1. Product Overview
6005-ZZ is a single-row deep groove ball bearing with double metal shields (ZZ), manufactured to ISO standard dimensions of 25×47×12mm. Made of high-purity GCr15 chrome bearing steel with P6 precision grade, this bearing delivers low noise (Z3V3) and smooth, stable rotation. The double-sided metal shield design effectively blocks dust, dirt and fine particles while retaining the factory-filled lubricating grease inside. Pre-lubricated and maintenance-free, the 6005-ZZ bearing is a versatile general-purpose component widely used in medium-speed industrial transmission and material handling equipment.
2. Core Product Features
- P6 Precision Grade: ABEC-3 tolerance class ensures accurate shaft alignment, stable running and long equipment service life.
- Z3V3 Low Noise Level: Optimized internal raceway and super-finished rolling surfaces minimize vibration and noise for quiet operation.
- Double ZZ Metal Shield Protection: Non-contact steel shields prevent dust and debris ingress and avoid grease leakage in ordinary workshop environments.
- High Speed Capability: Supports up to 13,000 r/min with grease lubrication and 17,000 r/min with oil lubrication.
- Strong Load Capacity: Dynamic load rating of 10.1 kN and static load rating of 5.85 kN handle radial and light axial loads reliably.
- Premium Material & Long Durability: High-purity GCr15 chrome bearing steel with overall heat treatment delivers high hardness, wear resistance and fatigue strength.
- Maintenance-Free & Cost-Effective: Factory pre-lubricated with high-grade grease, reducing downtime and maintenance costs.
