6020-2Z/C4S1GJN Bearing Product Overview & Core Advantages
The 6020-2Z/C4S1GJN is a metric single row deep groove ball bearing engineered for superior performance in demanding industrial applications. This shielded bearing is designed to primarily handle radial loads with high efficiency and reliability. Its key advantages include a C4 radial internal clearance for specific operational conditions, a high limiting speed of 4,300 rpm, and robust construction from chrome steel for extended service life. The inclusion of shields (2Z) provides effective contaminant protection, making it a durable and maintenance-friendly solution for a wide range of machinery.
6020-2Z/C4S1GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Advantage |
|---|---|---|
| 6020 | Basic Bearing Number | Denotes a metric, single row deep groove ball bearing with a 100 mm bore and 150 mm outside diameter. |
| 2Z | Shielded on Both Sides | Provides effective protection against solid contaminants, retaining lubrication and enhancing bearing life without the friction of contact seals. |
| C4 | Radial Internal Clearance | Greater than normal clearance (C4 group), suitable for applications with significant thermal expansion or where interference fits are used. |
| S1GJN | Lubrication & Cage Designation | Indicates a specific cage type and that the bearing is supplied without lubrication ("None"), allowing for application-specific greasing. |
6020-2Z/C4S1GJN Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and single row construction provide excellent capability for handling high radial loads, with a dynamic load rating of 13,533 lbf and a static load rating of 12,185 lbf.
- Optimized Internal Clearance: The C4 radial clearance ensures reliable operation in applications prone to thermal expansion or where tight fits are required, preventing premature failure due to excessive preload.
- High-Speed Capability: With a limiting speed of 4,300 rpm, this bearing is suitable for high-speed applications. The combination of the chrome steel cage and shielded design contributes to stable operation at elevated rotational velocities.
- Shielded for Protection: The non-contact shields (2Z) on both sides effectively keep out contaminants like dust and debris while minimizing friction, contributing to a long, maintenance-free operational life.
- Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class, ensuring consistent quality and reliable performance for general precision applications.
6020-2Z/C4S1GJN Bearing Typical Application Areas
