MicroCentric MBS Chucks are ideal for production turning, grinding, and milling applications, as well as clamping delicate workpieces with minimum distortion. MBS chucks require no maintenance and are especially suited to abrasive and highly contaminated environments since there are no exposed moving parts. MBS chucks are available in self-contained and draw tube actuated models.
