Model SHS has the same dimensions as model HSR, which is in effect, the global standard full-ball LM guide, and can be mounted in any orientation since it is 4-way equal load type. With the low sectional height and the high rigidity design of the LM block, SHS achieves highly accurate and stable linear motion. ...
The ball screw is generally driven by a servomotor, which converts a rotary motion into a linear motion through a screw–nut pair. To assess the position-dependent dynamic characteristics of a vertical ball screw feed system subjected to the influence of the screw–nut joint stiffness, a variable-coefficient lumped parameter model of the ...
Linear motion slides and actuators are used to perform movements along a straight line. To do this, actuators convert the rotary motion of a motor into a linear displacement along an axis. This conversion is accomplished using ball screws, lead screws, or belts. To achieve more than one axis of motion, several linear motion slides and actuators ...
Caged Ball LM Guide model SRS has a structure where two raceways are incorporated into the compact body, enabling the model to receive loads in all directions, and to be used in locations where a moment is applied with a single rail. In addition, use of ball cages eliminates friction between balls, thus achieving high speed, low noise ...

A significant benefit of linear rails in these applications is the ability to join multiple rails for very long travel lengths – often exceeding 15 meters. This robot transport unit uses two linear rails in parallel and is able to carry up to 2,930 kg with a maximum stroke of 30 meters. Image credit: Kawasaki Robotics (USA), Inc.

The Thomson linear guide rail assortment consists of: 500 Series Roller Linear Guide Rails. Rigidity is achieved by using the equivalent of a back-to-back ...
outer races that increases load capacity relative to standard round rail guides. The ball track groove in profile rail guides is only slightly larger in radii than that of the balls themselves. The geometry cradles the balls as they infinitesimally flatten under load, slightly expanding the contact area between the balls and the races.
LM fine vertical roller mill. New fine vertical roller mills is developed by our company, it create a particle size distribution with a sharper cut in comparison to cement milled in a traditional ball mill, the compact design allows it to dry, grind and classify, all within one piece of equipment and all in a relatively compact space.
Linear Way VMCs come with large working capacity options of up to 39.4" x 19.7" x 20.5" travels and 43" x 20" table area. The heavy cutting spindle and rigid machine structure enable higher vertical machining efficiency with better finish and longer tool life – resulting in greater productivity and profitability all around.

Generally speaking, lead screws are a more cost-effective system than ball screws, but are only meant for simple positioning functions with low cycles. Often, the lead screw itself is made in the rolling process, and the nuts are made typically of injection molded or machined polymers. These simpler production methods allow for the easy ...
Open the catalog to page 10. Point of Selection Life Calculation Formula If the temperature of the environment surrounding the operating LM System exceeds 100, take into account the adverse effect of the high temperature and multiply the basic load ratings by the temperature factor indicated in Fig.2. In addition, the LM system must be of high ...
With this type, the LM block has a smaller width (W) and tapped holes. It is used in places where the space for table width is limited. The LM block has a smaller width (W), and the mounting holes are tapped. It has the same height dimension as the full-ball type LM Guide HSR-R. The LM block has the same cross-sectional shape as the R
The mistake. One of the more common mechanical mistakes in motion control occurs when designing ball screw- or belt-driven actuators into vertical applications. Typically, both systems have a mechanical efficiency of 90 per cent. In the case of a power loss, however, the motor has no holding torque, which causes the load to come crashing ...
When calculating the vertical offset, the height tolerance, H, of the carriages must be taken into account. If the inclusion of the height tolerance causes a greater offset than is permissible, carriages with …
November 27, 2018. THK - Linear Motion Product News. Linear rail guides are designed for applications that call for precise motion with high load-bearing capability. But improper mounting can add unnecessary loads, reduce life, and undermine the inherent travel accuracy of the linear guide system. Understanding and following the three mounting ...

Following are the advantages of LM Guideways due to which their demand for high precision work is increasing: 1. High Positional Accuracy – When a load is driven by an LM guideway, the frictional contact between load and bed desk is rolling contact. The coefficient of friction is only 1/50 of traditional contact. 2.
Each row of balls in the linear motion guide is arranged at a 45° contact angle, achieving the same load rating in 4 directions (radial, reverse-radial, and horizontal directions) acting on the inner block. It can be used in any orientation. Optimal for end effectors of robot arms that move freely. Wall-mounted Vertical Suspended (inverted)
