rotary shaft seals -
The sealing effect is achieved by pre-loading the sealing lip so that its inner diameter is slightly smaller than the shaft diameter.The Garter strip spring ensures that the shaft is subjected to constant force, squishing the edges to the defined width.The main function of the rotary shaft seal is to retain the bearing lubricant, and secondly, to improve the performance and life of the bearing by minimizing dirt, resulting in damage to the bearing and other components and premature failure of oil and water to enter.
Rotary shaft seals are designed to seal fluid, oil, grease, oil mist or other media on rotating equipment, including rotating or swinging shafts, rods or holes.In addition, there are rotating seals specially designed for applications such as dry operation, high pressure, low friction and low energy consumption, high temperature, high surface speed, etc. The shaft is not neutral and corrosive media.
Rotarys haft seals are used in components with oscillating or rotating components to keep the lubricating fluid in place while preventing the entry of mud and water.A wide range of rotary shaft seals for rotary applications are available on the market;From the traditional one-or two-port elastic structure to the design based on the four fluorine or the combination of the two, these are all available.There are many different materials to choose from for the rotating shaft seals.
These are elastic-based lip parts, including acrylic acid, fluorine compounds, carbonated acrylic acid, hydrogenated acrylic acid, Ethylene Propylene, acrylic acid, silicone and neoprene.Rotating seals have a wide range of different enclosures, most commonly including carbon steel and stainless steel.Other housing materials include aluminum and galvanized cold-rolled steel according to application standards.
Only one pneumatic seal is required for rotary applications.This seal is considered single acting because it can be sealed in one axial direction when the application moves.On the other hand, the application of reciprocating motion requires two pneumatic or double acting seals.
In this case, a seal is required for each direction.The double-acting pneumatic is more complicated than the single-acting pneumatic.Pneumatic seals can be single-acting or double-acting.
Single action pneumatic is only used in one axial direction.The rotary axis and pneumatic can be made from a variety of materials such as polyurethane, vinyl, fluorine rubber, silicone, ethylene-propylene rubber and some four fluorine rubber.A composite seal consisting of two or three different materials.
Therefore, pneumatic seals are often found in products where many parts require one seal.Darcoid\'s product selection is the widest range of products in the industry for rotary axis, pneumatic and hydraulic sealing systems
