    Why Ruland?

    • Speeds up to 10,000 RPMs with reduced vibrations due to our standard balanced design.
    • Do not introduce misalignment causing high bearing loads because of proprietary assembly processes that maintain bore concentricity.
    • High torque and torsional stiffness with industry-leading misalignment capabilities.
    • Low inertia for use in highly responsive systems due to the use of high-grade lightweight 2024 t351 aluminum.
