Oil Seals for Industrial Appications - Fitco Engineers Pvt Ltd

Radial shaft seals used for all industrial sectors. They are particularly suitable for split and/or light alloy housings with increased thermal expansion and/or poor surface quality of the housing bore. Advantageous for static sealing in housing against low viscosity liquid or gaseous media. The secondary lip of  DL-TC seals keeps dirt away from the sealing lip.

Whenever a shaft rotates, it needs a bearing arrangement for smooth and effective operation. Wherever there is a bearing, you will always find a seal helping it to reach its maximum service life and reliability. The most common types of seals, used in bearing arrangements, are radial shaft seals, in small diameter sizes (outside diameter up to 200 mm / 8 in) for general industrial requirements and the large diameter seals, LDS (larger than 200 mm / 8 in outside diameter), specially designed for heavy industry and large bearing arrangements. In general terms, a radial shaft seal is a barrier with four main functions:

Oil Seals - Supplier & Distributor of Oil Seals - FITCO

Rotary seals and Shaft Seals are used in components with oscillating or rotating parts to keep lubrication fluids in while preventing ingress of mud and water. Oil and grease seals have a flexible lip that rubs against a shaft or housing to prevent the leakage or ingress of fluids and dirt. For proper installation, the seal lip should point towards the medium being contained. Sealing ring is reinforced with a metal ring and equipped with a tensioning spring. In some types, however, an oil seal without a spring or metal ring is used. Oil Seals find wide application in various sectors of the automobile industry. Increasingly being used as original equipment by leading manufacturers of cars, commercial vehicles and tractors in India. These come in a wide range of standard and non standard designs. Our durable oil seals interchange with all major brands. Common stocked elastomers include NBR, FKM, EPDM, VQM, ACM and HNBR When looking for industrial oil seals, Fitco Engineers Pvt Ltd is your s…

O-Rings Design Guidelines, Specifications - FITCO

O-Rings are one-piece molded objects made from elastometric seal with a circular cross-section. They are used to prevent fluid movement between mechanical parts by maintaining contact with the inner and outer walls enclosing the ring. The resiliency of the rubber provides a zero-pressure seal. When pressure is applied, the fluid forces the O-Rings across the groove and causes more deformation. This leads to the ring flow up to the fluid passage and seal it against leakage. O-Rings are an example of self-energize seals, meaning they relay pressure inside the container (or pipe) to give them the pressure necessary to form the seal. O-Rings are inserted into cavities called glands, and they are used in either axial or radial seal designs. An O-Ring is described by its inner diameter, its outer diameter, its material hardness 
(or durometer) and its material composition. 

Dimensions of O-Rings are given in ANSI/SAE AS568A. A seven-digit number is assigned to each ring to designate the ring …

Types of Oil Seal Materials / Material Selection Guide for Oil Seals - FITCO

Which is the Best Material for Your Oil Seal? 

Application:  Radial shaft seals, also known as lip seals, are used to seal rotary elements, such as a shaft or rotating bore. Rotary shaft seals play a key role in extending the operating life of bearing systems and reducing the overall costs of maintaining these systems. The primary function of a rotary shaft seal is to retain bearing system lubricants therefore allowing the bearings to operate in optimal levels of lubrication. The secondary function of a rotary shaft seal is to exclude contaminants from the system, contaminants that can both damage bearings and break down the effectiveness of lubricants. 
USP:  The seal construction will consist of a sprung main sealing lip which has a point contact with the shaft. The point contact is formed by two angles, with the air side angle usually less than the oil side angle. “Depending on the seal type these two angles are varied to create a “pressure distribution” at the seal contact point whic…
