What type of bearing are used to support the spindle on most table saws?

It depends on two main factors. One: Weather the shaft is pulley driven or is it gear driven, there is a high side-thrust being applied to the shaft. The tension on the pulley wheel puts allot of side-thrust on the shaft. and, when the saw is cutting it tends to try to lift itself up over the wood. Thus applying a side-thrust again. \nTwo: How much did you pay for the table saw? This sounds like a smart@ss question but it's probably the most important factor in what the manufacturer actually uses. Use the roller bearings.

"staking" is the process of anchoring the bearing so it doesn't turn with the shaft.\n\nGo to:\n\nwww.nhbb.com/engineering/astro/installation.cfm

If you mean Drill press table?\nOn the left side of the rear colume is a lever, turn counte-clockwiseto loosen, then on the right side is a crank c.w. to highten, c.c.w. to lower

Horizontal and Vertical machining lathes are both used to mill gears.\n\nCheck out these two links for general info on lathes and a company which makes the machines, Giddings & Lewis. Also, info from Falk company which makes Gear Drives for various applications.

roller. a ball bearing will wear out very fast as will a sleve and thrust

If you have a seesaw let's say and you place a 100 Lb weight on one end and push down the other end to raise the weight one foot, your "machine" has done 100 ft-lb of work.  You should expect to get 100 ft-lb of work back out of the machine as the weight drops one foot to its original position.  However, if the bearings at the pivot are let's say badly rusted and you have to push down 200 lbs to rais the 100 lb weight the machine is inefficient and when the 100 lb weight drops again perhaps it exerts only 50 lb force at the other end.  If you divide output by input and multiply by 100%, you can calculate the machine's efficience.  In our examples:\n\n     output/inputx100% = efficiency\n\n     100/100x100% = 100%  (frictionless machine)\n\n     100/200x100% =  50%  (rusty work in)\n\n      50/100x100% =  50%  (rusty work out)

are the Truvativ cranks euro or american. Meaning do the bearings press in or thread in. Generally the first thing to taking the cranks off is loosening just the left side crankarm bolt. This bolt is located at the end of the spindle and generally is a larger 8mm allen bolt. On some occasions you may need to loosen a side pinch bolt as well. Once that is loose you need to remove the arm. Sometimes the arm slides off and other times it doesn't. The best tool to use is a crank arm puller but if that is unavailable you could use a ratchet extension and a hammer. The crank arm puller will thread into the internal threads on the arm and by tightening the crank arm puller you will be pressing the spindle the opposite way forcing the arm off. If you use a bolt and a hammer. be sure to make sure the bolt is large enough to not go inside of the threads of the spindle yet small enough to fit inside the crank arm head. You will just pound towards the spindle and the arm will go the other way, unless of course its a european bottom bracket. In that case you will have to use a crank arm puller because the cups thread in and cannot be pressed out. Once the arm is removed a spanner wrench or a thin screwdriver will take out the threaded european cup if its american and not threaded all you will have to do is tap the cup and bearing out. if you have any questions forward me an email at ashesoverpompeii@yahoo.com

Cutless bearings refer to rubber lined bearings operating with water lubrication on an elasto-hydrodynamic principle. The fluted design of the bearing utilises basis lubrication principles to allow formation of hydrodynamic water wedges at the bearing surfaces by flow of water from the grooves. \n\n\n-- Try link for more info --

Check at a local Sears store, they can get you anything just about.  They once got me two little tiny ratchet pauls for my lawnmower and it worked good as new after that.

Its a mechanical device basically used for turning ,tapering of metal,wooden jobs.It can also be used for threading ,offset turning ,boring and drilling of jobs.

Ideally, nothing ☺\nBut if it's been rebuilt, the ways are reasonable straight and parallel, the bed is flat, and the spindle doesn't wobble, I'd guess around $5K or $6K depending on how many mills, tools, collets, etc. are getting thrown in with it.\n\n\nDoug

Its a machine with an electric motor that produces arcing to provide power drilling with a bit or router, or screwing something in.

In the USA, a good reference for suppliers is the Thomas Register, online at:\nhttp://www.thomasnet.com/\n\nSearch for manufacturers who use your products in their end products (e.g. search for machine tool manufacturers since they use washers, brackets, etc.)\n\nHope this helps!

What kind of spring? There are compression springs, torsion springs, leaf springs--and for what purpose?  Stiff wire wound around a spindle can produce a compression spring. You could use a lathe to cut a groove in the spindle for a certain pitch & wire gauge. Do you need a custom spring? Try googling "wireformers" if you need a spring in any manufacturable quantity. Otherwise, if you aren't sure how much force your spring should have, efunda.com is a good engineer's website--search for "spring" and go from there to develop your specific spring.
