6222-ZZ Double Shielded Deep Groove Ball Bearing For Power Generation | 110×200×38 mm

6222-ZZ Double Shielded Deep Groove Ball Bearing For Power Generation | 110×200×38 mm

Engineered for optimal balance between load capacity and high-speed efficiency, the 6222-ZZ is a premium single row deep groove ball bearing featuring a double-shielded architecture. Unlike open bearings that require continuous external lubrication, the "ZZ" configuration utilizes twin pressed-steel shields to lock in factory-filled grease while blocking the ingress of dust, debris, and moderate environmental contaminants. This maintenance-free design makes it an indispensable component for electric motors, industrial blowers, and automated systems where reliable, long-term operation without relubrication is essential.

6222-ZZ Deep Groove Ball Bearing 110x200x38 mm | Maintenance-Free | Metal Shielded

Manufactured to stringent ISO tolerances, the 6200 series provides a highly versatile, medium-duty dimensional profile. The 6222-ZZ specifically excels in applications requiring low friction torque and acoustic dampening at high operational speeds. By utilizing non-contact steel shields, this bearing achieves exceptional rotational velocities without generating the parasitic drag associated with rubber contact seals. The result is a highly efficient, thermally stable bearing ready to deliver immediate performance in demanding electromechanical machinery.

Key Performance Features

01. Dual-Shielded Protection (ZZ)

Equipped with two non-contact pressed steel shields, the 6222-ZZ provides a formidable barrier against particulate contamination. This shielding retains the premium internal grease formula for the entire lifespan of the bearing, entirely eliminating the maintenance downtime associated with manual regreasing.

02. Precision GCr15 Chrome Steel Construction

Manufactured from high-purity, vacuum-degassed GCr15 bearing steel. Both the inner/outer rings and the precision-grade steel balls are subjected to advanced heat treatment, yielding outstanding surface hardness and wear resistance. This metallurgical superiority ensures reliable performance against radial loads and moderate axial thrust.

03. Optimized High-Speed Kinematics

Because the metal shields do not make physical contact with the inner ring, there is absolutely zero seal-induced friction. This translates to lower operational temperatures, reduced energy consumption, and the ability to sustain higher RPMs compared to equivalently sized sealed (RS) bearings.

Design & Configuration

The 6222-ZZ is a "greased-for-life" component. It arrives pre-lubricated from the Welink Bearing factory with a precise fill of high-performance lithium-based grease, ready for immediate installation. Do not wash or heat this bearing prior to mounting, as this will compromise the internal lubrication. If your application involves heavy water washdowns, corrosive chemicals, or extreme fine powder, please contact our engineering team to explore our rubber-sealed (6222-2RS) alternatives for maximum environmental protection.

"Combining low-friction velocity with zero-maintenance reliability, the 6222-ZZ shielded bearing is engineered to keep your critical machinery running smoother, for longer."
