Precision White-Metal-Lined Journal Bearings for Industrial Rotating Machinery
DEV PRECISION ENGINEERS manufactures and supplies Babbitt (White Metal) Bearings for industrial applications requiring reliable shaft support, suitable running-surface conformability, and effective hydrodynamic lubrication. Depending on the equipment design, bearing construction may include split-shell journal bearings, flanged configurations, and custom bearing assemblies manufactured or refurbished to approved specifications.
White-metal bearings typically use a tin-based or lead-based babbitt lining supported by a suitable steel, cast-iron, bronze, or other specified backing. The lining composition, thickness, bonding process, bearing geometry, and surface finish are selected according to the operating conditions and customer requirements.
Our manufacturing and re-lining capabilities are assessed against the required design, technical drawings, physical samples, and specified material grades.

Key Features & Engineering Advantages
- Conformable Bearing Surface: A suitable white-metal lining can accommodate minor surface irregularities and limited alignment variations within the intended operating conditions.
- Hydrodynamic Lubrication: Appropriate bearing geometry, clearances, and oil-distribution features support the formation of a lubricating film under specified operating conditions.
- Wear and Seizure Considerations: White-metal properties can provide a compatible running surface, but performance depends on the alloy, load, speed, temperature, lubrication, and maintenance conditions.
- Precision Bore Geometry: Controlled bore dimensions, clearances, and alignment help achieve the specified shaft fit and intended lubrication performance.
- Application-Specific Construction: Lining composition, backing material, dimensions, and oil features are selected according to the equipment design and customer specifications.
