Manufactured to ABEC1 tolerance class, this bearing ensures consistent operation and is an ideal choice for high-volume, cost-sensitive applications requiring dependable performance.
Model Code Breakdown
| Code Element | Technical Meaning |
|---|---|
| 625 | Standard designation for a single row deep groove ball bearing with a 5mm bore, 16mm OD, and 5mm width. |
| Open | No seals or shields, allowing for higher speeds and easy re-lubrication, but requiring a clean operating environment. |
| MC3 | Specifies the radial internal clearance group (0.002mm to 0.013mm), suitable for most general applications. |
625 Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The deep groove raceway and seven high-grade chrome steel balls enable efficient handling of radial dynamic loads up to 331 lbf and static loads up to 122 lbf.
- High-Speed Capability: The lightweight stainless steel cage precisely guides the balls, contributing to a high limiting speed of 36,000 rpm and stable operation.
- Precision & Durability: Manufactured from chrome steel for both rings and balls, the bearing offers high hardness and wear resistance. The ABEC1 precision class ensures running accuracy and low vibration.
- Versatile Operating Range: With a temperature range from -30°C to 110°C, this bearing is suitable for a wide array of environmental conditions.
