Timken 308KDDN Deep Groove Radial Ball Bearing

The Timken 308KDDN is a single‑row deep groove radial ball bearing from Timken Fafnir’s 300 Series, built for smooth, low‑friction rotation under primarily radial loads with moderate axial capacity in both directions. Its double‑shielded KDDN closure keeps lubricant in and contaminants out, ships factory‑lubricated for immediate service, and lists a 40 mm bore, 90 mm outside diameter, 23 mm width, ABEC 1 precision, and standard internal clearance (P). Dynamic radial load is 49,375 N (11,100 lbf) with a static radial rating of 26,022 N (5,850 lbf); grease‑lubricated limiting speed is 4,620 rpm and oil‑lubricated speed is 5,380 rpm. Weighing about 0.64 kg, it supports radial loads and moderate axial loads in both directions and is suitable for electric motors, pumps, conveyors, fans, compressors, blowers, gearboxes, and other industrial rotating equipment requiring reliable, long‑life operation.
