Product Description:

The FC-051PKFI micro drive is an efficient product of Danfoss. It belongs to the VLT Micro Drive FC 51 series. It is used in industrial automation for tasks such as controlling the speed and torque of industrial motors.

The VLT drive is designed for high pressured applications as it can handle pressures up to 630 bar. This specification makes it a highly flexible device to work in environment having high pressure motors. It's fitting has been done with a tapered stud connection type. This fitting ensures a secure and leak proof fit in a hydraulic system. Also, the fitting is made up of steel material and the nut used are silver plated. This reduces the friction during tightening and also enhances the corrosion resistance. The thread size has a major diameter of 22 mm and has pitch of 1.5 mm. The fitting is designed specifically for tubes that have an outer diameter of 16 millimeters. The drive fitting is compatible with the tubing dimensions most commonly used in hydraulic systems. The FC-051PKFI micro drive comes with a mass equals to 17.9 kg per hundred pieces. This means it is a very small device that can be easily adjusted in small places.

The length of the total threaded portion is 32 mm, while the length of its total fitting is 43 mm. Its inner length is of 24.5 mm while the length of the smaller nut and larger nut is 14mm and 24mm respectively. Its alternative part number is WAL621001 that represents the reference for sourcing or procurement. The fitting can be provided with a stainless steel variant of 1.4571 that offers enhanced corrosion resistance useful for harsh environments.
