LYHY Slewing Bearing Types CZPT slewing bearings can be divided into the following types as per their structures: single row 4 point contact ball slewing bearing, single row cross roller slewing bearing, double row different ball diameter slewing bearing, three row cylindrical roller slewing bearing and roller/ball combination slewing bearing. And all these types of slewing bearings can be further divided into bearings without gears, bearings with external gears and bearings with internal gears.
Detailed description of these types slewing bearings
Single row 4 point contact ball slewing bearings This kind of slewing bearings can support high dynamic loads, transmitting axial and radial forces simultaneously as well as the resulting tilting moments. Applications of this kind of bearings are hoisting, mechanical handling and general mechanical engineering etc. Single row cross roller slewing bearings This kind of bearings can support combinations of large radial force, medium axial force and tilting moment with small or zero clearance. Main applications of this kind of bearings are hoisting and mechanical handling and general mechanical engineering etc. Double row different ball diameter slewing bearings This kind of bearings can support high static loads with simple structures. They are mainly used in situations with variation load position and direction and continuously rotating. Main applications of this kind of bearings are deck hoisting, mining and material handling etc. Triple row cylindrical roller slewing bearings This kind of bearings has high load carrying capacity. Under same loads, this kind of bearings has much smaller diameters which can make the installation much compact, as different kinds of loads are supported by different races and rollers. Main applications of this kind of bearings are hoisting, mechanical handling, mining and materials handling, offshore technology and general mechanical engineering etc. Roller/ball combination slewing bearings This kind of bearings can support high axial load and low tilting moments.

Production Process of CZPT slewing bearings
Quality Control Process of CZPT slewing bearings
LYHY Slewing Bearing Packing Bearing surface is covered with the anti-rust oil first; and then wrapped with the plastic film; And then packed with kraft paper and professional belts; At last, with wooden box totally at the outer packing to invoid the rust or the moist; We can depend on the customers demand to be packed;
Transportation: All CZPT slewing ring bearings can be usually delivered timely, usual production time is 15-50 days based on different slew bearings diameters, sometimes slew rings will be in stock. Slewing bearings can be offered different delivery terms, such as EXW, FOB, CIF, DDU and so on. Also, slewing rings can be transported by different transport ways, by express (such as DHL, TNT, UPS, FEDEX and so on), by air, by sea, by truck, by railway and so on.
Slewing Ring Bearings——Applications: Slewing ring bearings are widely used in industry and known as “the machine joints” Here under is the specific slewing bearing applications 1. Construction machinery (e.g. cranes, excavators, loader, scraper) 2. Metallurgical machinery (e.g. for steel plant) 3. Heavy machinery equipment (e.g. mining machinery, concrete machinery) 4. Marine machinery equipment (e.g. vessel, port hoisting machine, port oil transfer equipment, onshore and offshore crane) 5. Light machinery equipment (e.g. paper machine, plastic, rubber machine, weave machine) 6. Wind power generator
8. Packing machinery
INSTALLATION OF CZPT SLEWING BEARINGS
Preparation: Make sure that the model is correct and slewing bearing isn’t damaged during transportation. 2. Check the appearance and rotational state of the bearing, such as rotational precision clearance, rotating flexibility, seals position, lubrication grease etc. 3. The installation datum plane and bracket installing plane should be clean, grease, burr, paint and other foreign body should be wiped off.
Installation:
1. The screws in the installing plane should be fit with the mounting holes in the slewing bearing 2. The slewing bearing has a soft zone marked with an “s” on the upper surface, when installing the bearing, it is important to ensure that this area is placed in a non-load or infrequent load zone. 3. When the bearing is placed on the supporting frame work it is important to check the interface between these 2 surfaces. This check should be carried out with the insertion of feel gauges between the 2 surfaces. If a gap should exist then it is recommended to plane/resurface the effective area so as to remove the gap. 4. Install slewing bearing with high strength screws, and choose appropriate strength bolts. All bolts are required to be tightened evenly. The sequence of this tightening process is shown in Pic. Welding of bearing is not allowed, in the event of welding any adjacent parts, heat transfer shall be avoided so as to cause the bearing to become deformed or change the hardness. 5. After installation, the bearing should be rotated to check for smooth operation and any emission of unusual noise. If either of the aforementioned are noted, then the bearing should be adjusted to eliminate them. The teeth of the largest run-out are coated with green paint.

How do Environmental Factors such as Temperature and Exposure to Corrosive Substances Impact Slewing Bearings?
Environmental factors, including temperature variations and exposure to corrosive substances, have a significant impact on the performance and longevity of slewing bearings. Here’s how these factors affect slewing bearings:
Temperature Extremes:
High Temperatures: Excessive heat can lead to premature bearing failure by affecting the lubrication properties, causing thermal expansion, and accelerating wear. Bearings operating at high temperatures require special lubricants and materials that can withstand thermal stresses.
Low Temperatures: Extremely low temperatures can lead to reduced lubricant viscosity, increasing friction and wear. Bearings operating in cold environments might require low-temperature lubricants and materials that maintain their properties in freezing conditions.
Corrosive Substances:
Moisture and Water: Exposure to moisture and water can lead to rust, corrosion, and erosion of bearing components. This is particularly relevant in marine environments or applications exposed to frequent wet conditions.
Chemical Exposure: Corrosive chemicals and aggressive substances can deteriorate bearing materials and lubricants, leading to accelerated wear and potential structural damage.
Dust and Particles: Dust, dirt, and particles can infiltrate the bearing, causing abrasive wear and increasing the risk of damage to the rolling elements and raceways.
Effects on Lubrication:
Temperature extremes and exposure to corrosive substances can compromise the effectiveness of lubrication. High temperatures can degrade lubricants, while corrosive environments can contaminate or dilute lubricants, reducing their protective qualities.
Material Selection:
When designing slewing bearings for specific environments, choosing appropriate materials is crucial. Stainless steels, specialized coatings, and corrosion-resistant materials are often preferred for applications where corrosion is a concern.
Sealing Solutions:
Effective sealing solutions are essential to protect slewing bearings from moisture, chemicals, and contaminants. Proper sealing helps maintain lubrication integrity and prevents external substances from entering the bearing.
Maintenance and Inspection:
Regular maintenance and inspections are critical in environments with temperature fluctuations and corrosive exposure. Prompt removal of contaminants, re-lubrication, and replacement of damaged parts can mitigate the effects of these factors.
Application-Specific Considerations:
Understanding the environmental conditions of the application is essential for selecting the appropriate slewing bearing type, materials, and maintenance practices. Customized solutions might be necessary for extreme environments.
In summary, temperature variations and exposure to corrosive substances can degrade the performance and durability of slewing bearings. Proper material selection, sealing, lubrication, and maintenance practices are vital for ensuring the bearings’ reliability in challenging environmental conditions.
