What is HK4520 Bearing
2025-08-27The HK4520 bearing is a type of needle roller bearing. The following is an introduction to it from aspects of bearing dimensions, bearing characteristics and bearing applications:
Bearing Dimensions:
- The main dimensional parameters of the HK4520 bearing are: inner diameter 45mm, outer diameter 52mm, and thickness 20mm.
- This exquisite dimensional design endows the HK4520 bearing with an extremely compact radial structure, enabling it to operate efficiently and stably even under working conditions with extremely limited space.
Bearing Characteristics
- Compact Structure:
Made of high-quality thin special steel plates through precision deep drawing processing, the HK4520 bearing adopts a unique structural design, consisting of an outer ring, needle rollers and a needle roller cage. As the product type with the smallest cross-sectional height among rolling bearings with outer rings, it can significantly save installation space, and is especially suitable for design scenarios with strict space requirements.
- Easy Installation:
With an interference fit design, the HK4520 bearing can be directly pressed into the housing to complete the installation without additional axial fixing measures, featuring simplified and efficient operation steps.
- High Load Capacity:
Despite its delicate and compact structural design, it has excellent radial load-bearing performance. The dynamic radial load-carrying capacity of this bearing can reach 27kN, and the static radial load-carrying capacity is as high as 59kN.
- Good Speed Performance:
The maximum speed can reach 3550rpm (grease lubrication) or 5900rpm (oil lubrication), which can meet the application scenarios that have requirements for speed.
- Diverse Forms:
In addition to the common open-end structure, the HK4520 bearing also offers a closed-end design and supports single-sided or double-sided built-in sealing configurations. These diverse structural forms can effectively meet the special needs of different working conditions and application scenarios.
