End Cap - Typically, two combined components are used to form a ball return path (simply put, a channel that allows the steel balls to change direction). In a linear guide assembly, two end cap components are installed on both ends of the carriage, respectively, forming a closed-loop ball circulation system.

Circulation tube- It is used to support the steel balls and prevent them from falling out of the carriage before the block is mounted onto the rail.

End Seal - It provides sealing at the outer ends on both sides of the block, preventing dust and chips from entering the ball circulation path.

Bottom Seal - It provides sealing at the bottom of the block, preventing dust and chips from entering the ball circulation path

◆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.

◆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.

◆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. Moreover the temperature rising effect is lower even under high speed operation.

◆Easy for Maintenance
TBI MOTION Linear Guide by TBI is easy for installation even without fixture. The design of seal is combinable either for side seal or inner seal to save material.

◆High Performance without Clearance
Even under a preload or regular load, the ball and raceway contact one another at two points in the loading direction. This design gives rise to a smooth rolling motion.

◆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.

◆Application
Machine tool, Industrial machinery, Electronic application, Semi-conductor industries, X-Y table, Measuring instruments, Medical industry, Pick & go application etc.。

TBI MOTION offers standard and flange type. The assembly height and category are listed below :

Basic Static Load Rating：
If a linear motion system, whether at rest or in low speed motion, receives an excessive load or a large impact, a partial permanent deformation develops between the raceway and rolling elements.
If the magnitude of the permanent deformation exceeds a certain limit, it hinders the smoothness of the motion system.
The basic static load rating refers to a static load in a given direction with given magnitude such that the sum of the permanent set of the rolling elements and that of the raceway at the contact area under the most stress is 0.0001 times greater than the rolling element diameter.
In linear motion systems, the basic static load rating is defined as the radial load. Thus the basic static load rating provides a limit on the static permissible load.

Basic Permissible Moment：
When a Linear Guide gets a force that makes the balls distorted to 1/10,000 of their diameter, we call the force as basic static permissible moment.

Static Safety Factor：
A linear motion system may possibly receive an unpredictable external force due to vibration and impact while it is at rest or is moving or due to inertia resulting from start and stop. It is therefore necessary to consider the static safety factor against operating loads like these.

Service Life：
Even when identical linear guideways in a group are manufactured in the same way or applied under the same condition, the service life may be varied. Thus, the service life is used as an indicator for determining the service life of a linear guideway system.

Basic dynamic load rating：
Basic dynamic load rating can be used to calculate the service life when linear guideway system response to a load. The basic dynamic load rating is defined as a load in a given direction and with a given magnitude that when a group of linear guideways operate under the same conditions.

Calculation of Nominal Life：
The rated life of a linear guide varies depending on the actual applied load. The service life can be estimated based on the basic dynamic load rating of the selected specification and the operating load.
The service life of a linear guide is also influenced by operating conditions, the hardness of the rolling contact surfaces, and the ambient temperature.

Accuracy Standard：
TBI MOTION linear guides are available in five accuracy grades: normal (N), high (H), precision (P), super-precision (SP), and ultra-precision (UP). This allows users to select the appropriate grade according to the accuracy requirements of the equipment.

Preload Selection：
a. The radial clearance of the Linear Guide is the displacement of Linear Guide block caused by the vertical plane when the block is lightly pushed forward or backward at the longitudinal center of the Linear Guide rail secured in place.
The radial clearance is divided into ZF (Slight Clearance), Z0 (No Preload), Clearance Z1 (light preload), Z2 (medium preload) and Z3 (heavy preload). The radial clearance of the Linear Guide significantly affects its running precision, load-withstanding performance, and rigidity.

The clearance designations ZF, Z0, Z1, Z2, and Z3 of TBI MOTION linear guides indicate that the clearance values become negative after preload is applied.
