Puller spindles: what you need to know

Threaded spindle is a part of machine-tools, nut runners, drills, pullers and other equipment. It is usually made in the form of shaft. Threaded spindle is designed for transmitting the torque from the engine to the tool鈥檚 bit. It transforms rotational motion into translational motion.

Types of threaded spindles

By material:

• Carbon steel. Such spindles are inexpensive. Due to brittleness of the material, they can鈥檛 withstand high loads. They are prone to corrosion.
• Alloy steel. They can be easily treated with heat. Alloy steel spindles feature flexibility and load resistance. They aren鈥檛 prone to corrosion.

By thread type:

• Trapezoidal thread. Such spindles are characterised by high wear-resistance. They are intended for operating at low speeds. This type of spindles withstand high loads.
• Ball screw thread. They are designed for high rotational speeds. Such spindles are used for precision works.

Besides, these tools differ in length and diameter, screw pitch. Consider all these properties when choosing an item.

Tips on using threaded spindles

A new spindle must be installed strictly in accordance with the manufacturer's recommendations after making sure that the spare is in order. While installing the part, prevent dirt from getting onto the thread, otherwise, the tool can get stuck.

Before anything else, make sure that bit is securely fixed. It is dangerous to use equipment with improperly attached parts.
