Model

MGN15H

Block Type

H (Long/Extended Type) - offers superior rigidity, load capacity, and moment load resistance compared to the 'C' (Standard) type due to its increased length.

Compatible Rail Width

15mm (designed to run on MGN15 linear guide rails)

Block Width (W)

Approximately 32mm

Block Length (L)

Approximately 58mm - 58.8mm

Block Height (B)

Approximately 25mm (width of the bottom mounting surface)

Overall Height (H)

Approximately 12mm (block height from top to bottom)

Overall Height (with Rail)

Approximately 16mm - 18mm (when mounted on a standard MGN15 rail)

Material

Bearing Steel (most common for block body, recirculating balls, and raceways, providing high hardness and wear resistance). Stainless Steel (often available for improved corrosion resistance, e.g., SUS440C, for humid or cleanroom environments).

Internal Design

Features precision steel balls in a circulating system within raceways. Includes a ball retainer/holder to prevent balls from falling out when the block is removed from the rail, aiding in handling and maintenance.

Load Bearing

Employs a Gothic arch or 4-point contact design, allowing it to sustain balanced loads from all directions (radial, reverse radial, and lateral). This design ensures high rigidity and accuracy under various loading conditions.

Dynamic Load Rating (C)

Typically 4.6 kN - 6.37 kN (approx. 470 kgf - 650 kgf). Note: Exact values vary by manufacturer; consult specific datasheet.

Static Load Rating (C0)

Typically 5.6 kN - 9.11 kN (approx. 570 kgf - 930 kgf). Note: Exact values vary by manufacturer; consult specific datasheet.

Lubrication

Equipped with a grease fitting/nipple for easy lubrication. Regular lubrication is essential for maintaining smooth, low-friction movement and extending the service life of the linear guide.

Precision Grade

Commonly available in various precision grades: C (Normal), H (High), P (Precision). "Normal quality" Chinese blocks typically refer to C or H grades.

Interchangeability

Often designed for interchangeability, meaning individual blocks and rails can be replaced separately (within specified precision tolerances). This simplifies logistics and maintenance.

Movement Characteristics

Provides extremely smooth, precise, and quiet linear motion with very low friction, making it ideal for applications requiring high positional accuracy.

Weight

Approximately 90g - 110g (varies slightly by manufacturer and material)

Mounting Holes

Typically has threaded M3 holes on the top surface for attaching carriages, workpieces, or other fixtures. Standard mounting hole spacing (PCD) is usually 25mm.
