Steel cage spherical Roller Bearing, which have two rows of barrel shaped symmetrical rollers, and held in a brass cage without fixed middle block. a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis .Therefore, spherical roller bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, The center point of the sphere in the outer ring raceway is at the roller bearing axis. modified line contact between rollers and internal & external ring to achieve maximum loading capacity. mainly bear radial load.
Feature:
Both the dynamic load rating and rating life equations contain no difference regarding cage design and material (brass or steel).
Design used for medium size bearings operating at medium to high speeds and featuring high load carrying capacities
Two-piece window type pressed steel cage guided on the inner ring
When the rolling bearing is equipped with a steel cage, hard contaminants might appear as a result of the adhesive wear at the cage-rolling element contact.
Consequently the cage design has evolved to achieve higher and higher bearing load rating capacities, by incorporating more rollers, and lower costs, by replacing brass with cheaper low carbon steel, probably also for reasons connected to the economies of scale pursued by the biggest bearing manufacturers.
APPLICATION:
Spherical Roller Bearing are available with heavy duty rollers and cages that are suitable for extreme demand harsh applications such as vibratory screens. Mining Conveyor Machine, and mining bulk Conveyor Pulley. In this sort of aggressive operational environment, the spherical roller bearing is the only type that delivers acceptable service life. generally have a longer life span than other bearing types.
To be the first class, to do the best quality, to make users satisfied, to ensure customers relieved, are our enterprise purposes. Welcome bearing dealers` and Conveyor Idler manufacturers contact from all over the world, and become our partner.

The development goal of China's gear industry is defined as "promoting China to become a manufacturing power and a major exporter of gears." Luo Baihui said that in the development process, China’s gear industry will have four major situations:
First, the market will have a large number of new gear products with international standards and independent intellectual property rights;
Second, the market will create a number of world-renowned brands of gear manufacturing companies, and many specialized SMEs will also enter the global procurement system and oem support;
3. The industry will organize professional gear trading platforms and organize exhibitions and business negotiation activities;
Fourth, the industry will adopt international advanced standards, establish independent experimental testing capabilities, set up reliable gear industry laboratories, and establish basic technical data platforms for gears, universities, research institutes, and enterprise technology centers to promote various enterprise gear products. Independent development. 
The Chinese gear industry will become a global gear manufacturing country in the next 10 years. According to Luo Baihui, head of the International Mould and Hardware & Plastic Industry Suppliers Association, from 2006 to 2010, China's gear manufacturing enterprises will shift from intensive management to information-based lean manufacturing, and the annual output value will reach 100 billion yuan, becoming the third largest global gear export. Even the second largest country, it is expected that from 2011 to 2015, as the gear product market matures, China will become a global gear power.
