Bearing on itself sealed by structure of forms of to divided if, can is divided into contact type of sealed effect, and for contact type and can is divided into radial sealed Dutch axis to sealed of situation is as of effect, according to sealed ring of constructed is divided into single lip sealed of effect, and to appeared this aspects effect if, in sealed aspects of effect is not as, and reflected out of effect is has must of meaning, so to better of to reflected out such of situation if, Cylindrical roller bearings seal information to through more technical introduction to begin.
1. Guide accuracy: guiding accuracy refers to the motion components along the guide rail when its trajectory accuracy. Main factors influencing the orientation precision of geometric precision of the Guide bearing surface type of structure, guide rails, guide contact accuracy, surface roughness, guides and supports the stiffness, the rigidity of oil film thickness and film guide, and guides and supports thermal deformation. Geometric precision linear motion guide including: linearity of the vertical plane and horizontal plane; of parallelism between two rails. Guide on geometric accuracy with rail full length error or errors on the unit length.
2. stiffness: Guide to resist force and deformation capacity. Deformation affects the component between the relative position and orientation accuracy, which is particularly important for precision machinery and instruments. Includes Rails ontology guide contact deformation of rail deformation, both of which should be taken into account.
3. precision retaining ability: precision retaining ability is to guide rail's ability to retain their original geometric precision while working. Precision retaining ability depends primarily on the rails of the Rails wear very good dimensional stability. Wear resistance materials match with the Guide, mechanics, machining precision, lubrication and protection devices performance factors, addition, residual stress within the rail and its support will also affect the precision of the guide rail retention.
To in this aspects supporting bearing if attached sealed device can effective to prevent has outside foreign body of invasion, but in this sealed device will will increases institutions of axis to size of forms, and from these aspects to cylindrical roll child bearing using has Dutch installed maintenance brings inconvenience of effect, while which sealed performance also to was axis neck Dutch Shell body match parts of processing precision and the shaped bit tolerance of effect effect. And with sealed bearings can have a good environment for seal lubrication effect, and solved the problem of supporting parts, but also eliminates the complex effects of lubrication system, so compact, sealed when demanding parts, we recommend using a sealing effect.
Bearing performance of relevance in this context is also from the sealed structure to reflect the effect, while in other areas they are better able to reflect this effect, by the same token, reflected on the significance of the effects can change the effect of this change was better, this is the meaning of an expression.
