4-Point Contact Bearings
Made in Germany
Product description
Neuweg Four-Point Contact Ball Bearings are designed to accommodate high axial loads in both directions while supporting moderate radial loads within a compact bearing arrangement. Their unique contact geometry enables efficient load distribution, making them an ideal solution for applications where space is limited and performance requirements are high.
By providing the functionality of a paired bearing arrangement within a single bearing, Four-Point Contact Ball Bearings help simplify equipment design, reduce installation space and optimise overall system efficiency.
Engineered for high-speed operation and demanding operating conditions, these bearings are widely used in pumps, compressors, gearboxes and other industrial machinery where reliable axial load support is critical.
Manufactured to the highest quality standards, Neuweg Four-Point Contact Ball Bearings deliver dependable performance, long service life and reduced maintenance requirements.

Four-point contact bearings support axial loads in both directions within a single bearing, whereas standard angular contact bearings typically require paired arrangements.
Yes. They support radial loads in addition to axial loads, although they are primarily selected for axial-dominant applications.
The split inner ring allows more rolling elements to be incorporated, increasing load-carrying capacity and improving stiffness.
Yes. Extended inner ring variants are available to support specific mounting and alignment requirements.
Selection depends on axial load, radial load, speed, and available installation space. Neuweg can provide guidance based on application parameters.
