When designing a sliding bearing, there are several critical factors that engineers must take into account to ensure optimal performance and longevity. Here are the key points to focus on: 1. **Oil Grooves and Oil Pads**: Proper placement of oil grooves and oil pads is essential for maintaining an effective lubrication system. These features help distribute the lubricant evenly across the bearing surface. 2. **Avoid Sharp Edges**: Sharp edges or corners can disrupt the oil film, leading to increased friction and potential wear. Rounded edges should be used wherever possible. 3. **Keep Oil Holes Clear**: It's crucial not to block the oil holes, as they are responsible for delivering lubricant to the critical areas of the bearing. 4. **Avoid Full Ring Oil Grooves**: A full ring oil groove in the middle of the bearing can cause uneven oil distribution and reduce the effectiveness of the lubrication system. 5. **Ensure Smooth Oil Film Entry**: The oil film should enter the bearing smoothly without any obstructions. This helps maintain a stable and consistent lubricating layer. 6. **Oil Inlet from Non-Load Area**: The oil should be introduced from the non-load-bearing area to prevent it from being squeezed out under pressure. 7. **Reliable Oil Supply**: The oil ring should be designed to provide a strong and consistent supply of lubricant to the bearing surfaces. 8. **Prevent Oil Dead Zones**: Avoid creating areas where oil cannot reach, as these can lead to localized overheating and premature failure.

European Style Door Locks

The motise lock is a special type of lock used in commercial safty industry and requires heavy duty and high frequency lock application. One of the advantages of the European Mortise Lock is that even the Mortise Lock is produced, the lock cylinder and the drive member or, door handle are produced by different manufactures, but the specifications are the same and should match each other.
