Feature: 1. Made of high‑quality FKM materials, high temperature resistance, compression resistance, well adapted to different temperatures. 2. High‑quality spring prevents sand, dust, moisture, etc. from entering the bearing from outside, and the lubricant in the bearing is leaking, which has a better sealing effect. 3. Strictly control the size and the wiring is exquisite, not only the appearance is exquisite, but also a better sealing effect can be achieved. 4. Applicable to industries such as aviation, vehicles, motorcycles, railways, ships, household appliances, and engineering equipment. 5. Suitable for rotational motion and reciprocating motion sealing, installed in various types of engines, gearboxes, axles, ships, cylinders, etc. Specification: Item Type: Oil Seals Material: FKM Type: TC Sizes: Approx. 65 x 90 x 12mm / 2.6 x 3.5 x 0.5in Working Temperature: -40℃~125℃ Purpose: Mainly Prevent the Penetration of the Sealed Medium (Gas, Liquid) and Foreign Matter from Entering the Body. Package List: 2 x Oil Seals Note: 1. Shaft rotation speed Due to design and structure reasons, high‑speed shafts should use high‑speed oil seals, and low‑speed shafts should use low‑speed oil seals. Low‑speed oil seals cannot be used on high‑speed shafts, and can't reverse.2. When the ambient temperature is high, polyacrylate or silicone, fluorine, or silicone fluorine rubber should be used. And should try to reduce the oil temperature in the fuel tank. When the operating temperature is too low, cold‑resistant rubber should be used.3. Oil seals with normal pressure have poor pressure bearing capacity, and the oil seals will be deformed when the pressure is too high. Under conditions of excessive pressure, pressure bearing rings or reinforced pressure oil seals should be used.4. If the eccentricity of the installation oil seals and the shaft are too large when the eccentricity is too large, the sealing performance will become worse, especially when the shaft speed is high. If the eccentricity is too large, an oil seals with a "W"‑shaped section can be used.5. The appearance finish of the shaft directly affects the service life of the oil seals, that is, the higher the finish of the shaft, the longer the service life of the oil seals.6. Note that there should be a certain amount of lubricating oil on the lip of the oil seals.7. Pay special attention to prevent dust from entering the oil seals.
