What about Oil Groove Bushings
Bronze bushings are manufactured with oil grooves that help lubricate and reduce friction between the shaft and the bushing. This helps to extend the life of equipment and improves performance.
The grooves on the bushing allow the lubricant to flow through the grooves, distributing it evenly throughout the shaft. This lubrication provides a layer of protection that protects the shaft from damage, and it reduces noise and friction between the parts.
Oil groove bushings are available in a variety of materials, including steel and plastic. The choice of material depends on the application. For heavy-duty applications, we recommend using bronze bushings. Bronze is a strong and durable material that can withstand high loads and resist corrosion. It also has a high bearing capacity, which means that it can support a large amount of weight. These bushings are also easy to install and can be used in a wide range of applications. They are also cost-effective, as they can reduce maintenance costs and repair bills.
The grooves on the inner surface of these bushings provide a flow path for lubricant, distributing it evenly across the bearing's surface. This helps reduce friction & wear, which in turn extends equipment life & lowers maintenance costs.
The oil grooves also help to keep dirt & chips out of the bushing's ID, which reduces the likelihood of these items damaging machinery & equipment. To further protect the bushing from debris, it can be ordered with an optional wiper end (order style AA, AB, AD, AE, or AH).

The porous bronze material that makes up Oil Groove Bushings acts as a reservoir to store lubricant and releases it when needed. This self-lubricating function reduces friction, heat, and wear while extending equipment life. They also eliminate the need for additional grease or lubrication, cutting maintenance costs and eliminating the risk of contamination from dirty oils and lubricants.
The grooves that are cut into a bronze bushing are intended to distribute the lubricant more evenly throughout the bearing surface. This helps to reduce the occurrence of pitting and galling, further extending the life of the bushing.
The grooves are cut in a number of ways to suit a range of operating conditions and lubrication requirements. Generally, it is better to remove less metal consistent with conditions than to machine grooves that are too deep or wide. This is because the more surface area that is lost, the more difficult it will be for lubricant to reach its point of contact with the load.
Whenever possible, graphite bushings should be pre-soaked with oil before use. This allows the oil to wick and meter to the bearing areas during shaft motion and can provide extra lubrication when there are periods of boundary lubrication. The oil is re-absorbed by the graphite when motion ceases. This method can provide as much as 2.5 times the load bearing capacity of a bushing with an oil hole only.
Oil grooves are specially designed coolant passageways in a bushing’s ID wall. They can be found on almost all bushing types including press fit, head press fit and renewable. This type of bushing requires external feed from a manifold passage to the internal oil grooves and must be correctly oriented during installation.
These bushings are used to reduce friction and noise in equipment, extending the life of the equipment and reducing maintenance costs. They are commonly used in hydraulic press stabbing boxes, water pumps, diesel engine wrist pin bushings and many other applications.
