6012-2RS1 Bearing Product Overview & Core Advantages
The 6012-2RS1 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with metric dimensions and manufactured to P6 tolerance class, this bearing delivers high precision and reliable operation. Its key advantage lies in its ability to handle significant radial loads efficiently, while also accommodating moderate axial loads in both directions. The sealed construction (2RS1) with pre-lubricated grease ensures long service life and minimal maintenance, making it an ideal choice for applications requiring high reliability and durability.
6012-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
The model number 6012-2RS1 is decoded as follows:
- 60: Series designation, indicating a medium duty bearing with specific dimensional proportions.
- 12: Bore diameter code. The bore diameter is 60 mm (calculated as 12 x 5 = 60mm).
- 2RS1: Sealing suffix. This denotes two contact seals (one on each side) made of Nitrile Rubber (NBR), providing excellent protection against contaminants and effective grease retention.
6012-2RS1 Bearing Structural Features & Performance Benefits
The performance of the 6012-2RS1 is a direct result of its robust construction and material selection.
- High Load Capacity & Rigidity: The single row deep groove raceway geometry is optimized to support high radial dynamic load ratings (6902 lbf) and radial static load ratings (5216 lbf). The use of high-grade chrome steel for both rings and balls ensures dimensional stability under load.
- Sealed & Lubricated for Life: The double-sided contact seals (2RS1) effectively shield the internal components from dust, moisture, and other contaminants. The bearing is pre-filled with grease lubrication, making it maintenance-free for its entire service life in many applications.
- Precision & Speed: Manufactured to a P6 tolerance class, it offers tighter dimensional and running accuracy than standard bearings. Combined with a stainless steel cage, it achieves a high limiting speed of 4,300 rpm, suitable for a wide range of operational requirements.
- Standard Internal Clearance: The CN radial internal clearance is the standard group, making it suitable for most common operating conditions and fits.
