AirTAC LSH15BK-F1N-N-D-AM6 Linear Guide Block | 15mm Flange Type with AM6 Adapter

Model: LSH15BK-F1N-N-D-AM6

1. Executive Summary

The AirTAC LSH15BK-F1N-N-D-AM6 is the most compact 15mm flange-type block in the LSH heavy-load linear guide series. It is specifically designed for light automation equipment where space is tight, yet high stability is required. Despite its miniature dimensions (assembly height of only 24mm), the F1 wide-body flange design provides torque resistance far superior to standard square blocks of the same size. Additionally, this model comes standard with an AM6 adapter, converting the originally tiny M4 oil port into a universal M6 interface, significantly simplifying equipment maintenance.

Focus on Differences: Please pay close attention to the following details.

• LSH: Series Name — Standard Heavy-Load Linear Guide (High Assembly Type).

• 15: Size Specification — Nominal rail width of 15mm.

  • Positioning: This is the smallest size in the standard heavy-load series, balancing miniaturization with high rigidity.

• BK: Block Component — Indicates this is an independent block unit.

• F1: Block Type — Flange Type, Top Mounting.

  • Core Feature: "Wings" extend from both sides of the block, reaching a total width of 47mm.

  • Mounting Method: The flange has through-holes; screws pass through the top of the block to lock onto the workbench.

• N: Block Length — Standard Length (Non-extended).

• N: Precision Class — N Class (Normal/Standard), satisfying the vast majority of light industrial automation needs.

• D: Pairing/Interchange Code — Group D Pairing.

  • Designed for maintenance and interchangeability. It ensures the block groove tolerance falls within Group D, guaranteeing stable preload when matched with Group D rails.

• AM6: Grease Nipple Spec — M4 to M6 Adapter.

  • Important Detail: Regular 15mm blocks are too small and usually only have M4 threaded holes. The code "AM6" indicates a factory-installed stainless steel adapter that converts this to a standard M6 grease fitting. You can use common grease guns or M6 automatic oil pipes directly, without buying special miniature oiling tools.

3. Core Features

A. Extreme Compactness & High Stability The 15mm specification is the "Golden Size" for light equipment. Through the F1 Flange design, the block width expands to 47mm (compared to only 34mm for square types). This greatly increases the mounting base area, allowing a single rail to withstand significant Rolling Moments (side-to-side tilting forces).

B. AM6 Maintenance Convenience Lubricating 15mm micro-blocks is usually troublesome (requiring specialized needle-nose grease guns). The addition of the AM6 adapter is a highly user-friendly upgrade. It makes this small block directly compatible with factory existing M6 lubrication systems, drastically improving maintenance efficiency.

C. D-Class Precision Interchangeability As a consumable part, the biggest fear when replacing a block is mismatched tolerances. D-Class pairing ensures the fit gap between the block and rail is just right—neither too tight (causing motor overload) nor too loose (affecting printing or engraving accuracy).

D. Four-Row Heavy-Load Structure Although small, this is not a "Miniature Guide." It features an internal structure with 4 rows of steel balls and a 45-degree contact angle. Its load capacity (Dynamic Load Rating approx. 11.38 kN) is far higher than double-row miniature guides of the same size (such as the MGN15).

4. Technical Specifications

Please verify dimensions carefully, especially height and hole spacing:

• Compatible Rail: AirTAC LSH15 Series (Rail width 15mm).

• Assembly Height (H): 24 mm (From bottom of rail to top of block).

  • Comparison: LSH20 is 30mm, LSH25 is 40mm. This is the lowest profile version.

• Block Width (W): 47 mm (Total width with flange).

• Block Length (L): Approx. 66 mm.

• Mounting Hole Spacing: 30 mm (Transverse) x 26 mm (Longitudinal).

  • Interchangeability: This spacing complies with international standards (e.g., HIWIN HGW15CC) and allows for direct replacement.

• Mounting Hole Type: 4 x M4 through holes.

  • Installation: Use M4 bolts passing from top to bottom to lock the block.

• Dynamic Load Rating (C): Approx. 11.38 kN.

• Static Load Rating (Co): Approx. 16.9 kN.

5. Target Applications

The LSH15BK-F1N-N-D-AM6 is suitable for scenarios requiring miniaturization and lightweight design, but with high rigidity:

• 3D Printers (CoreXY Structure): High-speed movement axes for print heads; the flange type offers excellent print head stability.

• Desktop CNC Engravers: X/Y/Z axis guidance, resisting vibration during cutting.

• Small Robotic Arms: Gripper opening/closing mechanisms or end-effector rotation.

• PCB Drilling Machines: Precision feed for circuit board processing platforms.

• Medical Equipment: Slide mechanisms for automatic blood analyzers.

6. Final Checklist Before Purchase

The 15mm size is very easy to buy incorrectly. Please ensure you measure:

1. Measure Total Height: When the block is on the rail, the total height must be 24mm. (If it is 28mm, that is the High-Assembly HGH15 type, not this model).

2. Measure Hole Spacing: The center-to-center distance of the 4 screw holes must be 30mm x 26mm.

3. Check the Side: Confirm there is a protruding metal adapter (AM6) on the side of the block; this is a signature feature of this model.

4. Confirm Screws: Is your mounting surface tapped for M4? (This block is used with M4 screws).
