529X/522 RICH 50,8x101,6x34,925

529X/522 RICH Single Row Tapered Roller Bearing – 50.8 x 101.6 x 34.925 mm – Maximum Load Stability for Demanding Applications

Built for precision. Trusted for endurance. The 529X/522 RICH tapered roller bearing is a robust engineering solution for critical high-load applications where rotational accuracy and structural integrity are non-negotiable. With a precise dimensional profile—50.8 mm inner diameter, 101.6 mm outer diameter, and 34.925 mm overall width—this single row tapered roller bearing delivers optimal performance in power transmissions, axle assemblies, agricultural drivetrains, and industrial gearboxes.

Its inner ring (cone) measures 36.068 mm in width, while the outer ring (cup) is 26.988 mm—ensuring uniform load distribution across rolling elements and enhancing resistance to both radial and thrust forces. With rounding radii of R1 = 3.5 mm and R2 = 3.3 mm, it’s designed for smooth operation and reduced stress concentration. At a lean 1.25 kg, it balances mechanical strength with installation efficiency in compact or high-performance assemblies.

Manufactured in China by RICH, this bearing features a modular separable design (cone and cup mount separately), simplifying maintenance in constrained environments. It's an optimal fit for both OEM integration and aftermarket replacement, backed by RICH's commitment to dimensional accuracy, low-friction operation, and fatigue resistance.
