A railroad car door lock which eliminates the need for lubrication and which includes a bracket, a first base attached to the bracket, a second base attached to the bracket, aligned first and second apertures in the first and second bases for slidably receiving a locking pin, a replaceable first locking pin wear protector lockably insertable in and selectively removable from the first base to prevent contact between the locking pin and the inner edge of the first base which defines the first aperture, and a replaceable second locking pin wear protector lockably insertable in and selectively removable from the second base to prevent contact between the locking pin and the inner edge of the second base which defines the second aperture.

A motor vehicle lock having a locking mechanism with a rotary latch and at least one pawl, comprising an electric drive unit. The drive unit interacts at least indirectly with the locking mechanism, and the drive unit has an electric motor with an output shaft and an output means secured to the output shaft, wherein means for guiding and/or binding a lubricant are arranged between the electric motor and the output means.

A lock which operates reliably and quietly has a locking mechanism with a rotary latch and at least one ratchet pawl for latching the rotary latch. The lock comprises two faces which at least partially bear one against the other and which are at least recurrently displaced relative to one another, with the result that that the displacement causes frictional forces to occur between the faces. At least one frictional face is part of a rotatable component of the lock. A lubricant reservoir is assigned to this rotatable component. There is a feeding means from the lubricant reservoir to the frictional face, which means is configured in such a way that the lubricant is transported from the lubricant reservoir to the frictional face of the rotatable component.
