Description:
This is a Genuine OEM Approved replacement part used on Bosch Miter Saws. This Ball Bearing allows for the Armature to spin freely. This part is made out of Metal and it is Sold Individually. Ball Bearings are used to reduce friction between rotating parts. The balls or rollers take the load and spin, distributing the weight evenly while the minimal contact area of the ball reduces friction. This reduces wear on the tool and allows it to run smoothly. Bearings experience constant wear when the tool is in operation from pressure, heat, vibration and friction. Because of this, many Bearings need periodic maintenance or replacement.

To replace this Bearing you would need a Screwdriver and Pliers.

Can you provide me with dimension of bearing, standard, and calculation of bearing life?
Yazeed for model number 0505314888
Hello Yazeed, Thank you for the question. The bearing is just over 1 inch in diameter but unfortunately we do not have the standard, and calculation of bearing life. For more specialized assistance or to speak with someone about this, I would suggest calling the manufacturer of the appliance directly. Hope this helps!

Motor bearings worn out
1.) Bosch 4000 Table Saw w gravity rise stand. Removed blade and then table saw from stand (4 bolts)
2.) Turned table saw upside down and removed plastic table support frame from cast table to access motor (4 allen-head cap screws & 2 small bolts).
3.) Removed brushes (2)
4.) Removed motor end cap (3 screws) to expose rear motor bearing and wiring to motor field
5.) Removed motor housing from cast gear box/blade support (4 screws). Armature remained in gear box.
6.) Removed armature by pulling out of gear box and front bearing
7.) Removed front bearing retainer (2 screws) and removed bearing with inside puller. Replaced with new bearing and re-attached retainer.
8.) Removed rear bearing by cutting off with dremel and cutting wheel. The outer bearing had fallen off with ball bearings so only inner race remained on armature shaft and nothing for puller to grab to...so had to cut off.
9.) Replaced new bearing on shaft and cleaned armature with damp rag and a little brake cleaner.
10.) Removed wire nut caps from field wiring and rear motor cap (which contains speed control board). Removed 2 bolts that held field in motor housing. Removed field from motor housing by tapping out from rear.
11.) Replace with new field. Reattached wire nuts and tightened 2 bolts.
12.) Added grease to armature shaft gear end and reinstalled cast gear housing/blade support.
13.) Reassembled saw in reverse order
14.) Replaced saw blade
15.) Plugged in and ran like new. Parts for $100 saved my $600 table saw. Tool retailers wanted $300 minimum to begin repair which would be used towards the final repair bill. Glad I did it myself, but you should have some mechanical and electric motor knowledge and able to keep parts in order during disassembly.

Front Bearing in motor blew up. I replaced both bearing even though there was nothing wrong with the rear bearing.
1, Removed end cap from motor
2. Remove outer plastic case.
3. Removed plastic blade housing cover.
4. Removed front metal gear assembly cover.
5. Removed Armature from gear housing.
6. Used bearing puller to remove front bearing
7 Used Large 1/2 drive socket to install new bearing
8 Removed & replaced front rubber ring seal
9. Remove and replace rear bearing.
10. Cleaned gears and housing.
11. Repacked axle grease around gears, bearing and inside housing
12. Reassembled in the reverse order.

Note: The hardest part of this is reinstalling the two screws that hold the armature assembly to the front gear housing. There is a metal plate that the two screws that go through the housing into the metal plate on top of the armature. That plate is free-floating and there is about a 1/4" of clearance between the housing and the plate and the top of the armature assembly. Gravity is your enemy trying to get the plate and the screw to line up because there is NO room to put a screwdriver tip or anything inside the space. I tried for over an hour to get one of the screws started again with no success. Finally I went to my screw bin and found a 2" screw the same size and thread pattern as the original and use my scratch awl to line up one side of the plate to the hole. I use the long screw in the opposite side of the plate to temporarily screw it in and bring the plate to the top, where it was supposed to be, then removed the scratch awl, and put in one of the original screws and tightened it. Then I was able to remove the long screw and put the other original screw in the other side. After that was done I tightened both of the original screws and and rest took about 15 minutes. Maybe this will help someone else in doing this bearing replacement?
This repair was on a Bosch Model 4100 table saw, which by the way is a GREAT saw!

