The SKF S71919ACDGA/P4AVP304 is a high-performance super-precision bearing designed for demanding applications that require excellent speed, accuracy, and reliability. Below is a detailed overview of its key specifications, structure, features, and applications.

Dimensions:

This super-precision bearing has a bore diameter of 95 mm, an outside diameter of 130 mm, and a width of 18 mm. Its size allows it to fit into compact machinery while providing exceptional performance, especially in high-speed rotating components.

Structure:

The SKF S71919ACDGA/P4AVP304 bearing is an angular contact ball bearing, featuring a contact angle that allows it to sustain both radial and axial loads. The angular contact design enables better load distribution, particularly under high axial stress. This bearing is built with ceramic balls (hybrid construction) instead of traditional steel balls, which significantly reduces friction, increases speed, and enhances resistance to wear. The outer and inner rings are made of high-grade, high-temperature resistant steel for durability and longevity.经久耐用。

Additionally, this bearing belongs to the P4A class, which indicates its high precision grade, as per ISO standards. It ensures extremely tight tolerances for optimal positioning accuracy and smooth rotation. The GA suffix indicates that it comes preloaded to reduce the likelihood of skidding, ensuring optimal rigidity during high-speed operations.

Features:

1. High-Speed Capability: With hybrid construction, the ceramic balls reduce friction and enable the bearing to perform at very high speeds, making it ideal for high-speed spindles in machine tools and precision instruments.

2. Exceptional Precision: As a super-precision bearing, it meets the requirements for high-performance applications where accuracy is critical. The P4A tolerance class ensures smooth, precise operation with minimal vibration and noise.

3. Preloaded for Rigidity: The preloaded structure (GA) ensures stiffness, especially when axial forces are high, thus maintaining the bearing’s alignment and reducing potential misalignments during operation.

4. Low Friction: The ceramic balls minimize rolling resistance, providing smooth movement while reducing heat generation, allowing for prolonged high-speed operation without thermal stress.

5. Durability and Long Life: The combination of high-quality steel rings and ceramic balls makes this bearing resistant to wear and corrosion, even under harsh operating conditions, thus extending its service life.

Applications:

The SKF S71919ACDGA/P4AVP304 is primarily used in applications requiring extreme precision, high rotational speeds, and low vibration. Typical industries and machinery include。

• Machine Tool Spindles: Ideal for high-speed CNC machines and other precision machinery where accuracy and speed are critical.
