Pesticides are harmful to pests and can kill them directly. However, if these pesticides are not degraded but remain in fruits and vegetables, they will also cause harm to human health. Studies have found that in the current fruits and vegetables There are mainly three kinds of pesticide residues. They are organophosphorus pesticides, pyrethroid pesticides and organochlorine pesticides such as 666 and DDT. The pesticide residue can detect all three pesticide residues. Therefore, they are used in production, sales, and livelihood. The pesticide residue can help us to effectively prevent the harm of major pesticides. To be sure, the above three types of pesticide residues are harmful to human health. Therefore, how to effectively prevent pesticide residues in fruits and vegetables has always been a matter that production companies, sales companies, consumers, and regulatory authorities hope to solve. The emergence of pesticide residue detectors provides a feasible way for large-scale detection of pesticides in fruits and vegetables. The rapid and accurate analysis and determination of pesticides is performed on the spot, which not only satisfies the need for large-scale sample screening, but also provides effective prevention. The main pesticides and fruits of vegetables and fruits are harmed, and the food safety of agricultural products such as fruits and vegetables is ensured. The use of pesticide residue detectors is simple. Both the unit and the individual can purchase the pesticide residue detector, which is very convenient for pesticide residue testing. Self-inspection of households, enterprises, national industrial and commercial quality inspection, health, supermarkets, farmer's markets, school canteens and other fields can use pesticides to carry out pesticide residue testing, through the source control, circulation supervision and home canteen self-test The method checks all levels to ensure the safety of agricultural products. Therefore, we hope that more supermarkets, canteens, restaurants, production companies, and regulatory agencies will be able to use this type of pesticide testing equipment to ensure the safety of our diet and work hard to build a healthy and harmonious market environment.
eep groove ball bearings or single row radial ball bearings, are the most common type of rolling bearings. Their use is very widespread. It usually consist of a pair of rings, a retainer, a single row of steel balls. The two races are grooved or shaped on their inner surfaces to accept and retain the balls, Single Row Deep Groove Ball Bearings have the highest speed capacity of all rolling element bearings, Deep Groove Ball Bearing is mainly used to bear radial load and operating at relatively high speeds, but it can also bear a certain amount of axial load in either direction.
Feature:
Compared with other bearings, deep groove Ball Bearing has smaller friction coefficient and higher limiting rotate speed, it is more durable and universal with low noise and is easier to install. Deep groove ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races.
Since sliding cannot be eliminated in the contacts between the cage and other bearing parts, the cage itself is the first component to be affected when lubrication becomes inadequate. Our ball bearings use unique design polyamide and steel cage, The inner/outer rings and Retainer(cage) are thicker compare with the Common bearings, stronger rivet, which consist more reliable structure. strong impact and heavy load with Grinding groove and super finishing technology. to offer the long life under extreme harsh environment.
Clearance:
Deep groove ball bearings have internal clearance. This provides the bearing room for expansion between the bearing races and will add a small amount of play between the two rings. Large clearance C3/C4 usually used in harsh environment. with good anti-seize performance used in particularly harsh environment.
Tolerances
The standard version of our single-row deep groove ball bearings has the tolerance class P0
(designs with tighter tolerances available upon request)
Types:
1. Classified according to sealed type:
Open type: Open type deep groove bearings are manufactured without seals to allow for the free circulation of either oil or grease, cost effective solution
Shielded type: With one shield (-Z) on one side or two shields (-2Z/ZZ) on both sides; Shielded bearings are provided with non-contacting metal shields that protect against larger particles entering the bearing, but do not protect against liquids. They add no friction during operation and therefore do not generate heat build-up.
Sealed type: With one seal (-RS) on one side or two seals (-2RS) on both sides. Sealed bearings are supplied with a contacting lip seal that excels in protecting the bearing from liquids and other foreign contaminants. The inherent design creates friction, drag, and in turn heat; factors that require consideration in high speed applications.
2. Classified according to the Retainer/Cage:
Nylon cage deep groove ball bearing: Our KA(Nylon retainer) series bearings Obtained MA certification of China Coal Research Institute, safety certificate of approval for mining products (rollers) in China, with good performance of anti-seize and anti-static.
Steel cage deep groove ball bearing: Thicker cage with stronger rivet, which consist more reliable structure.
Main Products Models And Specifications:
Series 60.., 62.., 63.., Open/ ZZ/2RS..
6200 Series - Light Series Ball Bearings – Balanced between space and load capacity
