1) And the antifriction bearing (18) is radially and constrainedly installed through a pressing cooperation, thereby the ball (25) no longer jump out of the bearing (18).

2) The graphite is a kind of solid antifriction agent with excellent properties.

3) Cast metallic matrix self-lubricating composites, which possess excellent antifriction, wear resistance, damping capacity, etc. , have been investigated extensively.

4) The wear resistance and antifriction qualities of the oil impregnated sintered bronze make for an excellent guide bushing .

5) Special formula for the rubber wheel, antifriction, aging resistance and high temperature resistance.

6) The special rubber wheel is of exclusive formula, antifriction, aging resistance, and high temperature resistance.

7) The three basic types of antifriction bearings are ball bearings, roller bearings, needle bearings.

8) In order to strengthen its antifriction property, the material nature of the boards chooses a special formula of high molybdenum, high chromium and nickelic.

9) Therefore, the main function of antifriction bearing lubricants is to help prevent corrosion and dirt contamination.

10) Advantage: Strong intensity, antifriction , wearable, anti - rotten, acid and alkali resistant, simple and portable, safety and applicable.

11) Using antifriction bearing and hard alloy for guiding and saw blade overload protection device.

12) According to the analysis of the performance of antifriction by using abrasion tester, coefficient of friction and wear loss were measured on the conditions of regular feeding oil and no oil.

13) The structure of import antifriction paper is discussed by means of SEM and other techniques.

14) Stabilization and antifriction of the rod string in horizontal hole are of great importance.

15) High-sulphur steel self-lubrication new materials is studied. Service life of guide roll of mill is raised by self-lubrication antifriction of metal sulphides.

16) The reformed one has a feature of reasonable structure, high antifriction and reliable safety, which are the first well head equipment to be taken in fracture operation.

17) Analogue computation and experiments show that employing compound oil film damper in antifriction bearing spindle system will raise significantly the dynamic behavior of machine tool.

18) It had good ability of controling deposit formed in highcondition,(http:///antifriction.html) anti oxygen and antifriction.

19) The results show that ZA27 alloy is a good antifriction material in lubrication.

20) It used thick film technique with good endurance to diesel oil, causticity to gas and antifriction performance.

21) The results show that the ASB materials are the new PM antifriction materials for aerobat.

22) The lubricating oils containing organo - molybdenum own the excellent properties of antifriction, antiwear, antioxidant and fuel economy.

23) Ag-G composites could display its self-lubrication and generated complete lubricate films while its antifriction reduced largely in N2.

24) Service life of guide roll of mill is raised by self - lubrication antifriction of metal sulphides.
