Rotating air chucks are ideal for precision turning and cylindrical grinding applications that require close concentricity, squareness, and parallelism tolerances. Variable clamping force enables clamping of thin-walled and other fragile parts with minimal distortion. All models, except the 3-50, feature a coolant or air passage through the center of the chuck.
Chuck Accuracy
- .00005" (0.0012mm) TIR is standard
- .00002" (0.0005mm) TIR is available
Stationary Air Chucks
Stationary air chucks are ideal for milling, drilling, tapping, and other applications requiring a compact self-contained workholding fixture. Air is supplied directly into the side of the chuck body, and the chuck can be mounted directly to the machine table or pallet. Through holes are available on all models.

Long Stroke Air Chucks
Long stroke air chucks feature extended jaw opening for load clearance or to clamp a range of diameters without changing top jaws. Long stroke chucks are available in rotating and stationary configurations. Their high accuracy makes them ideal for clamping headed workpieces for turning, grinding, or milling/drilling applications. Special models with total jaw stroke of .500" (12.7mm), .750" (19.1mm), and 1.000" (24.5mm) are also available. Please call for information.

HST High Speed Air Chucks
HST High Speed Air Chucks feature a titanium chuck body and are actuated by a patented external wedge design that maintains clamping force at high spindle speeds without counterweights. This revolutionary design minimizes the effects of centrifugal force resulting in consistent clamping force throughout the chuck's rpm range.
HST chucks are available in standard, HS, and BP models. The HS models are dynamically balanced and feature MicroCentric's patented NR50 non-rotating air tube system. The NR50 design eliminates vibra tion caused by rotating air at higher spindle speeds, thus enhancing a machine's surface finish, and roundness capability.

Quick Change Chucks
-
The CB-NX series is a low profile dead length design with a reduced diameter nose for maximum tool clearance. The collet is coupled directly to the chuck body and remains fixed as the tapered seat moves forward when the chuck is actuated. The collet remains fixed in the Z axis during clamping and therefore does not create a pull back effect on the bar stock or workpiece.
CB-NX Features
- Low Profile Dead Length design
- Reduced diameter nose and short overall length provides increased tool clearance and maximum utilization of the machine's Z axis
- Radial adjusting screws to true-up tapered collet seat within .0002” (0.005mm)
- Lubricated-for-life design requires minimal maintenance
- All components hardened and precision ground for highest accuracy and long life
- Stop plates, stop housings, and ejectors can be mounted inside the chuck body for chucking applications
-
The ND series models are used for collet sizes 120mm and larger. The collet is coupled directly to the chuck body and remains fixed as the tapered seat moves forward when the chuck is actuated. Since the collet remains fixed in the Z axis during clamping it does not create a pull back effect on the bar stock or workpiece.
CB-ND Features- Dead Length design
- Radial adjusting screws to true-up the chuck assembly within .0002” (0.005mm)
- Lubricated-for-life design requires minimal maintenance
- All components hardened and precision ground for highest accuracy and long life
- Stop plates and stop housings can be mounted inside the chuck body for chucking applications requiring end stops or part ejectors
-
The NS series is a reduced diameter Dead Length design for sub spindles. Similar to ND chucks, the collet is coupled directly to the chuck body and remains fixed as the chuck is actuated. NS chucks also include a provision for mounting stops and ejectors inside the chuck body.
CB-NS Features- Small OD for maximum tool clearance on sub spindles.
- Dead Length design produces no pull back on the workpiece.
- Lubricated-for-life design requires minimal maintenance.
- All components hardened and precision ground for highest accuracy and long life.
- Stop plates and stop housings can be mounted inside the chuck body for applications requiring end stops or ejectors
- Spindle speeds up to 6,000 rpm
-
In the CB-NB series collet chucks, the collet is coupled directly to the draw tube connector. When the draw tube is actuated, the collet is drawn into the tapered seat of the chuck body, efficiently translating draw tube force into maximum clamping force.
CB-NB Features- Pull Back design maximizes the efficiency of the clamping system by concentrating all forces in the direction of the spindle for highest accuracy and greatest overall rigidity
- Low profile OD and short overall length provides increased tool clearance and maximum utilization of the machine's Z axis
- Radial adjusting screws to true-up the chuck assembly within .0002” (0.005mm)
- Lubricated for life design requires minimal maintenance
- All components hardened and precision ground for highest accuracy and long life
-
The CB-NDR is a patented Dead Length design for use with servo stop bar loaders. Unlike conventional dead length collet chucks, the NDR is actuated as the draw tube is drawn toward the machine spindle to prevent the bar from being pushed off the servo stop.
CB-NDR Features- Pull to Close Dead Length design produces no pull back and will not push the bar off the servo stop
- Radial adjusting screws to true-up the chuck assembly within .0002” (0.005mm)
- Lubricated-for-life design requires minimal maintenance
- All components hardened and precision ground for highest accuracy and long life
-
NK series chucks are a pull back design with the added flexibility of being able to mount end stops inside the chuck body for easy conversion from bar to chucking applications. The collet is coupled directly to the draw tube connector. As the draw tube is actuated the collet is drawn into the tapered seat efficiently translating draw tube force into maximum clamping force.
CB-NK Features- Pull Back design maximizes the efficiency of the clamping system by concentrating all forces in the direction of the spindle for highest accuracy and greatest overall rigidity
- Low profile OD and short overall length provides increased tool clearance and maximum utilization of the machine's Z axis
- Radial adjusting screws to true-up the chuck assembly within .0002” (0.005mm)
- Lubricated-for-life design requires minimal maintenance
- All components hardened and precision ground for highest accuracy and long life
- Removable stop plates and stop housings can be mounted inside the chuck body for chucking applications requiring end stops or part ejectors
-
The NRB series is a hydraulically actuated self-contained Pull Back design for non-rotating applications. The collet is coupled to the built-in piston and is drawn into the tapered seat when the chuck is actuated. Part stops can be mounted inside the chuck body.
CB-NRB Features- Self-contained design with built-in cylinder can be hydraulic or pneumatically operated
- Pull Back design maximizes the efficiency of the clamping system by concentrating the chucking force in the direction of the machine table, in addition to drawing the workpiece against the part stop
- Lubricated-for-life design requires minimal maintenance
- All components hardened and precision ground for highest accuracy and long life.
-
The CB-AG series collet chuck is a pull back design with a floating collet seat for machining shafts between centers. Centers or other part locators are mounted in the ID of the chuck. The floating collet seat can also be locked out to clamp parts on-center. Compact OD and short length compared to other compensating chuck designs provides greater rigidity.
CB-AG Features- 1.5mm (.060”) total compensation
- Mounting in ID of chuck body for mounting locating center
- Radial adjusting screws to true-up locating center within .0002” (0.005mm)
- Lubricated-for-life design requires minimal maintenance
- Compact design for greater rigidity
- Collet seat can be locked out for clamping parts on-center
- All components hardened and precision ground for highest accuracy and long life
-
Shafts can be machined complete between centers with MicroCentric's retractable collet chuck. A face driver mounted in the ID of the chuck drives the shaft as it is supported by the tailstock to turn the end of the shaft. When the chuck is actuated the collet moves forward to clamp the turned diameter enabling the OD of the shaft to be machined completed while the end of the shaft is securely clamped.
WSF Features
- Mounting for face driver in ID of chuck assembly
- Radial adjusting screws to true-up chuck assembly within .0002” (0.005mm)
- All components hardened and precision ground for highest accuracy and long life
