The primary function of the ceiling grid main tee is to provide structural integrity. By distributing the weight of the ceiling tiles evenly, the main tee minimizes the risk of sagging or collapse. In addition, the grid system can accommodate the installation of other essential building elements, such as lighting fixtures, air conditioning vents, and fire alarm systems. This versatility makes suspended ceilings a preferred choice in commercial spaces, schools, and hospitals where various services must coexist seamlessly.

One of the defining features of mineral fiber ceilings is their superior acoustic performance. The porous structure of mineral fiber tiles allows for effective sound absorption, making them an ideal choice for spaces where noise control is paramount. Open-plan offices, schools, and auditoriums benefit significantly from the sound-dampening properties of these ceilings. By reducing echo and noise pollution, mineral fiber ceilings contribute to a more comfortable and productive environment.

Custom PTFE Oil Seals and Other Seals for Your Application
The allowable total eccentricity is the maximum total eccentricity at which the sealing edge can accommodate shaft rotation and retain adequate sealing performance. The oil seal's allowable total eccentricity is affected by the design of the oil seal, the accuracy of the shaft, and the operating conditions.

Whether the seal is a standard product or a custom solution, our engineers ensure that the seal is specified for your application.
Oil seals, which are also known as rotary shaft seals, fluid seals or grease seals, play an important role in closing down the gaps between moving and stationary elements of mechanical equipment.
Oil seals are found in a wide range of applications, in virtually every industrial sector. It is essential to select the correct oil seal so that the application in which it is used can run efficiently, free of leaks or other issues. In this blog, we explain which factors you should pay attention to when selecting the best oil seal for your application.

What are Oil Seals and the different types?

(4) The degree of eccentricity on the installation If the eccentricity of the oil seal and the shaft is too large, the sealing performance will be deteriorated, especially when the shaft speed is high. If the eccentricity is too large, a W-shaped oil seal can be used.
Runouts need to be minimized. The most common causes of the center of rotation movement are shaft whip and bearing wobble. The issue is even worse when there’s misalignment. Contrary to widespread assumption and practice, misalignment cannot be corrected or made up for by using flexible couplings.

Constructional Aspects of an Oil Seal:

There is a British Standard laid down for the control of synthetic rubbers. BS 3574 (1989) helps to determine shelf life – for instance, Nitrile (NBR) and Polyacrylic (ACM) are Group ‘B’ rubbers and have a 7-year life, whilst Silicone (VMQ) and Fluoroelastomers (Viton®) are Group ‘C’ rubbers and have a 10-year shelf life. PTFE and Leather do not come into this category but like the others should be kept in the original packing for as long as possible away from direct light, dust, and humidity. Ozone, which can also be produced by battery-driven forklift trucks has a very bad effect on synthetic rubbers. Finally, protect the sealing lip – DO NOT hang the seals on nails, wire etc.


Standard 3760/3761
The simplest way is to know either the preferred manufacturers part number, the overall sizes of shaft diameter, housing diameter and bore depth, or use our brochure to establish the M Barnwell Services ordering reference. Many of the old traditional names of seal manufacturers have either changed or disappeared in this age of “acquisitions”. If no longer available, we will advise you and offer a suitable alternative seal, from stock whenever possible. If your concern is getting the right seals for the job, you will need to know something about the application as well as the overall sizes. If you have any doubts – contact us, we will help in your seal selection.
The group of oil seals used in dynamic applications include radial shaft seals that seal a rotating shaft around its circumference. They are also known as lip seals, but in this blog we will use the term oil seals.
Various materials with unique properties are utilised in the construction of rotary shaft seals, allowing manufacturers to tailor the sealing solution to specific industry requirements and ensure optimal performance.
