The hidden side of needle roller bearings.

Image
  There are many types of bearings, the most common are ball bearings, or tapered roller bearings, cylindrical or spherical roller bearings. Their design meets certain technical requirements to adapt to the specific application. Less known is the needle roller bearing , but it is indispensable in certain applications where high demands are made on reliability and durability. Discover the hidden side of needle bearings that fit into many mechanisms. What is so special about them? The rolling elements used are shaped like needles, hence the name. These steel needles with a round or flat tip have a diameter of no more than 5 mm, and their length must be at least 3 times greater than their diameter. The bearing supports very high loads thanks to the contact the area developed by the needles, which are mounted in a cage made of steel or molded polyamide. It allows for extremely compact assemblies and is the bearing of choice when looking for a good compromise between performance...

Relationship between ball bearings and vehicles

Image
  Bearing products, especially ball bearings , are always said to have a close relationship with automobiles. In fact, this is very true. Moreover, they can be used to solve some problems that other parts cannot meet the requirements. For example, when the surface on which the vehicle is driving is either slippery or extremely rough, some methods such as steering, accelerating, and braking are not enough to control the vehicle. In such situations, this kind of bearing product is needed. Ball bearings are a widely used type of bearing product. They mainly support radial and moderate axial loads. They also have a low coefficient of friction, high limiting speed, wide size range, and various structures. They can typically be used in electric motors, automotive applications, home appliances, and industrial equipment. They can be further divided into different categories, such as miniature ball bearings , angular contact ball bearings , and flanged ball bearings, etc. All of them ha...

Fits for Radial Ball Bearings

Image
  Selecting the right fits for the shaft and housing are critical to optimizing the performance and life of a radial ball bearing . A bearing can only perform to its full potential if it is properly fitted to the shaft and into the housing. Improper fits can lead to undesirable operating conditions and premature failure. Following are some of the general considerations bearing users should take into account: Direction, type, and magnitude of the load. An equivalent radial load is calculated from the actual axial and radial loads applied. In general, tighter fits are required as the load increases. In addition, rings subjected to circumferential loading should have tight fits. For rings that are only subjected to point loads, a loose fit can be used. Rotation of the inner or outer ring Typically, the rotating ring requires an interference fit, while the non-rotating ring should have a slightly loose fit. The specified size and type of bearing Thin-walled and miniature ...

Balls and ball bearings for medical applications

Image
Medical devices use specialized precision balls, pins, and assemblies in applications ranging from intravenous administration to surgical tools. Materials used for medical specialty balls include glass and plastic, as well as 302, 304 and 316 stainless steel balls, pins, and assemblies. It is of utmost importance that engineers pay close attention to the ball and pin cleaning requirements, as the medical industry demands strict cleanliness standards. For example, ultrasonic cleaning capabilities, as well as a clean room, are necessary to meet the most stringent requirements for specialty medical balls. Visit also: Ball Bearings Angular Contact Series The following materials are commonly used for ball applications in the medical industry: Materials Common materials used for balls in medical devices include. - Stainless steel - Polyamide (PA) - Polycarbonate (PC) - Polyethylene (PE) - Polypropylene (PP) - Borosilicate glass Their applications and advantages are dis...

Deep Groove Ball Bearings Types, Design and Applications

Image
  Deep groove ball bearing is a common type of bearing and is used in many industries, from heavy machinery to high precision devices. This type of bearing consists of four elements that include an inner ring, an outer ring, a cage containing balls, and ball bearings. Due to the flat surface of the outer ring and inner ring, deep groove ball bearings provide a larger contact area providing high performance and high load capacity. Although deep groove ball bearings come in hundreds of designs and sizes with different designs and even different materials used in the inner ring, outer ring, and cage, they are basically classified into 4 main sections. TYPES OF DEEP GROOVE BALL BEARINGS Based on different designs, structures and ultimately applications, there are mainly 4 types of deep groove ball bearings. Let's see what these deep groove ball bearings do and what is the main difference between them. Single row deep groove ball bearings In this particular type of deep groove ...

Solid Lubricant vs. Oil Lubricant - What’s the Difference

Image
  The constant friction in the bearings generates heat. Over time, this will deteriorate the bearing and significantly reduce its life. Bearing lubrication plays a key role in separating moving parts, minimizing friction, and preventing continuous wear. As such, bearing lubrication is one of the most important aspects in maintaining and extending bearing life. Lubricants also serve to reduce corrosion and protect against contaminants that would otherwise damage bearings. By including regular inspections and lubrication in bearing maintenance, it is possible to improve the functionality and reliability of each bearing , reducing the risk of corrosion failure. What are the differences between a solid lubricant and an oil lubricant? There are two main subsets of bearing lubricants: solid lubricants and oil-based lubricants. Solid lubricants Solid lubricants are oil-filled microporous polymers. They are ideal for reducing friction and preventing wear, especially in situations w...

Bearings in the Food Processing & Packaging Industry

Image
  Many industries focus on food. For example, the agricultural industry deals with the growing, harvesting and preparation of fruits and vegetables for distribution, while the catering industry deals with the preparation and service of meals in local restaurants. These two industries are distinct from the food processing and packaging industry, which processes food after it has been processed by agricultural facilities but before it is distributed to catering facilities. Basically, any food that enters a production facility falls under the dominion of the food processing and packaging industry. Thanks to population growth and rising incomes, the demand for food has increased dramatically over the years. Meeting this demand requires investing in food processing and packaging equipment that can improve efficiency, lower costs, and reduce downtime while meeting all FDA and health requirements. Choosing the correct bearings is critical to achieving these goals.   What bearings...
