Key Features & Benefits
- Dustproof Design: The double-lip rubber seal effectively blocks dust, dirt, and moisture, which is critical for combine harvesters operating in fields with heavy chaff and soil. This reduces maintenance frequency and extends bearing life by up to 30% compared to standard bearings.
- Vibration Dampening: The natural rubber outer layer absorbs shocks and vibrations from the harvester’s moving parts, protecting the shaft and surrounding components. Operators experience smoother operation and less noise.
- Corrosion Resistance: Chrome steel inner ring is treated with anti-rust coating, while the rubber provides additional protection against agricultural chemicals and moisture.
- Easy Installation: Designed to fit standard 35mm shafts, this bearing can be quickly replaced without special tools. Drop-in replacement for many popular combine models.
- High Load Capacity: With a dynamic load rating of 10 kN, it can handle the heavy radial and axial loads typical of grain harvesting and threshing mechanisms.
- Wide Compatibility: Suitable for various combine harvester brands and models, including John Deere, Case IH, New Holland, Claas, and others. Customizable dimensions available upon request.

Frequently Asked Questions (FAQ)
Q1: Is this bearing compatible with my specific combine harvester model?
A: This bearing is designed for standard 35mm shafts and fits many popular combine harvester models. We recommend checking the shaft diameter and housing dimensions. If you need a custom size, please provide your requirements, and we can produce a tailored solution.
Q2: How does the dustproof design work?
A: The bearing features a double-lip rubber seal that contacts the inner ring, creating a barrier against particles. The rubber material is flexible yet durable, maintaining sealing effectiveness even under high-speed rotation and temperature changes.
Q3: What is the expected lifespan of this bearing?
A: Under normal operating conditions (clean environment, proper lubrication, loads within rated capacity), the bearing can last 2,000-3,000 operating hours. The dustproof design significantly extends life in dusty environments compared to open bearings.
Q4: Do you offer samples before bulk order?
A: Yes, we provide samples for evaluation. Please contact our sales team to discuss sample availability and shipping costs. We can also produce custom samples based on your specifications.
Q5: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is typically 100 pieces. For custom designs, MOQ may vary. We are flexible and can discuss based on your project needs.
Q6: Can I get a certificate of quality or material test report?
A: Yes, we can provide a material certification and test report upon request. Our quality control process ensures each batch meets specified standards.
Q7: How do you package the bearings for export?
A: Bearings are individually wrapped in anti-rust paper, then packed in cartons with foam inserts to prevent movement. For bulk orders, we use wooden pallets and shrink wrap for ocean freight. Custom packaging is available.
Q8: What is the typical lead time?
A: For standard bearings, lead time is 15-20 days after order confirmation. Custom orders may require 25-35 days. We always confirm exact lead time in the quotation.
