Henan San Kuang Machinery Technology Co., Ltd. is a professional manufacturer specializing in high-performance slewing bearings for heavy-duty applications. Our IP65 Sealed Double Row Roller Slewing Bearing with an outer diameter of 1.5m is engineered to meet the rigorous demands of crane operations, offering exceptional load capacity, durability, and environmental protection. With over 10,000 square meters of factory space and a dedicated team of 51–100 skilled employees, we integrate advanced manufacturing processes to deliver bearings that excel in harsh conditions. This product combines a robust double-row roller design with an IP65-rated sealing system, ensuring reliable performance even in dusty, wet, or outdoor environments.
The bearing is designed to handle both axial and radial loads simultaneously, making it ideal for tower cranes, mobile cranes, and port machinery. Its 1.5m outer diameter provides a large rotational diameter, while the double-row roller arrangement enhances stability and load distribution. Each unit undergoes rigorous quality control, including hardness testing, dimensional inspection, and sealing performance verification, to meet international standards. Our commitment to quality is reflected in our certifications, including ISO9001, ISO14000, OHSAS18001, TL900, and SA8000 among others, ensuring that every bearing delivers consistent performance.

| Parameter | Value |
|---|---|
| Outer Diameter | 1500 mm (1.5 m) |
| Inner Diameter | Customizable (typically 1000–1200 mm) |
| Overall Height | 90–120 mm (depending on gear option) |
| Dynamic Axial Load Capacity | ~800 kN (calculated per design) |
| Dynamic Radial Load Capacity | ~500 kN |
| Tilting Moment Capacity | ~1200 kN·m |
| Weight | Approx. 350–450 kg (depending on gear) |
| Sealing Type | IP65 (double lip seal + O-ring) |
The double-row roller design distributes load evenly across two rows of rollers, reducing stress concentration and increasing fatigue life. The IP65 seal is achieved through a combination of a high-quality rubber lip seal and an O-ring, preventing contaminants from entering the raceway. This is particularly beneficial for cranes operating in coastal areas, shipyards, or construction sites with high dust levels. The bearing also features grease nipples for easy maintenance and relubrication, ensuring consistent performance over time.
For crane applications, the bearing can be supplied with either an internal gear (for swing drive pinion) or an external gear (for direct drive). The teeth are induction-hardened to HRC 50-55 for wear resistance. We can also customize the mounting hole pattern to match your existing structure, making replacement straightforward. All bearings are supplied with a certificate of conformity and test reports upon request.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum load capacity of this 1.5m slewing bearing?
A: The dynamic axial load capacity is approximately 800 kN, dynamic radial load around 500 kN, and tilting moment up to 1200 kN·m. Exact values depend on the specific gear and mounting configuration; we can provide a detailed calculation based on your application. -
Q: Can this bearing be used in high-temperature environments?
A: The standard temperature range is -20°C to +80°C. For higher temperatures (up to 150°C), we can use special high-temperature grease and seals. Please inform us of your operating conditions. -
Q: Is the IP65 seal suitable for underwater use?
A: IP65 is designed for protection against low-pressure water jets and dust, but it is not intended for continuous submersion. For underwater applications, we recommend a higher IP rating (e.g., IP68) which can be customized. -
Q: How often should I relubricate the bearing?
A: Under normal crane operation, relubrication every 3–6 months is recommended. The bearing has grease nipples for easy access. Use lithium-based grease with EP additives. -
Q: Can I get the bearing with a phosphating or anti-corrosion coating?
A: Yes, we offer optional surface treatments such as phosphating, zinc plating, or epoxy coating for enhanced corrosion resistance. These are particularly useful for marine environments. -
Q: What is the lead time for this bearing?
A: Standard lead time is 30–45 days after order confirmation. Custom designs may require 45–60 days. We can expedite for urgent orders upon request. -
Q: Do you provide installation support or technical drawings?
A: Yes, we provide 2D and 3D CAD drawings upon request. Our technical team can also offer guidance for installation and maintenance to ensure optimal performance. -
Q: How do I ensure the bearing matches my existing crane?
A: We require your mounting hole dimensions, gear parameters (if needed), and load specifications. Our engineers will verify compatibility and propose adjustments if necessary.
