{"title":"OTT-JAKOB","description":"\u003cp\u003eThe OTT-JAKOB collection delivers premium power clamping systems and high-precision spindle components engineered for high-speed CNC machining centers and heavy-duty milling applications. This series features high-performance automatic tool changers, including multi-segmented power strokers, gripper claws (power drawbars), and advanced rotary unions configured for high-pressure coolant (KSS), air, and oil-mist delivery. Engineered for steep tapers (SK\/BT) and hollow shank tapers (HSK), OTT-JAKOB components utilize a unique force-magnification mechanism to guarantee optimal retention force and minimal axial runout under high centrifugal loads. The integration of electronic position monitoring systems (MSU\/All-in-One) provides micro-meter level clamp-stroke diagnostics via IO-Link or analog interfaces, preventing tool pull-out and safeguarding spindle integrity. Our comprehensive inventory ensures the rapid replacement of critical legacy and current-generation OTT-JAKOB spares, maintaining technical compliance with high-RPM spindle geometries and reducing machine tool downtime.\u003c\/p\u003e","products":[{"product_id":"95-250-021-3-0-spindle-swivel-joint-1k-gd-a-ott-jakob-genuine","title":"95.250.021.3.0 Spindle Swivel Joint 1K-GD-A OTT-JAKOB Genuine","description":"\u003ch3\u003e\u003cstrong\u003eCore Engineering Profile\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThe \u003cstrong\u003e\u003cspan style=\"color: #d9534f;\"\u003e95.250.021.3.0\u003c\/span\u003e\u003c\/strong\u003e is a premium \u003cstrong\u003eOTT-JAKOB\u003c\/strong\u003e \u003cstrong\u003e1K-GD-A\u003c\/strong\u003e series rotary union.\u003c\/li\u003e\n\u003cli\u003eEngineered for high-speed spindle integration, this \u003cstrong\u003e95.250.021.3.0\u003c\/strong\u003e model features a \u003cstrong\u003eGD Axial Connection\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eIt utilizes advanced hybrid bearing technology to withstand extreme rotational velocities.\u003c\/li\u003e\n\u003cli\u003eThe unit supports multi-media transfer including coolant, air, and minimum volume lubrication.\u003c\/li\u003e\n\u003cli\u003eDesigned with a closed sealing surface, the \u003cstrong\u003e\u003cspan style=\"color: #d9534f;\"\u003e95.250.021.3.0\u003c\/span\u003e\u003c\/strong\u003e allows for reliable dry operation phases.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eTechnical Data \u0026amp;
