6215-2RS1/C3MTF1 Bearing Product Overview & Core Advantages
The 6215-2RS1/C3MTF1 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Its primary advantage lies in its ability to efficiently handle radial loads while offering robust, sealed construction for long-term reliability. The bearing features a C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. Manufactured from high-grade chrome steel for both rings and balls, it ensures durability and consistent operation within a temperature range of -30°C to 120°C. This model is an ideal choice for scenarios requiring a reliable, sealed bearing with a high dynamic load rating of 15,152 lbf.
6215-2RS1/C3MTF1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Advantage |
|---|---|---|
| 6215 | Basic Bearing Series & Size | Denotes a single row deep groove ball bearing with a 75mm bore, 130mm OD, and 25mm width. |
| 2RS1 | Contact Seals on Both Sides | Provides superior protection against contamination and retains lubricant effectively, enhancing service life in dirty environments. |
| C3 | Greater than Normal Radial Internal Clearance | Accommodates thermal expansion from high speeds or interference fits, preventing premature failure due to excessive preload. |
| MTF1 | Factory-Filled Grease (Lithium Soap Complex) | Ensures immediate, optimal lubrication upon installation, reducing maintenance needs and providing reliable operation from the start. |
6215-2RS1/C3MTF1 Bearing Structural Features & Performance Benefits
The 6215-2RS1/C3MTF1's performance is derived from its robust construction. The single row deep groove raceways are precision-ground to handle high radial dynamic loads. The inclusion of contact seals (2RS1) on both sides is a critical feature, providing an effective barrier against contaminants like dust and moisture, which is vital for maintaining performance in harsh conditions. The C3 clearance is a key performance differentiator, offering operational stability in applications prone to thermal expansion. Combined with the factory-applied MTF1 grease, this bearing is effectively pre-lubricated and sealed for life in many applications, minimizing maintenance requirements. The chrome steel cage ensures smooth operation and guides the balls accurately, contributing to the bearing's reliability and limiting speed of 4,800 rpm.
6215-2RS1/C3MTF1 Bearing Typical Application Areas
This bearing's combination of a high load rating, sealed design, and ready-to-use lubrication makes it suitable for a wide range of industrial machinery. Typical applications include:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Pumps and Compressors
