characteristics of the multi- row angular contact ZYS ball bearing

Zhejiang  ZYS taper roller bearings  distributor, professional sales agents  bearings,  bearings provide customers with quality products that help companies reduce costs, improve economic efficiency and other aspects of business has made tremendous contributions. We learned from the Zhejiang distributor of Bearing , Japan  Bearing Corporation announced : In order to adapt to the ball screw support machine part , developed to achieve " world's largest " load capacity of multi- row angular contact ball bearings and machine tools as bearing "ULTAGE" series of product supply .
Here we follow the   bearings distributor, to understand the mechanism and characteristics of the  multi- row angular contact ball bearings :
multi- row angular contact  ZYS Sealed bearing ball through increased size and maximizing the number of balls , improve the load capacity and rigidity , longer product life , because with both sides sealed , so no installation bearing cleaning , degreasing and lubricating plus oil processes. In addition, the pre- sealed bearings have a long life oil , no way to add fat . Moreover, the mounting bolt holes located in the outer ring , bearing box is easy to install . Since the sealing lip and the improvement it can only result in increased friction loss torque . ( Zhejiang NTN Bearing editor )

Finally , Beijing Tsinghua University student Liu Fangfang Year award on behalf of the winners , and Tsinghua University to leaders and teachers to express my sincere gratitude and expressed his unreserved dedication to the motherland learned , determination and dedication to the community.

To actively respond to national call for the elimination of ,ZYS Bearing Test Machine production capacity

Cixi : within two years of high energy transformers "laid off "
WASHINGTON ( Reporter correspondent Zhang Lu Li Li ) Recently, the City Power Supply Bureau powered by city staff came Yu Bo community , the community S7 -type high- energy transformer replacement for the new energy saving amorphous alloy distribution transformers , reduce power loss. So far, over 35 units within the city limits S7 ??-type transformers are replaced with high energy saving and environmental protection -type transformers.

To actively respond to national call for the elimination of ZYS Angular contact ball bearing  production capacity , accelerate the construction of new rural electrification , increase the energy saving new equipment applications . Recently, the City Power Supply Bureau launched a comprehensive high-energy transformer replacement work , a new round of rural power grids in the process of implementation of the elimination of old transformers work .

It is reported that the original transformer used for the S7 -type transformers, is the 1980s products , power loss, has been unable to further meet the increasing distribution network power quality and reliability , and vigorously promote the new ZYS Precision Bearings energy-efficient distribution transformers is imperative. In this high-energy transformer replacement work , S7 -type transformers will all be replaced with new energy-saving transformer - saving amorphous alloy distribution transformers . Energy amorphous alloy distribution transformer "posts ", the 10 kV line to reduce line loss rate . This is a loss of the transformer itself is only a year can reduce the energy loss of about 30 million kilowatt hours and reduce carbon emissions of approximately 265 tons .

ZYS ball bearing With a high pressure oil pump through the nozzle hitting insert ball bearing

Oil lubrication method comprising :
1 drip lubrication
Drip lubrication oil rationing was needed for spherical roller thrust bearing components , usually every 3-8 seconds drip drop amount is appropriate , too much oil will cause bearing temperature increased.
2 cycle oil lubrication
The filtered oil pump feeding oil to the bearing member , through the bearing lubricant and then filtered after cooling to use. As the cycle oil can be taken away some heat , so cooling  insert ball bearing and therefore law applies to high speed bearing components.
3 oil bath lubrication
Oil bath lubrication is the most common method of lubrication , suitable for low- , medium-speed bearing lubrication , spherical roller thrust bearing part of the dip in the tank , oil from the rotation of the bearing parts brought up , and then back into the oil sump should be slightly lower than the center of the lowest rolling element .
4 jet lubrication
With a high pressure oil pump through the nozzle hitting the bearings , INA bearings in oil injected into the other end of the bearing into the tank through . When the Rolling mill bearing is rotating at high speed , the rolling body and the retainer are relatively high rotational speed of the surrounding air to form an air flow difficult with the general method of lubrication oil to the bearings , then the lubricant must be sprayed with high-pressure injection method to thrust spherical roller bearings , the position of the nozzle should be placed between the inner and maintaining aircraft center.
5 spray lubrication
With dry air formed by the spray mist mixed with oil , jet thrust spherical roller bearings, air bearings can effectively make INA cool and prevent intrusion of impurities . This method is suitable for high-speed, high-temperature lubrication of the bearing components.
