Floating seal Introduction：

Floating seal consist of two same metal steel rings and two same rubber rings. Its working principle is a pair of metal rings supported by a pair of rubber rings to form a closed space with the cavity (but not in with the shaft). When running, the after-grinding seal surface of the two metal rings act in close coordination and sliding relatively. On the one hand, to ensure good operation, on the other hand, to cut off the outside dust, water, rocks, gravel etc. effectively, and protect the inside grease or oil from leaking. The product types include DO style, DF style and XY style.

Floating Seal Advantage:

l Reliable design, simple installation

l Low cost, high efficiency

l Longer working lifetime

l Automatically compensate eccentricity of the shaft

l Self-repair lapping sealing surface

l Cut off the outside dust, water, rocks, gravel etc. effectively, and protect the inside grease or oil from leaking

Applicable Industries:

Floating seal is used widely, usually is used in the slow speed operatio

and the place required high lubrication reliability and long working

lifetime, such as mining machinery, agricultural machinery, construction

machinery, heavy truck, coal cutter,tunneling machine, scraper conveyor and cultivated land machine,etc.

Material:

The material of metal ring is usually alloy cast iron and forged steel, hardness is 58-72 HRC. The material of rubber ring is commonly NBR, we also provide other rubber materials such as HNBR, VMQ,FKM.

Installation Instructions:

u Unless open the package of floating seal products before using and installation, to prevent the product surface from rusting, polluting or bruising on sealing surface, it is strictly prohibited to put seal face downwards.

u Before the installation thoroughly clean the installation groove and sealing, remove all the residue, it is suggested to use volatile solution, such as alcohol. Check and ensure that there is no burr in the installation groove.

u Check the position of the rubber ring, must no twist, with the joint an>position of rubber ring as a reference.

u Using a special installation tool to put half of floating seal into the entrance of the installation groove, and then uniform and steady pressure into the cavity groove. It is forbidden to use any oil or grease to increase lubrication for making the installation easier. It can be sprayed with a small amount of alcohol to assist installation if necessary.

u After installing half of floating seal into groove, check the position of the rubber ring, and make sure the rubber ring is no twist or asymmetry. Sealing face must be parallel to the plane of the cavity, and the maximum deviation is 1 mm.

u Check to confirm all the above is no problem, then wipe the working sealing face of floating seal (sealing surface oil belongs to rust-proof oil rather than lubricating oil), and remove all the residue, it is suggested to use volatile solution to wipe, such as alcohol and acetone, and blow using the cold wind gun. After dry and clean, daub a thin layer lubricating oil on the metal seal working surface.

u Install the other half set of floating seal into the corresponding cavity groove, and match the another half set after wiping clean the sealing surface, and adjust the installation gap to make the working pressure meet the requirements of the operating.
