High material purity, corrosion-resistant and not easy to rust, quality assurance.
Multiple processes are strictly inspected, and each product is delivered as qualified.
The product strictly selects materials, with meticulous workmanship and quality assurance.
The material of the bearing design has been repeatedly verified and calculated to extend the service life o

 

f the bearing.

High carbon chromium bearing steel
A high-quality and long-life bearing steel, the steel used for the ring and washer is SUJ2 high carbon chromium bearing steel that complies with JIS G 4805 standard.
High quality materials
The components made of high-quality materials, precision heat treatment technology, and high-precision processed steel ball paths ensure the long service life of the product, thereby reducing risks and improving efficiency.
Bainite isothermal quenching technology
High strength is used to withstand external loads, resulting in bearings that are super wear-resistant and have a long service life. After bainitic isothermal quenching, rolling bearings obtain high hardness to cope with fatigue deformation.

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.
