Both the 133 and 134 series bearings consist of an inner ring with integral internal teeth, an outer ring, and three rows of cylindrical rollers arranged in separate raceways. The three rows are dedicated to handling specific load directions: one row supports axial loads in one direction, a second row supports axial loads in the opposite direction, and the third row supports radial loads. This independent load path design ensures optimal load distribution and allows each roller row to be sized precisely for its specific function.

The internal gear is machined directly on the inner ring, allowing the driving pinion to be positioned inside the bearing envelope. This internal gear arrangement offers several advantages: the gear teeth are protected from external contamination and mechanical damage, the overall footprint of the rotating assembly is reduced, and the machine design can be more compact. Both rings are provided with mounting holes for straightforward bolted installation.
