Factory directly Drive Shaft Flexible Coupling - Excavator coupling 778322 16as – YNF

Product OverviewCoupling for Cat 325C

The numbers 2019608 3633643 778322 are the serial number. When we confirm this series coupling, we are only confirm the numbers 2019608 3633643 778322 but also the size number. There are many different sizes in this series, from size 2 to size 400 (provided by the YNF coupling manufacturer).

In this listing, it’s about the size 16 CF-A coupling.

There are two kinds of holes for this size of coupling. They are the step holes and the straight holes.

Here’s the illustration how the step holes (AS coupling) and the straight holes (A coupling).

As you can see, the straight holes are the through holes while the step holes are half-through holes with step inside.

Here’s the dimensions of the excavator coupling 778322 16as:

Product Description

The excavator coupling 778322 16as is used on many different excavator models. It’s installed between the hydraulic pump and the engine. The CF-A series flexible rubber couplings produced by YNF Machiney are made of natrual rubber. Mostly of the rubber couplings in the market are made of the recycled rubber.
Our excavator coupling 778322 16as is more flexible, and because we have add the anti-aged agent into the raw material, the working life of the excavator coupling 778322 16as provided by YNF is much longer than other suppliers’.

Rubber Couplings are used extensively in many industrial applications, especially with engines. Mainly used for their torsionally soft properties and damping effect on troublesome vibrations. There are some drawbacks of rubber couplings: Rubber materials used in these couplings are subject to degradation over time.

Application:

Construction machinery/Agricultural machinery/Ships/Generators/Special-purpose vehicles/Machine tools/Inspection equipement/Wind power generators.

Functions

Power is transmitted by highly elastic rubber.Rubber is excellent at absorbing vibration and shock and also reduces machinery noise. The rubber components of the elastic body are constructed of polygonal rubber with aluminum inserts inserted into their tips. Each is formed by rigid vulcanizing adhesion. These rubber bodies are coupled by bolts in the radial and axial directions of the cylindrical hub and flange hub so that power is transmitted via the rubber body. The bolt coupling in the radial direction is particular has a pre-compressed construction and enables power transmission that is excellent in flexibility and absorption of vibration and shock.
