Kuličkové ložisko s hlubokou drážkou SKF 6306-2Z/C4, Vnější průměr: 72 mm | Šířka: 19 mm | Vnitřní průměr: 30 mm

Ball bearings are essential mechanical components that reduce friction and support various loads in a wide range of industrial applications. Among them, deep groove ball bearings stand out for their versatility, ability to operate at high speeds, and low maintenance requirements.

This SKF-brand deep groove ball bearing effectively supports radial and axial loads. Easy to install, it features a sheet steel cage and two metal shields. It has an enlarged internal radial clearance (C4), making it an ideal choice for very high-speed applications.

Features:
This deep-groove ball bearing is designed with a single-row ball structure and a sheet steel cage, enabling it to effectively withstand heavy radial loads while supporting moderate axial loads. The flanges on either side of the bearing provide protection against contaminants, such as dust and medium-sized particles. The enlarged internal radial clearance (C4) allows the bearing to operate at very high speeds, minimizing heat and friction for smooth rotation. The bearing’s very low resistance torque and its ability to maintain internal lubrication ensure reliable performance under demanding conditions.

Maintenance:
This bearing requires very little maintenance. Protected by two flanges and pre-lubricated for life with high-quality grease, it does not require relubrication. The bearing is also protected from medium-sized contaminants. These features reduce maintenance costs and downtime. To ensure optimal service life, however, it is recommended to perform periodic inspections, particularly monitoring noise levels, temperature, and the integrity of external components.

Sealing:
This deep-groove ball bearing is equipped with two metal shields that provide effective sealing against medium-sized contaminants, such as dust or debris. These steel-sheet shields form a mechanical barrier that prevents debris from entering and effectively protects the bearing from solid contaminants. They also ensure optimal lubricant retention inside the bearing.
