Transmission pump bushings are small, cylindrical components made from durable materials like brass or bronze. They serve as crucial components within the transmission system, providing support and reducing friction between moving parts. These bushings are typically found in automatic transmissions, where they play a pivotal role in maintaining the integrity and functionality of the pump.

• One of the main functions of transmission pump bushings is to reduce friction between the pump’s moving parts. As the transmission pump operates, it generates a significant amount of heat and friction. The bushings act as a barrier, preventing excessive wear and heat buildup, which can lead to costly damage.
• Transmission pump bushings provide essential support to the pump shaft, ensuring its stability and proper alignment. This helps maintain the efficiency of the pump and overall transmission system.

Here are some key benefits:

1. Autonomous Lubrication: One standout feature of these bronze bushings is their ability to achieve autonomous lubrication. This is accomplished through an oil circulator and collar, which function as a viscosity pump driven by shaft rotation. This eliminates the need for an external lubrication system, emergency pumps, accumulators, rundown tanks, or special arrangements for oil lubrication. It also reduces the need for additional motor control systems and electric power, leading to substantial cost savings.
2. Equipment Safety: Traditional systems with electrically driven external lubrication skids can be vulnerable to power interruptions. In contrast, bronze bushings with autonomous lubrication ensure that lubrication continues even in the absence of power. This prevents damage to pump bearings during power disruptions. When the pump is restarted, oil flow immediately resumes as long as the shaft is in motion.
3. Simplified Design & Enhanced Reliability: Bronzeoilless.com’s self-lubricating, non-galling bearing surfaces provide protection against pump failures, especially in cases where pumps may run dry or experience accidental flashing.

Bronzeoilless.com offers casting bronze bushings that find their place in a wide array of pump applications. These applications range from power generation and oil and gas pipelines to multi-stage pumps and water supply and treatment systems. One common requirement in many of these scenarios is forced lubrication, and bronze bushings with grease grooves are designed to meet this need effectively. These bushings are capable of bi-directional operation and can handle load pressures of up to 3.5 MPa and speeds under 60 m/sec. For pumps with higher loads and sliding velocities, plug graphite solid lubricant casting bronze bushings are preferred. Additionally, chrome-copper pads can be employed to dissipate excessive heat from the babbitted face, further enhancing performance.
