The TIMKEN AS series tapered roller bearing cup is the removable outer ring of a tapered roller bearing. It is press-fitted into the housing and forms the raceway for the cones and rollers. It is used in equipment with combined radial and axial loads, and where bearing clearance must be adjusted during assembly. MR Accesorios Industriales supplies it in Buenos Aires, Argentina, and advises you on choosing the correct cup according to the part number.

The AS series designation is read from the base number that identifies each cup: 393AS, 394AS, 453AS, 592AS and 3927AS are examples of this nomenclature. The AS suffix distinguishes this variant within the TIMKEN catalog. Each part number refers to a cup with its own outside diameter, width and raceway angle, so it is not interchangeable with another series. To identify the part, the number stamped on the cup is the governing data.

These cups are used in applications with combined loads: gearboxes, transmission cases, axles of road construction machines, earthmoving equipment, conveyors and agricultural machinery. In Argentina they appear in industrial plant maintenance, heavy machinery repair shops and mining equipment. Also in machine tool spindles and press rolls, where rigidity and clearance adjustment are critical to the service life of the assembly.

To select the correct cup, take into account the cone it will work with: the cup and the cone are chosen as a set, not separately. Check the cup outside diameter and width, and the raceway angle. During assembly, the cup is press-fitted into the housing with suitable tools, without striking the raceway. Lubrication and sealing of the assembly define service life: use compatible grease or oil and renew the seals if there is contamination.

Regarding equivalences, tapered roller bearings are identified by the manufacturer's part number and by standardized dimensions. Between brands there may be dimensional interchangeability if outside diameter, width and raceway angle match, but the suffix does not always match. To replace a TIMKEN cup with another brand, compare the actual dimensions and consult a specialist. MR Accesorios Industriales indicates the compatible alternative.
