Foursome Ts07-54 Min | Hurleypurley

Unlike traditional jaw or bellows couplings, the Foursome design employs four interlocking radial lobes arranged at 90° intervals. Each lobe pair contains a preloaded elastomer–metal laminate insert. This geometry provides:

Body:
While three-jaw chucks are fast, four-jaw independent chucks (like Hurley Purley’s Foursome series) give you something crucial: control.

With a Foursome, you can:
🔹 Dial in true zero runout for irregular stock
🔹 Clamp square, hex, or asymmetric parts
🔹 Achiege sub-0.01mm concentricity with a DTI

Model TS07-54 Min (if that’s your variant) likely refers to a compact 54mm body – ideal for bench lathes and second-op work. hurleypurley foursome ts07-54 Min

Pro tip: Use a counterweight for high-RPM work on small four-jaws.

Body:
The wait is over. The TS07-54 Min is the newest addition to the Hurley Purley Foursome series. Engineered for tight tolerances and demanding environments, this miniature four-jaw independent chuck delivers:

✅ 0.02mm repeatability (verify actual spec)
✅ 54mm outer diameter – fits compact lathes and dividing heads
✅ Reversible jaws for internal/external gripping
✅ Hardened steel body for vibration damping

Ideal for: watchmaking, micro-turning, medical device prototyping, and small-batch CNC work.

The Hurley/Purley Foursome TS07-54 Min is a precision-engineered modular coupling assembly designed for high-torque, low-backlash drivetrain applications. Originating from the collaborative engineering standards of the Hurley and Purley lineages (notably in bespoke transmission and servo-control systems), this unit is classified under the Foursome series—indicating a four-point symmetrical load distribution mechanism.

The “TS07-54 Min” designation specifies the Torque Series 07, with a 54 mm minimal engagement length (axial stack height when fully compressed), optimized for space-constrained rotary actuators.
