Characteristics: the oil seal edge is a metal skeleton, inner plastic bag, a single lip, with spring, SB, SBB oil seal for high speed sealing in harsh environment, need to assemble applications, SB, SBB oil seal has the advantages of good rigidity, easy installation, safe use, accurate positioning, high coaxiality, good heat conduction and heat radiation the characteristics of SB, SBB, seal is on the seal skeleton of centerless grinding, improve the concentricity of the seal after the outer and the inner wheel, to prevent oil leakage, especially is widely used in the use of harsh conditions or requirements of high precision of place.
Material: NBR rubber, NBR, fluorine rubber, FKM
Pressure: 0.3kgf/cm2
Temperature: -40 ~ 120 DEG C (NBR)
-20℃～250℃（FKM）
Speed: 25m/s (NBR)
38m/s ( FKM )
Installation: SB, SBB oil seal specifications are relatively large, in the assembly should pay attention to the vertical assembly in the slot. Therefore, higher machining accuracy of mounting holes is required.
