This Ball Bearing has metal shielding on both sides. This is a genuine Dewalt replacement part that 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.

Fixed
Dewalt router suddenly began smoking,and emitting loud grinding noise.
Upon inspection, found top bearing had seized, and ball bearings and dust cover circulating around armature. Replaced bearing after cleanup, easy fix.
Saved alot of money and I can say that I recycle. Multi repeat customer.
Fast delivery, even to Alaska.

Parts Used
1. Removed the End Cap.
2. Carefully searched for pieces of the broken Magnet Ring.
3. I used the Gear/Ball Bearing Puller to removed the Ball Bearing (Is supposed that the Puller help to remove the Ball Bearing without damage it, but that wasn't my case, luckily I bought also a replacement of the ball bearing).
4. I found the inner piece/ring of the magnet ring still mounted, so, I used a flat head screw driver to remove it, this helped me to see what is the right side to put in place the new one.
5. To put in place the new ball bearing I have used a hammer and a socket with the same size of the inner race of the bearing.
6. Then placed again the End Cap.

Tool Type
Reciprocating Saw
Difficulty
Medium
Time
30-60 minutes
Tools Used
Screwdriver, Pliers, Socket set, 5 pound sledge hammer.
Parts Used
Since the original bearing flew apart after I disassembled the motor housing and tested its operation. I cut off the remaining bearing race with my Dremel tool using the cut off disk. I then installed the new bearing using a long socket with a connection size slightly larger than the diameter of the shaft for the bearing. I ensured that the surface of the bearing being driven against was kept flat with a heavy, thick washer so the force did not cause the bearing to come apart. I then used my 5-pound sledgehammer and two pieces of scrap 2 x 4s to protect both ends of the shaft and the long socket.
I used this method since I neither have a small gear/bearing puller nor a press.
