I assume you're trying to ask for help for yourself, but you'd need to ask a more complete question to get someone who does know how to do this to give you a useful answer.
To calculate the bearing stress between the timber and the steel washer, you need to know the applied force or load. Once you have the force, divide it by the contact area between the timber and washer, which is the area around the hole. The contact area can be calculated as the outer diameter of the washer minus the diameter of the hole, multiplied by the thickness of the washer. Finally, divide the force by the contact area to find the bearing stress.
If you need replacements, they can be bought at a hardware store. If you mean applications/uses ... bicycle wheels have ball bearings. Lots of rolling objects that move around an axle have either needle bearings or ball bearings or roller bearings.
To calculate the weight of the steel rod, you first need to find the volume using the formula for the volume of a cylinder (V = πr^2h, where r is the radius and h is the height). Then, you can calculate the weight by multiplying the volume by the density of steel, typically around 7850 kg/m^3. Finally, convert the volume into meters before calculating the weight to ensure consistent units.
The thickness required to protect against a 100 lb bomb exploding 50 feet away using solid timber walls would need to be substantial, likely beyond what is practical for standard construction. The blast pressure from a bomb of that size at that distance would be very high, and timber walls alone may not provide adequate protection. Additional blast mitigation measures such as reinforcing the walls with steel or using blast-resistant materials would be necessary.
Ball bearings reduce friction by allowing the wheel to rotate around an axle smoothly. The bearings distribute the load evenly, reducing the amount of friction between the moving parts, which helps the wheel spin freely and with less resistance.
Wheel bearings, main bearings, connecting rod bearings, cam bearings, axle bearings, carrier bearings, pinion bearings and so on, need to be more specific.
DEFINITION OF PLANNING OF TIMBER
Wheel bearings? Axle bearings? Differential carrier bearings? Engine main bearings? Engine rod bearings? Engine cam bearings? Need more info to help you.
They come Krunk K2 bearings!
no
No, sealed bearings do not need to be greased as they are already lubricated and sealed to prevent dirt and debris from entering.
The best way to anchor steel shelving to the floor is with Ramset Dynabolts for concrete floors and Timber Floor Fixing Screws for wooden floors. If the depth is over four times the size of the height then the shelving shouldn't need fixing.
you need to buy bearings and bearing races most times they will come as a set you will also need axle seals and you will need bearing grease
Yes, any skate can take either bearing but you need to have the right type of wheel and spacer per bearing. ie, if you have mini bearings you need mini hub wheels and spacers that fit the mini bearings. If you have standard bearings you need standard hub wheels and spacers that fit the standard bearings.
We need to know which bearings you speak of, there are many.
