Tapered roller bearings are divided into: single row tapered roller bearings and matched pairs of single row tapered roller bearings. It is divided into metric and inch.
Example marking - metric bearings: 30204 A, 30205A, 30206 A, 30207 A, 30208 A, 30209 A, 30210 A, 32204 A, 32205 A, 32206 A, 32207 A,
32208 A, 32209 A, 32210 A, 32211 A, 33211/Q, 33207/Q, 30308 J2/Q, 30221 A ........

Tapered roller bearings inch dimensions
Tapered roller bearings not only meet but even exceed the requirements for quality and performance in applications in which they are exposed
to high combined loads and tilting moments.
The design combines the logarithmic profile rollers and orbits with optimized surface roughness (topography) and the contact area between
the roller ends and the guide flange.
These features contribute to significant reduction in noise and vibration and also reduce edge surges.
Tapered roller bearings marked with suffix "Q" demonstrably improve productivity and increase uptime while reducing maintenance and
operating costs.
