In modern mechanical systems, most bearings still rely on ball or roller designs. However, self-lubricating bearings are gaining popularity due to their advantages such as oil-free operation, low maintenance, and cost-effectiveness. These bearings are becoming the next big trend in the bearing industry. Self-lubricating bearings offer several key features and benefits: 1. **Oil-Free or Low-Oil Operation**: Ideal for applications where refueling is difficult or impossible. They can function with minimal or no lubrication. 2. **Excellent Wear Resistance**: These bearings have a low friction coefficient, which reduces wear and extends service life. 3. **Elastoplastic Properties**: They can distribute stress over a larger contact area, increasing load capacity and durability. 4. **Low Static Friction Coefficient**: This helps eliminate stiction at low speeds, ensuring precise machine operation. 5. **Reduced Vibration and Noise**: By minimizing oscillations and noise, they improve working conditions and reduce environmental pollution. 6. **Formation of a Lubricant Film**: During operation, a thin layer of lubricant forms, protecting the shaft and preventing dry friction. 7. **Lower Hardness Requirements for the Shaft**: The shaft does not need heat treatment, simplifying manufacturing processes. 8. **Thin-Wall Design and Lightweight**: This reduces the overall size and weight of mechanical systems. 9. **Versatile Surface Treatment**: The steel back can be electroplated with various metals, making them suitable for corrosive environments. They are widely used in printing machines, textile equipment, tobacco machinery, micro-motors, automobiles, motorcycles, and agricultural and forestry machinery. **Analysis of the Gap Series in Self-Lubricating Bearings** 1. **High Load Capacity and Excellent Wear Resistance**: Suitable for slow-speed, high-load applications, including rotary and oscillatory motion. 2. **No Oil Required for Long-Term Protection**: In dry conditions, the embedded lubricant ensures long-lasting performance. 3. **Flexible Processing and Molding**: The outer plastic layer allows for some margin during production, enabling fine-tuning after installation for better fit. 4. **Wide Application Range**: Commonly used in automotive chassis, metallurgical machinery, mining equipment, hydraulic systems, construction machinery, and agricultural tools. **JDB Solid-Inlaid Bearing Series** The JDB solid-inlaid bearing series is a versatile product designed for use under various conditions—high or low pressure, high or low temperature, and even in water or oil-free environments. Made from high-strength brass, it has double the hardness of standard copper bushings and more than double the wear resistance. This series is widely applied in light and heavy machinery, including continuous casting machines, rolling mills, injection molding machines, paper machines, mold guide columns, ships, and machine tools.

CNG Mass Flow Meter

Sealand is a trustworthy manufacturer of CNG Mass Flow Meter, CNG Mass Flowmeter, CNG Flow Meter, CNG Flowmeter, CNG Coriolis Meter, ATEX, IECEx & CE approved.

With its high accuracy, wide rangeability and reliable performance, Sealand meter has been applied in many kinds of industries during the last 8 years. Unlike others who only focus on the measurement of liquid at normal pressure & temperature, Sealand has conquered the difficulty in the measurement under severe conditions, such as high pressure, high viscosity, high & low temperature.
Take CNG (compressed natural gas) for example. As the saying goes, the meter can measure anything else if it can measure CNG. It is quite hard to measure gas under high pressure. The sensor must be able to bear high pressure; in this way, the thickness of flow tube must be increased, so the transmitter shall be more sensitive to detect the signal; however, Sealand made it. Sealand's first model is specially designed for CNG dispenser, and now thousands of this model are put into use on the market.
