In the world of heavy machinery and industrial applications, the efficiency and reliability of rotating equipment are critically dependent on the quality of the bearings they use. Bearings are not just mechanical components — they are the foundation of smooth, frictionless movement in a wide array of equipment, from turbines to compressors, gearboxes to rolling mills. Among all types of bearings, white metal bearings and Babbitt metal bearings hold a distinct place due to their exceptional durability, load-bearing capacity, and adaptability in high-load and high-speed environments.
If you’re looking to buy white metal bearings or Babbitt metal bearings for industrial use, you’re making a strategic investment in the long-term performance of your machinery. These bearings are designed to operate under demanding conditions while minimizing wear, reducing maintenance downtime, and maximizing machine life.
What Are White Metal Bearings and Babbitt Metal Bearings?
White metal bearings and Babbitt metal bearings are essentially the same category of component — the term “Babbitt” refers to the white metal alloy originally invented by Isaac Babbitt in the 19th century. This alloy is composed of tin or lead mixed with copper and antimony, giving it the perfect blend of softness, lubricity, and conformability. These characteristics make Babbitt alloys ideal for applications requiring hydrodynamic lubrication.
In white metal bearings, the inner surface of the bearing housing is lined with a Babbitt metal layer, which provides excellent resistance to friction and wear. These bearings are used in a wide variety of industrial machines due to their ability to conform to shaft imperfections, embed small contaminants, and allow for better heat dissipation.
Why Use White Metal or Babbitt Bearings in Industry?
Heavy-duty industrial machinery demands components that are not only strong but also capable of withstanding continuous stress, vibration, and heat. White metal bearings meet all these criteria, offering several critical advantages:
Hydrodynamic Lubrication Support: Designed to create a lubricating film between the shaft and bearing surface, reducing metal-to-metal contact.
High Load-Carrying Capacity: Suitable for radial and axial load support in turbines, mills, and generators.
Thermal Conductivity: Quickly dissipates heat generated during operation, reducing thermal stress on machinery.
Embedded Contaminant Tolerance: Traps small particles within the Babbitt lining, protecting the shaft from scoring.
Self-Lubricating Properties: Babbitt metal supports smooth, quiet operation with minimal maintenance.
These attributes make them a go-to solution for long-term, cost-effective industrial machinery performance.
Common Industrial Applications
White metal bearings are found in a broad spectrum of industries, including:
Power Plants: For turbines, pumps, and generators
Cement Plants: Used in rotary kilns, mills, and fans
Steel Plants: For rolling mills, blowers, and drives
Marine Industry: Engine bearings and propulsion systems
Mining & Minerals: Ball mills, crushers, and gearboxes
Pulp & Paper Mills: Calendar rolls, dryers, and motors
Sugar Plants: Cane mills, gearboxes, and turbines
In every case, Babbitt-lined bearings deliver consistent reliability, reduced friction, and optimal machine performance even under continuous use.
Types of White Metal Bearings You Can Buy
When sourcing bearings for industrial use, it’s essential to choose the right configuration for your equipment. At Siddhi Auto Spares, we offer the following types of white metal and Babbitt bearings:
1. Journal Bearings
Used to support radial loads in rotating equipment like turbines, compressors, and motors. These bearings operate under a full oil film and are available in both solid and split shell types.
2. Thrust Bearings
Designed to carry axial loads, these bearings are used in vertical shaft equipment such as vertical turbines and pumps. They can be made as single-pad or multi-pad configurations.
3. Tilting Pad Bearings
Ideal for high-speed, high-load machinery, these consist of multiple individual pads that tilt to accommodate dynamic shaft movement, providing exceptional stability and load distribution.
4. Pedestal Bearings
Used in large motor assemblies and fans. They are mounted in housing units that support easy maintenance and shaft alignment.
5. Trunnion Bearings
Common in cement kilns and ball mills, trunnion bearings support the large rotating drums and maintain structural integrity under extreme stress.
6. Split Bearings
These bearings are horizontally split, allowing for easy installation and maintenance in hard-to-reach locations.
7. Babbitt Bushings and Sleeves
Small custom-engineered solutions ideal for pumps, gearboxes, and marine equipment.
Custom Manufacturing & Rebabbitting Services
Every industry has unique operational demands, which is why customization plays a critical role. At Siddhi Auto Spares, we offer custom-manufactured white metal bearings based on:
Customer drawings or OEM specs
Shaft size and housing tolerances
Load and speed requirements
Application environment (temperature, lubrication method, etc.)
Additionally, we specialize in rebabbitting services — the process of restoring used bearings by stripping the old Babbitt layer, recasting a fresh layer using centrifugal or gravity casting, and finishing the surface to precise tolerances. Rebabbitting is a highly cost-effective and sustainable way to extend the lifespan of your equipment without investing in new parts.
What to Consider Before Buying White Metal Bearings
Before you purchase Babbitt metal bearings for your operations, here are key factors to evaluate:
Material Composition: Tin-based Babbitt is better for high-speed, high-load environments, while lead-based Babbitt is suitable for general applications.
Operating Temperature: Ensure the alloy can handle the heat generated during operation.
Lubrication Compatibility: Hydrodynamic lubrication is essential for optimal performance.
Shaft Alignment: Misalignment can reduce bearing life and lead to failure.
Load Conditions: Understand radial and axial load requirements to choose the correct bearing type.
