Low carbon USS flat washers, typically used with Grade 8 or hardened steel bolting, are used under bolt heads or nuts to increase the bearing surface area, or to offer protection so that the nut or bolt can be rotated without distortion of the bearing surface. Flat washers are also used to give tightness to a joint, to prevent leakage, and especially to distribute pressure under the head of a bolt or nut. Dimensional specifications are governed by ASME B18.21.1. USS (United States Standard) flat washers have a larger outer diameter than SAE (Society of Automotive Engineers) flat washers, and can be utilized in nearly any application. ASTM F844 covers the standard specifications for unhardened steel flat washers for general use. Available in zinc plated finish. Zinc plating sacrifices itself, corroding before the base material, offering added corrosion resistance.

For many years, as the general agent of SKF Bearings in China, we have observed that agricultural machinery bearings often face significant challenges. One common issue is the lack of proper sealing, which leads to oil leakage and early failure. This not only reduces productivity for farmers but also impacts their profits. At the same time, original equipment manufacturers (OEMs) are burdened with higher warranty costs and potential damage to customer relationships.
To address these issues, SKF has developed the Agricultural Y-Bearing unit. Designed for tough conditions, this bearing offers a range of advanced features that help prevent such problems. It includes a five-lip seal design, a true concentric locking mechanism, and optional anti-corrosion protection. These innovations ensure better performance, longer service life, and improved reliability.
**Key strengths of SKF Agricultural Y-Bearing:**
- **Extended service life**: Up to 30–50% longer than standard bearings.
- **Improved sealing**: Reduces oil leakage and contamination.
- **Stronger construction**: Built to withstand harsh agricultural environments.
- **Easy installation**: Simplifies assembly and maintenance.
- **Cost-effective**: Lowers long-term repair and replacement costs.
This technology is widely used in various agricultural equipment, including:
- Combine harvesters
- Mower conditioners
- Hay balers
- Rotary tillers
- Grain elevators
- Disc mowers
By using SKF Agricultural Y-Bearings, farmers and OEMs can enjoy greater efficiency, reduced downtime, and better overall performance.
