SKF KDN.KC042AR0 — Thin-section ball bearing (Reali-Slim)
SKF · Bearings & Power Transmission · Thin-Section Bearings
SKF KDN.KC042AR0 thin-section ball bearing (reali-slim). Constant-cross-section thin-section ball bearing (Reali-Slim / Kaydon KA / KB / KC / KD / KG series equivalent) where the cross-section thickness stays constant regardless of bore size, allowing large-bore compact designs in gimbals, robotics, medical imaging and satellite antenna slew rings. 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.
