Łożyska kulkowe zwykłe SKF 6211/VA201

Łożyska kulkowe zwykłe są szczególnie wszechstronne. Nadają się do wysokich i bardzo wysokich prędkości, przenoszą obciążenia promieniowe i osiowe w obu kierunkach i wymagają niewielkiej konserwacji. Ponieważ łożyska kulkowe zwykłe są najczęściej stosowanym typem łożysk, SKF oferuje je w wielu wersjach, wariantach i rozmiarach.

This SKF single-row ball bearing is specifically designed for high-temperature applications (up to +250 °C), ensuring reliability and performance under demanding conditions.

Features:
This bearing, capable of withstanding extreme temperatures, is equipped with a deep-drawn steel cage treated with manganese phosphating to promote lubricant adhesion and running-in performance. Lubricated with a mixture of polyalkylene glycol and graphite, it operates smoothly and reliably at temperatures ranging from -40 to +250 °C. Its C5 multiple radial clearance prevents seizure and compensates for dimensional variations caused by rapid temperature changes, particularly during sudden cooling. Its open design also promotes heat dissipation.

Maintenance:
With no seals or metal flanges, this bearing is not protected from external contaminants, and slight lubricant leakage may occur. It is therefore recommended to check the condition of the grease every six months. If no dry lubricant film is present on the raceways, it is advisable to clean off any residue with a solvent before refilling the bearing with the appropriate grease. Regular inspections are also recommended to detect any abnormal noises, which may indicate misalignment.

Sealing:
This bearing is designed without a protective seal, making it vulnerable to contaminants such as dust, particles, and liquids. However, this open design allows for simplified maintenance and improved heat dissipation. It is therefore suitable for low-contamination environments or systems requiring optimal cooling.

Brand Information:
SKF (Svenska Kullager-Fabriken) is a Swedish multinational group founded in 1907 and a world leader in the field of mechanical bearings. SKF is one of the world’s leading suppliers of bearings, seals, mechatronic components, lubrication systems, and services designed to improve the reliability of rotating equipment and ensure its performance. SKF products can be used anywhere there is motion. They are used in some 40 industrial sectors, such as automotive transportation, aerospace, rail, manufacturing, food and beverage, medical, traditional and renewable energy, and agriculture.

Key Features:
- Extended temperature range from -40 to +250 °C;
- Multiple C5 internal clearance to effectively manage temperature variations;
- Optimal heat dissipation thanks to the open design;
- Robust design, ideal for harsh environments.

Applications:
This bearing is particularly well-suited for high-temperature industrial applications in clean, controlled environments. It is especially suitable for automatic ovens in the food processing industry, industrial ovens, and production lines.
