SKF UC309 — Insert bearing (YAR / YET / YSA / YEL)
SKF · Bearings & Power Transmission · Insert Bearings
SKF UC309 insert bearing (yar / yet / ysa / yel). Spherical-outer-ring insert ball bearing suited to drop-in mounting in a pillow-block, flanged, take-up or tapped-base housing. Set-screw (YAR), eccentric locking collar (YET), adapter-sleeve (YSA), or grub-screw double-lock (YEL) shaft attachment per suffix. Sealed for life with grease; regreasable variants add a lubrication nipple to the outer ring. 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. Shaft bore diameter 150 mm per ISO 3228 boundary plan.
