Rolling Silica gel also has some drawbacks mainly: 1. Rolling Silica gel to bear the load capacity than the same volume of sliding Silica gel is much smaller so scroll Silica gel radial size large. So bear a large load dems of the occasion radial small size compact structure required occasions such as crankshaft Silica gel) multisliding Silica gel 2. Rolling Silica gel vibration noise is higher especially late particularly notable in the use therefe deming precision not Xuyou Zhen moving occasion rolling Silica gel difficult to competent generally used in the sliding Silica gel the effect of me good 3. Rolling Silica gel on the metal shavings other feign bodies are particularly sensitive Silica gel Once inside the feign body will produce intermittent to high vibration noise will lead to early damage. In addition the rolling Silica gel due to impurities such as metal clips are also prone to the possibility of early damage. Even if the damage does not occur early rolling Silica gel life there are certain limits. In sht rolling Silica gel life than the sliding Silica gel shter.
