Seat belt, spherical bearings (the insert bearing with housing) is the combination of rolling bearings and bearing with a 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), square seat (F), Boss Square Block (FS), Boss Round Tower (FC), diamond-shaped seat (FL), annular seat (C), the slider Block ( T).

 2, seat belt, spherical ball bearings Self-aligning performance 
 (1), the normal aligning range up to 2, then oiled. 
 (2), if not consider lubrication, aligning range up to about 8. 
 (3), aligning scope for closures of the bearing should be controlled in a less 
 3, the seat belt of the routine use of spherical ball bearings temperature of about -15 to +100 within the bearings used in high temperature by a special process, and durable accessories and high temperature grease. If necessary, please specifically discuss. 
 4 LNSERTED ball bearings at the factory prior to loading the right amount of industrial lithium grease on the 2nd. In the supplement to the bearing grease must use similar lithium base grease to avoid grease deterioration. Should not supplement overdose. 
 5, with a spherical ball bearing installation and removal method: 
 A, installation with Block, spherical ball bearings: 
 a, the bearing into the gap of the seat installation; 
 b, bearing a slight rotation, insert a wooden stick around the installation gap move to transfer about 90 
 c, the stick out of the box. 
 Note: The stopper pin should be placed within the seat installation gap, to prevent rotation within the bearing outer ring is here. 
 B, demolition with the spherical ball bearings; 
 a, a wooden stick into the bearing bore 
 B, bearing around the installation gap move turn about 90 
 c, the bearing out of the seat installation gap. 
 C, spherical ball bearings, seat belt installation: 
 a, top wire fastening the bearing, the bearing sleeve to the shaft, it is set position, tighten the top wire axis fastening; 
 b, the use of the eccentric sleeve fastening the bearing, the bearing sleeve to the shaft, it is set position, the top wire first along axis direction tighten the eccentric sleeve and the shaft fastening 
 c, the use of the adapter sleeve fastening bearings, bearings and tight the condom onto the shaft, it is set to the adapter sleeve position, having a good tight nuts, lock washers claw bending into the nut fastening the tank to prevent loose. 

 D, Note 
 installation and removal the LNSERTED ball bearings, generally do not beat and violently hammering; 
 b, tighten the top wire fastening bearings, the force should not be too big too fast, so as not to damage the top wire or the deformation of the bearing inner ring; 
 c, the bearing has been filled on the 2nd Industrial Lithium Grease should avoid different types of oil mixed the whole deterioration, affecting the bearings. 

 UCFU200 (F90500) with a square seat top wire, spherical ball bearings 
 Description: generally installed on the sidewall of the mechanical structure is simple, easy to install, is the most widely used as a flange bearing.

 Product information: 
 Spherical ball bearings has a compact, sealed perfect, convenient loading and unloading, and automatically adjust the heart of the scope of the advantages of large Host the rack structure is simple and can be used molding steel punched or welded together. This will not only improve the machine performance and reduce costs, Therefore, it is a wide range of applications in the field of agricultural machinery, textile machinery, food processing machinery and conveyor systems and so on. 
 First, the structural features: 
 The spherical ball bearings based on the fastening device can be divided into three structures. With the top of the silk of spherical ball bearings rely on both the top wire axis fixed up, pure radial and impact loads are generally used for small occasions, poor axial load. The spherical ball shaft with adapter sleeve, the adapter sleeve nut to the shaft and bearing linked together, therefore, it can withstand greater axial load. The spherical ball bearings with eccentric by the eccentric sleeve screw shaft is fixed, and linked together with the bearing, therefore, it is the ability to withstand the axial load. 
 Second, with the dimensions: 
 The spherical ball bearing outer ring and bearing tolerances generally H7, J7 and K7 but also can be different depending on the occasion. Spherical ball bearing inner diameter of the "+" tolerance, shaft diameter tolerance select h7, h8, the h9. 
 Three installation methods: 
 The installation of the spherical ball bearings, bearing on the shaft, the first bearing is firmly fixed to the supporting surface, and then bearing secured to the shaft can. Bearing and shaft of the fastening method is: spherical ball bearings with eccentric eccentric condom in the bearing inner ring of the eccentric stage, along the axis direction of rotation tighten the eccentric sleeve, and then within the socket head cap screw wrench to tighten the eccentric put the set screws can be. 
 Fourth, lubrication: 
 Spherical ball bearings factory filled with the right amount of grease (I used a No. 2 lithium grease), poor working conditions, and bearing high speed or temperature above 70 ℃ on the bearings for added grease, but supplement the same with the original model must pay attention to when filling grease.
