ZYS slewing bearings can be divided into the following types according to their structures as single row 4 point contact ball slewing bearing, single row cross roller slewing bearing, double row different ball diameter slewing bearing, 3 row cylindrical roller slewing bearing and roller/ball combination slewing bearing. These types of bearings can be further divided into bearings without gears, bearings with external gears and bearings with internal gears.
Slewing bearing type
Single row 4 point contact ball slewing bearing
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 bearing
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 bearing
This kind of bearings can support high static loads with simple structures. They are mainly used in situations with variational load position and direction and continuously rotating. Main applications of this kind of bearings are deck hoisting, mining and material handling etc.
Three row cylindrical roller slewing bearing
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. Usually they are large diameter slewing bearings. Applications of this kind of bearings are mining and materials handling etc.
Materials of slewing bearing
1. Material of slewing ring: 42CrMo is generally used for CZPT slewing ring with surface quenching treatment of the raceway. Other kinds of surface quenched steel can also be used according to customer specification and operating conditions.
2. Material of rolling element: The material of rolling elements in CZPT bearing is GCr15 or GCr15SiMn steel.
3. Material of cage: Various types of cage are used in CZPT slewing bearing, which can be divided into integrated cage, segmented cage, spacer and etc. 20 steel or ZL102 cast aluminum alloy is used for integrated cage and segmented cage. For spacer,the material is polyamide 1571 resin, ZL102 aluminum bronze, QA110-3-1.5 aluminum bronze or GRPA66-25 nylon. 4. Material of sealing ring: The sealing ring is made of NBR.

What Role do Seals and Enclosures Play in Protecting Slewing Bearings from Contaminants?
Seals and enclosures play a crucial role in safeguarding slewing bearings from contaminants, moisture, and other external factors that can lead to premature wear and damage. Here’s how seals and enclosures contribute to the protection of slewing bearings:
- Contaminant Exclusion:
Seals and enclosures create a physical barrier that prevents contaminants like dust, dirt, sand, and particles from entering the bearing’s internal components. This exclusion minimizes abrasive wear and preserves the integrity of the rolling elements and raceways.
- Moisture and Corrosion Prevention:
Seals and enclosures provide a shield against moisture and water ingress, crucial in preventing corrosion and rust formation on bearing surfaces. Corrosion-resistant seals are particularly valuable in marine and humid environments.
- Chemical and Chemical Vapor Resistance:
Specialized seals and enclosures can offer resistance to chemicals, acids, and corrosive substances that might be present in the operating environment. This protection prevents chemical damage to the bearing’s components.
- Lubrication Retention:
Seals and enclosures help retain the lubricant within the bearing, preventing it from leaking out and ensuring consistent lubrication for smooth operation. This is essential for reducing friction and wear.
- Prevention of Solid Particle Contamination:
Seals and enclosures block solid particles from entering the bearing chamber, reducing the risk of particle-induced wear, surface damage, and premature failure.
- Temperature Regulation:
Some seals and enclosures offer thermal insulation, which helps regulate the operating temperature of the bearing. This can be crucial in applications with extreme temperature variations.
- Enhanced Longevity:
By protecting the bearing from contaminants and adverse environmental conditions, seals and enclosures contribute to the extension of the bearing’s operational life, reducing the need for frequent replacements.
- Sealing Types:
Seals can come in various types, including lip seals, labyrinth seals, and specialized designs. The choice of seal depends on the application’s requirements and the level of protection needed.
- Proper Installation and Maintenance:
Proper installation and regular inspection of seals and enclosures are essential to ensure their effectiveness. Damaged or worn seals should be promptly replaced to maintain protection.
In summary, seals and enclosures serve as a critical defense mechanism for slewing bearings against contaminants, moisture, and harmful substances. They contribute to the bearing’s reliability, performance, and overall longevity in various operating environments.
