Standard Linear Guides（Nominal Part Number：12W）

Linear guides are essential components in the world of machinery, enabling smooth, precise, and controlled motion along a fixed path or rail. Different manufacturers refer to them by various names – they're called linear guides by MISUMI, LM Guides by THK, NSK linear guides by NSK, Linear Ways by IKO, and slide guides by NB.A key feature of linear guides is their ability to maintain steady and consistent movement without rattling, thereby significantly reducing mechanical errors and increasing overall operational efficiency. MISUMI's linear guides, manufactured by the Suruga Production Platform, are renowned for their quality and variety. They offer an extensive product lineup, ranging from miniature guides suited for small-scale operations to medium and heavy-load types designed to handle more rigorous industrial applications. These guides are available in different sizes, materials, and precision levels, tailored to fit your specific needs. One standout feature of MISUMI's linear guides is their flexibility – rails can be specified in 1 mm increments, providing a customized solution for various applications.In addition to the main linear guide unit, several peripheral parts enhance the performance and usability of these systems. These include a cap for protecting the guide's moving components, a clamper for secure positioning, a linear lock for enhanced stability, and a stopper to limit the guide's motion. Additionally, a block provides a stable platform for mounting other parts, and bellows offer additional protection against dust and other external contaminants.If you need a precise linear guide for small projects or a robust one for large-scale tasks, consider MISUMI's wide range, customizable features, and top-quality manufacturing, which can enhance your operation's efficiency and effectiveness.

Caged Ball LM Guide, Miniature, SRS Type

THK

A miniature type with a compact structure. Can be mounted in areas where space is at a premium. Part of the LM block is made of resin for a lighter overall weight.
[Features]
· The adoption of the ball retainer has eliminated mutual friction between the balls, providing excellent high speed characteristics, low noise, good sound quality and a long lifespan, and keeps it maintenance-free for an extended period.
· The ball retainer eliminates mutual friction between the balls, improving how well the grease is maintained and reducing the amount of dust raised.
· The LM block and LM rail are both made with highly rust-preventive stainless steel.
· The rail cross-section height is kept low, and it has a compact structure with a single ball row on the right and left, allowing it to be mounted in areas where space is at a premium.
· A lightweight and low-inertia type where part of the LM block (around the ball escape hole, etc.) has been molded with resin using insert molding.
[Applications]
· Surface grinders,electric discharge machining, high-speed conveyors, NC lathes, injection molding machines
· Woodworking machines, semiconductor manufacturing devices, inspection devices, food processing machinery
