Lay out the pieces of the new gasket on clean newspaper, and note how the joints fit.
Leather
Recommended for abrasive applications
Good running properties, due to the impregnated seal lip
Can be used on shafts which have a surface roughness outside the range for rubber seals
Not suitable for water
Figure 7: Oil seals for steel production equipment (rolling mill)
Regular inspection and maintenance of wheel hub oil seals and steering oil seals are essential to identify signs of wear, damage, or leakage. Proper lubrication and adherence to recommended service intervals can help extend the lifespan of these seals. When replacement is necessary, selecting the correct seal type and ensuring proper installation are critical to maintaining the integrity and performance of the vehicle's wheel hubs and steering mechanisms.
Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.
In conclusion, shaft oil seals are essential components in machinery and equipment that help to prevent leaks, protect critical components, and ensure smooth operation. Their importance cannot be overstated, and proper selection, installation, and maintenance are key to maximizing their effectiveness and prolonging their lifespan. With the right seals in place, machinery can operate efficiently and reliably, delivering optimal performance and productivity.
