NTN imports to the technological characteristic of ball bearing of heart thrust


30th January 2010 Bearing Technology 0 Comments
To the intersection of heart and the intersection of thrust and for bearing of separating etc., with enclose, contact some link straight line with radial, form, keep in touch corner by a radial while being internal and external steel ball ball bearing NTN. Contact angle serial number and angle of NTN bearing are as follows Exposed to the angle 40 degrees for 30 degrees for 15 degrees Arrange number C A B It is that the standard contacts the angle to be exposed to the angle A, so will not reveal in NTN bearing type. NTN can also bear greater unidirectional axial load besides radial load to ...

Technological analysis: The performance of electrical machinery bearing lubricating grease is required


30th January 2010 Bearing Technology 0 Comments
1 The adaptability is good, have high low-temperature performance, can be inside and outside the room, common in the South and the North. 2 Person who lubricate, resist person who rub to be kind, get rid of oil, dry up, emulsify, run off, lubricating grease should contain firm the intersection of shape and thing. 3 Anti-oxidant and of good performance, after long term administration, one degree of changes of appearance color, acid soda of lubricating grease is little, have not obviously oxidized the phenomenon. 4 Flowability fine,if you can't demand generally, use ...

NTN bearing type expresses


27th January 2010 Bearing Technology 0 Comments
The bearing type of NTN shows: Code in key elements such as bearing type, size, precision, internal structure,etc.. And subsidize the code to form by the basic type. Its basic type is to express the pattern of NTN bearing, the code in basic contents such as the main size,etc., by the serial codes of the bearing, internal diameter code and exposed to the angle code to make up. Subsidize code by leading to subsidize code Prefix And subsidize codes Suffix in follow-up Form, express specifications such as the backlash,etc. within the bearing. ...

NTN adjusts the performance characteristic of the heart ball bearing


27th January 2010 Bearing Technology 0 Comments
A central point keeps the same with NTN central point that the outer lane sphere that NTN adjusts the heart ball bearing automatically rolls. It is listed that the inner circle has pair to roll one. The steel ball while rotating, keep the shelf, the freedom that the inner circle can do a certain degree to the mandrel of the outer lane slopes. Namely have the so-called adjusting heart performance automatically. So, can adjust axle and bearing case because of the processing, improper axis skew that takes place of installation automatically. Limited because of axial load ability, NTN adjusts the ...

The relation between material and performance of the bearing is analyzed


27th January 2010 Bearing Technology 0 Comments
The choice of the materials of the bearing has definite influence in bearing performance. One set of circles and rolling body of the rolling bearing, suffers high and exposed to the pressure repeatedly on one side, one side goes on in company with having rolling contact slipping. Person who keep, one side and sets of circle and both sides to roll body, or the intersection of and one party its slip and keep in touch, side suffer pulling force and contractile force. Therefore, to one set of circles of the bearing, roll the body and maintain the materials, performance, important request of the ...

Application of the deep ditch ball bearing Safeguard and maintain


27th January 2010 Bearing Technology 0 Comments
Since reform and opening-up, have broken out from the internationalized competition with our accession to the WTO gradually, bearing trades of China have been all developing steadily and fast all the time. According to the annual report of State Statistics Bureau, the non publicly-owned enterprises of more than 5 million yuan of state-owned and state holding enterprises of Chinese bearing trade and annual sales amount have been already up to 927 in 2004, the whole trade bearing output is 4,100 million in 2003, income from sales of the bearing is 39,200 million yuan, Chinese bearing sales ...

NTN bearing uses the material introduction


27th January 2010 Bearing Technology 0 Comments
NTN bearing needs while one set of circles bear greater stress with rolling the body and contacting the surface repeatedly, keep the high-speed precision rotating. One set of circles for this reason and rolling the body material to demand to possess the hardness high and resisting and rolling fatigue performance strongly, hard-wearing, and such characteristics as size stability is good. Nonmetal inclusion at most easy to guide tired and full of cracks. So the less nonmetal inclusion is, the more the material is cleaned, it is the longer to import the bearing life-span. Bearing of NTN adopt, ...

Daily bearing type on the lathe


27th January 2010 Bearing Technology 0 Comments
The high-accuracy angle is exposed to the ball bearing P4 rank, it is a specialized bearing on the main shaft of the lathe, the brand has SKF, NSK high-accuracy bearing, FAG main shaft bearing. This kind of bearing is especially suitable for leading the extremely high occasion of extremely high rotational speed, the main range of application is a lathe. The ball guide screw supports the bearing It is an intact unit that the ball guide screw of INA supports the bearing, there are the year in advances of integrated sealing and adjustment, it is simple and swift to install. In practical ...
