High-Load Capacity Spindle with Built-in Motor

Achieves both high speed performance and high load capacity. Grease lubrication realizes energy saving by reducing compressed air.

Ideal for multitasking machines with both high load capacity and high speed performance. Grease replenishment system contributes to energy consumption reduction.

High-Load Capacity Spindle with Built-in Motor



Built-in motor spindle that combines high-speed performance and high load capacity, ideal for multi-tasking machines.


Low environmental impact, low noise, and maintenance-free due to the grease replenishment system.


The BT40/HSK-A63 uses the largest bearing inner diameter of 80 mm in these taper sizes and optimizes the combination of bearings.
