Fasteners for Robotics紧固件在机器人上的应用
Complete fastener design, supply chain solutions and smart warehousing services for robot bodies and core components为机器人本体与核心零部件提供完整的紧固件设计、供应链方案及智能仓储服务
A reliable robot joint starts with a single fastener机器人每个关节的可靠，
都从一颗紧固件开始
Robot joints move constantly under alternating loads and vibration. We supply fasteners by position, so each joint gets the strength, size and locking it needs.关节反复运动，承受交变载荷与振动。我们按部位供应紧固件，让每个连接点用上合适的强度、规格与防松方式。
Our engineers work with you from selection and design through validation, until the fastener is right.工程团队全程参与，从选型、设计到验证，和客户一起把紧固件做合格。
