SKF · Bearings & Power Transmission · Roller Chain Sprockets — Metric
SKF PHS08B-1DSA21 metric roller-chain sprocket (iso / din 8187). Machined-tooth roller-chain sprocket cut to the ISO 606 / DIN 8187 metric roller chain series (04B, 05B, 06B, 08B, 10B, 12B, 16B, 20B, 24B). Simplex, duplex or triplex tooth profile per fitted chain execution. Bored for taper-lock bushing or pilot-bore. Hardened teeth (case-hardened C45E) 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.
