1, imported bearings cleaning:
Bearing will be removed when check, use first method such as photography and then record the appearance. In addition, to confirm the amount of residual lubricant and lubricant sampling, and then clean the bearing.
A, bearing cleaning divided into rough washing and fine washing, can be put in use at the bottom of the container and on the metal frame.
B, rough washing, oil using a brush to remove grease or adhesive. If at this time in oil bearing, pay attention to the rolling surface due to foreign bodies such as damage.
C, fine cleaning, slowly rotating bearings in the oil, must be carefully.
Commonly used cleaning agent for neutral aqueous diesel or kerosene, according to the need to sometimes use warm lye, etc. No matter use which kinds of detergent, often should filter clean. After cleaning, coating anticorrosive oil or antirust grease on the bearing immediately.
2, imported bearing inspection and judgment:
To determine remove the imported bearing can be reused, to inspect the dimension precision, rotating accuracy, internal clearance and mating surface, raceway surface, cage and seal rings etc.
About the test results that can be used by bearing the judgement or master of bearing.
Judgment standard according to the mechanical properties and important degree and inspection cycle. If you have the following injury, bearing shall not be used again, must be replaced.
A, fracture and defect of import bearing parts.
B, raceway surface rolling strip below.
Bearing products packaging refers to the bearing after cleaning, anti-rust treatment, to achieve the waterproof, moistureproof, dustproof and waterproof, maintain quality and precision of the bearing, easy to use by the inner and outer packing. Bearing outer packing standard has two: JB/T 3016-2004 "rolling bearing packing technical conditions" and JB/T 4036-2004 the rolling bearing transport in tray and the big wooden cases. In recent years, packaging materials, packaging containers, packaging method, the rapid development of packaging and printing and packaging machinery, effectively promoted the bearing product packaging technical transformation. With China's accession to the wto, commodity competition consciousness enhancement, especially to increase bearing products are exported to participate in international competition in the market, need to develop scientific and reasonable technical standards, to change the "first-class products, the present situation of the second class packing, the price.
1, JB/T 3016-2004
This standard is to JB/T 3016-1991 "rolling bearing nail plate box packaging technical conditions" and JB/T 3017-1991 "rolling bearing packing carton technical conditions" two standards revision. In addition to merge the two standard content, and according to GB/T 1. L - 2000 "the standardization work guide, part 1: standard of the structure and writing rules of the requirements of standard format and edit modification, the standard also made the following revisions:
(1) the standard name changed The revised standard name for the rolling bearing technology condition.
(2) increase the "terms and definitions" chapter
The revised standard increases the "terms and definitions" chapter.
(3) increase the contents of the plastic corrugated box
This is according to the packaging technology and packaging material development at home and abroad and reduce the product cost and promote the needs of the sales increase. Calcium plastic corrugated box production should be according to GB/T 6980-1995 the request of "calcium plastic corrugated box.
(4) modify some terms
Early packaging terminology standard GB 4122-1983 called "wooden" "nail plate box", the new terminology standard GB/T 4122. L - 1996 "packaging this language foundation", GB/T 4122.2-1996 "packaging terms machinery" and GB/T 4122.3-1996 the packing term protection, has cancelled the definition of "nail plate box". According to GB/T 4122.1 the definition, the standard will be "pegboard boxes" instead of "ordinary wooden cases".
(5) to increase recycling of packaging reuse and recycling requirements
Carton is a mainstay of the modern packaging materials, accounts for almost half of the packing material, with corrugated carton consumption is the largest. Corrugated board as a kind of easy recycling environmental protection material is part of the place of wood used for packing products. Starting from the environmental protection and the protection of national natural resources,Clearance Of INA Bearings such as corrugated board recovery and reuse of packaging materials and the requirements of the recycling symbol and use method should comply with the new national standard GB 18455-2001 the request of "packaging recycling symbol.
(6) to modify part of chapter 6 and chapter 7
As the package of the referenced standard revision, changed with the current packaging standards don't match some of the content, uncoordinated.
(7) to delete JB/T 3016-1991 appendix A
JB/T 3016-1991 appendix A is package "stacking test" and "drop test" of test method and the method for determination of the rate of wood and water, drop height than confirmed in the standard of GB 4857.5-1982 pieces of drop test on the packing of the packing and shipping method, asking too low in the appendix. GB/T 4857.5 has been revised to GB/T 4857.5-1992, cancel the appendix to the standard provisions on drop height, so the JB/T 3016-2004 direct references to the new test method standard.
