30308 Taper Roller Bearing
Size 40 x 90 x 25.25 mm. Single row taper roller bearing by AMB Bearings, Ahmedabad.
The 30308 is a single row metric taper roller bearing from the 30300 series (medium series for heavier loads). It has a 40 mm bore, a 90 mm outside diameter and a total width of 25.25 mm.
A taper roller bearing has two parts: the cone (inner ring with the rollers and cage) and the cup (outer ring). AMB supplies the 30308 as a matched cone and cup set. The tapered rollers carry heavy radial load and axial load in one direction, so these bearings are usually fitted in pairs and set with the right preload.
Taper bearings of this size are used in wheel hubs, differential pinions, gearboxes and axles of cars, jeeps, LCVs, trucks and tractors. The 30308 is a standard ISO number, so the AMB 30308 fits wherever a 30308 from SKF, NBC, Timken, FAG or any other maker is specified.
