630/8-2RS1/W64 Bearing Product Overview & Core Advantages
The 630/8-2RS1/W64 is a metric single row deep groove ball bearing engineered for high reliability in compact spaces. Its primary advantage lies in its sealed design and solid oil lubrication, which provides exceptional protection against contamination and ensures long-term, maintenance-free operation. This bearing is designed to handle primarily radial loads and is manufactured to ABEC 1 | ISO P0 precision standards, making it a cost-effective and robust solution for a wide range of industrial applications requiring consistent performance.
630/8-2RS1/W64 Bearing Model Code Explained, Specifications & Naming Convention
- 630: Standard deep groove ball bearing series.
- 8: Bore diameter of 8 mm.
- -2RS1: Designates contact seals on both sides. The "RS1" suffix indicates nitrile rubber (NBR) seals that effectively shield the bearing interior from dust and moisture.
- /W64: Indicates the bearing is pre-lubricated with Solid Oil. This is a polymer matrix saturated with lubricant, offering superior retention and longer service life compared to traditional greases, especially in challenging environments.
630/8-2RS1/W64 Bearing Structural Features & Performance Benefits
Robust Sealing & Lubrication: The combination of 2RS1 contact seals and W64 Solid Oil creates a highly effective barrier against contaminants. This system prevents lubricant washout and ensures reliable operation, making the bearing ideal for applications where re-lubrication is difficult or impossible.
High Load Capacity & Precision: Constructed from chrome steel for both rings and balls, this bearing offers a high radial dynamic load rating of 776 lbf and a radial static load rating of 308 lbf. Manufactured to ABEC 1 (ISO P0) tolerance, it provides smooth and precise rotation.
Optimized Performance: The standard CN radial internal clearance and robust construction support a limiting speed of 22,000 rpm. The solid oil lubrication contributes to stable performance across a wide operating temperature range of -30°C to 120°C.
630/8-2RS1/W64 Bearing Typical Application Areas
This versatile and sealed bearing is commonly specified in:
- Small Electric Motors and Gearboxes
- Office Automation Equipment (e.g., printers, scanners)
- Medical Devices and Low-Power Drive Systems
- Food Processing Machinery (where sealed units are advantageous)
- Ventilation Fans and Pumps
