Precision Steel-Backed Bi-Metal Bearings Aluminum-Tin AT & Copper-Lead CL for Engines & Industrial Applications
DEV PRECISION ENGINEERS manufactures and exports high-precision bi-metal bearings engineered for reliable load support, wear resistance, and thermal performance across demanding industrial and powertrain applications. By bonding a steel backing with an application-specific aluminum-tin (Al-Sn) or copper-lead (Cu-Pb) bearing alloy, our two-layer bearing solutions are designed to deliver structural strength, fatigue resistance, and dependable operating performance in rotating and reciprocating machinery.
Our manufacturing capabilities support plain bearing shells, flanged bearings, main journal bearings, connecting-rod bearings, and other custom-engineered configurations. From OEM production and aftermarket replacements to specialised low-volume manufacturing projects, we supply bi-metal bearing components according to customer drawings, reference samples, dimensional requirements, and material specifications.

Key Features & Advantages
- Structural Strength & Dimensional Stability: The steel backing provides structural support and helps maintain the required bearing geometry and housing fit when manufactured to the specified tolerances.
- Thermal Performance: Aluminum-tin and copper-lead bearing alloys offer different thermal and mechanical characteristics. Appropriate alloy selection and effective lubrication help manage heat at the shaft-bearing interface.
- Wear Resistance & Conformability: Depending on the selected alloy and surface construction, the bearing layer can provide suitable wear resistance and accommodate minor misalignment or surface irregularities within the intended operating limits.
- Embeddability & Shaft Protection: Where supported by the selected alloy and any overlay, bearing-surface properties can help accommodate small contaminants and reduce the risk of damage to the mating shaft or journal.
- Application-Specific Material Selection: Alloy composition and bearing construction can be selected according to load, operating speed, temperature, lubrication, and equipment requirements.
- Precision Fitment: Controlled dimensions, wall thickness, and bearing geometry support correct installation, specified clearances, and the intended lubrication conditions.
