7017 CE/HCP4ADGA Bearing Product Overview & Core Advantages
The 7017 CE/HCP4ADGA is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This universal matchable bearing features a 15° contact angle and an extra light preload (Class A), making it ideal for spindle arrangements where high rigidity and minimal deflection are critical. Its open design, combined with ceramic balls and a phenolic cage, enables superior high-speed performance up to 28,000 rpm. Engineered to accommodate combined radial and axial loads, this bearing delivers outstanding operational reliability in precision machinery.
7017 CE/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
- 7017: Basic bearing series with 85mm bore, 130mm OD, 44mm width
- C: 15° nominal contact angle
- E: Optimized internal design for high-speed operation
- HC: Hybrid Ceramic (steel rings with ceramic balls)
- P4A: High precision tolerance class (superior to ABEC 7)
- DGA: Universal matchable bearing set designation
7017 CE/HCP4ADGA Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and silicon nitride ceramic balls significantly reduces friction, heat generation, and wear, while providing excellent electrical insulation properties. This construction enables higher limiting speeds and extended service life.
Precision Engineering: Manufactured to P4A tolerance class, this bearing ensures minimal runout and vibration, crucial for applications requiring extreme rotational accuracy. The extra light preload eliminates internal clearance while maintaining low operating temperatures.
High-Speed Capability: The phenolic resin cage offers excellent strength-to-weight ratio and smooth operation at high velocities, contributing to the bearing's impressive 28,000 rpm limiting speed.
Universal Matching Design: As a Universal Matchable (SU) bearing, it can be mounted in various preload configurations (DB, DF, DT) without requiring selective matching, simplifying installation and maintenance.
