HYBRID BEARINGS 16 1 New research by QIBR could make hybrid bearings more cost-effective and reliable paving the way for their use in a wider range of applications Hybrid bearings which combine hardened steel rings with rolling elements made of high-performance ceramic materials are an increasingly popular option for demanding applications

For some applications the properties of the bearing with ceramic balls offer functional improvements in several different areas over a conventional all-steel bearing There is a very significant cost penalty for the hybrid ceramic design that largely limits its present-day use to certain high-end applications

Hybrid bearings have rings made of bearing steel and rolling elements made of bearing grade silicon nitride (Si 3 N 4) which make the bearings electrically insulating Silicon nitride rolling elements can extend bearing service life by offering enhanced bearing performance even under difficult operating conditions

LGWA 2 is a premium quality mineral oil based lithium complex grease with extreme pressure (EP) performance LGWA 2 is recommended for general industrial and automotive applications when loads or temperatures exceed the range of general purpose greases Excellent lubrication at peak temperatures up to 220C for short periods

The QIBR Generalized Bearing Life Model for hybrid bearings

Sep 23 2019Hybrid bearings are used in tough application conditions e g poor lubrication and/or high contamination levels [2] [3] Because of the higher stiffness of the ceramic material the Hertzian contact area is slightly smaller in a hybrid bearing leading to higher contact pressure and subsurface stress compared with an all-steel bearing of equivalent geometry

For some applications the properties of the bearing with ceramic balls offer functional improvements in several different areas over a conventional all-steel bearing There is a very significant cost penalty for the hybrid ceramic design that largely limits its present-day use to certain high-end applications
