CB-NX Collet Chuck- Dead Length Design
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
CB-ND Collet Chucks – Dead Length Design
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
CB-NB Collet Chucks – Pull Back Design
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
CB-NDR Collet Chucks – Pull to Close Dead Length Design for Servo Stop Bar Loaders
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
CB-NK Collet Chucks – Combination Design
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
CB-NRB Collet Chucks – Stationary Design
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.
Non-rotating dead length designs are quoted on request.
CB-AG Collet Chucks – Compensating Pull Back Design
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
WSF Collet Chucks – Retractable Design
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

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
