Clevite 77 TriMetal bearings outperform and outlast all others. It takes three layers to be number one. Steel shell - provides maximum support. Copper/lead - durability and strength for extended life. Babbitt - superior embedability and conformability. Chamfered for large radius fillets. High crush for better seating and retention. It all adds up to superior performance.
