Bearings Steel Ball

In the industrial sector, the performance of equipment relies on the quality of each mechanical component. Among them, the ball bearing is at the heart of a structure requiring precision and efficiency.

At Rubix, our stocked parts are reliable and available for demanding professionals. Depending on your technical needs, you benefit from a rigorous selection with an excellent quality-price ratio. Ready for immediate dispatch, they ensure optimal equipment operation and the continuity of your production.

A ball is a spherical mechanical element inserted into a bearing. It allows the transformation of sliding friction into rolling friction between two moving surfaces. It is an essential component for reducing wear and improving the smoothness of rotary movements. The ball bearing thus extends the lifespan of your machines.

The chrome steel balls offered by Rubix are designed for various industrial environments. They are particularly used by manufacturers of industrial machinery, automotive builders, and manufacturers of common mechanical equipment.

They offer numerous advantages:

• excellent wear resistance;
• high hardness;
• an excellent compromise between price and performance;
• perfect compatibility with environments without excessive humidity or extreme heat.

These balls are often integrated into a mechanical assembly that demands precision and reliability. They ensure the stability of your industrial processes by allowing smooth operation within a closed mechanical circuit.

The stainless steel balls meet the requirements of the most demanding environments. They are commonly used in the food, medical, and maritime sectors. For customised use or critical applications, these balls provide a true safety net. They perform effectively in all seasons, including on outdoor equipment exposed to the elements.

They are distinguished by:

• superb corrosion resistance;
• a surface compliant with hygiene standards;
• compatibility with humid, chemical, or sensitive environments.

Rubix offers different types of balls tailored to the industry's requirements. They provide proven technical solutions for professionals seeking reliability, performance, and competitive pricing. Each ball meets a specific need, depending on the activity, working environment, and load constraints.

To ensure the quality and interchangeability of ball bearings, Rubix only offers references that comply with international standards:

• ISO 3290,
• DIN 5401,
• AFBMA (ABMA) 10.

These standards define criteria concerning diameter tolerances, sphericity, surface roughness, and roundness.

The balls are thus classified by grades: G10, G25, G100, G500, etc. The lower the grade, the more precise the ball. For example, a G10 ball has very low variation in its diameter and sphericity errors. It is intended for a mechanical assembly with high precision requirements.

Our brands are recognised for their quality and reliability to meet the demands of the industrial sector.

• PTN: An exclusive brand of Rubix, PTN offers a complete range of balls suitable for common industrial applications. PTN products display a high level of performance, an attractive purchase price, and rapid availability.
• SKF: A global leader in bearing manufacturing, SKF offers a wide range of reliable and high-performance balls. They ensure smooth and precise rotation for demanding industrial applications.

The choice of a ball bearing must take into account the actual conditions of use and the industrial environment. Opting for an unsuitable ball may result in your equipment failing to operate correctly. Here are some useful recommendations to guide your selection:

• In the medical, food, and maritime sectors, stainless steel balls are essential. Their corrosion resistance and compatibility with hygienic environments make them an indispensable choice.
• In the woodworking industry, dusty environments require balls capable of resisting contamination for smooth rotation.
• In the mechanical sector, chrome steel balls offer an excellent compromise between robustness and performance. With a lower price, they are ideal for equipment subjected to regular loads in a dry environment.
• For the chemical or electronic sector, there are non-conductive glass or plastic balls. They prevent any electromagnetic interference and resist aggressive substances.

The sharp eye of the Rubix teams guides you towards balls suited to your activity. Our catalogue meets the specific needs of major players in the industry. We thus offer a complete range of balls, tab washers, adapter sleeves, grooved and lock nuts, and bearing accessories.
