Product Description

The DB-59722 (DB59722) is a high-precision Cylindrical Roller Bearing engineered without an inner ring, featuring compact dimensions of 35.6mm x 57.2mm x 17.9mm (Inner Diameter x Outer Diameter x Width). Manufactured from premium GCr15 chrome steel with a durable steel cage, this design allows the bearing to mount directly onto a hardened and ground shaft, effectively using the shaft itself as the inner raceway. This configuration significantly increases shaft rigidity and load-carrying capacity while reducing the overall assembly footprint—an ideal solution for space-constrained automotive drivetrain applications.

Specifically designed for automotive gearboxes and transmission systems, the DB-59722 offers excellent radial load support, high rotational accuracy, and exceptional wear resistance. Available in P0, P6, and P5 precision grades, it ensures low vibration, smooth operation, and extended service life under demanding high-speed and heavy-load conditions.

Technical Specifications

Key Features & Advantages

• No Inner Ring Design – Eliminates the need for a separate inner ring; the bearing runs directly on a hardened shaft, reducing assembly size, weight, and component count while improving shaft concentricity.

• High Radial Load Capacity – Cylindrical rollers provide line contact with raceways, delivering exceptional radial load performance ideal for automotive gearbox shafts.

• Premium Material & Durability – Made from high-grade GCr15 chrome steel for outstanding hardness, fatigue strength, and long-term reliability under fluctuating temperatures and heavy loads.

• Precision Options – Available in P0 (standard), P6, or P5 precision classes to match your speed, noise, and alignment requirements.

• Smooth & Stable Rotation – The precision steel cage ensures proper roller spacing, minimizing friction, heat generation, and wear even at high rotational speeds.

Applications

• Automotive gearboxes and manual/automatic transmissions

• Heavy-duty vehicle drivetrain systems

• Industrial gear reducers and power transmission units

• General machinery where a compact, high-load bearing is required with a direct shaft-mount design
