Axial Ball Bearings: Precision & Performance from CMM Italy

CMM Italy, based in Mellaredo di Pianiga (VE) at Via Tagliamento, 10, is a leading manufacturer of high-quality industrial components, offering a comprehensive range of bearings designed for superior performance and reliability. Among our specialized products, axial ball bearings (also commonly known as thrust ball bearings) stand out for their critical role in applications requiring the accommodation of purely axial loads.

What are Axial Ball Bearings?
Axial ball bearings are a type of rolling-element bearing specifically designed to support axial loads, meaning forces acting parallel to the axis of rotation. Unlike radial bearings, they are not intended to carry significant radial loads. Their unique design typically consists of two or more rings (washers) with raceways, and a set of balls contained within a cage.

Axial ball bearings CMM Italy Key Characteristics:

• Load Direction: Primarily handle axial loads in one or both directions.
• Design: Available in single-direction and double-direction configurations.
• Components: Typically comprise a shaft washer, a housing washer(s), and a ball and cage assembly.
• Mounting: Often separable, meaning the washers and ball assembly can be mounted independently, simplifying installation.
• Speed: Generally suitable for moderate to high speeds, depending on the specific design and lubrication.

Technical Details & Types
CMM Italy offers a variety of axial ball bearing types to meet diverse industrial needs:

• Single-Direction Axial Ball Bearings: Composed of two washers and a single ball and cage assembly. Ideal for applications where axial load is applied in only one direction.
- ◦ Example Application: Swivel hooks, vertical pump shafts.
• Double-Direction Axial Ball Bearings: Feature a central shaft washer, two housing washers, and two ball and cage assemblies. Designed to accommodate axial loads in both directions.
- ◦ Example Application: Machine tool spindles, automotive steering gears.
• Angular Contact Axial Ball Bearings: A specialized type designed to accommodate both axial and radial loads, though primarily for axial forces.
- ◦ Example Application: Precision machine spindles, rotary tables.
• Miniature Axial Ball Bearings: Smaller versions used in compact designs where space is limited, often found in precision instruments.

Materials & Precision:
CMM Italy's axial ball bearings are manufactured using high-grade bearing steel (e.g., AISI 52100 / 100Cr6) for optimal hardness, wear resistance, and fatigue life. We adhere to strict precision standards to ensure smooth operation, minimal friction, and extended service life.

Applications

• Machine Tools: Spindles, rotary tables, and feed screws.
• Automotive Industry: Steering gears, clutches, and certain transmission components.
• Pumps & Compressors: Vertical pumps, mixing equipment.
• Lifting & Hoisting Equipment: Cranes, hoists, and swivel hooks.
• Agricultural Machinery: Various rotating components subjected to axial thrust.
