Office automation covers copiers, printers, banking and financial terminals, point-of-sale systems, ATMs and card readers. These devices demand high reliability, low noise and compact form factors; bearings, as the core components of rotary and sliding subsystems, perform critical but often invisible roles in keeping equipment operational.
Materials & Forming — Precision and Durability
By combining advanced materials, precision forming and high-accuracy machining, we develop compact, long-life bearings suited for office gear. Material selection emphasizes low friction, high wear resistance and adequate electrical conductivity. Surface treatments and tight tolerances for rings and rolling elements reduce friction and vibration from the outset, meeting continuous-duty and acoustic requirements.
Lubrication & Conductivity — Electrostatic Control
Static accumulation is a major concern in office devices, especially in financial terminals and document handling equipment. Conductive bearings solve this by incorporating conductive additives into greases to form a stable discharge path for static charges. Since conductive greases can lose conductivity over time or under certain conditions, mission-critical applications often require secondary mechanical grounding methods—such as spring contacts or brushes—to ensure redundant discharge capability.
Sealing & Life — Protection Optimization
Although office environments are relatively clean, paper dust, toner particles and oil mists affect bearing performance over time. Proper sealing designs and controlled lubricant fill levels extend the effective life of conductive bearings. Optimizing seal materials and employing low-volatility, oxidation-resistant conductive lubricants significantly improve conductive longevity and reduce maintenance intervals.
Design Advantage — Smaller and Cleaner
Advances in conductive performance and sealing have eliminated the need for some external grounding mechanisms, enabling more compact and streamlined device architectures. Fewer parts and smaller envelopes not only enhance aesthetic and ergonomic factors but also contribute to energy efficiency and cost savings.
Reliability & Testing — Condition Validation
Conductive bearings must pass rigorous life and conductivity testing, including long-duration operation, thermal and humidity cycling, contact resistance monitoring and simulated electrostatic events. Quantifying conductive lifetime and friction behavior provides traceable reliability metrics for banking and mission-critical office equipment.
