6710-ZZ Thin-Section Deep Groove Ball Bearing | Precision Space-Saving Solution | 50×62×6 mm

6710-ZZ Thin-Section Deep Groove Ball Bearing | Precision Space-Saving Solution | 50×62×6 mm

Engineered specifically for restricted-space environments, the 6710-ZZ is an ultra-thin section deep groove ball bearing that delivers uncompromising precision without unnecessary bulk. Equipped with dual non-contact metal shields (ZZ), this bearing effectively blocks particulate contamination while permanently retaining its high-quality factory lubrication. Featuring a large 50mm bore, a 62mm outer diameter, and a remarkably slim 6mm width, it is the ultimate solution for robotics, optical equipment, and industrial automation assemblies where weight reduction and tight radial clearances are critical.

6710-ZZ Deep Groove Ball Bearing 50x62x6 mm | Metric Series | Double Shielded

A highly efficient, precision-crafted bearing utilizing an extra-thin wall geometry. Developed to provide reliable rotational support in heavily constrained designs, the 6710-ZZ accommodates light to moderate radial loads as well as axial loads in both directions. By bridging the gap between a large shaft diameter and an extremely compact housing, this component ensures low rotational friction, high structural stiffness, and an extended operational lifespan for complex machinery.

Key Performance Features

01. Ultra-Thin Profile for Compact Engineering

The defining characteristic of the 6710-ZZ is its exceptionally slim cross-section relative to its bore size. With a width of just 6mm, it empowers design engineers to shrink housing dimensions and reduce overall system weight. It is the perfect alternative to standard-sized bearings in applications where saving space and shedding grams are primary engineering goals.

02. Optimized Weight-to-Performance Ratio

Despite its lightweight construction, the 6710-ZZ maintains strict geometric tolerances to deliver smooth, low-torque operation. Its design significantly lowers the rotational inertia of the assembly, which improves response times in servo-driven applications and reduces power consumption in automated systems.

03. Reliable Protection & Low Maintenance

Fitted with two pressed steel shields (ZZ), this bearing is shielded against dust, metal shavings, and other environmental debris. Because it is pre-lubricated for life with high-performance grease, it operates as a low-maintenance solution, preventing premature wear and minimizing downtime in hard-to-access mechanical assemblies.
