Let’s break down the components you mentioned:

1. Linear Guide Rails:

   • You have a set of two linear guide rails available, which come in either HGR15 or HGR20 sizes.
   • The lengths of these guide rails can be 250mm, 300mm, 400mm, 500mm, or 600mm.
   • Linear guide rails are essential for precise movement in machinery, such as CNC routers and 3D printers.

2. Slider Blocks:

   • You also have four slider blocks, which can be either HGH15CA or HGW15CC for the HGR15 rails, or HGH20CA or HGW20CC for the HGR20 rails.
   • These slider blocks allow smooth motion along the guide rails and are crucial for maintaining accuracy in your 3D printer or CNC machine.

3. Application:

   • These components are commonly used in CNC milling machinery for the X, Y, and Z axes.
   • They ensure high precision and stability during movement.

4. Availability and Pricing:

   • The entire set is available for $36.12 (originally $72.25) when you purchase two or more pieces.
