Corrosion-Resistance Alloy,mainly refers to ordinary stainless steel resists atmosphere and sea water corrosion such as 300 series stainless steel including 304,316L, 317L etc.; comparatively strong corrosion resistance material including austenitic stainless steel 904L, 254SMOand Dual phase steel 2205,2507 etc.; Corrosion Resistant Alloy containing Cu 20 alloy; In comparison to non-metal corrosion resistant materials, corrosion-Resistance Alloy main refers to iron alloy (resistance to corrosion); nickel alloy (Ni-Cr alloy, Ni-Cr-Mo alloy, Ni-Cu alloy and other active metal.

For needle roller bearings without inner ring or without outer ring; in the case of equipment; first apply a thin layer of grease to the roll surface of the shaft or housing hole; and place the needle roller in close contact with the grease on the device. When placing the final needle, leave a gap; the thickness of the gap should be 0.5mm on the circumference of the needle bearing. Never squeeze the final needle into it; perhaps install a roller. Needle; due to hard extrusion; the bearing will be stuck and can not be rotated, when installed less; the gap is too large; easy to form the bearing operation when the needle is twisted and broken. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Here is a unique point; about the needle roller bearing as long as the outer ring is punched; because the outer ring wall is very sturdy, the scent of the scorpion is smashed and smashed. Because of the hammer hitting; the pressure is uneven; The outer ring of the needle bearing is partially deformed.
The device is fully loaded with needle bearings; usually with an auxiliary sleeve. At this time; the auxiliary roller or the auxiliary sleeve holds the needle without the needle falling out; the journal picks up the needle with its own chamfer; The needle bearing gradually moves inward on the journal; the auxiliary roller or the auxiliary sleeve gradually withdraws; until the loading direction stops.
The outer diameter of the auxiliary roller and the auxiliary sleeve should be 0.1D0.3mm smaller than the shaft diameter. When the device is installed, the inner and outer surfaces of the bearing outer ring should be coated with grease; the inner and outer surfaces should be placed with the needle roller (put the final needle) Should leave a gap); then push the auxiliary roller or the auxiliary ring of the bearing inner ring into the outer ring hole; and align the end face with the end face of the device or the bearing inner ring that has been mounted on the shaft End face; then use a press or hand hammer to hit the applied pressure.
The needle bearing can also be installed in this way; the outer diameter of the auxiliary sleeve is coated with a thin layer of lubricating oil; the outer ring of the bearing is inserted; the auxiliary sleeve and the outer ring of the bearing form an annular hole; and then the needle is placed in the annular hole. After loading the needle roller, use the working shaft to push the auxiliary sleeve out.
