HG=Phenolic Resin with Fabric Reinforcement 酚醛夹布

随着温度的增加，PTFE 材料所能承受的表面载荷将降低，其承载能力实际上取决于工作温度，一般而言， 不应超过 150℃。 如使用温度低于 0℃，请先咨询我方
*With the PTFE materials it must be taken into account that the permissible surface pressure decreases with increasing temperatures. The load bearing ability for dynamic applications in practice is dependent primarily on the operating temperature. This should therefore generally not exceed 150°C. For temperatures below 0°C consult technical support.

预切好的导向环在安装后会留有一定的间隙“Z”，这 是基于以下考虑：
--受温度的影响，导向环有一定的线形膨胀
--避免困压
The linear length of DL GST is calculated such that a gap “Z” is created at the ends of the strip after installation. This is required for the following reasons:
-Compensation of the linear expansion of the strips due to the effects of temperature
-Avoidance of intermediate pressures and entrained Pressures.

产品的类型订货时请注明
--切口类型
斜切口是标准形式，直切口和Z型切口需订制
--棱边的倒角形式
无倒角是标准形式。我们可提供棱边为圆角或倒角的形式， 这种设计可防止产品与
沟槽圆角的干涉，也有利于安装。我们可提供成卷的导向带和预切好的导向环。
Forms of Supply
Two characteristics must be observed with respect to the forms of supply forDL
GST.
-Type of cut
The Angle Cut is the most frequently used standard type of cut. Rings with other
types of cut – Straight Cut and Step Cut are available on request.
-Design type
DL GST has a rectangular cross-section with rounded or chamfered edges, thus
preventing impermissible edge forces in the corner radii of the grooves.The
chamfers also serve to facilitate installation, e.g. when inserting into the cylindrical
tube or guide bush.
The ring ends are finished as standard with an angle cut.
Strip material is available in rolls or precut to size to fit with the gap necessary.

压花
厚度等于或大于2mm的PTFE导向带，可提供压花产品。压花结构是在带子的滑动表面
带有微小的润滑微坑，有利于形成润滑薄膜，改善微观润滑， 同时有助于嵌埋微小异
物，保护密封系统。鉴于导向带可用于孔用和轴用导向，一般制作成双面压花。
Empaistic structure
GST up to and including 2 mm radial thickness in PTFE materials are as standard
supplied with Empaistic structure on the sliding surfaces.
This structure comprises small lubricant pockets on the surface which improve
the initial lubrication and promote the formation of a lubricant film. They also
help to protect the seal system through their ability to embed any foreign particles.
In order to be able to use the strip material for both piston and piston rod guides,
the rings have this same empaistic structure on both sides.

When ordering strips off-the-roll for manufacturing of DL GST in your own works,
the length of the strip can be calculated using the following formulae:
For Piston:孔用L=cx(D-W)-k[mm]
For Rod:轴用：L = c x (d + W) - k [mm]
D=Bore diameter 孔径 [mm]
d=Rod diameter 轴径 [mm]
W=Ring thickness 产品厚度[mm]
c = 3.11 material factor 材料因子
k=0.8 for operating temperatures up to 120° C.
k=2.0 only for applications > 120° C.
