Linear guideway is as a kind of precision linear guiding parts, it has been more and more widely used in CNC machinery, automatic production line and etc. because of its heavy-load, high-accuracy, high-speed, low-abrasion, reliability and standardization characteristics.
Linear guideway is one of our main products. After over 20 years' production and development, it has GZB, GGB, GGC,HHD,GZD,GZV etc about hundreds of specs and models products presently. We take self-innovation constantly, improve the technology, and upgrade the international market competition. After many years'efforts, we have:
Large: max. Rail 125, max single length: 6m
Heavy load: mass production of roller guide size 35, 45,55,65,85,100 and 125, max single block load capacity is 192 tons
High accuracy: high accuracy, good quality and performance based on many years'advanced production and test technology.
Structure (GGB type)
Linear guideway consists of rail, block, balls, return mechanism, retainer, sealing gasket etc. When the block moves in a linear direction relative to the rail, balls run along four raceway grooves which have been quenched and precisely finished. In the top of the block, balls again pass through the return mechanism into reciprocating hole then into raceway repeatedly. The return mechanism has rubber-sealing gasket on both sides to eliminate dust and keep foreign material away.
By placing appropriate balls between rail and block, friction between the block and the rail changes from sliding friction to rolling friction, which greatly reduced the motion friction resistance. Thereby:
a.The difference between dynamic and static friction is small. It benefits to raise response speed and sensibility of CNC system.
b.The driving power is greatly reduced, which is only 1/10 of the general machinery.
c.The friction resistance reduce 40 times compared to V-shape cross roller guide
d.Suitable for high-speed linear motion, the instantaneous speed is 10 times of than sliding guide.
e.High positioning accuracy and high repetitive positioning accuracy.
It can achieve no clearance motion, raising the running rigidity of the mechanical system.
It has error homogenization effect when using in double guideways, which lower the processing accuracy requirements of rail fixing surface and save the cost of manufacture.
Suitable ratio of radius groove of raceway sectional plane assured that contact force turns small and carrying capacity and rigidity could be also raised greatly. Value of rolling friction is less than that of double-arc raceway.
Surface hardness process makes guideway good calibration and core part keep good mechanical characters.
Simplify the design and manufacture of mechanical structure.
