SKF · Bearings & Power Transmission · Roller Chain Sprockets — ANSI
SKF PHS40-1DSA21 ansi roller-chain sprocket (iso / din 8188). Machined-tooth roller-chain sprocket cut to the ANSI B29.1 / ISO 606 / DIN 8188 imperial roller chain series (25, 35, 40, 50, 60, 80, 100, 120, 140, 160, 180, 200, 240). Simplex, duplex or triplex tooth profile per fitted chain execution. Bored for QD taper bushing or pilot-bore. Hardened teeth standard. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options (material, sealing, cage, precision, clearance, lubricant). Genuine SKF supply carries the SKF logo etch or moulded mark and hologram-authenticated packaging.
