What are SKF Spindle Bearings?

SKF spindle bearings are super-precision bearings engineered for high-speed applications that require a high level of running accuracy such as machine tool spindles. These super-precision bearings usually come with specific features for specific operating conditions and each offers superior rigidity and they are optimized for speed.
 

Where SKF Spindle Bearings are Made

As you may expect, SKF spindle bearings are made at top-of-the-art facilities across different countries to guarantee their availability. The main factory is located in the country of origin of the company, Sweden. However, there are other important factories producing SKF precision bearings in the following countries:

  • France
  • Germany
  • USA
  • China

SKF Spindle Bearings Tolerances

To deal with the highest running accuracy and dimensional precision required by high-speed machine tools, SKF spindle bearings are designed and manufactured to tight tolerance classes such as P4A, P4C or SP.

By complying with these tolerance classes, SKF super-precision bearings warrant the running and dimensional accuracy required by machine tool spindles.

Types of SKF Spindle Bearings

Discover the diverse range of SKF spindle bearings designed to meet the unique needs of various applications:

Angular Contact Ball Bearings

Angular contact ball bearings are designed to accommodate combined radial and axial loads. They have raceways in the inner and outer rings that are inclined relative to the bearing axis, allowing them to support both radial and axial forces. The contact angle between the balls and the raceways is designed to optimize load distribution and reduce friction. Angular contact ball bearings are available in different variants to suit different application requirements. They are commonly used in applications such as machine tool spindles, pumps, and gearboxes, where high precision and reliability are essential. 

Cylindrical Roller Bearings

Cylindrical roller bearings are designed to support high radial loads and moderate axial loads. They have cylindrical rollers that are arranged parallel to the axis of the bearing and held in place by cages or full complement designs. This configuration allows cylindrical roller bearings to provide high radial load capacity and rigidity. They are available in various types, including single row, double row, and multi-row configurations, as well as with different cage designs and materials. Cylindrical roller bearings are commonly used in applications such as electric motors, gearboxes, and industrial machinery, where high radial load capacity and rigidity are required.

Double-Direction Angular Contact Thrust Ball Bearings

Double-direction angular contact thrust ball bearings are designed to accommodate axial loads in both directions. They consist of two single-row angular contact ball bearings mounted back-to-back. This configuration allows for high axial load carrying capacity and rigidity. These bearings are commonly used in applications where high precision and reliability are required, such as machine tool spindles and gearboxes.

Axial-Radial Cylindrical Roller Bearings

Axial-radial cylindrical roller bearings, also known as cylindrical roller bearings with axial guidance, are designed to support combined radial and axial loads. They feature cylindrical rollers arranged radially and axially between raceways. This unique design allows for high radial load capacity and moderate axial load capacity. These bearings are commonly used in rotary tables, indexing tables, and other precision machinery where high rigidity and accuracy are critical.

Angular Contact Thrust Ball Bearings for Screw Drives

Angular contact thrust ball bearings for screw drives are specifically designed to support axial loads in screw drive applications. They feature a contact angle that allows them to accommodate both radial and axial loads simultaneously. These bearings are often used in screw drives found in machine tools, precision equipment, and automotive applications. They offer high precision, reliability, and efficiency in high-speed and high-load operations.

Each of these types of SKF spindle bearings offers unique features and benefits, making them suitable for various applications in industries such as aerospace, automotive, and manufacturing.

Jure Pleško is co-owner of Tuli, a family business that helps innovative mechanical engineers by supplying them with machine elements to assemble machines and devices. As part of a family tradition, he grew up with machine elements from an early age and also completed his studies in mechanical engineering, earning a Master's degree in Mechanical Engineering. As a 2-year-old child he was also the inspiration for the company name, because at that time he was shouting a lot and hence the name Tuli, which in translation means screaming. Jure is an innovative mechanical engineer himself, which he proved during his student years with the construction of an electric vehicle, which was also awarded by the Slovenian Fund for Human Resources Development and Scholarships.
