3. Pressure Maintenance In many applications, oil seals are designed to maintain pressure within a system. By preventing the exit of oil and the entrance of contaminants, they help in sustaining the necessary pressure levels for optimal operation. This function is especially important in hydraulic systems, where pressure plays a critical role in performance.

One key aspect of Angular Contact Ball Bearings is their preload capability. Preloading eliminates any clearance between the balls and races, enhancing stability and rigidity, and reducing vibration and noise at high speeds Preloading eliminates any clearance between the balls and races, enhancing stability and rigidity, and reducing vibration and noise at high speeds

The 6305 2RS bearing has a bore diameter of 25mm, an outer diameter of 62mm, and a width of 17mm. These dimensions play a significant role in determining the bearing's load-carrying capacity, speed capability, and overall performance. The bore diameter refers to the inner ring's diameter, which is where the shaft will be inserted. The outer diameter is the measurement across the outside of the bearing, while the width represents the thickness of the bearing.
