ALS 28 ABP Bearing Product Overview & Core Advantages
The ALS 28 ABP is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. This precision bearing is designed to simultaneously accommodate significant radial loads and unidirectional axial loads, thanks to its optimized 30° contact angle. Manufactured to P6 (ABEC-3) tolerance class, it ensures exceptional running accuracy and rotational stability. Its compact design, featuring a 28.575 mm width and 88.9 mm bore diameter, makes it ideal for space-constrained, high-reliability systems demanding high rigidity and precise shaft guidance.
ALS 28 ABP Bearing Model Code Explained, Specifications & Naming Convention
- ALS 28: Denotes the specific bearing series and size designation.
- A: Signifies the 30° contact angle, optimized for high axial load capacity.
- B: Indicates the P6 (ABEC-3) tolerance class for high precision.
- P: Specifies the Nylon cage (polyamide) for reduced weight, lower friction, and superior high-speed performance.
ALS 28 ABP Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The single row design with a 30° contact angle is engineered to handle substantial combined radial and axial loads in one direction efficiently.
High-Speed Performance: The lightweight Nylon cage minimizes centrifugal forces, enabling a high limiting speed of 5,000 rpm while maintaining stability and reducing operating temperature.
Precision & Rigidity: Manufactured to P6 tolerance with precise raceway geometry, this bearing provides high running accuracy and system rigidity, critical for minimizing deflection under load.
Material & Lubrication: Constructed from Chrome Steel for both rings and balls, ensuring high durability and fatigue resistance. The bearing is pre-lubricated for immediate operation within a temperature range of -30°C to 110°C.
