Further, the roller is made of high molecular material.
Further, filled in the gap between the end cap seal bar, bearing block sealing strip, annular seal space, seal
Lubricating oil.
Compared with prior art, the sealing structure of labyrinth type high-polymer supporting roller provided by the utility model is unusual, passes
The bearing block of system is set on the inside of bearing, and the bearing block of the utility model is set on the outside of bearing, that is, specifically
When assembling, installation, first bearing is installed in place, is then again installed in place bearing block, for whole carrying roller, bearing block
Positioned at the outside of bearing, one layer of sealing, protection can be played the role of, and bearing block can coordinate with end cap, form labyrinth
Formula sealing structure, in the case where reducing component, ensures or improves sealing function, without being separately provided a sealing again
Part, overall structure is simplified, component is simplified, sealing effect is more preferable.Pass through end cap seal bar and bearing block between end cap and bearing block
Sealing strip overlaps interspersed, formation labyrinth sealing, and annular seal space is provided with end cap, and seal is provided with annular seal space,
Sealing effect is further increased, with reference to end cap and bearing block structure, annular seal space and seal configuration.Bearing block position, forms
