What Is Oil Groove Bushing?

Oil groove bushings, also known as oil-impregnated bushings, are self-lubricating components widely used in mechanical applications. These bushings are typically made of sintered bronze or casting bronze materials and are infused with lubricating oil during the manufacturing process.

Grease grooves are machined features on the surface of bronze bushings that facilitate the distribution of lubricating grease. These grooves act as reservoirs, allowing the grease to flow between the bushing and the mating surface, ensuring a consistent and adequate supply of lubricant. allowing for continuous lubrication and reducing friction between the moving parts.

Where Should Oil Holes And Grooves Be Located?

Oil holes and oil grooves can only be opened in the non-load-bearing area;
The axial oil groove cannot be opened along the bearing width to prevent end leakage.
Correct Grease Groove Tank Arrangement And Location Selection
To ensure the custom bearing capacity, the bearing with a higher load is better not to open the oil groove. The grease groove of the bearing is best arranged in the low-load area. If the oil hole is arranged in a high load area, it will cause the grease groove pressure leakage, destroy the bearing’s bearing capacity, and cause insufficient oil supply. So the location should be chosen reasonably according to the calculation of the shaft track.

Efficient lubrication is of utmost importance. To achieve optimal lubrication, it is crucial to carefully select high-quality lubricants and employ suitable grooves. These grooves serve as reservoirs for lubricating grease, facilitating its even distribution across the lubrication surface. This uniform coating forms a robust oil film that enhances bearing capacity, effectively reducing friction and minimizing mechanical wear. Therefore, the role of grooves cannot be overstated in ensuring effective lubrication.

Maximizing Performance And Durability With Oil Groove Bushing

oil groove bushing type with oil holes

Oil-Groove Bushings (with Oil Hole) are available in eight styles, to suit different operating conditions, lubrication requirements, and individual preferences.

This type of oil groove has a single radial hole in the bushing wall to allow coolant to flow from a manifold passage to the bushing’s internal oil grooves. Bushing must be correctly oriented during installation so that the radial hole lines up with the manifold passage.

Oil-Groove Bushings (with Oil Hole & External Groove) are available in eight styles, to suit different operating conditions, lubrication requirements, and individual preferences.

This type is our most popular. The OD groove allows coolant to flow around the bushing, then through the radial hole in the bushing’s wall, to the internal oil grooves. This allows installing the bushing at any orientation, and mounting several bushings in series using a single manifold passage.

Oil-Groove Bushings (without Oil Feed) are available in nine styles, to suit different operating conditions, lubrication requirements, and individual preferences.

This type of oil groove does not feature an external feed from a manifold passage to the internal oil grooves of the bushing. Therefore, all coolants must enter through the ID entrance end. It is worth noting that this type is frequently employed as a bearing bushing, typically packed with oil or grease.

Advantages Of Oil Groove Bushings

Beautifully crafted leather products.

Oil groove bushings offer several advantages that make them a preferred choice in various applications:

  • Self-Lubrication: The self-lubricating properties of oil groove bushings eliminate the need for external lubrication, reducing maintenance requirements and associated costs.
  • Friction Reduction: The continuous lubrication provided by the oil grooves minimizes friction, leading to improved efficiency, energy savings, and reduced wear.
  • Longevity and Durability: The self-lubrication mechanism helps prolong the service life of the bushings and the components they support, enhancing overall reliability and reducing downtime.
  • Versatility: Oil groove bushings can be used in diverse industries and applications, withstanding high loads and operating in challenging conditions.
  • Cost-Effective Solution: The extended service life, reduced maintenance needs, and improved efficiency offered by oil groove bushings contribute to cost savings over time.

Bronze Bushing With Grease Groove – Best Practices

When designing grease grooves, it’s essential to follow these best practices for optimal lubrication and component durability:

  • Groove Placement: Strategically position grooves for even lubricant distribution, considering factors like bearing L/D ratio, speed, load, and lubricant viscosity.
  • Groove Dimensions: Calculate groove width and depth accurately to allow sufficient oil or grease flow to maintain desired viscosity within operating temperatures. Recommendations vary for precision, medium, and loose-groove applications.
  • Lubricant Introduction: Ensure oil inlet holes match groove width, with chamfered edges for unrestricted lubricant entry.
  • Consider Load and Speed: Tailor groove design to specific load and speed conditions, choosing suitable configurations for high-load or high-speed applications.

Bushing Grease Groove Design Principle

  1. Ensure that the flow of lubricating oil can meet the requirements of system lubrication and heat dissipation
  2. The lubricant should be fed into the bearing from the point where the oil film pressure is minimal
  3. The grease groove should be opened in the non-load area, otherwise it will reduce the load capacity of the oil film oil groove
  4. Grease groove should not be opened in the axial direction, so as not to lose a lot of oil from the end of the oil groove.
  5. Horizontal mounting bearing oil groove open half circumference, do not extend to the bearing area, the full circumference of the oil groove should be opened near the end of the bearing.
