Flexible shaft

Flexible shafts consist of three components which can be combined in different ways: the flexible core (SE), the flexible casing (SCH), the handpiece (HA). The flexible core consists of four to ten layers of wire, conforming to DIN 2076, and is specially designed for high-speed clockwise rotation. The coupling is securely press-fitted to the core. After approximately 100 operating hours, the core of the flexible shaft must be re-lubricated. The flexible casing consists of oil-resistant rubber; the interior being a flat steel spiral and the outside being solid rubber. The connection couplings are pressed on firmly and encased in a rubber sheath as reinforcement.;Because of low noise emissions, continuous operation with little fatigue is possible. Exchangeable collets enable a wide range of tools to be mounted. The sliding coupling enables quick handpiece changes. Flexible shaft without handpiece with duplex spring coupling DPF.
