Ball screw assembly is consisted of screw, nut and balls. It is to transfer the rotary motion into linear motion or transfer the linear motion into rotary motion. Ball screw is widely used for all kinds of industrial equipments and precision instruments. Especially in recent years, it is widely used in CNC machine tools. Yigong ball screw is made by grinding and whirling, not rolled, and it has two kinds of ball screw P for positioning and T for transmission,

Angular contact ball bearing is entad thrust ball bearing, it can loaded many steel balls, so itsradial bearing capacity is greater than the ordinary ball bearings, it can also accept a lot of the axial load, or pure axial which allow working speed similar to deep groove ball bearing ,with deeper rigid, but the precise requirements for the axes of error is very sensitive, it is not generally used to separate withstanding the radial direction load, when withstanding the radial direction load

1. The notes of the corrosion for the sliding bearings As the main bearing pad and connecting rod bearing of the sliding bearings, the main malfunction during work is the peeling or burning loss of the antifriction alloy and the abrasion of the bearing in the early stage.The surface of the bearing pad will have quick breakage or heavy wear after the short term operation of the diesel. The situation is not caused by the bearing pad itself but by the badness

Roller bearings and ball bearings are rolling bearings. All simple terms, a rolling body is a steel column. Another is the ball rolling, that is, the so-called ball.Said first roller bearing:Rolling bearing is a kind of cylindrical roller bearings to the heart. Cylindrical roller in line contact with the roller bearings. Load capacity, mainly bear radial load. Rolling ring wall with small friction, suitable for high-speed rotation. Whether under the ring wall, divided NU, NJ, NUP, N, NF

Ceramic bearing and ceramic ball bearings have many excellent properties such as: self-lubricating, high temperature, corrosion resistant, magnetic, electrical insulation, etc.. Yet in the wider field of development and utilization of potential, their applications are huge. The first high-quality and high-speed ceramic ball bearings do excellent services to the domestic machine tool industry. The high-speed, high precision spindle and spindle bearing own a large amount of the estimated annual demand, which picked up in a few million more.

By heating the bear and bearing carrier,thermal dilation will change the tight matching to loose matching. It is a commen way to install. it is suitable for installation the interferenced bearing,heat the bear Or splited bearing in the oil tunk to 80-100℃ before installation,then take it out and install it to the rod quickly,to avoid the inner collar cann't match the shaft shoulder well. Fastening axial after cooling down.When installing the outside collar and bearing carrier which is made of light metal

The structur of Linear motion ball bearing is built a retainer in the outer ring , retainer with multiple balls, and make infinite loop movement. Within the spring retainer ring fixed at both ends,there is the gap with the work force in the ball straight track side window. This section is to allow the load axis for rolling contact with the ball. With a very low coefficient of friction is relatively mobile, so linear motion ball bearings for the machinery and equipment,
