31319 Tapered Roller Bearing 95x200x49.5 mm CONE/CUP

31319 and 30319, are indeed of the exact same boundary size (bore, outer diameter, and total width) according to the ISO standard for metric tapered roller bearings.

While the external dimensions are the same, the difference in the second digit of the code indicates a difference in internal design:

Dimensional Series: The "313" series generally indicates a steeper contact angle compared to the "303" series.

Load Capacity: A steeper contact angle means the 31319 is designed to handle a proportionally higher axial (thrust) load compared to the radial load than the 30319.

Interchangeability: They are dimensionally interchangeable in terms of fitting into a bore and onto a shaft, but they are not dynamically interchangeable-they cannot be mixed and matched in an application, especially where specific load characteristics or bearing settings are required.

95x200x49.5 mm

This is a single-row tapered roller bearing with the model number 31319. This is one of the most basic and widely used type of tapered roller bearings. The bore diameter of this bearing is 95 mm, the outer diameter is 200 mm, and the total width is 49.5 mm.

This tapered roller bearing set consists of two main separable parts: the cone (inner ring) assembly and the cup (outer ring). Tapered roller bearings are able to carry radial and axial load in one direction simultaneously. If installed correctly it has relatively long service life compared to other bearing type.
