Jäger High Performance Spindles utilize hybrid ceramic ball bearings. These bearings have standard steel bearing races and are matched with silicon nitride balls. Advantages of hybrid bearings compared with normal spindle bearings are improvement of:

•     Longer service life
•     Reduced wear
•     Low abrasive wear out
•     Low friction coefficient
•     Higher speeds
•     Low heat conductivity
•     Corrosion resistant
•     Non-magnetic
•     Electrically isolating
•     Improved machining accuracy
•     Higher rigidity of bearing arrangement
•     Small thermal expansion
•     Low vibration impulse by ceramic balls

M-Spindles
M-Spindles are high-frequency spindles for high-speed milling, grinding, drilling and engraving for manual operating by hand and special dressing spindles.

Z-Spindles
Z-Spindles are high-frequency machine spindles for high-speed milling, grinding, drilling, and engraving.

In manual tool changes the tool used each case is changed by hand into the Z-Spindle. Tools are clamped through the use of pressure collets or traction collets.

In Z-Spindles pneumatic direct changes uses in each case is changed automatically by a built-in pneumatic cylinder into the Z-Spindle. Tools are clamped through the use of traction collets.

The tool used in Z-Spindles pneumatic taper changes is changed automatically by a built-in pneumatic cylinder into the Z-Spindle. Tools are clamped through the use of WK-tapers, WK-shrinking tapers or HSK-tapers.

SK-Spindles
SK-Spindles are high-frequency machining spindles for high-speed milling, grinding, drilling and engraving. The insertion of the SK-Spindle into a machine tool is made by a taper adapter.

The tool used in manual tool changes is changed by hand into the SK-Spindle. Tools are clamped through the use of pressure collets or HSK-tapers operated manually.

In SK-Spindles pneumatic taper changes, the insertion of the SK-Spindle into a machine tool is made by a taper adapter. The tool used in each case is changed automatically by a built-in pneumatic cylinder into the SK-Spindle. Tools are clamped through the use of WK-tapers, WK-shrinking tapers or HSK-tapers.

Flange Spindles
F-Spindles are high-frequency machine spindles for high-speed milling, grinding, drilling and engraving. Design as Z-Spindles, but with customized flange types.

Chopper Series
The Chopper is a leaner variant of a high-end, Jäger High Performance Spindle. The main aspect taken into consideration in the development of this product was saving manufacturing costs and ultimately, an attractive final price for the customer.

A cleverly thought out basic spindle concept means that various tool clamping systems up to a maximum of 12mm are available to potential customers at a reasonable price – simply and quickly manual, pneumatic or with a taper change – all these can be integrated into the basic body.

Some Chopper-Spindles can be attached without spindle bracket directly to the machine axis using the available T-slots according DIN 650-8. An integrated ventilation system for cooling the spindle means no additional costs for otherwise necessary cooling units.
