main bearing is a bearing in a piston engine which holds the crankshaft in place and allows it to rotate within the engine block. The number of main bearings...

high-rpm improvements included a flaw-free selected standard block, thicker main bearing caps and crankshaft damper/balancer, larger-diameter rod bolts, a crankshaft...

interconnected main bearing cradles and two bolt main bearing caps. Cylinder heads are made from aluminium. Forged steel crankshafts, and cast iron main bearing support...

the main bearing journals (with the bearing caps forming the other half), although in some engines the crankcase completely surrounds the main bearing journals...

the A711 and A711M blocks (commonly called the 711M block) with square main bearing caps for the Crossflow series, which represented a vast improvement in...

a five-bearing crankshaft design was introduced, the engine prefix became 18GB. Horsepower was rated at 95 net bhp on both five-main-bearing and earlier...

A thrust bearing is a particular type of rotary bearing. Like other bearings they permanently rotate between parts, but they are designed to support a...

A plain bearing, or more commonly sliding contact bearing and slide bearing (in railroading sometimes called a solid bearing, journal bearing, or friction...

A foil bearing, also known as a foil-air bearing, is a type of air bearing. A shaft is supported by a compliant, spring-loaded foil journal lining. Once...

of main bearings is determined based on the overall load factor and the maximum engine speed. Crankshafts in diesel engines often use a main bearing between...

VVT, VTCS, VICS, a stainless steel 4:1 exhaust manifold and a lower main bearing cage for increased block rigidity. Direct-injection is available on the...

to the engine block by main bearings, which allow it to rotate. Bulkheads in the crankcase form a half of every main bearing; the other half is a detachable...

A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts. The design of the...

4.84-inch (123 mm) bore centers, two-bolt main bearing caps, a "side oiling" lubrication system (the main oil gallery located low on the driver's side...

versions of the KA24 used a crankshaft girdle, as opposed to individual main bearing caps. In the Nissan Hardbody and Frontier applications a crank girdle...

A jewel bearing is a plain bearing in which a metal spindle turns in a jewel-lined pivot hole. The hole is typically shaped like a torus and is slightly...

either four main bearings (i.e., a bearing in between each pair of crankpins and one at each end) or seven main bearings (i.e., a bearing between every...

DB4 series injection pump can be found on some 6.5L marine engines. Main Bearing Web Crack: In both 6.2L and 6.5L engines, this is reportedly fixed with...

cross-bolted bearing is a bearing, usually a crankshaft main bearing of a piston engine, reinforced with additional transverse bolts. Most bearing caps are...

cylinders that share a pair of main bearings have a smaller pitch than between #2 & 3 and #4 & 5 that "bridge" a main bearing. Since the start-up expense...
