Bearings are essential components in mechanical design and industrial manufacturing. Although they are small in size, they play a key role in transmission systems. Today we are going to talk about two common but very different types of bearings: Deep Groove Ball Bearings and Linear Ball Bearings. Although they both contain "Ball Bearings" in their names, they are very different in structure, function and usage scenarios. Understanding their differences will help engineers and designers make appropriate selections for different projects.

Density meter is an important instrument used to measure the mass per unit volume of a substance. It is widely used in petrochemical, food and beverage, pharmaceutical, metallurgy, material research and other fields. Due to different application scenarios and measurement objects, there are many types of density meters, which can easily confuse people when selecting. ATO will systematically classify density meters from three dimensions: usage scenarios, measurement media and working principles, and illustrate them with typical examples to help everyone quickly understand the characteristics and uses of various types of density meters.

A fire pump is a specialized device used to increase the pressure and flow rate of water in a fire protection system, such as a sprinkler system or standpipe system, to ensure an adequate water supply in the event of a fire. Fire pumps are designed to deliver large quantities of water at high pressures and are often installed in commercial or industrial buildings as well as in high-rise residential buildings.

An absolute encoder is a detector that outputs angular data to an external target within one revolution of the motor. Absolute encoders are typically capable of 360° output in 8 to 16 bits. ATO.com online store offers single-turn absolute encoders and multi-turn absolute rotary encoders for you to choose from, offering 10-bit/12-bit/14-bit rotary encoders. Below is a price list of some of the absolute encoders in our store for your reference.

A desoldering pump, also known as a solder sucker or tin suckers, is a hand or power tool widely used in electronic repair and assembly, mainly for removing excess solder from circuit boards and helping technicians safely remove electronic components. The desoldering pump is commonly used to repair old circuit boards, replace faulty components, reinstall soldered parts, or perform tin removal cleaning of circuit boards, and is one of the indispensable tools for electronic engineers, repairers, and DIY enthusiasts.

In the previous article, we explored how to control a BLDC (Brushless DC) motor using the I/O+SV control method. In this article, we will introduce another efficient approach: I/O+RV control.

The I/O + SV method can efficiently control the speed and direction of the BLDC motor. This method controls the start and stop and direction of the motor through input signals, and adjusts the speed through variable voltage. In this guide, ATO online store will guide you on how to create a BLDC (brushless DC) motor controller circuit using the input/output (I/O) + speed voltage (SV) control method.

Origin point return control is the control process in the automation system that makes the motion axis return to the preset mechanical origin.
