Łożyska kulkowe zwykłe SKF 6202-2RSH/C4

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-brand deep groove ball bearing is designed to offer an optimal combination of performance and durability. Versatile and reliable, this bearing supports radial and axial loads in both directions, while being easy to install. Its reinforced seal makes it ideal for dusty or humid environments, ensuring extended service life.

Features:
This deep-groove ball bearing is equipped with a sheet steel cage, which provides excellent resistance to shocks and constant loads. Its acrylonitrile-butadiene rubber (NBR) seals ensure optimal sealing to prevent both lubricant leakage and the entry of solid or liquid contaminants into the bearing. Thanks to its increased internal radial clearance (C4), this bearing is designed to minimize friction and promote better heat dissipation. This design enables reliable operation under demanding conditions.

Maintenance:
This deep-groove ball bearing requires very little maintenance thanks to its sealed seals, which keep the lubricant inside and prevent the entry of both solid and liquid contaminants. However, it is recommended to regularly monitor operating temperature and vibrations to ensure optimal performance and prevent premature wear.

Sealing:
This bearing is equipped with nitrile-butadiene rubber (NBR) lip seals with steel sheet reinforcement on both sides of the bearing, providing effective protection against external contaminants, such as dust and water. NBR is particularly resistant to oils and greases, which helps keep the lubricant inside the bearing and extends its service life. The RSH seal features a lip in axial contact with the inner ring, inserted into a radial groove, and incorporates a secondary sealing lip capable of withstanding high-pressure cleaning, thereby preventing water from entering. The design of this lip ensures optimal stability, preventing it from being pushed into the bearing.

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:
- Excellent sealing provided by nitrile-butadiene rubber (NBR) seals, which prevent contamination by dust and water;
- Increased internal radial clearance (C4) for reduced friction;
- Minimal maintenance thanks to the sealed design, which keeps the lubricant inside the bearing;
- Steel sheet cage offering good load-bearing capacity and high durability under demanding operating conditions;
- Suitable for dusty and humid environments, thereby extending the bearing’s service life.

Applications:
This deep-groove ball bearing is particularly well-suited for electric motors, industrial pumps, as well as fans and material-handling systems operating in dusty or humid environments. It is also suitable for the food processing and marine industries, where protection against contamination is crucial. This bearing can be used in household appliances, such as refrigerators or vacuum cleaners, as well as in agricultural machinery and gearboxes, offering durability and reliability even under harsh conditions.
