608-2RSH/GJN Bearing Product Overview & Core Advantages
The 608-2RSH/GJN is a sealed single row deep groove ball bearing designed for reliable performance in demanding applications. This precision bearing excels at handling radial loads while offering protection against contamination. Its compact design, featuring a 8 mm bore diameter and 22 mm outside diameter, makes it ideal for applications where space is limited and high reliability is required. The combination of sealed construction and high-quality materials ensures consistent operation and extended service life.
608-2RSH/GJN Bearing Model Code Explained, Specifications & Naming Convention
- 608: Basic model number denoting a standard deep groove ball bearing with 8mm bore, 22mm OD, and 7mm width.
- 2RSH: Designates double rubber seals on both sides. The "H" suffix indicates a high-temperature resistant sealing material, offering superior protection against contaminants and moisture retention.
- GJN: Specifies a low-noise, low-torque grease filling. This pre-lubrication facilitates quiet operation and is suitable for the specified temperature range.
608-2RSH/GJN Bearing Structural Features & Performance Benefits
Robust Sealing for Enhanced Reliability: The double rubber seals (2RSH) effectively shield the internal components from dust, dirt, and other contaminants, while also retaining the lubricant. This design significantly increases bearing life in unclean environments and contributes to its maintenance-free characteristics.
Optimized for Smooth Operation: The bearing is pre-lubricated with a specialized low-noise grease (GJN), which minimizes friction and torque, enabling quiet running and contributing to a limiting speed of 34,000 rpm.
High-Quality Construction: Manufactured from chrome steel for both rings and balls, this bearing provides high strength and durability. The ABEC 1 (ISO P0) tolerance class and standard CN radial internal clearance ensure consistent and reliable performance for a wide range of general-purpose applications.
608-2RSH/GJN Bearing Typical Application Areas
This versatile bearing is commonly found in:
- Electric Motors and Small Gearboxes
- Office Machinery and Computer Cooling Fans
- Conveyor Systems and Material Handling Equipment
- Medical Devices and Precision Instruments
- Power Tools and Household Appliances
