Spherical Roller Bearings are most suitable option for applications that need shock resistant components yet this is not the only quality these Bearings have. These Bearings can handle heavy loads because of their rings` alignment. Due to the curved outer ring, Spherical Bearings come with self aligning capabilities that make it possible to absorb shocks and also enable the apparatus to carry high axial and radial load even in harsh environment with lot of vibration. Even with this rugged working environment, Roller Bearings tend to have high precision.

Spherical Bearings have two rows of rollers that are separated by a cage or rib that could be sealed or unsealed depending on the specific model and application, external raceway and dual raceways in inner ring to support rotating shaft. Amazingly the quality and alignment of raceways, cages and rings define the overall performance and quality of the product. Asymmetrical rollers increase performance and precision while symmetrical rollers offer better load distribution, lesser vibration that ultimately leads to durability.
MATERIAL
These Bearings are manufactured with several kind of material based on the application and working environment. Chrome steel is one of the most popular materials used in production of these Bearings because of its durability yet sheet steel, polyamide and brass are also used for some applications. One of the most important parts of Spherical Bearings is the cage that holds bearings at their place. That cage is usually manufactured with pressed steel or brass because both of these materials offer strength as well as temperature resistance.
These Bearings tend to have seals in order to prevent contaminants like dirt, liquid, debris as well as harsh temperature. This type of these bearing doesn`t even need lubrication if they do not exceed 50% of their maximum allowed RPM.
APPLICATIONS
Spherical Bearings are essential part of heavy machines like gearboxes, turbines, mechanical fans, constructions equipment, mining equipment and drilling equipment. Roller Bearings are available in multiple standard sizes and dimension yet they are also made with custom sizes and specifications.

MODELS AND VARIATIONS
Usually these Bearings come in two different types that have totally different design, structure, specifications and applications.
Single Row Spherical Roller Bearings
These are also known as Barrel Bearings because of their design and they are widely used where only low radial load carrying capacity is required. Other than the load capacity difference, Single Row these Bearings is quite similar to their counterpart in terms of performance and durability.
Double Row Spherical Roller Bearings
These are used where high radial load carrying capacity if required and that make them an essential part of almost all heavy duty machinery out there. The design difference between these two is obvious; Double Row Roller Bearings come with central flanges that optimize the overall performance of the apparatus.
Prospects for plastic packaging are improving, and innovative raw materials and processes are emerging one after another.
In December last year, China Packaging Federation formulated the “China Packaging Industry Development Plan (2016-2020)â€. The plan points out that by 2020, the localization rate of green and high-performance packaging materials will reach more than 35%; more than 60% of food and drug packaging production information can be inquired, the flow can be traced, the responsibility can be traced, and the expired can be recalled; some high-end Packaging products and related technologies have reached the international leading level. By then, the annual revenue of China's packaging industry is expected to reach 2.5 trillion yuan.
As one of the four major packaging materials, China's plastic packaging business (including plastic packaging boxes and containers and plastic packaging film) revenue in 2015 was about 274.9 billion yuan, accounting for more than 15% of the packaging business. Plastic packaging is also leaping in the direction of green, smart and efficient. Plastic is one of the four basic materials for packaging, and packaging is the largest area for plastics applications. In order to meet the demand for packaging, such as reduction, reliability, responsibility, and individuality, innovative materials and processes are constantly emerging.
Food and beverage packaging
According to UK market research firm Smithers Pira, the global soft plastic packaging market will grow at an average annual growth rate of 3.4%, with 70% demand coming from the food industry, reduction, lightweight, barrier technology, and biology. Degradability and sustainable development have become major trends.
In order to further strengthen food safety supervision, the National Health and Family Planning Commission and the Food and Drug Administration jointly issued the “General Safety Requirements for Food Contact Materials and Products in Food Safety†(GB4806.1). -2016), covering 53 relevant standard systems. Among them, the plastic resin for food contact, plastic materials and products, rubber materials and products, and a variety of organic substances that are potentially harmful to the human body have been clearly defined. The introduction of this regulatory system has attracted great attention from the industry and will play an important role in promoting the safety of food packaging materials, including plastics.
In addition to safety, innovation and personalized design are the focus of food and beverage companies, and innovative packaging has been launched to match product appeals and promote sales. For example, Nongfu Spring has launched a cylindrical square “tea π†innovative bottle type, which has been listed for one billion months and became one of the most successful large single items in 2016.
Daily packaging
The innovation of daily chemical product packaging lies mainly in functional packaging. In addition to the protective function, it is also required to gradually improve its safety and convenience. High oxygen barrier materials, moisture-proof materials, anti-counterfeiting and smart packaging are the main development directions. For example, the HD sunscreen bottle that won the 2016 DuPont Packaging Innovation Gold Award has three innovations: the fine mist nozzle, the easy-to-open “lock†and the wand technology that allows the nozzle to rotate freely, which is practical and beautiful.
Environmental protection, miniaturization of packaging or light weight have gradually become an important factor in daily packaging. In addition, packaging companies use more degradable and recycled materials, and recycle and recycle packaging waste.
