For reversal, it must first be pulled from the cone in axial direction. A pressure spring holds the handle in both positions. When swung out, it automatically engages again. The cover conceals clamping elements, e.g. countershaft pulleys, as well as protruding and recessed shafts. For mounting, the cover is pushed in by hand. For dismantling, the cover can be raised and taken off by apply- ing moderate pressure in the rim of the cover. see also... • Stainless Steel Countersunk Washers GN 184.5 (for Axial Fixing) → Page 1090 Information • Plastic Technopolymer (Polypropylene PP) - - Reinforced, shock-resistant - - Temperature resistant up to 80 °C - - Black, matte finish • Hub bushing Stainless steel AISI 304 • Cover Plastic, light gray • Retractable handle - - Plastic, Technopolymer (Polyamide PA) - - Black, matte finish - - Retracting mechanism / Spindle Stainless steel AISI 303 • Keyway P9 DIN 6885 Page 1 → Page 2078 • ISO Fundamental Tolerances → Page 2151 • Cross Holes GN 110 → Page 2080 • Plastic Characteristics → Page 2158 • Stainless Steel Characteristics → Page 2166 • RoHS Specification • With safety retractable handle (swiveling) On request 2 Bore code B Without keyway K With keyway 4 Type R With revolving handle iF product design award Original design VDS+IR-SST
