- The rotating spindle is extended right through the tapered shank.
- Two specially designed adjustable needle-roller bearings carry all radial loads.
- A heavy duty ball thrust bearing takes all axial thrust.
- Thermal expansion and shock loads are absorbed by a special compensator spring.
Complete protection of bearings from the ingress of coolant, dirt or swarf is provided by the built-in oil seal, which also prevents loss of lubricant. Create less thermal friction when turning. Thanks to twin, sealed needle-rolling ball-bearings, the 60° center point moves freely with the workpiece being turned to help reduce friction and heat at high speeds. A special compensator ring absorbs thermal expansion and shock to help you achieve precision results.
