Product Information

Manufacturer: DeWALT, Porter Cable, Black and Decker

Product Number: N110359

Classification: Part

Weight: 0.01 lbs.

Shipping: Ships Worldwide

Description:

This is a genuine OEM replacement part, it is sold individually.
This Ball Bearing is sealed on both sides.

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.

Warning: California's Proposition 65

Bearing failure on DeWalt miter saw

There are thorough videos on YouTube covering this repair so I will leave it to them. If you own or are willing to purchase bearing splitter, this job is a piece of cake. Be aware that DeWalt over tightens the drive belt which is the root cause of premature bearing wear. I was motivated to purchase an OTC bearing splitter set just for this job and was glad that I did. There is some satisfaction is fixing a good tool and returning it to use in this day and age of disposable equipment. Thanks to eReplacement Parts.com for providing these parts for purchase. Fast service and great pricing from a rock solid company. I have purchased parts from them before this and will not hesitate to do so again.

Bearings starting to show signs of failure

Disassembled the Dewalt DWP611 router. Had already received both bearings. During disassembly found that the collet bearing was housed in a plastic insert and held by a plastic gland nut. Gland nut was seized to the aluminum router body and was damaged in the removal. Also the insert which the bearing is seated in will not release the bearing with reasonable force applied. Found the best course of action was to order a new gland nut and insert before proceeding any further with the repair. Would recommend to anyone who is going to replace the bearings order these parts also to be on the safe side. My router has at least 5 hundred hours of use as it is the spindle for my CNC machine.

Bearing and brushes needed replaced

Took the tile saw apart till came to bearings. The screws were corroded so they broke and had to be drilled out and re threaded.
I used all the parts ordered except the screw.
Also was careful to lay the saw parts out in order and followed the schematic drawing copied from E Replacement when putting it back together.
It's working fine but not an easy task.

Great service fast delivery.

I'm a retired business owner in the service and repair business and I have used your company when I couldn't receive parts from the companies that couldn't send parts due to them being out of stock or it would take too much time to send me parts. Anyway now I'm repairing things and decided to give you a call and ordered some parts which were delivered and I was pleased. But the owner of the Dewalt saw also wanted an armature which you had in stock and the price was $100. He asked if I could find one cheaper and unfortunately for your company I ended up getting one for $78 at another source. I'm sure you won't lose any sleep over this or that I caused a financial burden for the company but just to let you know the other company lied to me as far as delivery and availability and I had to call them to find out what was going on..So any parts needed for any future repair I'll be calling you guys !! Thanks again and sorry about the long story.....John Desaulniers

Back up and running!

Dewalt DW708 Miter - Replaced blown out bearing on drive belt side of the motor shaft. Mine was difficult to remove even with a borrowed bearing separator from Auto-zone. It did required some Dremel cuts to weaken the old hubs hold on the shaft. Assembly easy. Also replaced the other small bearing while apart. Runs great now.
