Description

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 incl. handpiece HA 12 G28.

Recommendations for use

It is essential that the rotational speed and power output do not fall below or exceed the specified ranges.
It is not possible to repair cores and flexible casings. We recommend replacement with pre-assembled new parts.
When using flexible shafts, please ensure that the shafts are not bent beyond the specified radius of curvature. The smallest possible radius of curvature is given for each flexible shaft.
The radius of curvature should not be smaller than 240 mm.
For maintenance of the flexible shaft, PFERD recommends the P-SET BW 10/12 maintenance set with flexible shaft grease FT 4.

Ordering notes

Special lengths available on request.
Cores and hoses with double-sided sliding coupling on request.
