As a leading manufacturer based in Luoyang, Henan, China, Henan San Kuang Machinery Technology Co., Ltd. specializes in high-performance components for heavy industrial equipment. Our Through-Hardened Ball Mill Trunnion Bearings with 60HRC Surface Hardness are engineered to withstand extreme loads and abrasive environments, delivering exceptional durability and operational efficiency. With a factory spanning 10,000-30,000 square meters and a dedicated team of 51-100 skilled professionals, we combine precision manufacturing with rigorous quality control to ensure every bearing meets the highest standards.
These trunnion bearings are designed specifically for ball mills used in mining, cement, and mineral processing industries. The through-hardening process ensures uniform hardness throughout the entire bearing cross-section, while the 60HRC surface hardness provides outstanding wear resistance and extended service life. Below, we detail the key features, technical specifications, and benefits that make our bearings a reliable choice for demanding applications.
Key Features
- Through-Hardening Process: Ensures consistent hardness from core to surface, preventing localized softening and reducing the risk of failure under high stress.
- 60HRC Surface Hardness: Provides exceptional resistance to abrasive wear, extending bearing life by up to 30% compared to conventional hardened bearings.
- High Load Capacity: Designed to support heavy radial and axial loads typical in ball mill operations, with a load rating of up to 500 tons per bearing.
- Precision Machining: Manufactured to tight tolerances (ISO IT6-IT7) for smooth rotation and minimal vibration, enhancing mill performance.
- Customizable Dimensions: Available in a wide range of sizes (outer diameter from 500mm to 2000mm) to fit various ball mill models.
- Superior Lubrication Channels: Integrated grooves and holes for efficient grease or oil distribution, reducing maintenance intervals.
- Corrosion Resistance: Optional anti-corrosion coating for harsh environments, such as wet grinding processes.

Frequently Asked Questions
-
Q: What is the difference between through-hardened and case-hardened bearings?
A: Through-hardened bearings have uniform hardness throughout the entire cross-section, while case-hardened bearings only have a hardened outer layer. Through-hardening provides better resistance to high-stress applications and eliminates the risk of core softening under heavy loads. -
Q: How does the 60HRC surface hardness benefit my ball mill?
A: The high surface hardness (60HRC) significantly reduces wear from abrasive materials like ore and grinding media, extending bearing life and reducing replacement frequency. This directly translates to lower maintenance costs and higher uptime. -
Q: Can you provide custom sizes for my specific ball mill model?
A: Yes, we offer customizable dimensions (outer diameter, width, inner diameter, and bolt patterns) to fit various mill models. Please provide your original drawings or specifications, and we will engineer a solution. -
Q: What lubrication system do you recommend for these bearings?
A: For most ball mill applications, we recommend automatic grease lubrication with a centralized system. However, oil lubrication is also available upon request. Our design includes optimized lubrication channels to ensure even distribution. -
Q: How long is the typical lead time for an order?
A: Standard sizes (outer diameter up to 1000mm) typically ship within 30-45 days. Custom orders may require 45-60 days depending on complexity. We can also expedite urgent orders based on current production capacity. -
Q: Do you provide after-sales technical support?
A: Absolutely. Our team offers remote technical support for installation, troubleshooting, and maintenance. For larger projects, we can also arrange on-site assistance upon request. -
Q: What quality inspections are performed on each bearing?
A: Each bearing undergoes 100% inspection including hardness testing (Rockwell), dimensional checks (CMM), ultrasonic testing for internal defects, and surface finish verification. We also provide a test report with every shipment. -
Q: Can these bearings be used in wet grinding environments?
A: Yes, we offer optional anti-corrosion coatings (e.g., zinc-nickel plating or epoxy coating) to protect against moisture and chemical exposure. Please specify your operating conditions when ordering.
