7009 CE/HCP4BVG275 Bearing Product Overview & Core Advantages
The 7009 CE/HCP4BVG275 is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional rotational accuracy and speed capability. This single-row bearing features a 15° contact angle, optimized for supporting combined radial and axial loads in one direction. Its core advantages stem from its P4 (ABEC-7) super-precision tolerance, ceramic ball construction, and phenolic resin cage, which collectively deliver superior high-speed performance, rigidity, and extended service life in critical machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7009 | Basic bearing series, indicating a metric 45 mm bore, 75 mm OD, and 16 mm width. |
| CE | Designates a 15° contact angle and specific internal geometry optimized for high-speed operation. |
| HC | Indicates the use of Hybrid Ceramic balls (Silicon Nitride), offering reduced weight, lower friction, and superior performance at high speeds. |
| P4 | Specifies the tolerance class P4 (ABEC-7), denoting extremely tight dimensional and running accuracy for precision applications. |
| BVG275 | Likely refers to a specific preload level (Available) and lubrication type (Lubricated) as per manufacturer's internal coding. |
7009 CE/HCP4BVG275 Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The use of ceramic balls significantly reduces centrifugal forces, lowers operating temperature, and enables a limiting speed of 32,000 rpm. This construction also provides excellent electrical insulation and corrosion resistance.
- High Rigidity & Load Capacity: The 15° contact angle and single-row matched arrangement provide high rigidity and are capable of handling significant combined radial and axial loads (Dynamic: 2925 lbf, Static: 1912 lbf).
- Super-Precision Performance: Manufactured to P4 tolerance class, this bearing ensures minimal runout and vibration, which is critical for maintaining accuracy in high-speed spindles.
- Phenolic Resin Cage: The lightweight and robust phenolic cage offers excellent dimensional stability and low friction at high speeds, contributing to the bearing's overall high-speed capability and smooth operation.
- Preload & Lubrication: The bearing is supplied with a specific preload and is lubricated for immediate use, ensuring optimal performance from the start of operation.
