ALS 40 ABM Bearing Product Overview & Core Advantages
The ALS 40 ABM is a high-precision **single row angular contact ball bearing** engineered for demanding applications requiring exceptional accuracy and reliability. Its **30° contact angle** is optimized to support significant **combined loads**—handling both radial forces and substantial unidirectional axial loads simultaneously. Manufactured to **P6 (ABEC-3) tolerance class**, it delivers superior running accuracy and rotational stability. The bearing comes **pre-lubricated** for immediate operation and features an **open design** for application-specific lubrication management, making it an ideal component for high-performance systems where **high rigidity** and precision are paramount.
ALS 40 ABM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| ALS 40 | Standard bearing series designation. |
| ABM | Indicates specific internal design and performance features, including the **30° contact angle**. |
| Open (Seal Type) | No integral seals or shields, allowing for custom lubrication systems and higher potential speeds. |
ALS 40 ABM Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The **single row design** with a **30° contact angle** provides excellent **high rigidity** and is capable of supporting high **radial dynamic load ratings** of 41,850 lbf and **radial static load ratings** of 42,750 lbf. The optimized **shoulder diameters** on both rings ensure secure positioning and maximum load support.
- Precision & High-Speed Performance: Manufactured to a **P6 tolerance class**, the bearing guarantees precise running and minimal vibration. The **brass cage** ensures stability and durability, contributing to reliable operation at the specified **limiting speed** of 3,600 rpm.
- Material & Construction: Constructed from **chrome steel** for both rings and balls, the bearing offers high hardness, wear resistance, and long service life. The **open construction** facilitates efficient heat dissipation and allows for advanced lubrication solutions tailored to specific operational needs.
- Ready-to-Install: The bearing is supplied **pre-lubricated**, enabling immediate installation and startup, which reduces assembly time and complexity.
ALS 40 ABM Bearing Typical Application Areas
This **precision angular contact ball bearing** is ideally suited for applications requiring high accuracy and the ability to handle combined loads. Key industries and equipment include:
- Machine Tool Spindles: For high-speed milling, grinding, and turning centers.
- Precision Gearboxes: Especially in industrial robotics and automation systems.
- Pumps and Compressors: Where reliable performance under radial and axial loads is critical.
