Thrust Spherical Roller Bearing
A spherical roller thrust bearing is a rolling-element bearing of thrust type that permits rotation with low friction, and permits angular misalignment. The bearing is designed to take radial loads, and heavy axial loads in one direction.
Spherical roller thrust bearings are of separable construction, The shaft washer is assembled with the cage and a number of asymmetrical spherical rollers and has to be used along with a housing washer having sphered raceway. During mounting, the rings are to be fixed on to their respective seats – shaft washer on the shaft and housing washer on to the housing and then they have to be put together carefully They are manufactured in multiple series.

The latest data shows that the recent rare earth market continues to rise, and the market price continues to rise. At present, the mainstream price of bismuth oxide is 300,000 yuan - 305,000 yuan / ton, and the price of metal bismuth is 380,000 yuan - 385,000 yuan / ton. The current price of cerium oxide rose to 1.68 million yuan - 1.7 million yuan / ton, the price of cerium oxide rose to 3.8 million yuan - 3.9 million yuan / ton. The relevant suppliers basically have no willingness to ship, and the market is further improved after the quiet period, resulting in relatively tight supply in the market.
From a policy perspective, the Ministry of Commerce said on January 21 that since January 1, 2015, the export quota management of rare earths has been cancelled, and the export tariffs on rare earths expired on May 2. At present, the tariffs on light rare earth and heavy rare earth products are 15% and 25% respectively. As the WTO organization ruled that China's rare earth case lost, the export quota and export tariff policy will be completely revoked. Under the abolition of the export tariff policy, plans for rare earth resource taxes are expected to accelerate.
In general, the state attaches great importance to the value of rare earths, as well as the policy of strengthening the strength of the Ministry of Industry and Information Technology and the subsequent introduction of rare earth resource taxes. The rare earth market in the bottom region is welcoming the opportunity for profitability improvement. It is expected that the rare earth price is expected to continue to rise until the maturity of the rare earth tariff on May 2.
The raceway of the housing washer is at an angle with it`s ais of rotation, so as to be able to allow the rollers to remain in touch with it. As a result, a spherical roller thrust bearing is capable of carrying both a radial as well as an axial load. Spherical roller thrust bearings – because of their internal geometry – are capable of accommodating certain amount of misalignment. However, they can take axial loads only from one direction, and may need to be used in pairs in Back-to-Back or Face-to-Face arrangement, if thrust load from both the directions are to be carried.
Spherical roller thrust bearings are capable of compensating misalignment and shaft deflection.
The bearings are manufactured in normal accuracy. However, bearings with higher running accuracy can also be supplied.
Rare earth prices hit a new high of about 2% during the year
Abstract According to the information of the Shanghai Stock Exchange, on February 3, the varieties of rare earths were again increased by about 2%, a new high this year. Among them, light rare earth lanthanum oxide rose by 5,000 yuan per ton, up 12% since December last year; heavy rare earth cerium oxide rose by 150,000 yuan per ton,...
According to the Shanghai Stock Exchange, it was learned that on February 3, the varieties of rare earths rose again across the board, with a range of about 2%, a record high this year. Among them, light rare earth lanthanum oxide rose by 5,000 yuan per ton, up 12% since December last year; heavy rare earth lanthanum sulphate rose by 150,000 yuan per ton, nearly 4%, and the cumulative increase since November last year was nearly 40%. At present, the overall inventory of the industry is low, and the downstream goods are positive.
