608-2Z/C3GJN Bearing Product Overview & Core Advantages
The 608-2Z/C3GJN is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This precision bearing features shielded construction for contaminant protection and is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring reliable operation and dimensional consistency. Its compact design, with an 8 mm bore and 22 mm outside diameter, makes it ideal for applications where space is limited. The bearing is capable of handling primarily radial loads and is pre-set with a C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used.
608-2Z/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
- 608: Basic bearing series, indicating a single row deep groove ball bearing with 8mm bore, 22mm OD, and 7mm width
- 2Z: Designates shielded construction on both sides, providing effective protection against contaminant ingress while allowing higher speeds compared to sealed variants
- C3: Indicates greater radial internal clearance than normal, suitable for applications with thermal expansion or interference fits
- GJN: Specifies the use of a high-performance polyurea grease, offering excellent temperature resistance and extended lubrication life
608-2Z/C3GJN Bearing Structural Features & Performance Benefits
This bearing's construction delivers significant performance advantages. The single row deep groove raceway geometry is optimized for radial load capacity, while the shielded design (2Z) provides effective contaminant exclusion without significantly impacting the limiting speed of 34,000 rpm. The C3 radial clearance accommodates thermal expansion in high-speed applications and interference fits during mounting. Manufactured from chrome steel for both rings and balls, the bearing ensures high durability and wear resistance. The polyurea grease (GJN) provides reliable lubrication across the operating temperature range of -30°C to 120°C, making it suitable for various industrial environments.
608-2Z/C3GJN Bearing Typical Application Areas
The 608-2Z/C3GJN finds extensive use across multiple industries due to its balanced performance characteristics. Common applications include: electric motors and small machinery, power tools, industrial fans and blowers, office equipment such as printers and copiers, medical devices, and various light industrial machinery. Its combination of shielded protection, appropriate internal clearance, and reliable lubrication makes it particularly well-suited for applications requiring maintenance-free operation and consistent performance.
