Advantages of Natural Rubber:
1.NR also has excellent resilience, insulation, water resistance,
plasticity and other characteristics, and after processing also has
oil resistance, acid resistance, alkali resistance, wear resistance
and other advantages;
2.Strong wear resistance, good shock absorption effect；
3.High elasticity, high tensile strength, excellent tear resistance
and electrical insulation resistance Good abrasion and drought
resistance, good processing, easy adhesion of other materials, It
is superior to most synthetic rubber in comprehensive performance；
Installation Method
(1) Recommended oil seal installation tools and methods
1. The installation of the oil seal can be flush with the front end
of the casing aperture, or it can be close to the low section of
the casing aperture.
2. The reference planes for installation and positioning should be
machined surfaces, and the unprocessed reference planes cannot be
used.
3. The outer diameter of the oil seal should be coated with a layer
of lubricant.
4, using hydraulic or pneumatic uniform pressure compression oil
seal.
Note: The matching surface of the oil package is flush with the
reference surface of the housing to ensure the verticality of the
shaft and the center of the shaft after the shaft is installed, so
that the oil seal lip becomes a line contact belt on the shaft
surface to achieve a good sealing effect.
(2) Installation without oil seal
1.Apply a layer of suitable lubricant when the outer diameter of
the oil seal is assembled
2. Tap the oil seal firmly and evenly.
3. Check that the oil package is flush with the reference surface
of the casing after it is inserted.
Check that the oil seal spring must not come off.
Oil Seal Application:
The Engine
The Wheel Hub
The Gear
Construction Machinery Industry, Injection Molding Machine
Industry, Metallurgical Industry, the Press Industry, Engine.
The Prerequisites of the Oil Seal on the Gathering Shaft:
1. The surface harshness of the shaft is as per the arrangements of
GB1801. The shaft surface in contact with the oil seal should be
ground to a surface harshness Ra0.2 ～ 0.63um and Rmax = 0.8 ~
2.5um.
2. The width resistance of the shaft will not surpass h11 as per
GB1801.
3. The chamfer width is as per GB13871-92.
4. Surface hardness: The material of the shaft is ideally carbon
steel and composite steel. The suggested hardness is HRC45 or
higher. At the point when the medium is filthy and has sullied
pollutions from an external perspective or the direct speed of the
shaft is ≥12m/s, the surface hardness of the shaft It should be
HRC50 ～ 60, and the profundity of extinguishing layer should be
≥0.3mm.
5. The shaft is chamfered at 30 degrees (greatest). There should be
no burrs, sharp corners, and winding handling blemishes on the
chamfer. The unpleasantness of the chamfered surface Ra ≦ 3.2um.
The warmth treated carbonized layer should be cleaned and
eliminated.
