For decades the radial lip seal is the most important building block in the design of the rotating shaft sealing system. ESP International is your source for cost-effective, high-quality radial shaft seals. Our strength lies in our ability to assist with design at the front end – whether it is a sealing application or simple material selection assistance. Referring now to FIGS. The fluid pressure which can be sealed when using a radial lip seal is typically low, e.g. Get contact details and address| ID: 21243473291 The Netherlands. Worn seals can cause leakage, plugged breathers or damaged bearings that allow radial motion. (Figure 1) Nieuwland Parc 306 ESP International is your source for cost-effective, high-quality radial shaft seals. It is normally pressed against the counterface surface of the shaft, with a defined radial load, by a garter spring. of radial lip seal applications across the industrial spectrum — including marine duties. 7) Radial Wall 8) Seal Outer Diameter 9) Housing Bore Diameter 10) Spring Position (R-Value) 11) Spring Groove 12) Garter Spring 13) Heel Section : 14) Flex Section 15) Spring Retainer Lip 16) Inside Lip Angle 17) Toe Face 18) Auxiliary (Dust) Lip 19) Rib (Helix) 20) Contact Point 21) Inside Lip Surface 22) Spring Set Lip Diameter This way a suitable sealing solution is granted. The seal lip I.D. These lip seals are clamped in bronze housing parts and run on a corrosion resistant liner. Read about company. This film is necessary to prevent damage to the lip caused by mechanical stresses and heat that is generated at the lip–shaft interface. Need a custom profile? Penyekat atau perapatan (sealing) berdasarkan perbedaan ukuran elemen seal dan diameter luar shaft merupakan dasar prinsip sealing, juga ditambahkan spring dibagian belakang lip seal untuk membantu kerapatan lip seal pada shaft. The variations of coefficient of friction in a radial lip seal contact can be attributed to three phenomena: The details of their calculation are described (Ref. After assembly of the lip seal on to the liner the elastomeric lip seal is in a pre-stressed state on the liner surface due to the difference in outer liner diameter and inner lip seal diameter and due to the garter spring. They are used to seal lubrication in and/or contamination out, or to separate dissimilar media. Lips are an integral part of the design of wiper scraper seals, so these can technically be described as lip seals. A radial lip seal generally consists of an elastomeric lip with an asymmetric tip geometry. Radial Oil Seals About Radial Oil Seals Rotary seals operate between two surfaces in relative motion with each other. a few bars at maximum. If you continue to use this site we will assume that you are happy with it. This force is a very important parameter for developing a continious oil film layer between the shaft and lip. Trelleborg's portfolio of rotary seals includes the commonly known radial oil seal, rotary shaft seals, radial and axial lip seals, double-acting O-Ring energized Polytetrafluoroethylene (PTFE) rotary seals for shaft and bore, rubber V-Rings, mechanical face seals / heavy duty seals and many more. For details of these, please refer to pages 11‑13. from entering the equipment on one hand and the prevention of leakage of fluids from inside the equipment to the environment on the other hand. This provides a tight spring between the membrane and the lip seal. A radial lip seal generally consists of an elastomeric lip with an asymmetric tip geometry. In most cases multiple radial lip seals are applied in various arrangements to provide a reliable and cost effective system which fits the application best. We carry patents on several innovative designs for radial lip high fluid temperature seals, high-pressure seals, low-torque and long-life seals – seals that keep contaminants out in harsh environments. The design is freely selectable and is determined on the basis of the application parameters.
