1 the oil seal is a split structure with convenient installation, and the structure of the oil seal is sufficient to ensure the sealing of the structure;

2. The oil seal adopts imported finger spring and ensure the lip of the oil seal radial force moderate, uniform, does not appear rubber material of the Joule heating effect, accelerate the lip mouth aging cracking phenomenon. Thus, the sealing effect is guaranteed, and the service life of the seal is improved;

. as a high speed oil seal, the import of special wear-resistant materials, with very low friction coefficient (0.11) is 1 / 6 of the traditional rubber materials for the wire speed in case of 20m / s, of the spindle wear is reduced to the minimum.
