Choosing Quality Spark Plug Wires and New Spark Plugs

JTEKT provides special seals for use in a wide variety of machines and applications.
Table 5 lists the major special seals, their shapes, and their features.

Oil seal vs. mechanical seal is not always an easy decision. In some cases, one is the obvious choice because you are replacing a worn out seal with the same type. But in other situations, either type would work and the question is which will enhance productivity the most. At Abbey Seals, we have ample experience with a full range of seal types. We are happy to discuss the specifics of your application and advise you on the optimum type of seal for your equipment. The decision between a rotary shaft or oil seal vs. mechanical seal involves many factors, and we are here to help you make the best choice for your specific needs.

In recent research, MWCNTs and carbon black were mixed with the butadiene/natural rubber to form a hybrid composite which gives very strong filler links by partial replacement of carbon black based on the m₁:m₂:X (m₁—MWCNT; m₂—reduction amount of carbon black; X-varies from 1 to 6) [40,64]. An internal blending mixer and two-roll milling were used to formulate the composites. The synergistic effect plays a major role in improving the abrasion resistance property due to the partial replacement of carbon black by adding MWCNTs in different ratios. The optimal ratio value of MWCNTs is 5 (parts per hundred of rubber) and 27.5 (parts per hundred of rubber) for carbon black with better resistant to abrasion compared to the matrix material [64]. The vulcanized hybrid composite material reinforced with MWCNT/carbon black at the ratio of 1:1 shows better mechanical properties, curing characteristics, and thermal conductivity. This shows a better tyre thread with an improved endurance life, less curing time, and improved thermal conductivity [42,64]. Fig. 4.4 shows the SEM and TEM images of uncured and cured rubber and Figs. 4.5 and 4.6 show the application of rubber nanocomposites in a tyre application.
