A motor includes a rotor, a stator, a bearing, a motor housing, and a sealing member. The rotor includes a shaft. The stator faces the rotor in a radial direction. The bearing supports the rotor such that the rotor is able to rotate about the central axis. The motor housing surrounds at least a part of the stator. The sealing member includes a tubular part and a cover part. The tubular part extends in the axial direction and has an inner surface that faces an outer surface of the shaft in the radial direction with a gap interposed therebetween in the radial direction. The cover part extends inward from an inner surface of the tubular part in the radial direction. The cover part has a through-hole that penetrates therethrough in the axial direction on an inner side from an outer end of the shaft in the radial direction.

A steering column may include a steering spindle that is surrounded by a casing tube and is connected to a steering wheel, a guide clamp in which the casing tube is guided displaceably along a longitudinal axis of the steering spindle. The guide clamp may be mounted pivotably about a pivot axis in a holding part that is connectable to a chassis of the motor vehicle. The position of the casing tube may be adjustable relative to the holding part, and a blocking device may be arranged between the casing tube and the holding part. The blocking device may comprise a threaded rod engaged with a spindle nut. The spindle nut may be mounted in a rolling bearing. Rolling bodies of the rolling bearing may be at least partially surrounded by a magnetorheological fluid, and the blocking device may comprise an electromagnet.

A bearing component such as a bearing ring includes a metallic base body and at least one alloy steel coating on the base body, the coating being applied to the base body by deposition welding. The base body is preferably non-alloy steel or cast iron, and the alloy includes at least one carbide-forming transition metal such as niobium, tantalum, zirconium, titanium, hafnium, tungsten, molybdenum, vanadium, or manganese. The coating can form a raceway of the bearing component or a structural element such as a flange. Also a method of forming such a bearing component is provided.

A machine for manufacturing cables includes a winch that includes a tube, which includes at least a pulley, a reducer and an input shaft to the reducer in its interior. A system for attaching the reducer includes two concentric bearings. An outer bearing is attached to the reducer and the tube, and an inner bearing is attached to the pulley and outer bearing, such that the pulley is supported by the inner bearing and by bearings of the input shaft of the reducer.
