For changing out of bicycle hub bearing
On 2016-07-19 17:06:43
Where I bought a mileage unknown of used wheels, originally contain no ordinary rubber shield bearing the hub of the should that contains the metal shield bearings, replace it with this product because it was with badly backlash.
Indeed of NSK, it was precision perfect for cheap.
I tried to open the seal to try, transparency of grease had been appropriate amount enclosed.
Feel you turn by hand smooth. Since the rear side can not put too much hand usually, changing out remains normal. The front side was filled with extreme pressure properties of grease after complete degreasing.
It slightly around is made lightly, but it does not forcibly recommend that replace the grease because almost unchanged.
Is enough too much performance in the commuter wheel.

From now on genuine products to buy person from quitting.
Maintenance parts for the original Mind CNC milling machine
On 2016-02-09 07:05:01
For the replacement of the bearings that are used in the spindle unit, was purchased as a spare.
Manufacturers might be different, but should work without problems because the standard is the same.
It is recommended the product to those who frequently used the CNC milling machine.
The more there is a high rotation, because the bearing balls will wear, will cause or could not shake occurs clean processing of the rotating shaft, a large hole of more provisions or open-distorted hole would open.
If you think working accuracy kana fell, it is better that you exchange as soon as possible.
When removing the bearing in the bearing replacement is recommended that you use a bearing puller.
(I have made a dedicated puller at a low cost, because it does not use only original Mind CNC milling machine and out, you might be better of commercially available.)
As a foil bearing of the vehicle.

I do not use yet, but it is safe because it is NSK products.
