The factors for purchasing imported bearings and the method of bearing selection:
1, can be separated from the bearing (accuracy)
This is a kind of bearing that can be separated by the ferrule; when both ferrules are used tightly, the strength is very outstanding. The bearing company can choose the double-row angular touch ball with four-point touch ball bearing and double half inner ring. Bearings, cylindrical roller bearings, tapered roller bearings, thrust ball bearings, thrust cylindrical roller bearings and thrust spherical roller bearings. Bearing company navigation 2, the length of the sliding cooperation can not be separated from the bearings (such as deep groove ball bearings and tuning Heart roller bearings can also be used as swimming bearings. One of the two ferrules of this type of bearing is cooperative; there is no axial fixed surface. Therefore, one ferrule of the bearing can move on its bearing surface. Bearing company navigation 3 The length of the bearing itself compensates for the support of a shaft and the bearing usually adopts the layout of the fixed bearing and the movable bearing combination. The swimming bearing compensates for the length error and thermal expansion of the shaft. The automotive bearing type query software bearing international NU type and N type cylindrical roller The bearing is an aspirational swimming bearing; these bearings can compensate for the length. The inner and outer rings of the bearing can be used tightly. The bearing type of the bearing is inquired by the software bearing international 4, bearing Axial load The primary bearing that accepts axial load is usually a thrust bearing; its nominal touch 旮旯A0"450. Thrust bearing and thrust angle touch ball bearing can accept axial force in one or two directions together according to different layout. It is preferred to use thrust cylindrical roller bearings and thrust spherical roller bearings when receiving high force. Automobile bearing type query software bearing international thrust spherical roller bearings and one-way thrust angular contact ball bearings can accept axial load and diameter together To the load; other thrust bearings can only accept axial load. Automotive bearing type query software bearing international 5, bearing radial load The bearing that receives radial load is the radial bearing. The nominal touch angle of this type of bearing A0 "= 450. The rain-like roller bearing can accept more radial loads than the ball bearing. The N-type and NU-type cylindrical roller bearings of the automotive bearing type inquiry system can only accept radial load; other types of radial bearings can accept the diameter. Toward the load; can also accept axial loads.

1.Quality pass Germany TUV testing. Tuv testing is third safety certificate company,.more authoritative.
2. This system welding machine use Surface Mount System to install electron component and the main PCB board is single .So this system could make the machine`s quality is very stable. Rise the quality consistency.
.
3.The power tube of the switch use germany infineon only.The PCB board thickness size is 2.7mm.
4.The insert component use Taiwan KSS.
5.The aluminum web wing is more bigger and weighter than normal.
6.Passed EMC certificate and get the EMC certificate. According to IEC 60974-1 standard.
7. Our machine`s input voltage is auto change between 85V-240V.So could work under any voltage. Like japan 110V or America 110V AC. Like European 220V-240V AC. Like Brazilian 110V/220V together AC.
8.CEL. Could weld Cellulose electrode easy.
9. Welcome any customer to make your design. We have advanced exploit troop.
10.PFC (Power Factor Correction is more than 98%. So according to energy conversation ,environmental protection and low-carbon.
11. VRD make no-load output voltage under 24±2V, But when arc strike twinkling could rise working output voltage.So this technique could have more physical protection.
