Inner ring

What is an inner ring?

An inner ring is a cylindrical component used mainly in rolling bearings to provide a stable running surface for rolling elements, such as balls or rollers. It acts as a link between the shaft and the rolling elements, ensuring smooth, efficient rotation. Inner rings are crucial to maintaining the precision and performance of bearings in a variety of mechanical applications.

Different inner ring profiles

Inner rings are available in several profiles to meet specific needs:

• Standard inner rings: Used in conventional bearings, they provide a reliable, uniform running surface for rolling elements.

• Thick inner rings: Designed for applications requiring increased strength and extended service life, they support higher loads and are more resistant to wear.

• Reduced-tolerance inner rings: Offer superior dimensional accuracy for applications requiring extreme precision and minimal backlash.

Special features of inner rings

Inner rings have a number of features that make them essential in a variety of mechanical applications:

• Stable rolling surface: Provide a smooth, uniform surface for rolling elements, enabling smooth rotation and reducing wear.

• Durability: Made from high-quality materials such as hardened steel, they resist wear, impact and corrosive environments.

• Dimensional accuracy: Strict dimensional tolerances ensure a precise fit and optimum bearing performance.

• Ease of assembly: Designed to fit easily on shafts and housings, facilitating installation and replacement.

How to choose the right part number?

To select the right inner ring for your needs, several criteria must be taken into account:

1. Specific application: Identify the specific requirements of your application, such as load type, rotation speed, and environmental conditions (humidity, temperature, chemical exposure).

2. Bushing type: Choose the type of bushing (standard, thick, or close tolerance) according to the loads and performance required. Thick and reduced-tolerance bushings are preferred for demanding applications requiring increased strength and high precision.

3. Dimensions: Make sure that the dimensions (inner diameter, outer diameter, width) perfectly match your application to ensure correct installation and optimum performance.

4. Materials: Select bushings made from materials suitable for the environment in which they will be used. Corrosion-resistant materials, such as stainless steel, are recommended for humid environments or those exposed to chemicals.

Benefits of inner bushings for various industries

• Manufacturing: Used in machine tools and production equipment to ensure smooth rotation and long bearing life.

• Automotive: Essential in engines and transmissions to provide a stable running surface and reduce component wear.

• Aerospace: Used in flight control systems and aircraft engines for their precision and ability to withstand extreme conditions.

• energy: Integrated into turbines and generators to ensure reliable and efficient rotation of critical components.
