6015-2Z/C3 GJN Bearing Product Overview & Core Advantages
The 6015-2Z/C3 GJN is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This shielded bearing is designed to primarily handle radial loads while also accommodating moderate axial loads in both directions. Its key advantages include high operational reliability, a generous C3 radial internal clearance suitable for applications with thermal expansion, and pre-lubrication for long-term, maintenance-free operation. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a cost-effective solution without compromising on essential precision and durability.
6015-2Z/C3 GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| 6015 | Standard bearing series with 75mm bore, 115mm OD, 20mm width. | Defines the core bearing dimensions for interchangeability. |
| 2Z | Non-contact steel shields on both sides. | Provides effective contamination protection while allowing high speeds. |
| C3 | Radial internal clearance greater than Normal (CN) group. | Prevents preload in applications prone to thermal expansion, ensuring smooth operation. |
| GJN | Pre-lubricated with a high-quality, lithium-based grease. | Enables maintenance-free operation for the grease service life, ideal for sealed-for-life applications. |
6015-2Z/C3 GJN Bearing Structural Features & Performance Benefits
Optimized Single Row Design: The deep groove raceway and high-quality chrome steel construction (rings, balls, and cage) provide excellent load carrying capacity and long service life under radial dynamic loads up to 8902 lbf.
Effective Sealing Solution: The 2Z non-contact shields retain the factory-applied grease and protect the bearing interior from dust and other contaminants, significantly enhancing reliability in unclean environments without a significant penalty on the limiting speed (5,600 rpm).
Controlled Internal Clearance: The C3 clearance is a critical feature for applications where bearing seats or shafts heat up, preventing thermal seizure and ensuring consistent performance across the specified temperature range of -30°C to 120°C.
Ready-to-Install Convenience: Being pre-lubricated (GJN), this bearing is delivered ready for immediate installation, reducing assembly time and eliminating the need for initial lubrication.
6015-2Z/C3 GJN Bearing Typical Application Areas
- Electric Motors: A standard choice for motor shafts in industrial fans, pumps, and compressors.
- Material Handling Equipment: Conveyor rollers, pulley systems, and gearboxes.
- Agricultural Machinery: Implemented in tractor accessories, harvesters, and other farm equipment.
- General Industrial Machinery: Used in a wide array of machinery requiring reliable, maintenance-free rotational support.
