Custom CNC Machined Bronze Wear Bushings for Packaging Automation Lines

Our customer is a European OEM specializing in high-speed packaging automation systems. They required custom bronze wear bushings as replacement wear parts for their production machinery. The original overseas supplier had excessively long lead times, which disrupted their equipment maintenance plan. The customer turned to Chenrong Precision to deliver consistent, high-performance bushings for prototype validation and ongoing serial supply.

The packaging equipment operates 24/7 under repeated reciprocating motion and heavy load.

1. The bushing needs outstanding wear resistance and inherent self-lubricating features to avoid frequent replacement.
2. Strict micron tolerance on inner and outer diameters. Any dimensional deviation would lead to shaft jamming and machine downtime.
3. Batch-to-batch consistency is critical. Inconsistent parts would create uneven performance across multiple production lines.
4. Fast turnaround required to meet their equipment upgrade schedule.

• Material recommendation: We selected tin bronze alloy, which delivers excellent anti-wear performance and self-lubricating properties for continuous friction environments.

• Precision CNC turning: Our team processed inner bore and outer circle to hold tight dimensional tolerance. Fine finishing was applied to lower surface roughness and friction.

• DFM review: Our engineers reviewed the drawing, gave manufacturability suggestions without altering part function.
• Full quality control: Every component was inspected with micrometers. CMM inspection reports were provided with shipment.

• All samples passed the customer’s incoming quality check.
• The bronze bushings run reliably on high-speed packaging lines, showing significantly lower wear rate than their previous spare parts.
• We delivered within the agreed timeline. After successful prototype testing, the customer issued repeat orders for production line maintenance.
