CUMMINS ENGINE HEAD COMPONENTS WITH MAXIMUM STRENGTH AND DURABILITY

Sayani Engineering Sales and Service supply high quality and scientifically designed valve and seat inserts?? You might be wondering regarding such specific design. Do you know that at a vehicular speed of around 50 miles per hour, engine valves open and close about 1200 times per minute in the presence of extreme heat. Thus, it becomes necessary to design the Cummins Engine Head Components in such a way that provides maximum strength and durability.

Cummins Engine Head Components mainly comprise of Valve, Valve Inserts, Valve Guide, Valve Collet Locks and Valve Spring. These components are mainly manufactured using high quality material as follow:-

  • Valve [INLET] is made of Steel [Quality : EN-52 ]
  • Valve [EXHAUST] is made of Steel [Quality : 21-12N]
  • Valve Seat : Stellite Deposit Grade 12
  • Valve Guide : Cast Iron Special Cast Steel
  • Valve Seat : Molybdenum & Deposit Tribaloy - 400 added with iron bus steel

Cummins Engine Head Components
Functions of Engine Head Components:

Valve –
  • It provides gas entry and gas escape from the combustion chamber
  • It transmits combustion heat to lubricant and coolant through the guides and the walls of the cylinder head
Valve Seat Insert –
  • Provides long-life seating area for the valve sealing
  • Allows ease if replacement in high-wear area
Valve Guide –
  • Lubricates and guides the valve stem
  • Control lubrication of stem movement

CUMMINS MAIN BEARING – THE HEART OF AN ENGINE

Do you know that the main bearing is considered as the heart of an Cummins Engine?? They are fitted in the crankshaft to support and protect the rotating parts which in turn allows them to move and rotate freely.

Sayani Engineering sales and service provides Cummins main bearing that is manufactured using high quality bi-metal that holds oil to reduce friction. Besides this various metals are used to make a soft, slippery surface for really heavy shafts.

CUMMINS MAIN BEARING
Cummins main bearing functions majorly to reduce friction most often on a rotating shaft. Besides this the crankshaft of the main engine is supported and connected to the connecting rod via main Bearings whose main function is to transmit the load without any metal to metal contact. It also holds the crankshaft in place and prevents the forces created by the piston, transmitted to the crankshaft by the connecting rods from dislodging it. It instead forces the crank to convert the reciprocating movement into rotation.

We at Sayani Engineering sales and service deals with various modes of Cummins main bearing as follow,
