Main Bearing BIG 750‑11240 is a precision engine component designed to support the crankshaft and allow it to rotate smoothly under heavy load. It reduces friction between moving parts, ensuring reliable performance and longer engine life in diesel engines and industrial power units. Main bearings are critical to engine durability and proper crankshaft alignment.
Where It Is Used
The 750‑11240 main bearing is commonly used in:
-
Lister‑Petter diesel engines such as LPW, LPWS and LPA series, especially at the gear end of the crankshaft.
-
Industrial generator engines and heavy machinery powered by compatible diesel blocks
-
Engines requiring crankshaft support and low‑friction rotation under high loads
This part fits standard size crankshaft journals and may be used in engine rebuilds or overhauls where the bearing surface needs replacement.
Key Functions
-
Supports the crankshaft inside the engine block, keeping it aligned and stable
-
Reduces friction and wear between the crankshaft journal and engine block
-
Ensures smooth engine rotation even under heavy mechanical load
-
Made from high‑strength, wear‑resistant alloys that withstand high temperatures and pressures
-
Critical for preventing premature engine failure and extending service life
Main bearings like the 750‑11240 are essential for engine performance, especially in continuous‑use applications such as generators, industrial compressors, agricultural engines, and construction equipment.
