Model

MGN9H

Block Type

H (Long/Extended Type) - provides greater rigidity and load capacity than 'C' (Standard) type.

Compatible Rail Width

9mm (designed to run on MGN9 linear guide rails)

Block Width

Approximately 20mm

Block Length

Approximately 39.9mm - 40.5mm

Block Thickness (Height)

Approximately 8mm (excluding overall height with rail)

Overall Thickness (with Rail)

Approximately 10mm

Material

Bearing Steel (common for block body and balls) <br> Stainless Steel (sometimes available for better corrosion resistance)

Internal Design

Utilizes steel balls in a circulating system. Often features a ball retainer to prevent balls from falling out when removed from the rail.

Load Bearing

4-point contact design, allowing it to bear load from all directions. Offers good rigidity and high accuracy.

Lubrication

Includes an oil inlet/nipple for easy lubrication. Lubrication system helps maintain smooth movement and extend lifespan.

Precision Grade

Typically available in various precision grades (e.g., C - Normal, H - High, P - Precision). "Normal Quality" Chinese blocks usually correspond to C or H grade.

Interchangeability

Often designed with ball retainers that allow for interchangeability (replacing block or rail separately) for small precision requirements.

Movement Characteristics

Smooth and precise linear movement, low friction, low noise.

Weight

Approximately 20g - 40g (varies slightly by manufacturer)

Mounting

Typically has threaded holes on top for mounting fixtures or carriages (e.g., M3 bolts).
