6mm diameter ball screw with vehicle hardware

6mm diameter Miniature Ball Screw assembly 0602 for Automatic computer strip machine

The Ball Screw pair can be lubricated to improve wear resistance and transmission efficiency. Lubricants are divided into two categories: lubricating oil and grease. For lubricating oil, use engine oil, No. 90-180 turbine oil, or No. 140 spindle oil. Lithium-based grease can be used as the grease. Grease is added to the threaded raceway and the housing space where the nut is installed, and the lubricating oil is injected into the nut space through the oil hole on the housing.
Ball screw pairs and other rolling friction transmission components, as long as they avoid the entry of abrasive particles and chemically active substances, these components can be considered to work with almost no wear. However, if dirt falls on the raceway or dirty lubricating oil is used, it will not only hinder the normal operation of the balls, but also increase the wear and tear sharply.
Usually a felt ring is used to seal the nut pair. The thickness of the felt ring is 2 to 3 times the pitch, and the inner hole is made into a threaded shape to tightly wrap the Lead Screw and fit it into the groove at both ends of the nut or sleeve.孔内。 In the hole. In addition to soft felt, the sealing ring can also be made of oil-resistant rubber or nylon. Since the sealing ring and the screw are in direct contact, the dustproof effect is better, but the friction resistance torque of the Ball Screw Nut pair is also increased. In order to avoid this frictional resistance moment, a non-contact labyrinth seal ring made of harder plastic can be used, and the inner hole is made into the opposite shape of the screw thread raceway, and a certain gap is left.
For the lead screw exposed to the outside, a protective cover in the form of spiral rigid belt, telescopic sleeve, tapered sleeve, and folding plastic or artificial leather is generally used to prevent dust and abrasive particles from adhering to the surface of the screw. Except that it is similar to the protective cover of the guide rail, one end of these protective covers is connected to the end face of the ball nut, and the other end is fixed on the supporting seat of the ball screw. This can be more solid.
