Because it is so very tiny it has to be handled with extreme care.  This means the bearings are generally packaged in Class 100 clean rooms (very clean rooms indeed) and must be handled wearing surgical gloves because of the tiny amounts of acidic content on human skin.  During assemblage, workers must wear shoe covers, smocks and clean-room specification caps.  Makeup is band in these areas.

The 6005 bearing is a common and widely used bearing model. Understanding its inner diameter, outer diameter, and width dimensions is crucial for selecting the appropriate bearing. Based on your application requirements, load, speed, temperature, and quality criteria, choose the suitable size of the 6005 bearing for your application to ensure good performance and reliability.

The outer diameter of the 6005 bearing is 47 millimeters. This refers to the diameter of the outer ring of the bearing. Make sure that your application space can accommodate the outer diameter of the 6005 bearing.

Application Environment: Determine potential sources of contamination and other external particles in your application environment. Depending on the environmental conditions, choose between open type, metal shields, or rubber seals to provide the appropriate level of protection.

The 6005 bearing is also used in electrical tools, fans, motors, and other electrical equipment to ensure their smooth and efficient operation.

6005OPEN, 6005ZZ, and 6005 RS are bearings with different types of outer covers, providing varying degrees of protection and support. Depending on your application environment, precision and speed requirements, as well as maintenance needs, choose the appropriate outer cover type to ensure the normal operation and prolong the lifespan of the bearing.

Indicating the sealing method of the bearing. "R" represents a bearing with a single rubber seal, while "2R" represents a bearing with two rubber seals.

The width of the 6005 bearing is 12 millimeters. This refers to the distance between the inner and outer rings of the bearing. Ensure that this dimension is suitable for your application to ensure proper installation and operation.

These tiny bearings are commonly used in precise hand-held medical and dental equipment.  They’re also used in watches, clocks, micro-motors and micro-machines like model cars.  The bearings can withstand pretty high loads and are covered with special shielding to decrease contamination and improve strength.  The shield is designed to allow for lubricant whilst prevent debris getting in.

The 6005 bearing is typically composed of an inner ring, outer ring, ball elements, and a cage. The groove in the raceway is slightly larger than the radius of the steel balls. Due to the point contact between the balls and the raceway, the 6005 bearing can withstand both axial loads in both directions and radial loads. It is commonly used in pairs under normal conditions to minimize the internal axial forces caused by the load and to primarily handle radial loads.

This tiny ball bearing design proves how versatile the ball bearing is.  From the largest ball bearings in use which prevent earthquakes to the tiniest which allow medical professionals to save lives we really would be in a different place without our friend the ball bearing.  The tiniest ball bearing is just another one of those feats of engineering to marvel at.

6005ZZ refers to the 6005 bearing with metal shields as the outer cover. The metal shields effectively block dust, contaminants, and other external particles from entering while retaining the lubricant within the bearing.

The 6005 bearing plays a crucial role in various parts of the automotive industry, including automobile engines, transmissions, wheel hubs, and power windows, ensuring the performance and safety of automobiles.

Maintenance Requirements: Take into account your maintenance needs for the bearings. Open-type bearings require regular cleaning and lubrication, whereas metal shields and rubber seals can reduce the maintenance requirements.

In this article, we will explore the significance of the ball bearing size chart and understand how to interpret and utilize it effectively.

Small bearings don’t come much smaller than this one in a fidget spinner (opens new window).  The bearing sits comfortably on a grain of rice with an outside diameter of 1.5mm, an inside diameter of 0.5mm and a width of 0.65mm.  It’s about the size of a lead of a pencil but can rotate impressively fast (over 5,000rpm).  The bearing is made from 440C stainless steel with six ball bearings.

6005 OPEN, 6005 ZZ, and 6005 RS are different outer cover modes of the bearing. In this article, we will introduce these outer cover modes to help you choose the appropriate bearing protection method that suits your needs.

The 6005 OPEN type bearing cover is a design without a cover, allowing the internal components of the bearing to be exposed to the external environment. This design makes the bearing more susceptible to contamination from dirt, dust, and other external particles.

Ball bearings don’t come in all different shapes, but they do come in all different sizes.  If you know anything about ball bearings the miniature ball bearing will be reasonably familiar, but chances are you’re unlikely to have come across a ball bearing as small as the one featured in this article.  The world’s biggest ball bearing in use is 12 feet in diameter and weighs between 40,000 to 50,000 pounds, a pretty impressive size, but it’s arguably the tiniest ball bearing in the world which is the most astonishing feat of engineering.

In modern industrial applications, bearings are indispensable components responsible for supporting and reducing friction in mechanical parts, ensuring smooth and efficient system operation. Among these, the 6005 deep groove ball bearing plays a significant role in contemporary industry. Let's delve into this bearing known as 6005 and understand the outstanding performance it brings to various applications.

Indicating the sealing or protection method of the bearing. "Z" represents metal shields, and "2Z" represents a bearing with two metal shields.

This may give the impression that ultra-miniature ball bearings are very delicate, and though they are in manufacturing, once in place the bearings are designed to withstand harsh conditions.

6005 RS refers to the 6005 bearing with rubber seals as the outer cover. The rubber seals provide enhanced protection by effectively blocking moisture, dust, and other contaminants from entering. This sealing method is commonly used in harsh environments and applications that require stricter protection.

The 6005 bearing is a type of deep groove ball bearing, and its model number represents its dimensions and performance characteristics. In the model number, the "6" in "6005" represents the bearing series, and "005" represents the specific model.

Precision and Speed Requirements: Consider the precision and speed requirements of your application for the bearings. Open-type bearings are typically suitable for low-precision and lower-speed applications, while metal shields and rubber seals provide higher protection and are suitable for applications with medium to high precision requirements.

It is commonly referred to as "bearing" in English, while in Taiwan, it is usually called "軸承". The fundamental principle of a bearing involves the placement of rolling elements, such as balls, needles, or rollers, between the inner and outer rings to facilitate smooth rotation of the shaft.

A sleeve bearing (also known as a bushing bearing or plain bearing) is a straightforward and fundamental type of bearing. It primarily consists of an inner metal sleeve (known as the bushing) and an outer metal sleeve. Between these two sleeves lies a layer of special lubricating material, typically a sliding surface coated with grease or oil.

In industrial equipment, the 6005 bearing is widely used in applications such as wind turbines, machine tools, pumps, and gearboxes.

The 6005 bearing may quietly play a role in many industrial applications, but its outstanding performance and reliability make it the preferred choice for engineers and manufacturers. Whether your requirements involve high load capacity, high-speed operation, or quality seal design, the 6005 bearing can meet your expectations. If you are looking for reliable bearings to enhance your equipment's performance, the 6005 bearing is definitely worth considering.
