JF Type Large Heavy Load Ball Screw

Length and heavy load has always been an important problem for manufacturing large heavy duty ball screw to overcome, this series of products to
overcome the design, heat treatment, straightening, raceway forming processing and dynamic detection technology, in the structural design of the
product with a multi-path large-diameter 80 ball circulation loop design structure, the maximum rated dynamic load of the product 126 tons, the maxi mum rated static load of 595 tons. Nanjing Technical Brand is gold Service is heart
Equipment Manufacturing Co., Ltd. has put into use 10 meters large lathe, 10 meters hard rotary milling machine, 10 meters large grinding machine,
10 meters medium frequency quenching machine, 10 meters large straightening machine, 10 meters laser screw (pair) travel error measuring in strument and a series of equipment, taking the lead in establishing the first single 10 meters ball screw production line in China. Among them, the
10-meter laser ball screw travel error measuring instrument has passed the calibration and put into use by Jiangsu Institute of Metrology Science,
which solves the key technology in the dynamic detection process of a single 10-meter ball lead screw p

Product Description

JF Type Large Heavy Load Ball Screw

Notes:

1.Kc is theoretical calculation value when preload Fp is 0.1Ca and axial load F is 0.3Ca.

2.When axial load F is not equal to 0.3Ca,

In formula:

K is rigidity value shown in Table.

3.This type ball screw can be used in high temperature working environment
