Deep groove ball bearing SNR 6206F600, Outer diameter: 62 mm | Width: 16 mm | Inner diameter: 30 mm

TOPLINE deep groove ball bearing, radial contact, pressed steel cage, open, applications upto 350°C.

This deep groove ball bearing from the SNR brand was developed for smooth, low-noise and reliable rotation under extreme temperature conditions of up to +350 °C. The open design provides excellent heat dissipation and allows direct access for maintenance. Ideally suited for high-temperature applications with high rotational speeds, this bearing meets the requirements of dynamic and precise systems. It stands out for its robustness, versatility and energy-efficient performance.

Features:
The single-row ball bearing with a pressed steel cage belongs to SNR’s Topline series. It was specifically designed for use at very high temperatures and has a special surface treatment of phosphating combined with a layer of molybdenum disulfide (MoS₂). This coating improves both corrosion protection and lubrication under severe thermal stress.

Please note: MoS₂ reacts with water and can form sulfuric acid – therefore this bearing should not be used in humid environments.

The bearing is not sealed, which minimizes frictional losses and increases mechanical efficiency, enabling low energy consumption and rapid start-up. The radial internal clearance is greater than C5, providing increased freedom of movement between the rolling elements. This allows thermal expansions to be reliably compensated without compromising operational safety or rotational freedom. Thanks to the open construction, operation at very high speeds is possible while providing excellent heat dissipation. The bearing is suitable for high radial loads as well as moderate axial loads in both directions.

Maintenance:
Regular maintenance is required to maintain performance. Due to the lack of sealing, the bearing must be used in clean, dry environments. Periodic re-lubrication using a lubricant suitable for both the operating temperature and the rotational speed is necessary. The condition of the bearing should be continuously monitored, especially at high temperatures, to avoid premature wear.

Sealing:
This model is designed open, i.e. without seals. This allows better cooling and easy access for lubrication, but makes the bearing more susceptible to contamination such as dust, liquids or moisture. This design maximizes the thermal and mechanical properties but requires intensified monitoring and consistent maintenance to increase bearing life.

Brand information:
SNR is a brand of the NTN Group and a globally recognized manufacturer of rolling bearings and mechanical solutions. Founded in France, SNR combines European know-how with Japanese innovation. The company operates in many industrial sectors and is distinguished by its product quality, innovative capability and sustainable technical performance.

Strengths:
• Usable at extreme temperatures up to +350 °C
• Phosphated surface with MoS₂ coating for optimized lubrication and high oxidation resistance
• Low starting torque for energy-efficient operation
• Suitable for very high speeds
• Open design for improved cooling and maintenance access
• High radial load capacity as well as moderate axial load in both directions
• Quiet operation with low vibration
• Pressed steel cage for stability and long-lasting performance

Applications:
This bearing is ideal for equipment operating at high temperatures and low speeds. Typical applications include oven conveyor belts, heat treatment equipment, and production lines for glass, ceramics or steel. It is also used in hot conveying systems, such as powered grippers, conveyor chains or intensive drying installations. Its open design and resistance to extreme temperatures make it a reliable solution for stationary equipment exposed to thermal radiation.
