Deep groove ball bearing SKF 6306-2ZNR, Outer diameter: 72 mm | Width: 19 mm | Inner diameter: 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 deep groove ball bearing, suitable for a variety of industrial applications, combines durability with enhanced protection in moderately contaminated environments. Its integrated stop ring in the outer ring groove ensures optimal axial retention. Ideal for medium to high rotational speeds, it ensures smooth operation with low resistance torque.

Features:
This single-row ball bearing features standard radial clearance, ensuring reliable performance at high rotational speeds. Its integrated stop ring in the outer ring provides strong axial retention and reduces the risk of misalignment. It can handle heavy radial loads and moderate axial loads. Its sheet steel cage provides good resistance to constant loads while withstanding shocks and momentary loads. Additionally, this bearing is designed to offer advanced protection against contaminants thanks to its two metal shields.

Maintenance:
Lubricated for life with high-quality grease, this bearing does not require relubrication, which simplifies maintenance and reduces costs and downtime. Its metal shields on both sides also provide reliable protection against medium- and large-sized contaminants. However, it is recommended to periodically check the bearing’s condition by monitoring noise, temperature, and any signs of premature wear.

Sealing:
Thanks to its two metal shields, this bearing is protected against contaminants such as medium- and large-sized particles. These steel-sheet shields create an effective mechanical barrier, limiting the intrusion of debris and preventing lubricant loss. This sealing system minimizes friction losses while reducing the risk of contamination, thereby extending the bearing’s service life.
