The differences between sealed bearing bits and non-sealed bearing bits

1. Standard Open Roller Bearing

Standard open roller bearings are bearings without a seal. This means that the

bear-ings are open to outside debris, which can enter through the cone.

The advantage of an open bearing bit is that they are usually cheaper. They are

ideal for drilling shallow holes, in the hundreds of feet. If drilling deeper holes

with an open bearing bit you will probably have to pull it out every couple hundred

feet to clean out the debris in the cones to free them up.

2. Air Cool / Air Blast Bearing

Air Blast Bearings are equipped on Air Circulation Bits. These bits have air

passage that supply air to the bearings for cooling and lubricating of the bearing.

and for cleaning of the bearing from the drilling debris.

3. Sealed Journal Bearings

Sealed Journal Bearings have very good durability and wear resistance. Instead

of rollers inside the cone there is a floating bushing.

The bushing is usually made out of special material that is highly resistant to

heat and galling (surface damage) .
