# Bearings for Drilling Machines

## Drilling Machines

Drilling machines perform drilling, countersinking, reaming, and thread cutting. The spindle of a drilling machine operates under significant axial loads from the drill feed and radial loads from tool runout.

## Load Characteristics

- High axial loads from feed
- Radial loads from drill runout
- Impact loads at the start of drilling

## Solutions

Thrust ball bearings and cylindrical roller bearings are used. For deep drilling, bearings with enhanced seals are employed to protect against chips and coolant.