Table Saw
Parts Used:
Bearing - 2610911927
Repair Difficulty:
Hard
Time Spent Repairing:
1-2 hours
Tools Used:
Screwdriver, Socket set, Wrench Set, jaw puller
One of two bearings seized up
Disassemble until you can get to the bearings to remove. Print out the parts schematic available from ereplacementparts.com, and have it handy when it is time to reassemble. The bearings are difficult to remove without the jaw puller, so if you do not have one, purchase one or take the electric motor to you favorite mechanic to have them removed.

Worn out front bearing, Bosch series 4000 table saw motor
1. Separate chassis from table top for easier access to motor. (four corner screws)
2. Pull spring loaded shaft locking plate (two screws)
3. Pull transmission (four screws)
4. Release plate that holds front ball bearing to motor mount (two screws)
5. Pull motor body from mount. (four screws)
6. Pull front bearing off armature with 3/4" ball joint puller purchased at Harbor Freight.
7. Mount new bearing to motor mount.
8. Mount motor. (compression of the four screws will push armature shaft through tight bearing aperture
Greatest difficulty: Remounting the spring on the shaft locking plate. Requires some finesses utilizing a bit of very thin wire fished over the back of the semi-secured plate to pull one arm of the spring up into tension position.

Bearing - 2610911927
Rubber Ring - 2610996948
Repair Difficulty:
Medium
Time Spent Repairing:
1-2 hours
Tools Used:
Screwdriver, press to press bearings
Noisy when running
1. Disconnected the power cord.
2. Upended the saw onto its rear.
3. Cleaned all sawdust from the saw's work area.
4. Tilted the blade the full 45 degrees to access the motor housing screws.
5. Removed three screws and pulled the housing cap off.
6. Disconnected the three wires (be careful to reconnect them properly later AND I had to get three new wire nuts).
7. Removed the four screws holding the housing the pulled off the housing (the field wiring comes with it).
8. Removed old rubber ring, installed new ring and put the new bearing in the rubber ring.
9. Now for the armature. It's exposed with the old tail bearing still on it. The front bearing had to be gently forced out. I used a "fork" (as used in separating tie rod joints) and with that under the tail bearing tapped gently on its edge. Took a lot of taps but was easy and the armature came out of the front bearing.
10. NOW, the front bearing is retained with two screws which must be removed from the saw blade side of the mechanism. They are DIFFICULT to see (blow off all the sawdust! (Remove the blade, the blade lock mechanism and it's two screws).
11. Now you can see the two screws for the bearing retainer. Remove them and the retainer will fall off the other side.
12. Now remove the front bearing. It's easy but you will need a tool of some kind to hook from inside the bearing (like an automotive pilot bearing puller).
13. Now, make sure all the reassembly areas and parts are CLEAN. Clean the grease from the one gear inside the front bearing area and put in clean grease ( the modest amount).
14. I used an automotive ball joint press (portable one) to press on the bearings. They can be tapped (but one runs the risk of ruining one) Now, if you tap, tap on the bearing inner race if you are installing a shaft BUT tap on the bearing outer race if you are installing in a housing (i.e. tap on the race of the bearing where the friction is). A large c clamp will do it (huge). A shop press is better. But, I could not access the installation of the armature into the front bearing (no space).
15. Reassemble as disassembled. Now be careful. You probably better put the bearing retainer on following the installation of the bearing or you will have a modest amount of heartburn if you try to hold it in proper position through the fan. AND, by the way. the fan is delicate. Don't even touch it, if you can avoid it!

Now that was my successful technique and I hope I left nothing out. There is any number of methods to do all this. Good luck.
