This unit pairs a heavy-duty, corrosion-resistant housing with an integrated, dual-sealed ball bearing insert. Specifically designed for precise linear and rotary machinery—such as custom CNC routers, industrial 3D printers, and automated conveyor systems—it eliminates shaft wobble and accommodates structural misalignments under high-stress operating conditions.Design & Premium FeaturesEngineered for longevity and seamless integration into mechanical frameworks:Self-Aligning Internal Structure: The ball bearing unit features a spherical outer ring that mirrors the curved profile inside the housing cavity. This unique geometry allows the bearing insert to pivot independently, automatically correcting angular misalignments between the support frame and the rotating shaft.Double-Shielded Protection: The bearing insert is outfitted with rubber-reinforced metal seals on both sides. These dual shields trap grease deep within the rolling channels while forming a tight defensive barrier against harmful airborne dust, fine metal shavings, and moisture.Secure Shaft Locking: Features a wide, extended inner ring equipped with dual integrated hexagonal grub screws. When tightened against the inserted shaft, these locking pins create a secure friction hold that prevents axial slipping or rotational spinning along the shaft surface.Rigid Zinc-Alloy Housing: Cast from premium zinc-aluminum alloy, the lightweight bracket delivers structural rigidity and excellent shock absorption while remaining completely resistant to surface rust and atmospheric corrosion.Technical SpecificationsFeatureSpecification DetailsModel DesignationKP004Bearing Type IDK004 (Deep groove chrome steel ball bearing)Housing Block MaterialSolid Die-Cast Zinc Alloy (Zamak series)Internal Bore Diameter20.00 mm (0.787 inches)Mounting Style2-Bolt Horizontal Flange / Pillow BlockMounting Hole SizeM8 Bolt ClearanceLubrication TypeFactory pre-lubricated with lithium-based greaseCommon Use CasesCNC and Automation Drive Shafts: Supporting critical rotational axis loads on ball screws, lead screws, and heavy-duty timing pulley shafts.Large-Scale 3D Printer Frameworks: Serving as a rigid mounting block for internal Z-axis lifting rods and high-tension belt transmission assemblies.Industrial Workshop Machinery: Integrating seamlessly into custom rotary tables, localized material-handling conveyor rollers, or remote-control motorized winch shafts.If you are interested, I can provide a comprehensive diagram breakdown detailing the exact dimensions (height, width, hole-to-hole pitch), or share professional tips on proper shaft tolerances and installation.

Designed for easy integration with microcontrollers like Arduino, Raspberry Pi, ESP32, and PIC, this compact board uses acoustic echolocation to measure physical distances without touching the target object. It acts as an electronic “eye” for automated systems, allowing devices to perceive spatial layouts, calculate gaps, and detect approaching objects in real time.How It Works: Sonic Radar TechnologyThe module features a distinctive dual-metal cylinder design resembling a pair of eyes. This setup contains a matched pair of acoustic transducers:The Transmitter (T): When triggered, this transducer emits a burst of high-frequency ultrasonic sound waves (40 kHz) out into the surrounding air. These sound waves are completely inaudible to human ears.The Receiver (R): If the sound waves hit a physical obstacle or wall, they reflect backwards toward the module. The receiving transducer listens for this echo wave and detects its exact arrival time.By calculating the precise time delay between the sound wave being sent and its return echo, the host microcontroller can use the constant speed of sound in air (roughly 340 meters per second) to calculate the exact distance to the target down to the millimeter.Key Hardware & Operational SpecificationsWide Detection Window: Offers a reliable non-contact measurement range from 2 cm up to 400 cm (approx. 13 feet) with a precision accuracy of up to 3 mm.Narrow Measuring Angle: Possesses an effective sensor cone angle of < 15 degrees, allowing it to focus straight ahead on isolated objects without getting confused by distant side walls.Low Current Consumption: Draws a meager 15mA during active scanning and less than 2mA while idling, keeping power budgets highly optimized for portable, battery-powered robotics.Simple 4-Pin Solderless InterfaceThe module is built with a standard 2.54mm pitch 4-pin right-angle header that plugs directly into electronic breadboards or female jumper wires:VCC: 5V DC Main system power input.Trig (Trigger Input): Receives a brief 10-microsecond high pulse from the microcontroller to command the sensor to blast a sonic wave.Echo (Echo Output): Outputs a logic high pulse whose duration (width) corresponds directly to the total travel time of the sound wave.GND: Central ground connection to tie into your microcontroller’s power plane.Common Engineering ApplicationsObstacle Avoidance Robots: Giving rolling smart cars, drones, and rovers the sensory data needed to dodge walls, furniture, or stairs.Liquid Level Monitoring: Measuring the distance to the surface of water inside storage tanks, wells, or vats without contaminating the fluid with submerged electronic leads.Interactive Installations: Creating smart, motion-activated museum exhibits, greeting displays, or automatic trash cans that open as a person approaches.Digital Parking Guides: Crafting custom garage backing assistance indicators that toggle warning LEDs based on how close a car gets to the rear wall.Would you like a copy of the standard Arduino code template to calculate distances in centimeters, or do you need a wiring guide to connect it safely to a 3.3V microcontroller?You sent: 1 image and said: titel and tagstitel and tagsHere are search-optimized titles and relevant tags tailored for this product:Product TitlesStandard SD Card Module Slot Socket Reader For Arduino / Raspberry PiSPI Interface SD Card Shield Board Memory Module with Level Shifter IC5V/3.3V Dual Compatible SD Card Reader Module for MicrocontrollersTags & Hashtags#SDCardModule #SDCardReader #ArduinoStorage #DIYElectronics #SPILine #MemoryShield #DataLogging #ArduinoProject #RaspberryPi #MicrocontrollerKit #CircuitBoard #TechDIY #EmbeddedSystems #MakerMovement #DataLoggerWould you like a short description or a long description for this SD card module?You said: short discriptionThe Standard SD Card Module Reader is a compact storage breakout board designed to give microcontrollers instant data logging and file storage capabilities.
