1215 Bearing Product Overview & Core Advantages
The 1215 is a double row deep groove ball bearing designed for robust performance in demanding applications. This metric bearing features an open design, enabling it to handle significant radial loads with high reliability. Its compact bearing dimensions (75 mm bore, 130 mm OD, 25 mm width) make it an ideal choice for applications where space is at a premium. Manufactured from high-grade chrome steel for both rings and balls, and featuring a stainless steel cage, it offers excellent durability and consistent operation within a wide temperature range of -30° to 110 °C. The bearing is pre-lubricated for immediate use, ensuring a long service life and reduced maintenance needs.
1215 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 1215 | Standard designation for a double row deep groove ball bearing with a 75mm bore diameter and specific dimensional series. |
| Open (Seal Type) | No integral seals or shields. This allows for higher limiting speeds and is suitable for applications where external sealing is provided or where the environment is clean. |
| Lubricated | The bearing is supplied with a factory-applied lubricant, ready for immediate installation and operation. |
1215 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The double row construction provides significantly greater radial load carrying capacity and rigidity compared to single row bearings, making it suitable for applications with heavy loads and minimal deflection requirements.
- Optimized for Speed: The combination of the open design and a precision stainless steel cage enables a high limiting speed of 6,700 rpm, supporting efficient operation in high-speed machinery.
- Durable Construction: Components made from chrome steel offer high hardness and wear resistance, while the stainless steel cage provides excellent corrosion resistance and strength.
- Precision Tolerances: Tight dimensional tolerances on the bore, outside diameter, and width ensure precise fit and reliable performance in precision assemblies.
