This thread is a question about mounting unmatched A/C bearing in a homemade housing, using Belleville washers to achive a so called "Constant Pressure Preload".I know that this is just another thread in the line many, but I couldn'd really find alot of posts where this subject is discussed in detail.In the early stage of building my new router, I decided to make my own fixed bearings units, because they were awfullly expensive. How hard could it be just to mount two bearings in a housing? - Now I have learned whyThe nuts and screws, which are the heart to accuracy of the system, won't be to any good, without the use of proper bearings. I just mean, that the quality of the bearing setup, should equal the quality of nut/screw. My learning curve regarding A/C bearings have been quite vertical these days.A week ago, I bought some NSK/IBU B A/C bearings from Ebay, to use with my 16mm ball screws. As I was digging into the subject of fixed bearings, I got pretty frustrated. I've found out that it is impossible for me to make a decent DB or DF preload configuration. As the more "educated" person can see, there is not given a lot of details about the bearings, with good reason. They are of course unmatched, leading to the fact that it is difficult to preload them properly in either a DB or DF configuration.I've wrote NC Cams to give his opinion on just setting some preload on the bearings with a torque wrench, but he told me to buy matched pairs and fabricate exact spacers, otherwise I could easily ruin the bearings, because preloading with a torque wrench was too unpredictable.Problem is, that I don't think it's possible for me to make those spacers precise enough. Another problem is the money required to buy those matched bearings.-------------------------------------------Well, here is the deal (and please correct me if I'm wrong)When reading on the NSK homepage, I saw this Constant Preload configuration and this seems to be my only way out. As you can see on my drawings, the bearings are seperated with two Belleville springs in series. Combusting the washers with 75% of their span, gives a preload of N. The preload is forced onto the two bearings, given that they will each be dealing with 585N.The force from the ball screw is around 200-300N, so the preload should be heavy enough to withstand that force in either direction, or?The nominal heavy preload for that particularly bearing is 78.5N, but I assume that 585N will not be any deal to the bearings? Does that EXTRA HEAVY preload affect the bearings in a negative way? Important is, that the bearings are always preloaded, I guess. This should just be a way to have some kind of control over the situation.Long thread, I know. Hopefully it can be useful to other members.CNCDevil

Disc springs, also known as disc springs or Belleville springs, are a type of engineering springs that consist of concentric discs. They are characterized by their high spring force and their flat design. Disc springs are often used in applications where high axial loads are required in limited installation space. In this article we will go into more detail about choosing a disc spring manufacturer.
Due to their conical shape, disc springs act like coil springs. When an axial load is applied to the disc spring, the discs compress and store energy. This energy is released as the load decreases, causing the disc spring to regain its original shape.
Disc springs are used in a variety of applications including:
Automotive industry: Disc springs are used in clutches, shock absorbers and brake systems.
Mechanical engineering: Disc springs are used in gearboxes, clutches, valves and bearings.
Aerospace: Disc springs are used in aircraft and rockets for various applications.
Electronics industry: Disc springs are used for electrical contacting in switches and connectors.
Medical technology: Disc springs are used in medical devices for precision applications.
Selecting a reliable and qualified disc spring manufacturer is crucial to the success of your project. A good manufacturer not only offers high-quality products, but also excellent customer service and technical support. Working with an experienced manufacturer ensures timely delivery of high quality disc springs that meet the needs of your application.
When choosing a disc spring manufacturer, you should consider the following criteria:
Experience and expertise of the manufacturer in the production of disc springs.
Certifications and standards that the manufacturer meets.
Manufacturer production capacity and flexibility to meet your needs.
Experience reports and references from other customers.
Delivery times and shipping options from the manufacturer.
Quality assurance processes and guarantees offered by the manufacturer.
Customer service and technical support from the manufacturer.
By carefully assessing these criteria, you can choose the best disc spring manufacturer for your company.
Finding the right disc spring manufacturer requires thorough research and evaluation. Here are some steps to help you choose:
Conduct extensive online research to find disc spring manufacturers. Check their websites to learn more about their services, specializations and credentials. Read customer reviews and testimonials to get an idea of &#;&#;the manufacturer&#;s quality and reliability. Also consider recommendations from business partners and industry experts.
After identifying potential manufacturers, you can make requests for quotes and samples. Most manufacturers offer free quotes and samples to help you evaluate their products and services. Be sure to provide clear specifications and requirements so that the manufacturer can provide an accurate quote.
Another way to get to know potential disc spring manufacturers is to attend trade fairs and exhibitions in the industry. There you have the opportunity to meet various manufacturers in person, see their products and ask questions. Trade fairs and exhibitions offer a great opportunity to network with manufacturers and establish direct contacts.
Combining these steps will help you find the right manufacturer that meets your needs.
Quality assurance is a crucial factor when selecting a disc spring manufacturer. Here are some aspects of quality assurance to consider:
Check whether the manufacturer meets the required certifications and standards. This can include ISO certifications, industry-specific standards or customer-specific requirements. Certifications are an indicator of compliance with high quality standards and processes.
Learn more about the manufacturer&#;s quality control processes. This may include inspections, testing and verification to ensure that the disc springs meet the specified requirements. A good manufacturer will implement robust quality control processes to ensure the consistency and reliability of their products.
Ask about the manufacturer&#;s warranties and return policies. A solid warranty policy gives you peace of mind that the manufacturer stands behind its products. Return policy allows you to return faulty or inadequate disc springs and receive a refund or replacement.
Quality assurance plays a crucial role in choosing a reliable disc spring manufacturer.
Good customer service is a crucial factor when choosing a disc spring manufacturer. Here are some aspects of customer service to consider:
Note how quickly the manufacturer responds to your inquiries and how well they communicate. A responsive manufacturer will help you clarify questions and resolve concerns. Open and clear communication is important to ensure your needs are met.
