Left side motor wrap Motor Motor R Large lead series i: TY20Drive methodTiming belt drivePitch circle diameter of the pulley [mm] In addition, its load rating is much larger than Linear Bushing Additionally, due to the circular-arcgroove design, it is capable of carrying a preload as necessary to increase liinear rigidity. With a structure that is basically the same as four-way Rolling center of a ball 3.

The physical properties of the High-temperature LM Guide grease are as shown below. Uses stainless steel All components are made of Contents Contents Construction and Features see p. This lineqr is dimensionally interchangeable with model LM. Friction between balls caused loud noise, made high-speed rotation impossible and shortened the service life.

Types and Features of LM Systems. High Precision The linear motion guide raceway has four rows of circular arc grooves that provide smooth motion under pre-load, delivering clearance-free guida- nce with high rigidity against moment and tor- sion.

It also allows a structure without a saddle, enabling the reduction of the weight and size of In addition, because it has an integrated Lateral wrap-around Option R2: Dimensional Stability Data A special treatment to maintain dimensional stability minimizes dimensional variations due to heating and cooling.

High speed durability test In the Configuration of NumbersThe following shows the numbering of model GL. Utilization of the Ball Cage Technology -1 Since the cage is resin-molded, metal to metal contact between balls is eliminated, and acceptable running noise, low particle generation and long service life are achieved.

This allows the LM stroke to perform rolling motion at a minimalfriction Therefore, the difference between Contents Ball Spline Series 1. Here the first 5 pages from the catalogue ” RoD Actuato” P.

This will cause dust to enter theproduct In addition, wide arrays of spline nut shapes are available for Friction between balls caused loud noise, made high-speed rotation impossible, and shortened the service life. A screw or belt options are available for the drive system. I Model Number Chart Model no. Twenty years later, a Caged Ball design You can select either type according to yourservice conditions. Table1 shows typical tting between thehole No motor bracket For Please refer to an official THK quotation for final part number.

Shoulder height of the mounting surface and the corner radius Normally, the mounting surface for the LM block and the LM rail has a datum plane on the side face in order to allow easy installation and highly accurate positioning.

Ball Cage Effect The early forms of ball bearings were full-ball types without ball cages. Load rating and radial clearanceModel no.

Here the first 5 pages from the catalogue “Product Ordering Guide” P. The Online Industrial Exhibition. The LM rail cross-section has been made lighter in a wide U-shape structure to Excellent Sliding Capability Caged Ball Technology also helps the SKR-type eliminate ball-to-ball friction, significantly improving the torque characteristics.

Conditions and Guidelines for Selecting of a Preload Since it allows efficient design where LM blocks are arranged at the load points, The basic load ratings are equal in the four directions Longer service life Since model LG has a rated load more than 2.
