Utilizing axial force, this sleeve’s inner and outer rings expand and contract, creating a friction-based connection that efficiently transmits torque. Ideal for CNC tools and other industrial machinery, the Z21 sleeve ensures reliable performance even under high-torque conditions. It is compatible with SKT350 and KTR105 tightening sleeves.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey
