A variety of innovations for long-lasting lubrication have been developed specifically for high-speed trains by the SKF Group, which can be combined to create bespoke solutions, allowing them to operate with longer maintenance intervals.

Increasing the time intervals between wheelet bearing maintenance visits is the most significant challenge facing the high-speed business today, according to industry experts. According to SKF, for proper operation, a consistent and sufficient supply of oil from the grease to the rolling contact is required to ensure proper operation.

No alternative was available, as it was required for the entire duration of the bearing's service life. Incorrect surface preparation increases the likelihood of surface-induced fatigue occurring, which increases the likelihood of bearing failure if the job is not done correctly.

It has been proposed and developed that a cylindrical roller bearing unit (CRU) be used in order to improve the design of the cage as well as contact between the roller face and the ring flange of the bearing assembly. A high level of stability and low temperatures in the bearing are required in order to achieve this, and the bearing temperature has a direct impact on the life of the grease.

Tapered bearing units (TBUs) allow for the reduction of friction in the rolling contact, resulting in lower bearing temperatures and a longer bearing grease life. Tapered bearing units are used in a variety of applications. Adding a new grease retainer to a bearing increases the amount of grease that can be stored within the bearing while also preventing the accumulation of grease overflow accumulation. The development of a new centrifugal lip (CL) seal has also taken place, which acts as a contact seal at low speeds and converts into a labyrinth seal with minimal friction at higher speeds, allowing for increased efficacy.

SKF has made a number of technological advancements in order to improve the contact between the roller end and the face-flange, optimize the roller-raceway geometry, reduce the roughness of the raceway surface finish, and reduce the wear on the roller end of the roller.
