Genuine Freud replacement parts insure the perfect fit and best performance from your Freud router bits.
Freud router bits feature superior quality ball bearings. Lubricated with a high temperature lubricant to withstand the stresses of turning at 22,000 RPMs. Shielded to keep out the unwanted wood dust and chips that greatly reduce bearing life.
Single Row Shielded Deep Groove Radial Ball Bearing ,This is a set of 4 ball bearings. A ball bearing is a small metal ball that goes inside the air release valve.
The surface that the balls roll on is ground first, and then lapped. This means that a very fine abrasive slurry is used to polish the races for several hours to get almost a mirror finish. At this point, the races are finished, and ready to be put together with the balls.

These Ball Bearings are made from SAE 52100 Chrome Steel to sustain radial, thrust and combined loads proportionate to the capacities of the small shafts for which they are designed. Especially suitable for use in fractional horsepower motors, small appli Genuine Freud replacement parts insure the perfect fit and best performance from your Freud router bits.

The balls are a little more difficult to make, even though their shape is very simple. Surprisingly, the balls start out as thick wire. This wire is fed from a roll into a machine that cuts off a short piece, and then smashes both ends in toward the middle. This process is called cold heading. Its name comes from the fact that the wire is not.
