“R8 2RS Ball Bearing: Durable, Sealed Precision for High-Performance Applications”

The **R8 2RS bearing** is a high-precision, deep groove ball bearing with the following specifications and features:

### Dimensions:

– **Inner Diameter**: 12.7 milímetro (0.5 inch)

– **Outer Diameter**: 28.575 milímetro (1.125 inch)

– **Width**: 7.937 milímetro (0.3125 inch)

### Sealing:

– The **2RS** designation means this bearing has two rubber seals (one on each side). These seals help to keep out contaminants like dust and moisture, which makes the bearing suitable for environments where cleanliness is important. The sealed design also ensures the grease inside stays in place, reducing the need for maintenance.

### Material:

– The **R8 2RS** bearing is typically made from **chrome steel** (SAE 52100), which is known for its durability, high hardness, and resistance to wear. This material ensures the bearing can handle both high loads and speeds over an extended period.

### Lubrificação:

– **Pre-lubricated with grease**, the R8 2RS is ready for use and does not require additional lubrication after installation. The seals ensure the lubricant remains in place for the life of the bearing, making it a low-maintenance option.

### Load Capacity:

– **Dynamic Load Rating**: ~3,000 N (Newtons)

– **Static Load Rating**: ~1,500 N

### Speed:

– The rubber seals may slightly reduce the maximum speed of the bearing compared to open designs, but the R8 2RS can still handle significant revolutions, typically up to **15,000 RPM**, depending on the application and lubrication.

### Applications:

– The **R8 2RS** is widely used in various industrial and mechanical applications, including:

  – Small electric motors

  – Hobby and RC equipment

  – Conveyor systems

  – Power tools

  – Gearboxes

  – Automotive components

The bearing’s sealed, pre-lubricated design makes it suitable for conditions where long-lasting performance is required without frequent maintenance. Its deep groove structure allows it to handle both **radial** and **light axial loads**, adding to its versatility across different applications.
