AirTAC LSH15BK-HN-N-B-AM6 Linear Guide Block | 15mm Square High Assembly w/ AM6 Adapter

Model: LSH15BK-HN-N-B-AM6

1. Executive Summary

The AirTAC LSH15BK-HN-N-B-AM6 is the standard 15mm square block in the LSH heavy-load linear guide series. It is designed for compact equipment that is space-constrained but requires industrial-grade precision. As the smallest "High Assembly" square model in the series, it not only provides the standard 28mm assembly height but also features a factory-standard AM6 stainless steel adapter. This adapter converts the originally microscopic M4 oil port into a universal M6 interface, making maintenance unprecedentedly simple. Additionally, the "B" code indicates it belongs to Pairing Group B, offering excellent universal interchangeability.

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

• LSH: Series Name — High Assembly Standard Linear Guide.

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

  • Positioning: The smallest size in the heavy-load series, balancing compact volume with high load capacity.

• BK: Block Type — Square Block.

  • Feature: No side flanges. The width is only 34mm, making it ideal for installation in narrow grooves or dense arrangements.

• HN:

  • H: Accuracy Class — High Class.

  • N: Preload Class — Standard/No Preload (Runs lightly with minimal friction).

  • N: Dust Protection — Standard (End seals).

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

  • Meaning: This indicates the block's dimensional tolerance falls within Group B. In AirTAC's interchange system, Group B is a standard general-purpose pairing group (similar to Group D). When purchasing spare parts, if your old part code is B, selecting this model ensures the optimal fit clearance.

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

  • Pain Point Solution: Standard 15mm blocks typically have only M4 threaded holes, which standard grease gun nozzles cannot fit. AM6 is a pre-installed L-shaped or straight adapter that converts this to a standard M6 thread, allowing you to use existing factory standard lubrication equipment directly.

3. Core Features

A. Minimalist Maintenance (Maintenance Friendly with AM6) On 15mm micro-guides, "difficult refueling" has always been a headache for frontline engineers. The LSH15BK-HN-N-B-AM6 solves this by coming factory-equipped with the AM6 adapter, making it directly compatible with M6 grease nipples or automatic lubrication lines. This eliminates the need to source specialized miniature grease guns, significantly lowering long-term maintenance costs.

B. 28mm Standard High Assembly Unlike the Flange type (HGW/LSH-F) which has a low center of gravity (24mm height), this BK Square Block follows the standard dimensions of the HIWIN HGH15CA. The total assembly height is 28mm. This design provides more internal space for steel ball circulation, resulting in higher load capacity, and is fully interchangeable with international standards.

C. Compact Narrow Body Design The block width is only 34mm (compared to 47mm for the flange type). This allows it to be easily installed side-by-side on Z-axes of miniature 3D printers or small XYZ platforms, maximizing lateral space savings.

D. B-Class Universal Interchangeability As a standard pairing group product, Group B blocks offer stable dimensional consistency, suitable for the assembly and repair replacement of most general automation equipment.

4. Technical Specifications

Please strictly note the dimensional differences from the Flange type:

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

• Block Width (W): 34 mm (Flange type is 47mm).

• Assembly Height (H): 28 mm (Total height of Block + Rail).

  • Important Contrast: Flange types (F1N) are typically 24mm high, while Square types (BK) are 28mm. You must measure the height of your old block before purchasing.

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

  • Feature: Square hole pattern.

• Mounting Hole Type: 4 x M4 threaded blind holes.

  • Installation: Screws pass through the mounting plate from above and thread down into the block.

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

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

5. Target Applications

The LSH15BK-HN-N-B-AM6 is suitable for miniaturized equipment requiring convenient maintenance:

• 3D Printers (CoreXY/Voron): X/Y axis guidance; the AM6 interface facilitates connection to automatic oil tubes.

• Desktop Robotic Arms: Linear motion for joint sections.

• Small Dispensing Machines: Densely arranged multi-head dispensing modules (due to the narrow width).

• Medical/Biochemical Instruments: Vertical movement axes (Z-axis) for test tube grippers.

• Replacement Upgrade: Replaces HIWIN HGH15CA or THK HSR15, with the added benefit of upgraded lubrication convenience.

6. Final Checklist Before Purchase

The 15mm specification is prone to errors regarding height and hole spacing. Please measure:

1. Measure Total Height: When the block is on the rail, the total height should be 28mm. (If it is 24mm, that is a Flange type or Low Assembly type; this model will not fit).

2. Measure Width: The block width should be 34mm. (If it is 47mm, that is the Flange type with "wings").

3. Check the Side: Confirm if there is a protruding metal adapter (AM6); this is key to identifying this high-spec model.

4. Confirm Code: Does your old block or requirement drawing specify Group B or B? (If it specifies Group D, purchasing Group D is recommended; however, if there are no special requirements, Group B is generally interchangeable).
