rubber coupling for excavator hitachi ex 50

Short Description:

About the rubber coupling:
Rubber coupling is one of the most important parts in an excavator. It’s in stalled on the hydraulic pump. It’s between the hydraulic pump and the engine. The rubber coupling for the excavator is an engine drive coupling. It transmits the power from the excavator coupling to the hydraulic pump. When an engine starts, there is a lot of vibration. These vibrations are generally attenuated by engine damping rubber (also call the rubber engine mount or rubber engine pillow) and couplings. A good shock absorber (the engine mounts) and coupling can greatly extend the working life of an excavator engine and hydraulic pump.
A high-quality coupling will be made of high-quality raw materials. The raw material for making couplings is generally rubber, because rubber has excellent shock absorption.

The material that made the rubber coupling:

There are many classifications of rubber, which can be roughly divided into natural rubber and recycled rubber. The shock absorption effect of these two types of rubber is different. Most of the cheap couplings currently on the market are made of recycled rubber. Recycled rubber has poor shock absorption. If you buy this cheap coupling to install on the excavator, it will damage the performance of the excavator, which will cause the excavator to break down.
The couplings provided by YNF are all made of natural rubber. Although natural rubber is expensive, it has a very good shock absorption effect, and YNF adds anti-aging agent to the raw material, which makes the coupling produced by YNF not only has a good shock absorption effect, but also has a long service life.

About the EX50

About the EX50 model and the EX50 excavator hydraulic pump coupling:
EX50 excavator is a small excavator produced by Hitachi. The EX50U is a small excavator produced by FIAT-HITACHI.
Here are some of the main parameters of the EX50 excavator:

product-1

The excavator uses the engine produced by ISUZU, and the hydraulic pump uses psvd2-21 produced by KAYABA company or pvd-2b-42 produced by NACHI company, and some models may use the PVK-2B-505 hydraulic main pump. (YNF Machinery not only provides couplings, but also hydraulic pumps, hydraulic accessories and other excavator spare parts. If necessary, you can contact our sales staff to learn more.)
