Choosing the Right Tolerance for Bearing Housing Design: A Scientist's Guide

AI Thread Summary
When designing a bearing housing for an axle, understanding the appropriate tolerances for the axle to bearing bore and bearing outer diameter is crucial. The choice of fit—clearance, interference, or transition—depends on the application requirements, with clearance fits being recommended for light duties, especially when using Loctite for assembly. Familiarity with tolerance types from resources like SKF is beneficial, but practical application guidance is still needed. The discussion highlights the importance of selecting the right tolerances to ensure proper function and reliability in the bearing housing design. Clear guidance on tolerances will enhance the overall design process.

I'm currently in the process of designing a bearing housing for an axle. Unfortunately I am not 100% on the diameter of my axle yet but I want to have a clear understanding what tolerances to use on my axle to bearing bore and bearing outer diameter to the bearing housing.

I've looked over the SKF website to familiarise myself with the different types of tolerances however I'm still unsure on how I should pick the right tolerance for my application and also what fit I want to achieve (clearance, interference or transition).

Any help or guidance on what I should be looking at to define this would be very helpful.

Clearance with Loctite is the easiest one to use for light duties and/or where available skills and equipment are limited .

This sounds suitable for my design.

What about considering tolerances?

Thread 'Carburetor cfm rating -- adding more air to intake manifold'

Carburetor CFM A Holley Carb rated at 500 cfm 2 barrel carb has venturi diameter of 1.3/8". There are 2 barrel carbs with 600 cfm and have 1.45 diameter venturi. Looking at the area the 1.378 bore has 5.9 sq. Inch area. The 1.45 dia. has 6.6 sq. inch. 5.9 - 6.6 = 0.70 sq. inch difference. Keeping the 500 cfm carb in place, if I can introduce 0.7 sq inch more area in the intake manifold, will I have the same potential horsepower as a 600 cfm carb provide? Assume I can change jetting to...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
