7007 ACE/HCP4BVG275 Bearing Product Overview & Core Advantages
The 7007 ACE/HCP4BVG275 is a single-row angular contact ball bearing engineered for high-precision and high-speed applications. Its design is optimized to handle significant combined loads (radial and axial) simultaneously, with a defined 25° contact angle providing excellent axial load capacity. Manufactured to P4 (ABEC-7) tolerance class, this bearing ensures exceptional running accuracy and rotational stability. The use of ceramic balls and a phenolic cage contributes to reduced friction, lower operating temperatures, and superior performance at the specified limiting speed.

7007 ACE/HCP4BVG275 Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls (Si3N4) significantly reduces friction and wear, enabling higher limiting speeds (36,000 rpm) and extended service life. Ceramic balls are also electrically insulating and less susceptible to thermal expansion.
- Phenolic Resin Cage: This lightweight and robust cage material offers excellent dimensional stability at high speeds and provides superior guidance for the ceramic balls, contributing to smooth and quiet operation.
- High-Precision P4 Grade: Manufactured to ultra-precise P4 (ABEC-7) tolerance class with tight dimensional control on the bore diameter (35 mm), outside diameter (62 mm), and width (14 mm), ensuring minimal runout and vibration for demanding applications.
- Optimized Load Capacity: The 25° contact angle is engineered to handle substantial axial loads in one direction while supporting radial loads, making it ideal for applications with combined loads.
- Pre-lubricated for Immediate Use: Comes pre-filled with a high-performance grease (VG275) suitable for a wide temperature range of -30°C to 110°C, ensuring immediate startup and reliable operation.
7007 ACE/HCP4BVG275 Bearing Typical Application Areas
