Description type self-aligning ball bearing model number 2306ETN9 size 30*72*27mm Material chrome steel rings balls nylon cage mass(kg) 0.5 application Automotive.tractor.construction Machinery.rolling Mill features good quality,low noise,long life service OEM and customized service Brief introduction : Self-aligning Ball Bearing Information: In a self-aligning bearing, the inner ring has two raceways and the outer ring has a single spherical raceway with its center of curvature coincident with the bearing axis. Self-Aligning Double Row Ball Bearings are designed to work in applications where severe misalignment exists whether from mounting or shaft deflection. The concave raceway of the outer ring in combination with two rows of balls operate over a wide range of contact angles. Features of self-aligning ball bearing: 1:Retainer: Brass/Nylon/Steel as your requirement 2:Single direction 3:Restricted tolerances 4:Vibration resistance 5:Suitable for high speed 6:Radial load Product Protection of self-aligning ball bearing: 1. The installation is correct, that affects precision, life, performance. And fill the bearing with lubricant after installation. 2. Don’t allow strong impact, such as hammer striking, transfer roller pressure 3. Use the accurate installation tool, avoid to use cloth kind and short fibers 4. Lubricate the bearing to avoid rust with high quality mineral oil, especially in summer 5. General inspection, such as the surrounding temperature, vibrate, noise inspection 6. Keep bearing cleaning from dirt, dust, pollutant, moisture. 7. Bearing should not be ultra cooled.
