Seal design also varies, with common designs being single-acting, double-acting, and U-cup seals
hydraulic ram oil seals. The choice depends on the specific application requirements, such as pressure, speed, and duty cycle. Additionally, some advanced designs incorporate anti-extrusion rings to prevent seal deformation under high pressure.

The American Bearing Manufacturers Association (ABMA) and International Organization for Standardization (ISO) have established standardized systems for sizing tapered roller bearings. The ABMA system uses a numerical series (e.g., 20, 22, 24, etc, 20, 22, 24, etc
, 20, 22, 24, etc, 20, 22, 24, etc
taper roller bearing size.) to indicate the bearing's nominal outer diameter, while the ISO system combines the bore diameter and series into a single number (e.g., 0719).


On the other hand, spherical roller bearings have an inner ring, an outer ring, and a cage with barrel-shaped rollers. These bearings are designed to accommodate both radial and axial loads, making them highly versatile. Spherical roller bearings are particularly useful in applications where the shaft has a significant misalignment or where there is a need for high thrust loads. The barrel-shaped rollers in spherical roller bearings allow them to accommodate misalignment and still maintain proper contact between the bearing surfaces, ensuring smooth operation The barrel-shaped rollers in spherical roller bearings allow them to accommodate misalignment and still maintain proper contact between the bearing surfaces, ensuring smooth operation
