Hello, my company is constantly exploring alternate bearing materials (largely as a means of boosting catalogue options- there isn’t a specific performance goal in mind). One such material family is leaded bronzes like SAE 660.
I have been opposed to adding leaded products to our catalogue-...
Hello, our company currently specs a 4140 component, induction hardened to 55+ HRC. However, we then apply a corrosion resistant (ZnNi) coating which involves a baking step at 200°C to mitigate hydrogen embrittlement. In doing so, there is a mild annealling effect which decreases the surface...
Hello all,
BS970-1955 lists all mechanical properties for a given steel grade, considering heat treatment processes. For example, it lists UTS and Yield if for a steel if the steel is annealed, normalized, QT, etc.
Is there a standard, textbook, database etc that lists these properties for SAE...
Hello all, I'm looking for a standard and can't confirm that it exists.
ISO 3290 describes the acceptable tolerances of ball bearings themselves (the actual rolling elements). Is there a comparable standard for tapered rolling elements?
I suppose this question first hinges on another:
In general, are a car’s brakes strong enough to lock the wheel?
Given that locking the tire (skidding) is detrimental in terms of stopping distance, and given that a brake system can effectively lock the wheels, is there a benefit to increasing...
Hello, I'm having trouble reconciling the induced axial loading in a TRB as a result of an applied radial loading. "Essentials of Bearing Concepts" provides a formula using the various contact angles, however bearing manufacturers (SKF, NSK, Timken) all use an equation where Fa=0.5/Y*Fr (the 0.5...
Hello,
I'm looking to install a deck to my old brick house- it is not a veneer wall.
Looking at the IRC and DCA6, I can't find any info about attaching a ledger to a true brick wall, just that it is prohibited to attach to a brick veneer.
Am I out of luck here- will I have to make the deck...
Hello, I have a floor joist with an enormous notch on it- much larger that acceptable.
Naturally the corrective course of action is to replace it, however I'm curious to determine if bridging this notch is a viable solution. Based on the notch location, the bridge would need to replace the...
