Deep groove ball bearing SNR 6207C3, Outer diameter: 72 mm | Width: 17 mm | Inner diameter: 35 mm

This single-row, open deep groove ball bearing from the SNR brand is specially designed for quiet and stable operation in clean or moderately stressed environments. The open design without seals allows efficient heat dissipation and a low friction torque. It is ideal for industrial applications that require high speeds and precision while reducing maintenance effort.

Features:
This deep groove ball bearing consists of a single row of rolling elements, a robust stamped steel cage and an open construction. The bearing features an increased radial internal clearance (C3), which compensates for thermal expansions and ensures low-friction rotation at high speeds. The steel cage guides the balls precisely and provides high mechanical load capacity in dynamic applications. The SNR bearing combines compactness, reliability and performance in one.

Maintenance:
This bearing requires careful and regular maintenance, especially in unprotected environments. Due to the absence of seals it is sensitive to dust, moisture and contaminants. A clean, controlled installation location is therefore crucial. Regular lubrication is essential to maintain performance. The selection of the appropriate lubricant and the type of lubricant supply (manual, automatic or centralized) must be matched to speed, load and environment. Consistent maintenance ensures the longevity and functional safety of the bearing.

Seal:
This deep groove ball bearing has no integrated seal. It is therefore intended for clean, protected environments where exposure to dust, moisture or liquids is limited. The open design allows direct visual inspection as well as excellent heat dissipation, but requires more frequent inspections to ensure the cleanliness of the bearing housing and the condition of the lubricant.
