To ensure that the drafting process Cots flexible operation, reducing wear and the track groove ball bearing, extend the life of the bearing grease used to choose to use a long time, bear large film strength, wide application range, the viscosity is not hierarchical, not bad No. 3 does not flow extreme pressure lithium grease. It is understood that some companies have started using advanced jet fuel and the use of foreign senior Shell grease, not only to ensure good lubrication conditions, but also to the rubber roller bearing in 2-4 years without refueling and running.

In operation, the fuel injection can not be too large, to ensure that the second tranche of the ball at the grease, too much will cause the loss of fuel, oil pollution yarn faults, such as the infiltration of rubber at a rubber surface can cause swelling, from the dark, blistering, In particular, the surface does not deal with the hose, refueling over the general cause bearing wear, use special tools, dosing oil. Generally use the 3rd extreme pressure lithium grease 6 to 8 month cycle, control the amount of fuel in the new 4 g / sets, old is 2 g / sets.

Suggestions for use

First, the steel pressing grip portion length from 16.5 mm to 22 mm in diameter from 9.5 mm to 12 mm, in order to increase the accuracy of three-line parallelism. Second, steel center 68.33 mm spindle center 70 mm should coincide change 68.33 mm to 70 mm. Third, the outer surface of the trench change semicircle steel serrated aluminum liner to prevent slippage, should be actively test. Fourth, double slide should be actively test. Fifth, change lubricants for advanced aviation fuel or the use of senior Shell Oil, extended fuel cycle 2 to 4 years. Sixth, as the production of high-end products, sharpening tools A802 should be scrapped. Seven steel scrap is to establish standards, do not change in scrap iron rollers with rubber rollers.
