How to Save Money When Buying Industrial Combined Journal Bearings

As with any commodity, there are always benefits when buying in bulk and the same applies when buying fasteners . The first most obvious benefit is, of course, the cost saving. When you buy in bulk, you benefit from the economy of scale, making the cost per item far cheaper than if you were buying in smaller quantities. The second benefit is that buying in bulk means you can do fewer shopping trips, saving you the time and inconvenience of constantly having to replenish your fastener stock hold.

These benefits create an obvious allure to buying in bulk. Who wouldn’t want to save time and money? Unfortunately, many people don’t always consider the risks that often come with it, choosing to ignore the more sensible option in the drive to save money. Being aware of these common errors might save you from making that mistake, so keep the following points in mind when you’re looking to buy fasteners in bulk.

Assess Your Needs

One of the biggest mistakes people make when buying fasteners in bulk is that they assume they’ll use them all up. If you haven’t done a proper assessment of what the application truly requires, you’re going to end up discarding most of your purchase or leaving the balance to rust in storage. An assessment is even more important if the application requires a variety of different fasteners. Some fasteners are far more expensive than others so it can be tricky to determine what is worth bulk buying and what not. In most cases, hiring a professional service to consult on your needs is the best way to manage your inventory and many of these services offer a ‘buy-back’ on unused items, saving you the cost and hassle that comes with over-purchasing.

Certified Testing

Many people can get carried away when buying in bulk but it’s important to remember that you’ll always be paying more up front, which is an obvious risk. If you must invest in a large number of fasteners, however, then it would be wise to ensure that the fasteners you purchase are of the correct design and quality, according to your and the manufacturer’s expectations. Asking for test samples allows you to test the products yourself but most industrial fasteners are covered by specific industry standards and you can request certification to prove the fastener’s material properties and tolerances.

Do Your Homework

Another mistake people make is not comparing the sale price of fasteners to the bulk prices, simply assuming that the bulk price is cheaper. Many vendors are simply not in a position to lower their prices, even on larger quantities, so it’s vital that you do your research and choose a reputable vendor that’s going to meet your needs.

Installing the right bearing is essential for getting the most out of your equipment. When the wrong bearing is used, it can lower efficiency, require more maintenance, and, in the worst cases, cause equipment to stop working and cost a lot of money to fix. The fact that there are different types of bearings doesn't make your choice any more straightforward.

It can be hard to choose suitable industrial bearings. During use, industrial bearings and power transmission equipment create a complex matrix of forces, such as speeds, temperatures, and pressures, that often interact in nonlinear ways. 

Here are seven of the top factors worth thinking about when choosing a suitable journal bearing 

1. Load

There are several ways to measure bearing load. Radial load is put on the shaft at the right angle. Axial load is a way to measure forces that act in the same direction as the shaft. Radial and axial loads can work together to make a moment or combined load in a system. A bearing must be able to handle all three types of loads over their expected range.

2. Tolerance

ISO and JIS standards determine how well cylindrical roller bearings with spacers fit and how well they turn. It is best to use paths with an accuracy level of 5 or higher in machines that need to work with high precision and speed. Machines that need to run with high accuracy can use deep groove ball bearings, radial thrust ball bearings, or cylindrical roller bearings.

3. Speed

Every bearing is made to work well at a specific range of speeds. A system that moves fast will need different bearings than one that moves at a slow rate. High-speed bearings must keep working safely even if they are slightly out of alignment, which can have a much more significant effect when turning quickly.

4. Temperature

To get the most out of a system that rotates, you need to know how temperature changes affect its parts. Journal bearing can add a lot of heat to a system, and how they react to heat from other factors is also very important. The bearing's lubrication must be set to the temperatures at which the bearing will be used.

5. Rotation Accuracy

Most journals bearing 0-level tolerance bearings are enough to meet the needs of the host. However, when the accuracy of the shaft's rotation is critical, such as in machine tool spindles, precision machinery, and instruments, higher tolerance deep groove ball bearings should be used.

6. Rigidity

This amount of change is minimal and can be ignored most of the time. However, in some machines, like machine tool spindle systems, the static and dynamic stiffness of the bearing has a significant effect on how the system works.

7. Friction torque

Ball bearings have less resistance to friction than roller bearings. The friction resistance is low when a pure radial load is put on a radial contact bearing. Friction resistance is common when a pure axial load is placed on an axial contact bearing. 

Choosing journal bearing is not finished until the long-term industrial maintenance services are examined.

Selecting an approach can be like selecting any other piece of hardware: you have to find a balance between price and performance. A more vital bearing may cost more but will need less maintenance and replacement. Other things to think about are how easy it is to lubricate and check the directions.
