Qingdao Crane Sealing Technology Co.,Ltd.
It is widely used in papermaking, rubber, chemical, textile printing and dyeing, iron and steel, metallurgical equipment, wind power generation, construction machinery and other industries. For this purpose, it provides a complete after-sales service system and becomes the best partner for many customers.
Crane's products are used in almost infinitely wide fields, and are most widely applicable to various materials, viscosity, temperature, pressure and speed applications. Rotary seal is a unique and specialized product because it must be able to withstand very high pressure while rotating at very high speeds. To achieve this, it is necessary to make the sealing surface achieve a nearly perfect fit, that is, the seal must be slightly overlapped, and can rotate smoothly and stably and friction is reduced to a minimum, in order to extend the service life and ensure no leakage.
