Product Overview: The HK 3520 Drawn Cup Needle Roller Bearing
The HK 3520 is a high-performance drawn cup needle roller bearing with an open-end design, featuring a 35mm bore diameter, 42mm outer diameter, and 20mm width. This bearing is a key component in our Needle Roller Bearings category, specifically within the Drawn Cup Bearings collection. Its unique construction consists of a thin-walled, drawn outer cup and a needle roller and cage assembly. This design provides a very low sectional height, making it an excellent choice for compact and lightweight machinery where radial space is limited but high load-carrying capacity is essential.
As a leading supplier of industrial components, we ensure our HK 3520 bearings meet rigorous industry standards for performance and durability. The open-end configuration allows for shafts to pass through the bearing, making it versatile for a wide range of mounting arrangements. These bearings are typically installed with a tight press fit into the housing, eliminating the need for shoulders or snap rings to locate them axially.
Key Features of the HK 3520 Bearing
- Low Cross-Section: Its minimal radial height allows for significant space and weight savings in machine design.
- High Radial Load Capacity: Despite its compact size, the full complement of needle rollers provides excellent load-carrying capability.
- Drawn Steel Outer Cup: The precision-formed outer ring acts as a raceway for the rollers and allows for simple press-fit installation.
- Open-End Design: Suitable for applications where the shaft extends through the housing bore.
- Cage-Guided Rollers: The cage ensures precise guidance of the needle rollers, enabling reliable operation at high speeds.
- Cost-Effective Solution: Offers a high-performance, economical bearing solution for various industrial and automotive applications.
