Stock industrial gearboxes or second-hand industrial gearboxes are actually used gearboxes that are reused in other work fields. The performance and efficiency of these gearboxes depends on their performance, which can affect their durability and lifespan. The high price of new gearboxes, especially those designed by famous brands, has caused some users to buy stock industrial gearboxes. However, the purchase of these gearboxes is accompanied by a series of disadvantages, which we will introduce and review in the rest of this article.
Introducing stock industrial gearbox
A stock industrial gearbox is a gearbox that has already been used for a certain period of time, and for this reason it is also known as a second-hand industrial gearbox. Despite their basic function, these gearboxes have acceptable performance and have their own fans. These gearboxes are offered in different types and models according to their design and structure, the most used of which are used helical gearboxes, used solar gearboxes, used helical gearboxes, etc.
Also, second-hand industrial gearboxes are available in different sizes and capacities that can be used in different working conditions. The type of material used in the construction of these gearboxes and the quality of their components have a great impact on their efficiency and durability, which must be taken into consideration when preparing these devices. However, second-hand gearboxes are not as good as new gearboxes in terms of quality and efficiency, and due to their initial function, they have lower durability and lifespan. In the following, we will introduce the advantages and disadvantages of the stock industrial gearbox, which can be a good guide for you in choosing these devices.

Advantages of buying a second-hand industrial gearbox
Buying a stock gearbox can be associated with advantages, one of the most important of which is the low price of these devices compared to its unused examples. For this reason, these gearboxes can be prepared and purchased with a low budget and used in different fields of work. The second-hand industrial gearbox designed by reputable and popular brands has good efficiency and durability and can be a good choice for many work fields. Also, due to the high price of brand gearboxes, you can also use the stock samples of these devices, which have a low price.
Disadvantages of buying a stock industrial gearbox
Despite its advantages, the second-hand industrial gearbox also has a series of disadvantages, which we will introduce and examine in the following.
The high performance of the device in the disadvantages of buying a stock industrial gearbox
The first disadvantage of the second-hand industrial gearbox is its high performance, which reduces the performance and efficiency of this device in the long run. As you know, every device has a useful life and its parts undergo depreciation after each use, and this gradual depreciation can be associated with a decrease in the performance of the device and a decrease in its lifespan. Gearboxes that have a high performance break down after a few times of use, and fixing this failure in some cases can be associated with high costs for users. Another problem is that buyers do not recognize the exact function of these devices, for which it is necessary to get help from an expert in this field.
The need for repairs in the disadvantages of buying a second-hand industrial gearbox
Another disadvantage of stock industrial gearboxes compared to non-working models of these devices is their constant need for repairs. Since these gearboxes have been working a lot, their parts have gradually depreciated and the possibility of failure of these parts and other parts of the gearbox also increases. The stock industrial gearbox needs constant repairs, and periodic repairs and replacement of its parts will also be accompanied by high costs. Although the buyer pays a small fee for the purchase of this equipment at the beginning, but in the long run, including the maintenance costs, the buyer is required to pay additional and huge costs.

Lack of warranty and warranty on the disadvantages of buying a stock industrial gearbox
The second-hand industrial gearbox does not have any warranty due to its basic function, and this factor is also one of the disadvantages of buying these gearboxes. Since these devices are supplied without warranty, on the one hand, there is a possibility of their failure, and on the other hand, no agency is under the burden of repairing them, which makes the process of repairing them involve high costs.
Uncertainty of quality in the disadvantages of buying a second-hand industrial gearbox
Another disadvantage of buying stock industrial gearboxes is the uncertainty of the quality of these devices. Even if the desired gearbox is from a reputable brand, due to its second-hand condition, there is a possibility of the gearbox being fake and its parts being moved. Another issue in this context is that the sellers of these gearboxes do not mention the level of their operation and depreciation, which will affect the quality and durability of these devices. Also, keeping the problems and failures of these devices hidden from the eyes of the buyers makes them unsure about the quality and efficiency of these devices.

The lack of sufficient power and torque in the disadvantages of buying a stock industrial gearbox
The long-term operation of second-hand industrial gearboxes and the depreciation of their parts and components make these devices not have enough power and torque in different work processes. In other words, the output torque observed in stock gearboxes may not be the same as their output torque in new condition, which can have an adverse effect on the performance of these devices in different working conditions. Accordingly, before using these gearboxes, it is necessary to pay attention to their output torque and its correspondence with the required torque in the system.
Signs of failure of second-hand industrial gearbox
The stock industrial gearbox may have failed due to reasons such as high performance, wear and tear of parts, impact, pressure, etc., which can be recognized by a series of signs and symptoms. Among these symptoms, we can mention the production of noise, overheating of the device, cracks or visible damage, oil leakage, inconsistency of parts, peeling and the effect of rust in them, which we will introduce each of these factors in the following.

Noise production in stock industrial gearbox
One of the signs of failure of second-hand industrial gearboxes is the production of a lot of noise in these devices during operation, which may be caused by the wear of parts on top of each other. The gears, bearings and shafts used in the design of these gearboxes may wear out due to their long-term operation and produce unusual noises when moving together.
Second hand industrial gearbox overheating
Excessive heating of the stock industrial gearbox during operation is a reason for failure and defects in this device, which can be associated with smoke rising from the device, changing the color of the surfaces, or melting its plastic components. Among the reasons for overheating of second-hand gearboxes, we can point out the lack of basic lubrication of the device and the too strong and rigid bearings.
The presence of cracks or visible damage in the stock industrial gearbox
The presence of any visible cracks or damage on the body of the second-hand industrial gearbox and its components is a reason for the failure of this device, which must be checked carefully before buying the gearbox. These cracks and visible damages indicate that the part in question is broken, which needs to be replaced or repaired as soon as possible. The vibration of the device due to its improper operation can be the cause of these cracks and fractures.
