Thk linear guide rail shs15

Types of THK Linear Guide Rail SHS15

The THK linear guide rail comes in different types, with applications in various industries which need a stable platform for moving machinery parts and components. Here are the renowned types:

• Block

  The component of the linear guide which moves along the rail is referred to as the block. It contains moving parts that roll or slide along the guide rail. Like the guide rail, blocks come in various sizes and load capacities depending on their specific application needs. An example is the THK SHS15R, which is designed with a block that has a simple structure and fulfills various needs.

• Rail

  When a load slides, rolls, or moves over a surface it guides, it is known as a linear guide rail. Usually manufactured using stainless steel, carbon steel, or aluminum alloy, it can be a flat surface or with several grooves. The purpose of guide rails is to ensure accuracy in terms of alignment and control. An example is the SHS rail shape with high rigidity and low friction.

• Unified Assembly

  A linear motion unit integrating a slide rail and a block into one single assembly is called a bush and rail unit. This unifying assembly helps omit the need for precision pairing of the slide and the guide within the moving unit, simplifying construction for an easier further development. Further, it contributes to a more cost-effective solution to meeting an object's need for linear movement to be achieved.

• Drylin

  Due to the predictable nature of the metal-on-metal and the lack of lubrication within it, like all linear guides, the Igus linear guide rail is made to have as little lubrication as possible, even none at all. This is a type of linear guide that is self-lubricating and offers the function of linear motion. The absence of grease reduces dirt build-up, enabling operations to run cleaner.

Specifications and maintenance of the 15 mm THK linear guide

The sections below discuss the specifications and maintenance requirements of the THK SHS15 linear guide rail, including the 15 mm block.

Specifications
