SKF 1205ETN9 self-aligning ball bearing type: self-aligning ball bearing Inside Diameter: 25mm Outside Diameter: 52mm Thickness: 15mm Dynamic load ratingCr(kN):14.3kN Static load rating Cor(kN):4kN Lubrication: Oil Preservative Grease lubrication speed (r/min):28000 Lubricating oil speed(r/min):18000 Dimensions: 25x52x15mm/Metric Mass:0.14kg Features: Self-aligning ball bearing has two rows of balls and a common concave spheried raceways in the outer ring. The bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing. It is particularly suitable for applications where considerable shaft deflections or misalignment are to be expected Additions:the self-aligning ball bearing has the lowest friction of allrolling bearings, which enables it to run cooler even at high speeds. With two structures of bore cylindrical or tapered and retainers made of steel sheet or synthetic resins, the bearings are characteristic of their spherically formed outer ring raceways allowing for misalignment within 3 degree deflection between inner ring and outer ring, so as to compensate concentricity and deflection errors. Application:Precision instruments, low noise motors, automobiles, motorcycles, metallurgy, mill, mining, oil, paper making, cement, sugar industry and general machinery.
