Reduce Downtime in Agricultural & Construction Machinery with Deep Groove Ball Bearing 6404
Agricultural and construction operations face costly downtime when bearings fail prematurely. Equipment like harvesters and excavators rely on bearings that can handle heavy loads, dust, and variable operating conditions. Many buyers struggle with inconsistent quality from low-cost suppliers, leading to frequent replacements and lost productivity.
Deep Groove Ball Bearing 6404: Built for Heavy-Duty Applications
Our Deep Groove Ball Bearing 6404 is engineered to address these challenges. With dimensions 20x47x14mm and precision ratings from P0 to P4, it delivers reliable performance in agricultural and construction machinery. As an integrated manufacturer with ISO9001 and ISO14001 certifications, we ensure consistent quality through rigorous R&D and QC processes. Whether you need standard bearings or custom solutions, our 1pc MOQ and 3-5 day sample lead time support flexible ordering.
Optimal Performance in Demanding Work Environments
This 6404 Bearing excels in heavy-load radial applications common in agricultural and construction equipment. Its single-row design and 0° contact angle provide efficient load distribution, while Z2V2 vibration grade ensures smooth operation even at high speeds. Constructed from high-quality bearing steel, it withstands the dust, moisture, and temperature variations typical in outdoor machinery, reducing the risk of unexpected failures during critical operation periods.
Key Technical Features That Matter
The precision rating of this ball bearing directly impacts equipment performance. P0-P4 grades allow customization based on application needs—P4 for high-precision machinery requiring minimal runout, and P0 for cost-effective general use. Vibration levels (Z1V1 to Z3V3) are critical for reducing noise and extending bearing life; Z2V2 offers an ideal balance for most agricultural and construction applications. The unseparated, non-aligning design simplifies installation and maintenance, ensuring quick replacements when needed.
Why Quality Bearings Lower Total Operating Costs
Choosing low-quality bearings may seem economical initially, but the hidden costs add up. Premature failures lead to equipment downtime, repair labor, and potential damage to adjacent components. Our 6404 Bearing, backed by a 12-month global warranty, reduces these risks. With strict quality control and defect replacement policies, we help you avoid the costs of frequent replacements and unplanned downtime, ultimately lowering your total cost of ownership.
