Summary: Discover the engineering powerhouse behind the 239 Series spherical roller bearings. Designed for ultra-heavy load, low-speed applications where standard bearings fail, this series from Wafangdian JinYu Bearing (WJY) represents the pinnacle of load capacity and reliability for critical industrial machinery.
Where Standard Bearings Reach Their Limit
In heavy industries like mining, cement, and metallurgy, machinery operates under forces that push components to their absolute limits. When conventional spherical roller bearings are insufficient, the 239 Series extra-width spherical roller bearing becomes the essential solution. Engineered not for average duty but for survival under the most severe conditions, this series is the product of specialized design and manufacturing precision.
At Wafangdian JinYu Bearing Manufacturing Co., Ltd. (WJY Bearing), located in the heart of China’s bearing industry, we combine over 6,000 square meters of advanced facilities, RMB 60 million in assets, and the expertise of 46 senior engineers to produce bearings that define reliability. The 239 Series is a testament to our commitment to solving the most demanding load-bearing challenges.
Core Advantages of the 239 Series Design
The defining characteristic of the 239 Series is its extra-wide cross-section. This design yields critical benefits for extreme applications:
Maximum Load Capacity
Offers the highest radial load rating among spherical roller bearings, thanks to larger rollers and extended raceways.
Superior Misalignment Compensation
Its spherical design effectively accommodates static and dynamic misalignment caused by heavy loads and housing deflection.
Optimized for Low Speeds
Built for stability and longevity in slow-rotating, high-torque environments where shock loads are prevalent.
Product Range & Configuration
WJY Bearing manufactures a comprehensive range of 239 Series bearings to meet diverse industrial needs, from large to ultra-large bore sizes.
| Series Segment | Bore Range (mm) | Example Models | Standard Configuration |
|---|---|---|---|
| Standard Large Size | 180 – 500 | 23936, 23952, 239/500 | CA/W33, CC/W33, MB/W33 |
| Ultra-Large & Custom | 530 – 1180 | 239/630, 239/800, 239/1060, 239/1180 | CA/W33, MB/W33 (Optimal for strength & stability) |
All configurations feature the standard W33 lubrication groove and holes. Cages include CA (Machined Brass for high speed/heat), CC (Steel Pressed for high strength), and MB (Brass Solid for robust performance).
Critical Application Scenarios
The 239 Series is not a general-purpose bearing. It is deployed at the most critical stress points in machinery:
- Rotary Kiln & Dryer Thrust/Tire Rollers: Supporting the massive weight of the rotating vessel.
- Vertical Roller Mill & Granulator Main Bearings: Handling extreme grinding pressure.
- Large Reclaimer/Stacker Slewing Rings: Enabling rotation under full load in material handling.
- Heavy-Duty Mixer & Agitator Shaft Supports: Resisting severe loads in chemical and mining processes.
- Specialized Rolling Mill & Marine Equipment: Where shock loads and heavy pressures are constant.
