- Diamond Bits These are designed for drilling through hard rock and are often employed in geological explorations.
- Maintaining spark plugs is an essential aspect of routine auto care. Over time, deposits can build up around the electrodes, inhibiting their ability to generate a strong spark. Regular checks and replacements when necessary help maintain optimal engine performance and reduce the risk of unplanned breakdowns.
Various materials with unique properties are utilised in the construction of rotary shaft seals, allowing manufacturers to tailor the sealing solution to specific industry requirements and ensure optimal performance.
- 2. **Resisting Pressure** Oil seals are subjected to internal pressures that can cause them to fail if not properly dimensioned. Understanding the seal's dimensions helps ensure it can withstand these pressures without compromising its integrity.

NNK belongs to NOK-CN factory, we have more than 150 employees and strong delivery capacity. Our technicians are experienced, we have been committed to the sealing industry for decades, and have independent research and development capabilities. Our metal shells are produced by ourselves, and the quality is guaranteed. Our rubbers are all imported materials, and each product is strictly tested.If you need please contact us.
Regular inspection and maintenance of 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 oil seals. When replacement is necessary, selecting the correct seal type and ensuring proper installation are critical to maintaining the integrity and performance of the equipment.

Pressure - Many oil seals can only withstand low-pressure applications, so understanding the compression set of your components is key.
To do this, turn the engine with a socket on the crankshaft pulley bolt until the rotor arm is pointing to the plug contact of the timing cylinder (usually No. 1, check in the car service manual), and the timing marks on or behind the pulley show exactly top dead centre ( TDC ).
