Tri Metallic Bush

TriMetal engine Bearings & Bushings have been the industry standard since the first patent on the cast, copper, lead composition decades ago. We manufacture & Export Plain, Thinwalled, Cut Type as well as Flange bushings in various metals & composition. We manufacture bushings for Railways (Locomotives), Compressors, Turbines, High Pressure Pumps, homogenizer, other rotating & reciprocating machinery. We manufacture these bushings Through Centrifugal Casting which enables us to manufacture Bushings in Large (Bulk) quantity as well as in small quantity.

Seizure Resistance – TriMetal Bearings & Bushings have as much as 20-40% better seizure resistance than competitors’ engine bearings.

Load Capacity – TriMetal Bearings & Bushings can withstand over 40-60% higher loads for extended periods compared to competitor bearings.

Embedability & Conformability – The overlay on a TriMetal™ bearing offers a superior surface for forgiveness, offering additional protection that can be extremely beneficial in an engine that is poorly maintained.

Durability – TriMetal Bearings & Bushings not only exceed light vehicle OE durability requirements, they also exceed heavy vehicle OE durability requirements.

Bearing design features a steel backing for support, a cast-copper lead alloy center for strength and a overlay of casted white metal/Lead for slipperiness, conformability and embedability. The intermediate cast-copper lead layer creates and interlocked columnar structure capable of withstanding much heavier pulsating loads than any other bearing design. They are more resistant to corrosion and out-perform traditional Bearings & Bushings by 10-20 % or more.

TIN Based Babbitt OVER LAY (WHITE METAL)

• Tin based overlays contain copper (8-12%) as a hardening component.
• The alloys are developed to replace toxic lead based overlays.
• Tin based overlays possess excellent corrosion resistance and cavitation resistance. Overlay multilayer system of Sn alloy deposited on the bi-layer the overlay thickness due to varying content of copper (soft top layer and hard bottom layer of the overlay). Such multilayer Bearings & Bushings are capable to withstand alternating loads up to 11600-13000 psi (80-90 MPa).
• Hardness of tin-copper overlays is 20-30 HV.
