have a sealing and...

The difference to a "standard sealed ball bearing" is very big. If I would suggest to my customers to rely on such a solution to keep an essetial part of a machine filled with oil they would fire me. Leffe

Apearently I need to clarify this. So what I want to compare with is not a ballbearing but a ballbearing and a sealing. Compared to a traditional design this shaft can be machined to a rugher surface, (cheaper)the sealing runs against a smother hardened surface (no leak) (less wear)(longer...

Has anyone like me felt the need of a new type of ball/roller - bearing with an integrated sealing. Very often when designing some type of gearbox or other casing with a shaft coming out of it, one needs a sealing to keep the oil on the inside. To do this with a separate sealing makes the design...

I am a mechanical engineer who invented a new pumpgeometry, I need to get some basics aboute how volume and temp varies with pressure. Here I think is a good place to also admit that english isn't my native language and I appologise for spelling errors and for not knowing the correct terms in...

I hope I don't missunderstood your question. As I understod you have a noumber of dies or holes and you whant the coordinates. Set up your part in a milling machine with digital scales and use a dialgauge to find the position of the holes. If you don't have the equipment I guess it's cheaper to...

Thankyou for your reply. Now I know that we are talking aboute 10 - 20 bar pressure. I also didn't know that centrifugal compressors was used in cooling units. You can think of the compressor I have made as a rotor compressor similar to a lysholm screw only "mine" has less internal...

I am an mechanical engineer and have just started tests of a new type of compressor I have invented. I have made a prototype to produce compressed air (10 bar) and it is performing very well. My question here is to try to form an opinion wether this new compressor would be suitable to use for...
