S7005 CE/HCP4BVG275 Bearing Product Overview & Core Advantages
The S7005 CE/HCP4BVG275 is a high-precision angular contact ball bearing designed for applications demanding exceptional speed, rigidity, and accuracy. Engineered to accommodate combined loads (radial and axial) simultaneously, its compact design and P4 (ABEC-7) tolerance class make it ideal for high-reliability, high-speed machinery. The use of ceramic balls significantly reduces friction and heat generation, enabling superior performance under demanding conditions.
S7005 CE/HCP4BVG275 Bearing Model Code Explained, Specifications & Naming Convention
The model number S7005 CE/HCP4BVG275 provides detailed technical specifications:
- S: Denotes a bearing with a 15° contact angle.
- 7005: Standard size designation for a bearing with a 25mm bore, 47mm outside diameter, and 12mm width.
- CE: Indicates the use of Hybrid Ceramic components (Silicon Nitride balls).
- HC: Specifies the Phenolic Resin (Polyamide) cage material.
- P4: Identifies the super-precision tolerance class (ABEC-7).
- BVG275: Code for the specific high-performance grease and lubrication filling.
S7005 CE/HCP4BVG275 Bearing Structural Features & Performance Benefits
The structural design of the S7005 CE/HCP4BVG275 delivers distinct performance advantages:
- High-Speed Capability: The combination of a lightweight phenolic cage, ceramic balls, and optimized lubrication enables a very high limiting speed of 56,000 rpm.
- High Rigidity & Load Capacity: The angular contact design and precision construction provide excellent stiffness, effectively handling combined radial and axial loads.
- Reduced Friction & Heat: Ceramic balls are harder, lighter, and smoother than steel, leading to lower operating temperatures and extended service life.
- Sealed & Lubricated for Life: As a sealed bearing pre-lubricated with high-performance grease, it is protected from contamination and is maintenance-free within its specified temperature range (-30°C to 110°C).
S7005 CE/HCP4BVG275 Bearing Typical Application Areas
This high-performance bearing is suited for demanding applications across various industries, including:
- High-Speed Machine Tool Spindles
- Precision Medical & Dental Equipment
- Aerospace Actuators & Instrumentation
