Product Description
Pillow blocks can refer to a variety of bearing styles such as single row ball bearings, double row ball bearings, spherical roller bearings, taper roller bearings, etc. A unit is typically a reference for a 1-piece housing as opposed to a split housing. For simplicity, this article will focus on single row ball bearing units.
“A basic pillow block bearing unit is typically an insert bearing which is based on a sealed deep groove ball bearing and a 1 piece housing.” Joshua Goldman, Applications Engineer for USA says. These units consist of:
*an insert bearing which is based on a sealed single row deep groove ball bearing in the 62 series with a spherical (convex) outside diameter surface and an extended inner ring:
*a one-piece housing made of several different material options which include but are not limited to cast iron, cast stainless steel, and composite. The housing has a correspondingly sphered but concave bore.

How do Slewing Bearings Contribute to the Smooth Rotation of Cranes and other Heavy Machinery?
Slewing bearings play a vital role in ensuring the smooth and efficient rotation of cranes and other heavy machinery that require controlled movement. Their design and functionality are specifically tailored to handle the unique challenges posed by such applications. Here’s how slewing bearings contribute to the smooth rotation of cranes and heavy machinery:
- Load Handling:
Crane operations involve lifting and moving heavy loads. Slewing bearings are designed to carry substantial axial, radial, and moment loads simultaneously. This load-handling capacity allows cranes to lift and transport heavy objects with precision.
- Smooth Rotation:
Slewing bearings provide a smooth interface between the upper structure (superstructure) and the lower structure (substructure) of the machinery. This allows for controlled and precise rotation of the upper structure, enabling cranes to maneuver smoothly during lifting, loading, and unloading operations.
- Efficient Torque Transmission:
During crane rotation, torque generated by the motor is transmitted through the slewing bearing to the upper structure. The bearing’s design ensures efficient torque transmission, minimizing energy losses and facilitating smooth rotation even under heavy loads.
- Low Friction and Wear:
Slewing bearings are engineered to minimize friction and wear. This reduces the energy required for rotation and prevents premature wear that could affect the bearing’s performance and longevity.
- High Stiffness:
Slewing bearings exhibit high stiffness, which contributes to the stability of the machinery during rotation. This stiffness ensures minimal deflection and maintains precise alignment, essential for safe and controlled movement.
- Uniform Load Distribution:
The raceway design of slewing bearings promotes uniform load distribution among rolling elements. This prevents stress concentrations and uneven wear, enhancing the bearing’s durability and contributing to smooth operation.
- Slow and Controlled Movement:
Crane operations often require slow and controlled rotation, especially when positioning heavy loads. Slewing bearings facilitate this type of movement, allowing operators to make precise adjustments.
- Customization for Specific Applications:
Slewing bearings can be customized to match the specific requirements of different crane designs and applications. This customization ensures optimal performance and longevity in various operational scenarios.
In summary, slewing bearings are essential components that enable the smooth and precise rotation of cranes and heavy machinery. Their load-carrying capacity, low friction, high stiffness, and ability to transmit torque efficiently contribute to the reliable and controlled movement required for various lifting and loading operations.
How does Proper Lubrication Impact the Performance and Longevity of Slewing Bearings?
Proper lubrication plays a crucial role in enhancing the performance and extending the longevity of slewing bearings. Here’s how it impacts these aspects:
- Reduced Friction and Wear:
Lubrication forms a protective layer between the rolling elements and raceways, reducing friction and wear. This minimizes surface contact and prevents metal-to-metal contact, leading to less wear and extended bearing life.
- Heat Dissipation:
Lubrication helps dissipate heat generated during operation. Adequate heat management prevents overheating, which can otherwise lead to premature bearing failure and reduced efficiency.
- Corrosion Protection:
Lubricants with anti-corrosion properties form a barrier that protects bearing surfaces from moisture and environmental contaminants. This is crucial in preventing rust and corrosion, especially in challenging operating environments.
- Sealing Effect:
Lubrication can enhance the sealing effect of bearing seals, preventing the ingress of dust, dirt, and other particles. This maintains the integrity of the bearing’s internal components and reduces the risk of contamination-related failures.
- Noise and Vibration Reduction:
Properly lubricated bearings generate less friction and operate more smoothly, resulting in reduced noise and vibration levels. This is particularly important in applications where noise reduction is essential.
- Improved Efficiency:
Effective lubrication minimizes energy losses due to friction, leading to improved overall efficiency of machinery. This is significant in applications that require high performance and energy savings.
- Prevention of Micro-Movements:
Lubrication helps prevent micro-movements between the rolling elements and raceways, reducing wear caused by repeated impacts and vibrations during operation.
- Maintenance Reduction:
Proper lubrication reduces the need for frequent maintenance and replacement of bearings. This not only saves time and resources but also contributes to increased uptime and reduced operational disruptions.
- Longevity:
By reducing wear, preventing corrosion, and managing heat, proper lubrication significantly extends the lifespan of slewing bearings. This, in turn, contributes to improved equipment reliability and reduced lifecycle costs.
In conclusion, proper lubrication is essential for optimizing the performance, efficiency, and durability of slewing bearings. Regular maintenance and adherence to manufacturer-recommended lubrication intervals ensure that the bearings operate smoothly and consistently over their operational life.
What are the Advantages of Using Slewing Bearings in Industrial Applications?
Slewing bearings offer several advantages that make them valuable components in various industrial applications. Some of the key advantages include:
- High Load-Carrying Capacity: Slewing bearings are designed to handle significant axial, radial, and moment loads simultaneously, making them suitable for heavy-duty industrial equipment.
- Space and Weight Savings: Slewing bearings enable compact designs by combining axial and radial bearing functions into a single unit. This helps save space and reduces the overall weight of machinery.
- Smooth Rotational Movement: The design of slewing bearings ensures smooth and precise rotation, contributing to the efficiency and performance of machinery and equipment.
- Minimal Maintenance: Properly lubricated slewing bearings require minimal maintenance due to their robust construction and efficient load distribution.
- Enhanced Durability: Slewing bearings are built to withstand harsh environmental conditions, heavy loads, and repetitive movements, leading to long service life.
- Cost Efficiency: Despite their initial investment, the extended lifespan and low maintenance requirements of slewing bearings result in cost savings over time.
- Customizability: Slewing bearings can be tailored to specific application requirements, including size, load capacity, and sealing options.
- Precise Positioning: Slewing bearings with integral gearing systems allow for accurate positioning, making them ideal for applications that demand controlled movement.
- Versatility: They are used in a wide range of industries, including construction, manufacturing, energy, transportation, and more.
- Reduced Friction and Wear: The rolling-element design of slewing bearings reduces friction and wear, contributing to efficient operation and extended component life.
Overall, the advantages of slewing bearings make them indispensable in industrial applications where reliable and efficient rotational movement is required.
