Bearing manufacturer USES and characteristics analyzed in detail

Bearing manufacturer use and characteristic in detail analyzed source: bearing | last updated: - 2020 06 - 20, 16008 / HR22T2 bearing manufacturer knowledge carding one-way bearing USES and characteristics of the detailed analysis summary one-way bearing has simple structure, convenient use, is the production batch, the largest's most widely used type of bearings. It is mainly used to bear radial load, also can absorb a certain amount of axial load. When bearing radial clearance increases, has the function of angular contact ball bearings can withstand teach large axial load. Compared with the same size of other types of bearings, such bearing small friction coefficient, high limit speed. In high speed under the condition of unfavorable use thrust ball bearing can use these bearings carry axial load. Specific classification and model comparison: 1. Open a one-way bearing ( The type 6000) Note: mainly used to bear radial load, but also bear the axial load of small, axial displacement limit within the scope of the axial clearance within the allowed relatively outer circle tilt. 1 - * 1/2, one-way bearing outer ring has a locking groove ( 6000 N) Note: the same base type one-way bearing load stop ring can simplify bearing axial positioning in the bearing hole 3, one side with dust cover, the other side one-way bearing outer ring has locking slot ( 6000 - Zinc type) 4, the two sides with dust cover, one-way bearing outer ring has a locking groove ( 6000 - Type 2 zinc) 5, a belt of dust cover one-way bearing ( 6000 - Z） 6, the two sides with a dust cover one-way bearing ( 6000 - 2Z） Note: with the base type one-way bearing dust cover with a space between the inner ring guard, same as the open one-way bearing limit speed has good seal bearing fill in the proper amount of lubricant, when it is assembled to install when using without washing and adding the lubricant. 7, a one-way bearing with seals ( 6000 - RS, 6000 - RZ type) Note: the same base type one-way bearing seal contact with the inner ring guard ( Post code % /, 。 /) And non-contact ( 。 # ( 。 #) , contact sealed effect is good, but the friction resistance is big, limit rotational speed is low. 8, the one-way bearings with seals on both sides ( 6000 - 2 rs, 6000 - Type 2 rz) Note: limit speed and non-contact seal open one-way bearing the same bearing fill in a suitable amount of lubricant to install when using when it is assembled without washing and add lubricant. 9, flange outer ring one-way bearing ( F6000 type) 10, a dust cover flange outer ring of the one-way bearing ( F6000 - Z) 11, two sides with dust cover flange outer ring of the one-way bearing ( F6000 - 2 z) Bearing the authenticity of five small tip 1. Bearing outer packing is clear: under normal circumstances, the original brand has its own professional designers design the packaging, and have the production conditions of the plant through the production schedule, so the packaging from the piece of the line, no doubt about it. 2. Seal is clear: the bearing will be printed with the brand name and label. Font is very small, but most of the products factory all use steel stamping technology, and suppress before heat treatment. So, although the font is very small, but it is a deep concave and very clear. Counterfeit products font is not only vague, but due to the rough printing technology, font floating on the surface, some even can be easily erased by hand. 3. If there is a noise: holding sleeve bearing subject with his left hand, and then turn the coat with the right hand rotation, listen to whether there is a noise. Because most of the counterfeit products production conditions, complete workshop by artificial operation, will inevitably in the process of production with the impurities such as sand and hid in the bearing, so the noises when rotating. With the strict production standards and on the machine running the biggest difference between the real factory brand. 4. Surface whether there is oil pollution: buy bearing should pay special attention to. Because of the current domestic antirust technology is not particularly popular, so after the antirust processing, it is easy to leave thicker oil stains on the bearing body, and feel very sticky, bearings imported from abroad are hardly found traces of anti-rust oil, but careful, experts say, bearing smells a bit smelly. It must be under the anti-rust oil, but it is not visible. 5. Chamfering whether uniform: bearing the so-called chamfering, namely horizontal surface and the vertical surface intersection, due to the limitation of production technology, counterfeit bearings on the Angle of process well.
