sadicarnot Posted February 21, 2011 Share #1 Posted February 21, 2011 Here is a link to a new style of lockwasher we are looking at at work. They are better than split washers and nylock nuts. The salesperson has a vibration stand that shows how clamping force goes down with vibration using the other types of locking devices. These Nord-Lock washers actually increase clamping force when they loosen. I have not used them on my bike as of yet but plan on it when Fastenal starts stocking them at work. http://www.nord-lock.com/ Link to comment Share on other sites More sharing options...
RandyR Posted February 21, 2011 Share #2 Posted February 21, 2011 Looks like a good idea for an improved lock washer http://www.nord-lock.com/upload/washers.jpg Link to comment Share on other sites More sharing options...
sadicarnot Posted February 21, 2011 Author Share #3 Posted February 21, 2011 Yeah it was pretty cool, the salesforce has a pretty good demo where they have a vibration rig connected to a computer that measures clamping force. They bolt it up with the various locking devices and you can watch the nuts loosen. At work we are looking at this for a cooling tower application where the bolts keep loosening. Actually I am looking at it. Management is afraid of anything new, no matter how well it may work. So I showed them this, if they don't use it I will not be tightening any bolts in the future.

mlew Posted February 21, 2011 Share #4 Posted February 21, 2011 Not a new idea, I used them on a cooling tower over 15 years ago. Don't remember if they were called the same thing but they look identical. Did not have any problems with loose bearing bolts after installing them.

1 Canuck Posted February 21, 2011 Share #5 Posted February 21, 2011 Great design, but I can see when removing the nut, the stud will loosen or come out as well. But that usually isn't a problem anyway. Link to comment Share on other sites More sharing options...

GaryZ Posted February 21, 2011 Share #7 Posted February 21, 2011 How much? Link to comment Share on other sites More sharing options...
sadicarnot Posted February 21, 2011 Author Share #8 Posted February 21, 2011 I don't know. MSC and Fastenal carry them. Things like this, I usually tell my salesperson that calls on me at work that I have a home project going on and they hook me up. Link to comment Share on other sites More sharing options...
