6216-2RSJEM Bearing Product Overview & Core Advantages
The 6216-2RSJEM is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This metric sealed bearing excels at handling primarily radial loads while offering robust performance. Its key advantages include a high radial dynamic load rating of 16,344 lbf, a standard ABEC 1 | ISO P0 tolerance for consistent operation, and integrated sealing for enhanced service life. The compact design and chrome steel construction throughout ensure high durability and dependable performance in a wide operating temperature range.
6216-2RSJEM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6216 | Basic Bearing Series & Size | Indicates a single row deep groove ball bearing with an 80 mm bore, 140 mm OD, and 26 mm width. |
| 2RS | Contact Seals on Both Sides | Provides superior protection against contaminants and retains lubricant effectively. |
| J | Pressed Steel Cage | Offers a good balance of strength, low weight, and cost-effectiveness for the limiting speed. |
| EM | Electrically Insulated Version | Features a coating on the outer ring to prevent damage from electric currents, enhancing bearing life in electrified environments. |
6216-2RSJEM Bearing Structural Features & Performance Benefits
The 6216-2RSJEM is engineered for performance and longevity. Its single row deep groove raceway is optimized for smooth operation under radial loads. The contact seals (2RS) are a critical feature, providing a robust barrier against dust, moisture, and other contaminants, which is vital for maintaining performance in harsh conditions. The pressed steel cage (J) ensures stable ball guidance, contributing to the bearing's ability to achieve its specified limiting speed of 4,500 rpm. The electrically insulated outer ring (EM) is a key performance benefit, protecting the bearing from electrical erosion caused by stray currents, a common cause of premature failure in motors and generators. Manufactured entirely from chrome steel, this bearing offers high strength and wear resistance.
6216-2RSJEM Bearing Typical Application Areas
The combination of sealing, electrical insulation, and robust load capacity makes the 6216-2RSJEM ideal for a range of industrial applications. It is commonly specified in:
- Electric Motors and Generators (benefiting from the EM insulation)
- Industrial Fans and Blowers
- Conveyor Systems
- Agricultural Machinery
- Material Handling Equipment
Its design is well-suited for applications where environmental protection and protection against electrical damage are critical for operational reliability.
