 With outside Block Spherical Bearing is a roller bearing and the bearing of a combination of bearing unit. Most of the spherical bearings are made of the outside diameter sphere, imported bearings with a spherical hole seat installation with various forms of structure, versatility and interchangeability. 
 Kind of bearings in the design has a certain tone Mind, easy to install, has a dual structure of the sealing device can work in harsh environments. The bearing is cast molding. Commonly Block Vertical Block (P), the Square Tower (F), the Boss Square Block (FS), Boss Round Tower (FC), diamond-shaped seat (FL), annular seat (C), the slider Block ( T). 
 LNSERTED bearing type: 
 l, with a tight set screws spherical UC class bearing; 2, with a tapered bore spherical UK class bearings; 
 LNSERTED bearings are grease sealed deep groove ball bearings and various shapes bearing a combination of high-precision component products. Bearing components can be mounted directly on a few bolts to the main body of the mechanical devices, with the function of aligning, grease supplement, is an installation very easy product. 
 Why should I choose to import with Block bearings?

 Detection, the first NSK Bearings cover is open, the choice of the appropriate diameter of the wire will cut into 15 to 40 mm long pieces on the interface at the journal and the upper and lower bearings, cover the bearing cap, the torque required to tighten the fixing bolts, then loosen the bolts, remove the bearing cap detect flattening of the wire with a micrometer thickness, the average of the calculated bearing tip clearance. 
 If the headspace is too small, in the last tile combination of surface and pad. If too large, cut mats, scraped or poured tile. 
 Tight bearing force adjustment: bush may occur in the course of their work in order to prevent rotation and axial movement, interference with the only moving parts, the bearing must also NSK bearing cap to compress the measurement methods and measuring headspace measured the thickness of the soft lead wire, can be used to calculate the bearing tightening force (elastic deformation of bearing compression) 
 The general bearing pressing force in the 0.02 to 0.04 mm. If the pressing force is not standards-compliant, you can use to increase or decrease in the NSK Bearings and bearing joints at the gasket thickness to adjust, tile back is not allowed to padded. 
 Sliding NSK bearings to ensure that other than the radial clearance should also ensure that the axial clearance. Detection of axial clearance, the axis moved to an extreme position, and then measured with a feeler or dial indicator shaft runout from one extreme position to another extreme position that the axial clearance. 
 When the sliding NSK Bearings clearance of non-compliance, should be adjusted. Split bearings are often used shims to adjust the radial clearance (tip clearance). 

 The so-called cleanliness test is separated by means of the bearing impurities and test method for determination of the degree of pollution, current Cleanliness detection methods have the following three categories: Quality Law, microscope counting method, automatic particle counting method. 
 A: the quality of law. 
 JB / T ⒛ 50-2005 standards set by the State within the first SKF bearing impurities cleaning into the cleaning solution after cleaning fluid filtration, dried, weighed to calculate the quality of the impurity particles. 

 II: microscopy. 
 Similar to the previous step of this method and quality of law, different cleaning fluid filtering, the direct use of the size and number of impurity particles in the microscope observation membrane. But also according to the shape of the impurities, to determine the chemical composition and content of impurities. This method is most suitable for the determination of the cleanliness of precision bearings.

 : Automatic particle counting method. 
 Automatic particle calculations and Quality Act, microscopy, it is the use of the theory of the photoelectric principle, to directly determine the number and size of impurity particles. The accuracy of this method is relatively high, generally applicable to high bearing on cleanliness requirements.
