Case Details
Wire Raceway Bearing, also known as Wire Race Bearing, is a special slewing bearing component that adopts precision hardened steel wire as the raceway carrier embedded in lightweight support rings. Different from traditional solid-race bearings, its load is directly borne by high-strength wire raceways, and the support structure can be made of lightweight materials such as aluminum alloy and titanium alloy. It has five core advantages: lightweight, ultra-compact, high load-bearing capacity, extreme environment resistance, and high-precision rotation:
- Extreme Lightweight: The overall weight is 40%-60% lighter than solid-race bearings of the same specification, significantly reducing the mobile load and energy consumption of military equipment;
- Ultra-compact Structure: With an extremely thin cross-section, the installation space is only 1/2-2/3 of traditional bearings, suitable for the limited cabin layout of military equipment;
- Multi-dimensional High Load Capacity: Single/double/triple-row wire raceway design, capable of withstanding axial, radial loads and tilting moments simultaneously, meeting composite stress scenarios such as turrets and radars;
- Extreme Environment Adaptability: Operating temperature ranges from -40℃ to +100℃, with shock resistance, vibration resistance and corrosion resistance, adapting to complex battlefield environments such as deserts, cold regions and oceans;
- High Precision & Long Service Life: Precision-ground wire raceways matched with low-friction rolling elements achieve micron-level rotation accuracy, low wear and easy maintenance. Some models can be reused by flipping, reducing logistics support costs.
