This plastic bearing is designed for low-friction rotation in PCB wet-process conveyor systems, helping panels move smoothly while avoiding the corrosion and seizure risks often found in metal bearings.
Core Advantages: Self-lubricating performance, chemical resistance, low-friction rotation, and stable dimensional accuracy.
Selection Recommendations: Choose the suitable bore size, bearing profile, and material strength based on shaft diameter, conveyor load, and chemical exposure.
Applications: PCB and FPC conveyor systems, etching machines, developing chambers, cleaning lines, LCD glass washing equipment, and black-hole processing sections.
Stable Operation Guarantee: Helps reduce bearing seizure, board wobble, track wear, and conveyor downtime during continuous wet-process production.
Eliminate Conveyor Stagnation and PCB Misalignment. In high-speed PCB wet-process environments, metal-to-metal contact or inferior bearings often lead to equipment binding and premature wear. The ID:3136 plastic bearing is engineered to mitigate these failures by offering a self-lubricating, corrosion-resistant solution for conveyor guidance systems. By reducing rotational friction and maintaining precise fit, these components ensure smooth panel transition through aggressive chemical zones. This upgrade effectively prevents board deviation and protects your internal tracks from mechanical fatigue, ensuring that your production line maintains high uptime without constant lubrication maintenance or structural interference.
Engineered for Harsh Chemical Environments
Tailored Geometry for System Integration
These plastic bearings are critical components for high-volume PCB and FPC manufacturing facilities. They are predominantly utilized in horizontal conveyor systems within etching machines, developing chambers, and cleaning lines. Their corrosion-resistant nature makes them an ideal choice for the wet-process sections of LCD glass cleaning lines and black-hole through-hole plating equipment. By providing reliable guidance for rigid or flexible substrates, these bearings ensure that panels remain centered during transit, effectively minimizing the risk of edge damage and conveyor jams during high-speed production cycles.
The primary application for these bearings is the high-traffic zones of conveyor transport systems. By stabilizing the board path, they eliminate the need for frequent line adjustments and mechanical resets. In intensive developing and etching modules, the bearings sustain exposure to harsh chemicals without the metal-corrosion risks associated with stainless steel, significantly extending the mean time between failures for the entire conveyor assembly.
For maintenance supervisors, the real-world ROI is found in reduced spare parts consumption and shortened downtime during periodic system overhauls. These bearings act as a sacrificial but highly durable interface that protects the expensive stainless steel shafting and drive mechanisms from wear. By preventing structural misalignment, they ensure consistent process timing, which is critical for maintaining precise etch rates and development quality across the board.
