31311 Taper Roller Bearing
Size 55 x 120 x 31.5 mm. Single row taper roller bearing by AMB Bearings, Ahmedabad.
The 31311 is a single row metric taper roller bearing from the 31300 series (steep contact angle for high axial load). It has a 55 mm bore, a 120 mm outside diameter and a total width of 31.5 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 31311 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 31311 is a standard ISO number, so the AMB 31311 fits wherever a 31311 from SKF, NBC, Timken, FAG or any other maker is specified.
