Size: Males and females of adulthood differ significantly in size. Adult females weigh up to 180 kg and are roughly 180 cm long, while adult males typically weigh up to 300 kg and are about 250 cm long (but they have been reported to exceed 360 kg and 300 cm).
The TCV type is an oil seal that can withstand pressure and has more robust lips. Generally small-diameter, medium-pressure rotating shafts under pressure are utilized. Oil Seal for Rotary Shaft of a Different Type.
The exterior surface of the liner is used to measure the seal size. Which seal size is needed depends on the liner and shaft diameter. A total diameter of 170 millimeters including the shaft and liner is indicated by a STA 170, for instance.
Anywhere shafts rotate and bearings need to be lubricated, oil seals are utilized. The Timken line of O-Ring Seal Kits, which comes in inch and metric sizes, provides the coverage required for the majority of common applications.

Usually called "semi-dual" lip types, they keep debris and dust out of the main lip region. Available in Silicone (VMQ), Viton® (FKM/FPM), Nitrile (NBR), and Polyacrylic (ACM) sizes in both inch and metric units.
The peripheral airways of deep-diving whales and seals are strengthened, which is thought to allow the lungs to collapse during the descent. This type of collapse in the deep-diving Weddell seal has been seen radiographically and verified by blood nitrogen studies.
Available sizes and ranges. To satisfy the needs of each application, the bulk of All Seals' PTFE radial shaft seals are custom-made. Nonetheless, there exist specific standard sizes falling between the intervals of around 6 to 200 mm (0.250 to 8 in.) for shaft diameter and roughly 16 to 230 mm (0.630 to 9 in.) for shaft diameter.
The seal of BaikalAt 1.1–1.4 meters (3.6–4.6 feet) in length and 50–130 kilograms (110–290 pounds), the Baikal seal (Phoca sibirica) of Lake Baikal in Siberia, Russia, is the smallest; however, some female fur seals weigh less. The largest is the male coastal California elephant seal (genus Mirounga leonina), which includes:
The depths where all this delicious seafood lurks during the day are inaccessible to most animals that breathe air. Elephant seals' ability to dive deep allows them to elude huge predators that could hunt them down at the surface and to leave behind rivals who might outcompete them there.
Does thickness of oil seal matter? Different seal widths do not provide any sealing benefit as long as the seal matches the shaft and bore diameters adequately.
