Angular Contact Spherical Plain Bearings As their name implies, the sliding contact surfaces of angular contact Spherical Plain Bearings are spherical in shape and inclined at an angle to the bearing axis . Consequently, these bearings are well suited for accommodating combined (radial and axial) loads. Single angular contact spherical plain bearings can only accommodate axial loads acting in one direction. These bearings can be separated, enabling the rings to be mounted separately.

manufactures steel/PTFE FRP (fibre reinforced polymer containing PTFE) maintenance-free angular contact spherical plain bearings as standard. Designs with other sliding surface combinations are available on request (Special designs).
LED filament bulbs have been around for six years since its creation. It was popular in Europe and the United States, and in China, the market has just begun. After the Guangya Exhibition this year, the LED filament light bulbs became popular, but in the Linyi market, there are still very few merchants selling LED filament bulbs. Among the merchants visited, most merchants operating LED filament bulbs are optimistic about their development prospects. Compared with ordinary LED bulbs, filament bulbs have many advantages. For example, ordinary LED bulbs have a maximum illumination angle of 180 degrees before adding other optical components, and filament bulbs can achieve 360-degree illumination; ordinary LED bulbs are made of translucent plastic. It has a dimming effect, and the filament bulb adopts a glass cover, which has higher light transmittance, reduces light energy loss, and is more energy-saving. The luminous effect can be comparable to that of incandescent lamps, and is more in line with consumer habits. One consumer said: The room where the bulbs (ordinary LED bulbs) are installed is not very bright. This is not a question of the quality of the light bulb, but the problem of the angle of illumination of the light bulb. Ordinary LED bulbs have a downward illumination angle that cannot be directly illuminated above the lamp. Especially when the bulb is far from the roof, the top is darker, giving the overall feeling is not very bright. The general LED bulb is installed in the European lamp and the crystal lamp. The effect is not as good as the incandescent lamp, because the illumination angle is limited. Some crystal lamps and European lamps also use incandescent lamps and spiral energy-saving lamps as the light source. LED filament bulbs are close to incandescent lamps in all respects, and energy saving is a better alternative. One dealer said that only the price of LED filament bulbs is relatively high, and there is no advantage compared with ordinary LED bulbs. In Linyi Lighting City, the author only saw several merchants selling LED filament bulbs. The products were mostly bubble bulbs and tail-blown bulbs, and there were few bulbs. The wholesale price of 1.8W and 2W double filament candle bulbs is around 16 yuan, and the wholesale price of 3.6W bulbs is over 30 yuan, while the wholesale price of ordinary 3W LED candle bulbs and 4W bulbs can be as low as 2 yuan. There is already considerable guarantee in the quality of about 7 yuan. Candles and pull-tails are usually placed on crystal lamps and European lamps. It is not expensive compared to a few high-end fifteen or six dollars. Besides, consumers don’t care. Go to your store to buy crystal lamps. When the European lamp is used, you can buy a few by the way. Compared with the price of the crystal lamp, the light bulb money is nothing, but the bulb is not the same. It is estimated that the LED filament bulb can sell forty or fifty dollars in the terminal. That would be too expensive. Whoever buys it can only be a high-end consumer. A dealer looks like this. Linyi Lighting City has always been known for its low price. Most of the merchants are mainly engaged in low-end products, and the price competition is extremely fierce. The price is too high, the wholesale volume will not be too large, and it will not be competitive. Therefore, at present, LED filament bulbs are mostly retail, and wholesale is still rare. Some manufacturers said that after a period of time, the price of LED filament bulbs can be reduced to about 10 yuan. Even so, ordinary LED bulbs still have a big advantage in price. The price is a short board of LED filament bulbs. It is estimated that it will take a long time to lower the price. In order to popularize it in Linyi market, low price is an important weight.
