A ball screw drive comprises a spindle that includes a torque input portion and a body portion having a ball-screw drive inner raceway, wherein the body portion and torque input portion are met by a support bearing portion of the spindle that includes a support-bearing inner raceway grooved into a surface of the spindle, an outer ring including a support-bearing outer raceway and forming a channel with the support-bearing inner raceway of the spindle, and one or more support-bearing rolling elements arranged in the channel to contact the support-bearing inner raceway grooved into the surface the spindle.

A system for braking a trailer towed by a tow vehicle. The system includes a signalling means for generating an electrical signal based on an action applied by a driver to a brake operating unit. Further, the system includes means for determining weight of the trailer and a brake control unit. Yet further, the system includes a communication means for providing the electrical signal from the signalling means to the brake control unit. The brake control unit being configured to use the determined weight of the trailer to obtain a gain value, calculate a braking power signal value using the electrical signal and the gain value and provide a braking power control signal to an electric braking unit of a wheel of the trailer, based on the braking power signal value.
