Seals range fills all the gaps
| Blue Diamond, specialists in the design and supply of oil seals,
holds a vast stock which includes specials for heavy duty use, for
high speed rotary applications, for high pressure linear
motion systems, and seals enjoying the added value of proprietary
non stick surface treatments. Heavy duty seals not only retain lubricants
inside a mechanism: they also keep water, dirt and other contaminants
out - vital in heavy construction and agricultural machinery, when the
air can be thick with concrete dust or flying mud. PTFE lip seals have
a narrow band of fluoroelastomer bonded inside a conventional Viton ™
body.
In operation a minuscule amount of PTFE is transferred to the
surface of the shaft, filling microscopic pits and establishing a
perfect lubricant
film. |

The result is efficient dry running and long life, even at speeds
up to 20,000 rpm.
High pressure linear motion seals (withstanding oil at 100 bar)
look like ordinary oil seals, but have a stainless steel insert within
the nitrile body to hold the seal in place on a plain shaft or
cylinder with just a tight interference fit.
Blue Diamond's SSHT and SBBT surface treatments of O rings and rotary
shaft seals ensure impressively low start-up and running friction.
They also improve the ageing properties of the rubber, inhibiting
deterioration in storage or when components are operated spasmodically
or remain dormant for long periods.
