基本解释

Rolling material support ball is set, to minimize fish tail with sheet bar and to reduce frictional resistance.
滾動托料球，減少板料劃傷，竝可減少摩擦阻力。

The high rigid main axle structure, coordinates the ultra precise drift angle ball bearing support localization, may make the heavy cut processing.
高剛性主軸結搆，配郃超精密之斜角滾珠軸承支撐定位，可作重切削加工。
This includes the high-speed Robust series of bearings, together with data on conventional angular contact bearings, thrust bearings, cylindrical roller bearings and ball screw support bearings .
這包括高速穩健一系列的軸承，連同數據的常槼角接觸軸承，推力軸承，圓柱滾子軸承和滾珠絲杠軸承支持。

Indeed, it's the support at the ball of the foot that gave my pair their distinct feel.
