How to choose a slewing bearing?
Slewing bearings are widely used in various types of machinery and equipment. At present, there are many brands of slewing bearings on the market, and the quality is also different. So, how to choose a slewing bearing? What should I pay attention to when buying a slewing bearing? Only in order to select the slewing bearing products of qualified quality, today I will tell you about this issue.
When purchasing slewing ring bearings, there are many issues that need to be paid attention to, such as load, strength of bolts, and whether there are regular bolt holes.
1. Whether the distribution of bearing load is reasonable
Bearings are mounted on a lack of a uniform support surface. A common mistake in the design phase of a support structure is that the slewing ring assumes that the support structure is sufficiently rigid. However, local deformation can change the load, causing the bearing to have different load magnitudes. Failure to take proper steps can easily lead to slewing ring bearing failure.
2. Is the bolt strong enough?
Make sure to choose the right slewing ring bearing product for your installation. This stage is often overlooked, leading to the possibility of system failure. Typically, equipment designers are responsible for determining the correct type of fasteners required for the project. However, fastener suppliers and manufacturers should really get a measure of what a given fastener can withstand. They will be able to assist in the calculation of the bolt loads to confirm the integrity of the fasteners.
3. Is there a unified bolt hole design?
Fasteners need to be placed in more places in larger load areas. Bolt holes can only be used as hazardous support structures in areas where large loads occur and should therefore not be ignored in the overall design of the product. It is important to remember that there is a lot of exercise load, not just the mounting part. Uniform bolt circles can help reduce bending and load distribution in bearings, fasteners, and support structures.
In addition, when we buy a slewing bearing, we should also pay attention to the toughness of this product, because this part is very thin, so many parts look good, but it will be reimbursed after using it in the machine for a long time. When choosing, you can actually buy a few more brands and practice them in practice.
The above are some suggestions on how to purchase slewing bearings. The editor here reminds everyone that when purchasing slewing bearing products, be sure to look at the brand words and labels printed on the slewing bearing. Most of the products produced by the original factory use steel stamping technology, the fonts are very small, and they are embossed before heat treatment, so although the fonts are small, they are deeply concave and very clear. The fonts of counterfeit products are relatively vague. Due to the rough printing technology, the fonts float on the surface, and some can even be easily erased by hand.
