Timken 9108KDD-Z6 Shielded Radial Ball Bearing

The Timken 9108KDD-Z6 shielded radial ball bearing is a single-row deep groove bearing from the Fafnir 9100 Series that uses double metal shields (KDD) to resist contaminants while preserving lubrication for long, maintenance-friendly service. It has a 40 mm bore, 68 mm outside diameter, and 15 mm width, with dynamic radial load rating of 4,410 lbf (19,600 N) and static radial load rating of 2,810 lbf (12,500 N); it supports radial loads and moderate axial loads in both directions. Designed for high-speed industrial use, it offers grease-lubricated speeds up to 5,556 rpm and oil-lubricated speeds up to 6,481 rpm and weighs approximately 0.43 lb (0.20 kg). Typical applications include electric motors, pumps, fans, conveyors, machine tools, agricultural equipment, and general industrial machinery, with common replacements SKF 6208-ZZ, NSK 6208ZZ, and NTN 6208ZZ.
