Bearing FAQs: Find Answers to Commonly Asked Questions about Bearings
January 22, 2023We have included a large number of questions that are asked rather frequently (FAQs) concerning bearings (such as ball bearings, roller bearings, plain bearings, and linear bearings), as well as goods that are linked to bearings (and bearing services too). Be brought to an amazingly concise, straightforward, and correct answer by reading through.
Is it Possible to Refurbish Bearings?
Yes, but it depends. To attempt to rehabilitate a bearing product is, in most cases and for most tiny bearings, an economically inefficient endeavour. On the other hand, there is the possibility of economic advantages for bearings with six inches and greater bore sizes and larger. Specifically, suitable for refurbishment bearings include slewing rings, cylindrical roller bearings, and spherical roller bearings. However, in addition to the amount of wear accumulated, numerous other aspects are involved in this costly choice. Other factors include maintenance cycles, lubrication, MTBF, environmental concerns, and more.
If you have a particular query regarding the refurbishment of bearings, you should speak with our professionals here at Global Bearings immediately.
How Do I Determine Which Bearing Is Best Suited For My Application?
When choosing the specs for your design, we strongly recommend you get in touch with one of our bearing application engineers for assistance. Global Bearings provides knowledgeable sales and expert personnel to assist in product design and selection, aiming to increase performance and ensure your company’s success.
How Long Are Bearings Designed to Last?
Lubrication is the essential aspect that plays a role in determining the shelf life of a bearing that has been “properly kept.” There is a finite lifespan for greases and oils (expiration dates), discussed more in our “Life of Bearings Explained” blog. In any other case, provided that the bearing is maintained properly (usually in the packaging that it came in when it was manufactured), possible contamination and oxidation impacts will be negligible. They will not materially affect the bearing’s shelf life.
Will Corrosion Be Prevented by Using a Bearing Made of Stainless Steel?
Although stainless steel is described as “corrosion-resistant,” it is not rust-proof and will corrode over time in corrosive conditions. Stainless steel, however, will erode at a considerably more glacial pace compared to chrome alloy steel. But things aren’t quite as straightforward as that. There are several sorts of stainless steel, each of which has unique features regarding its corrosion resistance. For instance, the special steel known as SV30 has a far higher resistance to corrosion than the stainless steel known as 440C.
How Exactly Does One Go About Measuring the Bearing Material’s Hardness?
Rockwell, Brinell, Vickers, and Shore are some of the common scales used to measure a material’s hardness. The Rockwell scale is often the one that is utilised for bearings. However, even within the Rockwell Hardness Test, several distinct scales are used to indicate the hardness level of various types of materials. Because bearings are often constructed from very hard materials, the Rockwell “C Scale” is the method of choice for determining the relative degree of hardness of bearing materials.
