Product Description

SFR188ZZEE Ball Bearing with 0.25" Shaft Bore and Extended Inner Ring ABEC-5 Precision Rating
Flange Extended Inner Ring Type-Inch

Materials: AISI440C Stainless Steel
Accuracy: ABEC-3, ABEC-5
Bore Size: 0.25"
Outer Dia.: 0.547"F
Width: 0.1875"F
Load Rating & Life: 
SGC miniature bearings are manufactured with state-of-the-art technologies.Therefore,the rated dynamic load of the productions is 30% higher than the rated dynamic load regulated by the ISO281/1 Standards;the rated static load complies with the ISO76 Standards.Customers may calculate the service life of the bearings according to the method provided by ISO281/1 Standards.
 
Lubrications:
Before SGC miniature bearings leave factory,the open bearing is filled with meter anti-rust oil only;while the shielded bearing has been filled with general bearing grease,which makes it suitable for light and medium load as well as low and medium speed applications, with a working temperature ranging from -30ºC~100ºC.If the bearings are applied beyond the above conditions, other special grease or lubricating methods shall be employed.
