 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).

 SKF bearing conditions of use and environmental conditions correctly grasp the use of bearings in machinery parts and conditions of use and environmental conditions is the appropriate choice of bearing the premise. Whom need to obtain data and information on the following aspects: 
 (1) the function and structure of the mechanical devices 
 (2) bearing the use of parts 
 (3) bearing load (size, direction) 
 (4) The rotation speed 
 (5) vibration, shock

 (6) bearing temperature (ambient temperature, temperature) 
 (7) is usually the choice of the surrounding atmosphere (corrosion, clean, lubrication) bearing configuration, the axis is based on two bearings in the radial and axial support side of the bearing is called the fixed side bearings, radial and axial two loads, since the relative axial displacement between the role of the fixed shaft and the bearing housing. The other side as the liberal side, only radial loads, axial relative movement, in order to resolve the axis stretching part of the question due to temperature changes and installation of bearing interval error. For the fixed side of the bearing, the need to select the available rolling surface in the axial movement (such as cylindrical roller bearing) or move to the assembly surface (eg, radial ball bearings) bearings. In a relatively short shaft, the fixed side free side of the little other cases, only one-way fixed axial movement bearings (angular contact ball bearings). Bearing type selection select bearing type, is essential to fully grasp the bearing conditions of use.
