Advantages of s694zz / s694-2rs - Yuwei stainless steel bearing

Release time: 2018-03-18 12:12:58 Views: 1903


Yuwei S694ZZ/S694-2RS Introduction of stainless steel bearing:
Yuwei S694ZZ/S694-2RS Used for bearing ring and rolling element material AISI SUS440C Stainless steel (domestic No 9Cr18Mo 9Cr18 )After vacuum quenching and tempering, the cage and sealing ring framework materials are made of AISI304 Stainless steel (domestic No 1Cr18 )。 S694ZZ/S694-2RS Stainless steel bearing and common bearing steel S694ZZ/S694-2RS Compared with, it has stronger anti rust and anti-corrosion properties, and can be used in the -60 ~+200 Under the environment of. stainless steel S694ZZ The bearing is equipped with dust cover. S694-2RS Contact seals are installed. Bearings with dust covers or seals on both sides are lubricated for life without maintenance. Stainless steel bearing is widely used in food processing, medical equipment and pharmaceutical machinery due to its high mechanical strength and large load capacity.



S694-2RS/S694ZZ Advantages of stainless steel bearing:

one Excellent corrosion resistance: stainless steel bearing is not easy to rust, with strong corrosion resistance.

two The stainless steel bearing can not be washed down with water to prevent rust.

three , can run in liquid: due to the materials used, we can run in the liquid bearing and bearing seat.

four The rate of depletion is slow AISI 316 Stainless steel, without oil or grease corrosion protection. Therefore, if the speed and load are low, lubrication is not necessary.

five Sanitation: stainless steel is natural and clean without corrosion.

six High heat resistance: stainless steel bearings with high temperature polymer cages or cages without a complete complementary structure can operate in a higher temperature range 180°F to 1000°F ( High temperature resistant grease is required )

Yuwei S694-2RS/S694ZZ The detailed parameters of stainless steel bearing are as follows:

internal diameter (d) 4mm external diameter (D) 11mm width (B) 4mm

Seal type : 1.ZZ (iron cover seal on both sides) 2.RS (sealed with two rubber covers) three Open seal without cover

Note: S694ZZ/S694-2RS The main materials of stainless steel bearings are: (martensitic stainless steel) :9Cr18 9Cr18Mo AISI440C Austenitic stainless steel: AISI304 AISI316 )It has good oxidation resistance, corrosion resistance and non-magnetic, especially suitable for harsh production environment, with large bearing capacity, long service life and maintenance free. among them, stainless steel bearings, rings and rolling elements are made of stainless steel as standard structure AISI SUS440C 9Cr18Mo or 9Cr18 )After vacuum quenching and tempering, the cage and sealing ring framework materials are made of AISI304.

cause S694ZZ/S694-2RS There are many reasons for stainless steel bearing rust corrosion, the main reasons are as follows:
First, some enterprises did not carry out anti rust treatment for bearing parts and finished bearing products after assembly in strict accordance with cleaning and anti rust regulations and oil seal anti rust packaging requirements in the process of bearing production. For example, the turnover time of the ring is too long, and the outer circle of the outer ring contacts with corrosive liquid or gas.
Second, the quality of antirust lubricating oil, cleaning kerosene and other products used in the production of some enterprises can not meet the requirements of process and technology regulations.
Third, as the price of bearing steel falls again and again, resulting in the gradual decline of bearing steel material. For example, the content of nonmetallic impurities in steel is high ( With the increase of sulfur content in the steel, the corrosion resistance of the material decreases ) And metallographic structure deviation. At present, the source of bearing steel used by production enterprises is more miscellaneous, and the quality of steel is fish dragon mixed bead.
Fourth, the environmental conditions of some enterprises are poor, the content of harmful substances in the air is high, and the turnover site is too small to carry out effective anti rust treatment. In addition, there are many workers who violate the production regulations in hot weather.
Fifth, some enterprises of antirust paper, nylon paper ( bag ) And plastic cylinder and other bearing packaging materials do not meet the requirements of rolling bearing oil seal anti rust packaging, which is also one of the factors causing corrosion.
Sixth, the turning allowance and grinding allowance of stainless steel bearing rings in some enterprises are small, and the oxide scale and decarburization layer on the outer circle are not completely removed.
Seventh, the so-called stainless steel bearings made by some enterprises are actually made of bearing steel and carbon steel, so they are easy to be rusted and corroded.


Yuwei company With advanced precision bearing production equipment and testing instruments, bearing products are strictly in accordance with GB/T307.1-2005 As standard , And is the only one of the bearing enterprises in China . And passed RoHS Environmental certification and material safety technology / Data sheet MSDS Therefore, there are strict production procedures for stainless steel bearings.
