629-2RSH/C3 Bearing Product Overview & Core Advantages
The 629-2RSH/C3 is a metric single row deep groove ball bearing designed for reliable performance in demanding applications. This sealed bearing excels at handling primarily radial loads while offering robust operation. Its key advantages include a high limiting speed of 28,000 rpm, a generous C3 radial internal clearance for thermal expansion in high-speed or varying temperature environments, and pre-lubrication for maintenance-free service. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent precision and reliability.
629-2RSH/C3 Bearing Model Code Explained, Specifications & Naming Convention
The model number 629-2RSH/C3 provides detailed technical specifications:
- 629: Basic bearing series, indicating a metric deep groove ball bearing with a 9mm bore.
- -2RSH: Signifies the bearing features two contact seals (RSH type) on both sides. These NBR seals provide superior protection against contamination and effective grease retention.
- /C3: Denotes a greater than normal radial internal clearance. This is critical for applications with significant thermal expansion or where shaft fits may cause clearance reduction.
629-2RSH/C3 Bearing Structural Features & Performance Benefits
- Robust Sealing & Maintenance-Free Operation: The 2RSH contact seals effectively shield the bearing internals from contaminants like dust and moisture, while retaining the factory-applied lubricant. This design ensures long service life without the need for re-lubrication.
- Optimized for High-Speed Applications: The combination of a deep groove raceway, precision-ground chrome steel components, and C3 clearance allows this bearing to operate smoothly at its high limiting speed of 28,000 rpm.
- High Load Capacity & Durability: Constructed entirely from chrome steel (rings, balls, and cage), the bearing offers a high dynamic load rating of 873 lbf and a static load rating of 357 lbf, ensuring durability under significant radial stress.
- Wide Operating Temperature Range: Suitable for use in environments from -30°C to 120 °C, making it versatile for various industrial conditions.
629-2RSH/C3 Bearing Typical Application Areas
This versatile bearing is ideally suited for a wide range of applications requiring high-speed, reliable, and maintenance-free operation, including:
- Electric Motors and small spindle drives
- Power Tools and handheld appliances
- Industrial Fans and blowers
- Conveyor System rollers and idlers
- Automotive Auxiliary Units (e.g., alternators, water pumps)
- Medical Equipment and office machinery
