Each set of DZE precision bearings is coated with anti-rust oil before leaving the factory, and EP2 grease or 7018 aviation grease is added inside the bearings.
DZE bearings are generally packaged in three layers, the first layer: waterproof plastic film, the second layer: kraft paper, and the third layer: packaging bags. Our packaging bags are divided into three types: blue, white, and red. The bearings are marked with the "LYDZC" DZE bearing factory logo; in addition, in order to prevent the bearings from being bumped, we use wooden boxes for all bearings, which greatly reduces the damage to the bearings and bearing packaging.
For RU cross roller bearings, RB cross roller bearings, SX cross roller bearings and harmonic reducer bearings, we use vacuum packaging and add paper boxes on the outside.
DZE precision bearing talents have been vigorously developed. There are 15 senior engineers and 5 postgraduates. The company has cooperated with Luoyang LYC Bearing Co., Ltd. and Luoyang ZYS Bearing Research Institute for many years to jointly formulate industry standards and national technical standards, which has made a significant contribution to the development of the company.
DZE certifications are 3.1, 3.2, ABS, CCS. The company team has technology and rich experience in the bearing industry. With a global network, we can solve any bearing problem for you. DZE bearings are a perfect replacement for the most common and well-known brands.
