Versatility is the key to the Xpandrel advantage.
With a variety of End Conditions (EC)
& available Actuation Methods (AM),
we can help you select a configuration that best suits your application needs.

Give us a call, we can work together with you to develop a custom Xpandrel to meet your most challenging needs.
Standard (S) – Flush end with single screw actuation inside center. Expansion slits are inset from each end approx 1” (2” for the 5000 series)
Extended (E)– (1000,3000,4000 series) The total body length is 2” longer than the standard end and the expansion slits are offset, giving a 3” solid end length for chucking & colleting.
(5000 series) The end cap for the modular frame is not flush with the shell body this can be extended and shaped into numerous configurations regardless of the mandrel working diameter.
Flanged (F) – (1000,3000,4000 series) Aside from being extended, an additional 1”-
(2000 Series) Flanged side single actuation is standard.
(5000 Series) Flanged Side actuation is common as these Xpandrels are often heavy and left in the jaws while loading & unloading parts.
Mounting Plate (P) – (5000 Series) Commonly used on this series for plate mount applications. We can make a plate to your mounting specification.
(1000,3000,4000 series) Plates are available keep in mind the OD of the plate will be the starting stock size for the Xpandrel and the body diameter will be turned down from the plate OD we do not fasten plates to an Xpandrel body the plate is integral in these series.
(2000 Series) Flanged side single actuation is standard.
Morse Taper (M) – All series can have a Morse taper drive end if the size and actuation method will permit. For smaller Xpandrels we add a extended flanged end and machine the taper from this extra material
Blind End (B) – (2000 Series) Specifically designed for smaller blind end parts
(5000 Series) Customizable to meet your larger blind end applications.
(1000,3000,4000 series) If your design falls outside of the versatile 5000/2000 ranges, we can work with you within these series to meet your more challenging needs.
Both Ends Single (BS) – This is the standard design for all series except 2000 & 4000. A screw actuator is located inside each center and manually activates a single expansion on the corresponding side of the Xpandrel working area.
Single End Single (ES) -
Both Ends Dual (BD) – This is the standard design for the 4000 series. A screw actuator inside a larger screw actuator is located inside each center and manually and independently activates two expansion areas on that side of the Xpandrel working area.
Single End Dual (ED) -
Side Single (FS) – This design uses a screw plunger on the side of the Xpandrel to axially move a piston which expands a single area. On smaller Xpandrels this option requires a flanged area to provide a platform for the screw plunger
Side Dual (FD) – This design uses a screw plunger on the side of the Xpandrel to axially move a piston to activate two areas of expansion. The expansion activator in this case is not independently controlled therefore this method uses high precision machining and very tight tolerances to maintain equal expansion rates.
Combinations – The possible combinations of end, side and dual actuation make the Xpandrel flexible enough to handle most work holding needs.
Combo Single (CS) – Single side actuator and single end actuator.
Combo Dual (CD) – Dual side actuator and dual end actuator.
Combo Single Dual (DE) – Single side actuator with dual end actuators
Combo Dual Single (DS) – Dual side actuator with single end actuator.
