6305-2Z/C3GJN Bearing Product Overview & Core Advantages
The 6305-2Z/C3GJN is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This metric bearing excels at handling radial loads and offers high operational reliability. Its key advantages include a shielded design (2Z) for effective contamination exclusion and a C3 radial internal clearance suitable for applications with thermal expansion or heavy loads. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent precision and is an ideal choice for general industrial machinery requiring robust and durable ball bearing solutions.
6305-2Z/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
- 6305: Basic model number denoting a single row deep groove ball bearing with a 25mm bore, 62mm OD, and 17mm width.
- 2Z: Designates non-contact shields on both sides. This provides effective protection against solid contaminants while maintaining low friction and high-speed capability.
- C3: Indicates a greater radial internal clearance than the Normal (CN) group. This is beneficial for applications involving thermal expansion, heavy loads, or where interference fits are used.
- GJN: Signifies the bearing is pre-lubricated with a high-quality polyurea-based grease. This grease offers a wide operating temperature range (-30°C to +120°C) and provides long-term lubrication for the bearing's service life.
6305-2Z/C3GJN Bearing Structural Features & Performance Benefits
The single row deep groove geometry with high-grade chrome steel rings and balls ensures high dynamic load rating (4631 lbf) and reliable operation. The shielded (2Z) construction protects the internal components from dust and debris, significantly extending service life without the need for re-lubrication. The combination of C3 clearance and pre-lubrication with GJN grease makes this bearing exceptionally robust for applications subject to thermal gradients or demanding load conditions. The ABEC 1 precision guarantees smooth running and low vibration, contributing to the overall efficiency of the machinery.
