The hidden side of needle roller bearings.

 


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, size and weight.

For example, a needle roller bearing can support 2 to 8 times a load of ball bearings or cylindrical roller bearings for the same shaft diameter - all in a small footprint.

For which application?

Depending on the area of use and application, the needle roller and cage assembly can be integrated between rings that stiffen the structure and ensure the connection between the various mechanical parts.

Needle roller bearings are therefore available in many forms (cages, bushings, bearings with solid rings, combined bearings, needle roller thrust bearings, cam followers, etc.) to meet all the technical requirements of industrial markets.

These bearings, which combine robustness, precision and durability, concern all industrial markets and are particularly present in the following sectors:

- Automobiles,

- two-wheelers,

- Portable tools (drills, chain saws),

- construction machinery,

- pumps and motors.

Know-how and high performance

The design, development, and manufacture of needle roller bearings are a matter for specialists. Because smaller, lighter, always equally precise, and often invisible, needle bearings are ubiquitous in our everyday lives. Unnoticed, they guarantee operators the proper functioning of their equipment, which is necessary for its productivity and performance.

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.

Bearing Life Cycle

Image
  Each bearing has a certain potential for life. However, research has shown that, for various reasons, not all bearings achieve this. Important milestones that have a major impact on the life of a bearing can be recognized during the life cycle of the bearing. These steps are assembly, lubrication, alignment, basic condition monitoring, and disassembly. The life cycle stages of a bearing are extremely important to achieve maximum service life. By applying good maintenance practices and using the right tools, you can dramatically extend the life of your bearings and increase plant productivity and efficiency. Help your bearing reach its maximum life! Mounting: Mounting is one of the critical stages in the bearing life cycle. If the bearing is not mounted correctly using the correct method and tools, the bearing life will be shortened. Individual applications may require mechanical, thermal, or hydraulic mounting methods for proper and efficient bearing mounting. Selecting th...
