A crankshaft contains two or more centrally-located coaxial cylindrical ("main") journals and one or more offset cylindrical crankpin ("rod") journals. The two-plane V8 crankshaft pictured in Figure 1 has five main journals and four rod journals, each spaced 90 from its neigbors.

The crankshaft main journals rotate in a set of supporting bearings ("main bearings"), causing the offset rod journals to rotate in a circular path around the main journal centers, the diameter of which is twice the offset of the rod journals. The diameter of that path is the engine "stroke": the distance the piston moves up and down in its cylinder. The big ends of the connecting rods ("conrods") contain bearings ("rod bearings") which ride on the (offset) rod journals.

Valve blocks are specially designed and manufactured according to the application of each customer. They are manufactured with an advanced engineering approach meeting the circuit logic and functionality, performance, safety and installation expectations.

The engine block is the linchpin of vehicles that run on internal combustion, providing the powerhouse for the vehicle. It is called a "block" because it is usually a solid cast car part, housing the cylinders and their components inside a cooled and lubricated crankcase.

slewing bearings are machine elements which absorb all axial and radial forces and the resulting tilting moments in a single self-retaining and ready-to-install unit. Their low profile and an excellent weightperformance ratio, open center, and the possibility of an integrated gearing make Rotek slewing bearings ideal structural components.

Without baffles, most impellers styles impose a tangential flow pattern. With baffles, most impellers show their true flow characteristics. Impellers are sorted here by the flow patterns they were intended to create, radial flow impellers and axial flow impellers.

Engine block or cylinder block - is consider the " backbone" of the engine to which all other parts are bolted or attached. Some Car manufacturers mass produced engine blocks but some made it one at a time for special cases.

The gas and steam turbine rotor manufacturing process employs our unique technology. The forged rotor sections are machined, inspected and then automatically welded together. This technique is unique to our manufacturing process. It ensures high integrity and maintenance-free rotors, but most important reduces weight by including defined cavities. Thanks to the reduced weight, the rotors reach their operating temperature faster and are less exposed to material stresses when cooling down. Overall, this allows a more flexible plant operation according to the necessary power load to be produced.
After ultrasonic testing and alignment, the rotor is mechanically machined in two stages: first the rotor is turned to measure on a large turning lathe, and then it is drilled and milled. After seals and blading are mounted, the finished rotor is balanced and undergoes an over-speed test.

A magneto is an electrical generator that uses permanent magnets to produce alternating current. Unlike a dynamo, there is no commutator and so they cannot produce direct current. They are categorised as a form of alternator, although they are usually regarded as distinct from most other alternators, which use field coils rather than permanent magnets.
