Product Description
Interchangeability
For the tightly control of production precision, all the size can
be maintained at as table tolerance range. So the interchange type
linear guide can keep the same smoothness, preloading and precision
when block arbitrarily assemble on the same type of rail. It is
very easy to assemble and repair.
High Positioning Accuracy
When machine that vectoring by linear guide, the friction
coefficient will be 1/50 of sliding frictionco efficient, as the
friction method of linear guide is rolling friction, the disparity
of dynamic friction and static friction will become smaller, when
machine runs, there will be no slipping phenomenon and the
positioning accuracy can reach very high
Four Direction Equal Load Capacity
JSH rail rolling body is to be designed with special pressure angle
which make it can bear the same rated load of its radial, anti
radial and horizontal direction
High Rigidity. High Load
JSH Linear guideway is designed with four columns arc grooves which
increase the contact area, compare with two cloumns groove design
has been greatly improve on the loading capacity ,contact stiffness
and system rigidity.
JSH linear guideway is produced by high precision special plane
which can polyhedrally grind at the same time, detected by laser
and other advanced process . all of these guarantee the
manufacturing precision of TRH linear guideway
Smoothness, Low Noise
The returning device of JSH linear guide adopt a simple and
lubricant ball recirculation design with shocker sistant
circulative accessory -strengthening synthetic resin, the
smoothness of the movement is good which achieves a smooth and
noiseless linear motion.
With automatic self-aligning capability
Arc groove design of the front combination makes the linear
guideway has the ability to automatically adjust the center, even
if to give preloading it can absorb installation error, and
maintains a high precision, smooth and stable linear motion.

Features of Linear Guide
1 High Accuracy
Linear Guide has little friction, only a small driving force is
needed to move the load. Low friction helps the temperature rising
effect to stay low. Thus, the friction is decreased and the
accuracy can be maintained for a long period than tradition slide
system.
2 High Rigidity
The design of Linear Guide features an equal load rating in all
directions that provide sufficient rigidity load in all directions,
self-aligning capability to absorb installation-error. Moreover, a
sufficient preload can be achieved to increase rigidity and makes
it suitable for any kind of installation.
3 Easy for Maintenance
Compared with high-skill required scrapping process of traditional
slide system, the Linear Guide can offer high precision even if the
mounting surface is machined by milling or grinding. Moreover, the
interchangeability of Linear Guide gives a convenience for
installation and future maintenance.
4 High Speed
Linear Guide block, rail and ball apply by contact point of rolling
system. Due to the characteristic of low friction, the required
driving force is much lower than that in other systems, thus the
power consumption is low. More over the temperature rising effect
is lower even under high speed operation.
