When dealing with SKF imported bearings, it's essential to follow proper installation procedures to ensure their performance and longevity. The first step involves preparing the bearings. Since they are usually packaged with anti-rust protection, it's recommended not to open the package until you're ready to install them. The anti-rust oil applied on the bearings helps maintain smooth operation. For general use or bearings pre-lubricated with grease, no cleaning is required before installation. However, if the bearing is intended for outdoor use or high-speed applications, the lubricant may be washed off, leaving the bearing vulnerable to rust. In such cases, avoid leaving the bearing exposed for extended periods. Next, inspect the shaft and housing to ensure there are no burrs, scratches, or foreign particles like silicon carbide (SiC) or aluminum oxide (Al₂O₃). It's also important to verify that the dimensions, shape, and surface finish of the shaft and housing match the design specifications. When installing SKF bearings, the method depends on the type of fit. Most often, the inner ring requires an interference fit because the shaft rotates. For cylindrical bore bearings, a press or heating method is commonly used. For tapered bore bearings, installation can be done directly on a tapered shaft or using a sleeve. For the outer ring, a clearance fit is typically used, while the outer ring itself might require an interference fit. Pressing or cold shrinkage methods are common. When using dry ice as a coolant, condensation can form on the bearing’s surface, so appropriate anti-rust measures must be taken. Proper installation of SKF bearings is crucial for their performance, accuracy, and lifespan. Before installation, it's important to thoroughly study the bearing and its mating parts. Follow the manufacturer’s operating guidelines, which generally include: 1. Cleaning the bearing and related components. 2. Checking the dimensions and surface condition of the mating parts. 3. Installing the bearing correctly. 4. Ensuring proper lubrication. 5. Verifying the final assembly. By following these steps, you can significantly improve the reliability and efficiency of the bearing system.

Pulse Distance Sensor

Pulsed laser ranging module is a module that uses pulsed laser technology to measure distance. It emits a series of pulsed laser beams and calculates the distance between the target object and the module by measuring the round-trip time of the laser beams.PTFS has high ranging accuracy and long ranging range, strong anti-jamming ability, support for secondary development, a large number of ranges, safe for the human eye 905 nm, customizable frequency (20-3500 Hz), available for both indoor and outdoor. It can be widely used in speed measurement, displacement measurement, distance measurement and other fields.

Pulse Long-range laser distance sensors can measure distances of hundreds of meters to several kilometers, suitable for wide-area measurement and long-distance monitoring. These sensors are crucial in fields like surveying, Geographic Information Systems (GIS), mining, and drone mapping. For instance, in drone mapping, long-range laser distance sensors quickly acquire extensive terrain data, supporting the creation and updating of GIS.
