| Features | |||
| Your choices are... | |||
| Air Purge | Air purge features are used for automatic blow-off of contamination, dust, chips, etc., at or near spindle bearings. | ||

| Coolant Feed | A through-the-spindle coolant feed allows for direct application of coolant to the cutting or grinding operation. | ||
| High Frequency Drive | High frequency drives can drive a spindle at very high speeds. These typically require a separate external frequency converter. | ||
| Linear / Compound Motion | Linear or compound motion options allow spindles to move axially in addition to its rotation. These are common in drilling and other machining operations. | ||
| Liquid Cooled | Liquid cooling allows for high heat dissipation capacity, and can translate into higher speed ratings. | ||

| Specialty Bearings | |||
| Your choices are... | |||
| Air Bearings | Air bearings employ a compressed air supply to provide clearance and allow for rotary motion with no physical contact, while eliminating wear and friction and allowing for high speeds. | ||
| Angular Contact Bearings | Angular contact bearings allow for greater thrust capacity than radial deep groove bearings. They are typically specified for higher compound loading applications. | ||
| Ceramic Hybrid Bearings | A ceramic hybrid bearing is constructed of steel inner and outer rings with ceramic (typically Si3N4) balls in place of steel. These bearings have several advantages over all steel bearings, such as higher speed and acceleration capability, increased stiffness, higher accuracy, lower friction and heat generation, reduced lubrication requirements, low thermal expansion, and extended operating life. Bearings containing all ceramic balls are also nonconductive and are commonly used in electric motor applications. | ||
| Hydrostatic / Hydrodynamic | Hydrostatic bearings employ a positive pressure supply that maintains clearance between the rotating stationary elements. Hydrodynamic bearings are typically low-clearance assemblies that rely on a film of oil (and occasionally air) that develops clearance while the spindle is rotating -- high startup loads must therefore be avoided for hydrodynamic spindles. Both types of spindles feature high stiffness and long bearing life, and are often used for fine machining and finishing. | ||
| Magnetic Bearings | Bearing between the rotating and stationary elements is provided by magnetic field; air gap clearance is typically low. These bearings offer virtually no rolling friction and very long life. | ||
| Roller Bearings | Cylindrical roller elements provide antifriction bearing. They can be lubricated with oil or grease. | ||
| Tapered Roller Bearings | Tapered roller bearings consist of an inner ring (cone), an outer ring (cup), a cage and rollers, which are profiled to distribute the load evenly across the roller. They have high radial and axial (thrust) load capacity at low to intermediate speeds. The thrust load capacity for single row tapered bearings is about 60% of the radial capacity. | ||
| Other | Other unlisted, specialized, or proprietary bearing configuration. | ||
