Product Description

1.The rings and balls of all-ceramic deep groove ball bearings are made of silicon nitride (Si3N4) ceramic material.

2.This bearing can be designed as a full ball or with PTFE, PEEK or stainless steel 304/316 cage. PTFE is the default standard cage.

3.Full ceramic deep groove ball bearings have the characteristics of non-magnetic and electrical insulation, wear-resistant and corrosion-resistant, oil-free and self-lubricating, high temperature and cold resistance, and can be used in extremely harsh environments and special working conditions.

4.It can be used in high temperature environment above 400ºC under the condition of full ball or equipped with stainless steel 316 cage. The PEEK cage can also be used at temperatures above 250°C. For polar temperatures (for example, lower than -70°C), full ceramic bearings with PTFE cages or stainless steel 316 cages can be used.

5.Normally, the normal radial clearance is C0. When it is necessary to adapt to the extreme environment, other clearances can be customized.
