S7016 ACD/HCP4A Bearing Product Overview & Core Advantages
The S7016 ACD/HCP4A is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. Designed to accommodate combined loads (simultaneous radial and axial loads), this bearing features a 25° contact angle for superior axial load capacity. Its P4 (ABEC-7) tolerance class ensures ultra-precise rotational accuracy, while the combination of a phenolic cage and ceramic balls contributes to high-speed capability and low heat generation. Pre-lubricated and sealed, it offers a compact, high-rigidity solution for high-reliability machinery.
S7016 ACD/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| ACD | Angular Contact, 25° Contact Angle | Optimized for handling significant axial loads in one direction. |
| HC | Hybrid Ceramic (Ceramic Balls, Steel Rings) | Enables higher limiting speeds, reduced friction, and longer service life. |
| P4A | P4 (ABEC-7) Precision Class | Guarantees extremely tight dimensional and running accuracy for precision applications. |
S7016 ACD/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The use of ceramic balls with steel rings significantly reduces centrifugal forces, allowing for a limiting speed of 12,000 rpm. This construction also provides superior electrical resistance and operates effectively with less lubrication.
- Phenolic Resin Cage: The lightweight and robust phenolic cage offers excellent dimensional stability at high speeds, contributing to smooth operation and reduced vibration.
- Preload & High Rigidity: This bearing is supplied with a preload, which eliminates internal clearance. This results in high system rigidity, precise shaft positioning, and reduced noise levels.
- Sealed & Pre-Lubricated: The integral seals protect against contamination and retain lubricant, making the bearing ready for installation and suitable for maintenance-free operation within its specified temperature range.
- High Load Capacity: With a dynamic load rating of 14,040 lbf and a static load rating of 13,162 lbf, it is built to withstand demanding combined load conditions.
