JLM813049/JLM813010 RICH 70x110x26

JLM813049/JLM813010 RICH Single Row Tapered Roller Bearing – 70 x 110 x 26 mm – Maximum Load Stability for Demanding Applications

Built for precision. Trusted for endurance. The JLM813049/JLM813010 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—70 mm inner diameter, 110 mm outer diameter, and 26 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 25 mm in width, while the outer ring (cup) is 20.5 mm—ensuring uniform load distribution across rolling elements and enhancing resistance to both radial and thrust forces. With a rounding radius of R1 = 2 mm, it’s designed for smooth operation and reduced stress concentration. At a lean 0.886 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.
