*3.1.6 Compatibility with lubricants*

Lower viscosity lubricants with multiple other additives and chemicals are used as lubricants of the transmission for the reasons like reducing the churning losses in the system etc. However, lubricants in the system having influence on the bearing selection and bearing must be suitable to operate and compatible with lubricants in the transmission. Additionally, the sealed bearing application is also common in modern transmissions, so compatible seal material should be selected to avoid damage or performance issues.
