We could design and manufacture 6300~6310 ZZ ball bearings according to your requirements.Welcome to inquiry.
Nide takes special car with its raw material used in its bearings. The raw material applied in the bearing rings and rolling elements is from the companies that sell same quality material to world top class bearing manufacturers in Japan and Europe. Also, NIDE's latest computerized heat treatment system and technology distinguish NIDE brand bearings form others. It helps the bearing material to reach the characteristics of high level of hardness, high rolling contact fatigue resistance, excellent wear resistance, dimensional stability and excellent mechanical strength which is essential to delay the advent of material fatigue.
Cage material
Material for cages is required to have properties of good wear resistance, dimensional stability and good mechanical strength. Cold-rolled steel is used for pressed cages.

Polyamide resin is applied depending on the type of bearing and the application, but should not be used at temperatures above 120℃ or below -40℃. Polyamide cages may be affected by the use of specific lubricants. Brass cages are not suitable in Ammonia(eg in refrigeration) because Ammonia causes cracking in brass. So for selection of cage material, it is important to consider the operation conditions.
