FAQS

QWhat's the Deep groove ball bearings?

ADeep groove ball bearings are versatile, self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies. These products are of simple design, durable in operation and easy to maintain; they are available in single and double row designs and and in open and sealed variants. Due to the production technology used, open bearings can still have turned recesses on the outer ring for seals or shields.

QWhat's the classification of the angular contact ball bearings ?

AThe most commonly used designs are: single row angular contact ball bearings double row angular contact ball bearings four-point contact ball bearings

QWhat's the advantages of Rexroth motor?

A1. Double seal design (bellows + packing) if the bellows fails, the stem packing will also be avoided; 2. Leakage and meet international sealing standards; 3. No fluid loss, reduce energy loss and improve the safety of plant equipment; 4. Long service life, reducing maintenance times and operating costs; 5. The solid and durable bellows seal design ensures zero leakage of the valve rod and provides the conditions without maintenance.

QWhat's the life span of Nb linear motion system?

AWhen the linear motion system undergoes the linear reciprocating motion after the load, the rolling body or the track surface will continue to be subjected to the repeated stress. Therefore, if the linear motion continues for a long time, there will be the fish scale damage caused by the fatigue of the material, which is called peeling off. The total moving distance before this peeling is called the life of the linear motion system. In addition, the linear motion system may not be used due to sintering, cracking, gnawing, rusting and other reasons, but these problems mainly belong to the installation accuracy, environment, lubrication methods and other aspects, which should be treated differently from the service life.
