High hardness Corrosion - resistant Natural Sapphire Bearing

Product Description

Description of High hardness Corrosion - resistant Natural Sapphire Bearing:

Deep Groove Ball Bearing is the most representative rolling bearing,it can bear axial and bidirectional radial

load.This bearing can be used the occasion with the demand of high rotation,low noise and low oscillation.

Sealed bearing with steel cover or rubber seal usually is filled with lubricant in advance,due to bearing which

outer ring is with stopping circle or flange,it is easier for axial orientation and outer shell's installation. The maximum size of loading bearing is the same as the standard bearing, with filling slot between inner and outer ring. This can help add the number of balls and improve the rated load.

Features of TFN Brand High Speed Miniature Deep Groove Ball Bearing (691) :

• Subject to radial or radial & axial combined load;

• Have positioning action on two axial derections;

• High running precision and low noise;

• Low energy loss and high limit speed;

• Low cost for manufacture and application
