Product Introduction

Tungsten carbide sleeve applications is wide, which is a device to protect a class of components. It is in the actual work and the role and purpose of its application environment have a great relationship.
Valve applications, bushings be installed in the valve stem cap trap, in order to reduce the valve leakage, to seal; bearing applications, the use of bush to reduce wear between the bearing and the shaft seat, avoid the gap between the shaft and the hole increases and so on.
Tungsten carbide sleeve production and processing of high-strength, can withstand prolonged load, with high chemical stability, alkali, alcohol, ether, hydrocarbons, acid, oil, detergent, water (sea water), and has no smell , non-toxic, tasteless, non-rust characteristics, its widely used in petrochemical industry for Submerged Oil Pump, slurry pump, water pump, Centrifugal Pump,etc.


1, 100% Raw material:
Bushings are produced with pure raw materials, which has the characteristics of long service life and stable performance.
2, Maching:
Bushings is processed by high-precision equipment:CNC machining center, grinding machine, milling machine, drilling machine,horizontal milling machine, chamfering machine, Metal Stamping ,CNC cutting machine etc.
3, Multiple sizes available:
We can provide bearing bushings different sizes, complete molds and short delivery time.7-10 days for samples .20-25 working days for mass productions
4,Quality assurance:
Unsurpassed Quality Standards.Our bushings sleeves bearings are designed and manufactured according to stringent quality standards that govern material selection, machining, surface finishing,inspection and packaging.
