S7010 ACB/HCP4ADGA Bearing Product Overview & Core Advantages
The S7010 ACB/HCP4ADGA is a precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. As a universally matchable (SU) bearing supplied in a pre-set pair, it is designed to accommodate combined loads—significant radial and axial loads in both directions—simultaneously. Its construction with ceramic balls and a P4A super-precision tolerance class ensures high-speed capability, superior rigidity, and extended service life, making it ideal for high-reliability, high-rotational accuracy scenarios.
S7010 ACB/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7010 | Basic bearing designation, indicating a 50mm bore, 80mm OD, and 32mm width. |
| ACB | Angular Contact Bearing with a 25° contact angle. |
| HC | Hybrid Ceramic, signifying ceramic balls for reduced weight, lower friction, and higher speed potential. |
| P4A | Super Precision Tolerance Class, exceeding ABEC 7/ISO P4 standards for exceptional running accuracy. |
| DGA | Designates a universally matchable (SU) pair with Extra Light (Class A) preload. |
S7010 ACB/HCP4ADGA Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The use of ceramic balls within a chrome steel ring structure significantly reduces centrifugal forces, enabling a higher limiting speed of 41,000 rpm. This construction also provides superior resistance to wear and thermal deformation.
High Rigidity & Load Capacity: The 25° contact angle and the use of a matched pair arrangement provide excellent high rigidity and the ability to handle substantial combined loads from any direction.
Precision & Speed: The P4A tolerance class ensures minimal runout and vibration, which is critical for precision applications. The lightweight phenolic cage is optimized for high-speed performance and stability.
Sealed & Pre-Lubricated: As a sealed bearing pre-lubricated with grease, it is protected from contamination and is maintenance-free within its specified temperature range of -30°C to 110°C.
