Ball Screw :-
A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction. ... As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction. Common applications are linear actuators, machine slides (such as in machine tools), vices, presses, and jacks.Most demanding characteristics of ball screws are the precision in positioning, the load carrying capacity and the high speeds of rotation.
NHB supplies chrome steel balls for this application in a large spread of gauges to allow the manufacturers to assemble the finished products with controlled radial and axial clearance, two important parameters to guarantee the precise positioning. For high speed applications NHB can supply the Super Premium specification to allow smooth and silent functioning.
To serve customers NHB can offer required gauges – even in small quantities – through Just in Time concept.
Construction & Heavy Machinery :-
In heavy and construction machinery, bearings are sometimes exposed to extreme operating conditions – excessive loads, contaminated environments, rough weather, etc. the main important component which ensures the smooth function of bearing are balls.The main difficulty in providing high quality large balls consists of the capability to achieve proper metallurgical structure also in the core of ball section.
This result is achieved by NHB through special quality control of heat treatment furnaces that minimize the process variation and maximize the life performance in the large bearing.
Another trend in place is about the market need of more and more silent large bearings, that requires superior geometry to steel balls. For this reason NHB can supply large steel balls in Electrical Standard Quality ESQ
