O-ring Sealing Prince

O-rings are bi-directional seals, cirar in shape and cro section. O-rings are generallymade of an elastomeric material, but may be made of other materials such as PTFE ormetal. An O-ring seals through the deformation of the seal material by installation and media preure to close off the gap between mating components. Higher system preures can cause deformation through the gap, known as extrusion, resulting in seal fai. Choosing a harder seal material or installing back-up rings to support the O-ring may alleviate this problem.

Method of operation

O-Rings are double-acting sealinements. The inital ,which acts in aradialora xial direction depending on the installation, gives the O-Ring its initial sealing capability.These forces are rimposed by the system preure to create the total sealing force which increases as the systeme preure increases (Figure 2).Under preure, the O-Ring behaves in asimilar way to a with high surface tension. The preure is nsmitted uniformly to all directions.

EPDM (Ethylene-Propylene-Diene Monomer O-Ring):

EPDM O-ring in auto parts, hygiene supplies, equipment, marine equipment, petroleum equipment, telecommunications equipment, instrumentation, machinery and other industrial fields are widely used.Use temperature range: -50 to 150 °C

Application

The O-Ring is used predominantly for static sealing applications:- As aradial static seal, e.g. for bushings, covers, s, cylinders- As an axial static seal, e.g. for flanges, plates, caps.O-Rings in dynamic applications are recommended only for moderate service conditions.They are limited by the speed and the preure against which they are to seal:- Forlow duty sealing of reciprocatingpistons, rods, plungers, etc.- For sealing of slowlypivoting,r otating or ral movements on shafts, ndles,rotary nsmiion leadthroughs, etc.

FAQ

1. Why do the bearings I receive have shaking?

The clearance of the bearing is related to the play.The default is the standard C0 clearance, which is usually 3-18um.The corresponding prince is shown in the figure below.If you don't need to shake, please choose C2 small clearance bearing,If you have any questions, please contact us before purchasing.

2. What is the accuracy of ABEC-1?

ABEC is the American ANSI standard.The corresponding German DIN standard and international ISO standard are as follows:
