Take the sphere bearing (insert bearing with housing) outside the stand It is a kind of bearing unit combined rolling bearing with bearing seat. Make the external diameter into the sphere, install with the imported bearing seat with inner hole of ball-shaped together with sphere bearing outside the majority, the structure is various informative, commonability and interchangeability are good.

Meanwhile, this kind of bearing must adjust the disposition in the design too, it is apt to install, the seal installation with double structure, can work under the abominable environment. The bearing seat usually adopts and casts shaping. The daily seat has vertical seats (P) , square seat (F) , the square flat (FS) of protruding platform , the round flat (FC) of protruding platform , rhombus seat (FL) , annular seat (C) , slippery seats (T) When.

Lead outside one the sphere bearing is lubricating grease sealing deep ditch ball bearing and bearing seat associations of different shapes and high-accuracy assembly products become. The intersection of bearing and assembly can install at the subject to reach the mechanical device directly through several bolt, adjust heart functions, the ones that can pay lubricating grease are supplementary,etc., it is one kind that installs and uses very simple and convenient products.

Though its basic performance and deep ditch ball bearing should be similar, this kind of bearing is mostly applied to more coarse machinery, install, make a reservation enough accurate, axle and flat axis of hole to neutral and poor, either axle long and under the situation whose deflection is great, and own precision of bearing is not high enough either, some structure is more coarse, suitable discount at actual the intersection of behavior and the same dark ditch ball bearing of specification of performance play. For example: The exterior sphere ball bearing with a silk is applied to the large leading to the axle of bad deflection of rigidity, this kind of bearing two wears and seals enclosing, can prevent the filth from invading tightly, the sixth of the twelve Earthly Branches fills right amount of lubricant while dispatching from the factory, does not need to wash before installation, did not need to add lubricant, carrying the silk screw on the protruding end of inner circle of bearing is while fastening on the axle. The axial load allowed can’t exceed 20% that amount moved load. The exterior sphere ball bearing with off-centre set is essentially identical with exterior sphere bearing performance with a silk, do not just carry silks on the inner circle, but put in off-centre in. The inner hole of sphere ball bearing is a strip 1 outside the taper hole: 12 the intersection of taper and hole of conical degree, can install at cone-shaped axle directly, until the bushing is installed in having the axle shoulder optical axis definitely closely, and but fine setting bearing backlash.

The exterior sphere bearing is suitable for requiring apparatus and spare part simple occasion preferably, for example used in agricultural machinery, transportation system or building machinery. Mainly used for bearing radial and axial union load relying mainly on radial load, should not generally bear axial load alone, this kind of bearing can differentiate the inner circle of installation (bring to the whole group and roll son and keepers) With the outer lane. This kind of bearing does not allow the axle the foreign shell has slope, will produce additional axial force under the circumstances that radial load is appointed. The the intersection of bearing and axial size of backlash, will you please the normal work relationship very much loud to bearing, as the axial backlash passes for hour, Wen Sheng is relatively high; When the axial backlash is bigger, the bearing is easy to damage. So pay special attention to adjusting the axial backlash of the bearing while installing and operating, can cross and full of installing in advance if necessary, in order to increase the rigidity of the bearing.

The name of product: Import NTN.NSK.SKF YAR212-2F original packagingly and lead the new type of ball bearing of sphere outside one: YAR212-2F old type: 390512 internal diameters: 60( mm) External diameter: 110( mm) Bearing material: High-carbon chromium bearing steel (quench completely type completely) (GCr15) Use: Common Type: Take the sphere ball bearing outside seats
