ER - TOP CLAMPING NUT DIN 6499 Description: Friction bearing ER nut has a unique two-piece exclusive friction mechanism combining radial and angular self-centering movements. Features: Unique two-piece friction bearing. Radial and angular float for better concentricity. Powerful gripping force 50-100% higher than the standard ER nut due to the friction bearing mechanism. Balanced for higher spindle spin due to unique extractor teeth design. Compact design - general dimensions and size range are the same as the standard nut. Designed for use with sealed collets. Always assemble the collet into the nut before mounting onto the collet chuck. Insertion Procedure: 1. Insert the collet at an angle fitting the two extractor teeth which protrude (A) into the collet's groove (B). 2. Place the two parts on a clean and horizontal work surface. 3. Press down with your thumb on the back end of the collet until it clicks into place (C). B Collet Groove Extractor Teeth Important: Never insert the collet parallel to the extractor ring. Doing this will chip or break the extractor's teeth.When unclamping the nut the collet will self-release from the chuck by means of extractor teeth. Extracting Procedure 1. Align the engraved diamond shape which is on the silver ring (D) with any of the key slots (E) of the nut. 2. Place the nut with the collet facing down on a clean and horizontal work surface. 3. Insert a screwdriver vertically between the nut slots and the collet on the reverse side of the engraved diamond shape (D). 4. Tilt the screwdriver outwards while helping the extraction by pushing the collet's back end in the opposite direction (F). Note: For maximum performance the clamping nut thread and collet taper must be cleaned and oiled before use.
