1, cleaning the bearing removed the inspection, the first use of photography and other methods to make a good appearance record. Also, check the amount of lubricant remaining and sample the lubricant before cleaning the bearings. a, bearing cleaning points washed and fine wash, and the bottom of the container can be placed on a metal grid. b, rough wash, remove the grease or adhesive in the oil with a brush. At this time if the bearing rotation in the oil, pay attention to damage due to foreign bodies rolling surface. c, fine cleaning, slowly turning the bearings in the oil, to be carefully carried out. Commonly used cleaning agents are neutral, non-aqueous diesel or kerosene, sometimes depending on the need to use warm lye and so on. No matter what kind of cleaning agents, should always be filtered to keep clean. After cleaning, apply anti-rust oil or anti-rust grease on the bearing immediately. 2, inspection and judgment In order to determine whether the removed bearings can be re-used, we should focus on checking its dimensional accuracy, precision, internal clearance and with the surface, raceway, cage and seals. On the test results, can be used to master the bearings or proficient who judge. The criteria for judging vary depending on the mechanical properties and the degree of importance, the inspection cycle, and the like. If the following damage, bearings can not be re-used, must be replaced. 1) bearing parts of the fracture and defects. 2) raceway rolling surface of the peel.

Fiberglass Cloth

Fiberglass cloth has become a widely used material in various industries due to its exceptional strength, versatility, and heat resistance. This cloth is made from woven strands of fiberglass, resulting in a lightweight yet durable fabric. With its high tensile strength and resistance to chemicals, abrasion, and extreme temperatures, fiberglass cloth finds applications in a wide range of fields. It is commonly used in the manufacturing of composite materials, insulation, and protective coverings. The flexibility and moldability of fiberglass cloth make it an ideal choice for reinforcing structures, creating custom shapes, and providing insulation. Whether in construction, automotive, aerospace, or marine industries, fiberglass cloth offers a reliable and efficient solution for numerous applications.
