Type - Regular maintenance is essential for the longevity and optimal performance of spark plugs. Over time, carbon and other deposits can build up on the electrodes, reducing the spark's intensity and potentially causing misfires. To prevent this, it is recommended to replace spark plugs at regular intervals, typically every 30,000 to 100,000 miles, depending on the make and model of your car.
- Valve cover gasket bolts come in various sizes and grades, each designed to withstand the specific torque requirements of different engines. They are usually made from high-strength steel or alloy, capable of withstanding the intense heat and pressure within the engine compartment. The correct tightening sequence and torque specification are essential to ensure these bolts don't loosen over time, causing leaks or even damaging the threads in the cylinder head.
Oil seals come in various shapes to fit the machine or substance for sealing.
For this reason, when designing a machine, it is important to select the oil seal that is right for that machine.
Next time, we will explain the key points to consider when selecting your oil seal.
Figure 4 shows the features of a JTEKT oil seal.
The outer part of an oil seal is made of metal or rubber, depending on the intended application. Metal-cased seals are a cost-effective option used when the housing bore is made of the same material, allowing for equal expansion and contraction of the materials during use. Rubber-cased oil seals provide a tight fit and are commonly used when metal-cased seals have the potential to fail. They are corrosion-resistant and capable of withstanding extreme temperatures and pressures.

Oil seals are used in any industrial application that has a rotating or moving part assembly. This includes:
Above, are all the components of an oil seal and all its naming conventions. Beyond selecting the correct size, the three primary selection criteria are Material, Lip, and Case. If you have an oil seal you’d like custom designed and made, send us your specifications through our Oil Seal Design Form.
