FAQ

Q1:  What is our advantages?
A: Manufacturer - Do it only with the Best;Your Choice make different. 
Q2:  Our Products
A:   Equal-section thin-wall bearings,Linear guide bearings,Deep groove ball bearing,Cylindrical roller bearing,Spherical roller bearing,Needle roller bearing,Angular contact ball bearing,Tapered roller bearing,Thrust ball bearing,Self-aligning ball bearing.
Q3:  Process of our production
A:  Heat Treatment - Grinding - Parts Inspection - Assembly - Final Inspection - Packing
Q4:  How to customize bearing(non-standard) from your company?
A:  We offer OEM,Customized(Non-standard) service and you need to provide drawing and detailed Technical Data.
Q5:  What should I care before installation?
A:  Normally, the preservative with which new bearings are coated before leaving the factory does not need to be removed; it is only necessary to wipe off the outside cylin­drical surface and bore, if the grease is not compatible with the preservative, it is necessary to wash and carefully dry the bearing.Bearings should be installed in a dry, dust-free room away from metal working or other machines producing swarf and dust.
Q6:  How to stock and maintenance my bearings right? 
A: Do not store bearings directly on concrete floors, where water can condense and collect on the bearing;Store the bearings on a pallet or shelf, in an area where the bearings will not be subjected to high humidity or sudden and severe temperature changes that may result in condensation forming;Always put oiled paper or, if not available, plastic sheets between rollers and cup races of tapered roller bearings.
