SKF · Bearings & Power Transmission · Timing Belt Pulleys
SKF PHP21-T5-15RSB timing belt pulley (synchronous sprocket). Steel or aluminium synchronous drive pulley cut to match a paired timing-belt tooth profile — MXL, XL, L, H, XH, HTD 3M / 5M / 8M / 14M, Poly Chain GT 8MGT / 14MGT. Flanged or unflanged. Bored for taper bushing or supplied pilot-bore for final machining. Dimensioned to ISO 5296 / DIN 7721. 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.
