Description:This flaoting oil seal 130-27-00010 compatible for Bulldozer KOMATSU D40A etc.The floating oil seal is composed of two identical

metal rings and two rubber rings. Its working principle is that a pair of rubber rings form a closed space with the cavity under the support of the

metal ring (but not in contact with the shaft). The metal ring is rotating. The two grinded surfaces of the machine are closely matched and slide

relatively, on the one hand to ensure good operation, on the other hand, to effectively seal off external dust, water, sludge, etc., to protect the

internal grease from leaking.

Working Principle of Floating Oil Seal

The structure of the floating oil seal is generally composed of a pair of wear-resistant metal rings-floating seal ring

It is composed of a pair of rubber rings and is assembled in a special sealed cavity-a floating seal seat.

The floating seal ring is the main component of the dynamic seal, which is opposed to each other and rotates and rubs against each other.

Between the rubber ring assembly and the back of the floating seal ring and the floating seal seat, the floating seal ring is accurately positioned in

the floating seal seat. The rubber ring is not only an auxiliary static sealing element, but also produces axial and radial forces on the floating seal

ring. The radial force plays the role of transmitting torque to the floating seal ring, and the axial force provides the necessary sealing

compensation force to the floating seal ring. Due to its large elastic compensation range, it can maintain the The effective bonding of the sealing

surface of the metal ring achieves the effect of floating seal
