Product Details

1.Automatic alignment: It can automatically adjust the deviation and clearance of the bearing during installation or use to ensure the normal operation of the bearing.
2.Strong load-bearing capacity: It can withstand large radial and axial loads and is suitable for heavy-load applications.
3.Strong adaptability: suitable for construction machinery, metallurgical equipment, excavators and other equipment that need to withstand large loads and high speeds.
4.Strong wear resistance: using high-quality materials and precision processing, it has a long service life.
5.Dust-proof seal: Some models are equipped with dust-proof sealing rings, which can effectively prevent dust and foreign matter from entering the inside of the bearing.

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.
