6312/VW514 Bearing Product Overview & Core Advantages
The 6312 is a single row deep groove ball bearing designed for exceptional performance in a wide range of industrial applications. Engineered to primarily support radial loads, this open-type bearing is characterized by its high running accuracy, robust construction, and versatility. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures reliable operation and is an ideal choice for applications demanding consistent performance and long service life under standard operating conditions.
6312/VW514 Bearing Model Code Explained, Specifications & Naming Convention
- 6312: Standard designation for a single row deep groove ball bearing with a 60 mm bore, 130 mm outside diameter, and 31 mm width.
- Open (Seal Type): The bearing is supplied without seals or shields, allowing for higher limiting speeds and facilitating easy re-lubrication in service.
- ABEC 1 | ISO P0: Denotes the standard tolerance class, ensuring precise dimensional control for reliable performance.
- CN: Specifies the standard radial internal clearance for normal operating conditions.
- Lubrication: None: The bearing is supplied without grease, providing flexibility for the user to apply a lubricant suitable for the specific application.
6312/VW514 Bearing Structural Features & Performance Benefits
Constructed entirely from high-grade Chrome Steel, including the rings, balls, and cage, the 6312 bearing offers excellent durability and resistance to wear. The deep groove raceway and optimized geometry enable it to handle not only significant radial loads (dynamic: 18,412 lbf, static: 11,735 lbf) but also moderate axial loads in both directions. The open design and robust construction contribute to a high limiting speed of 5,300 rpm, making it suitable for a variety of high-speed applications. Its compliance with ROHS and REACH standards ensures it meets modern environmental and safety regulations.
