Jointed Rail Ordering Code
Example: LSD 15 H N 1X3920 T 3900 T 3920 A H ...
Used when the required rail length exceeds the maximum standard single-piece length (approx. 4000mm), requiring multiple rails to be jointed.
Key Differences in Ordering
| Code Pos. | Item | Description |
|---|---|---|
| 7 | 1st Rail Length | Length of the first rail segment (e.g., 3920). |
| 8 | Joint Mark 1 | T: Joint mark for 1st connection. |
| 9 | 2nd Rail Length | Length of the second rail segment (e.g., 3900). |
| 10 | Joint Mark 2 | T: Joint mark for 2nd connection (if applicable). |
| 11 | 3rd Rail Length | Length of the third rail segment (e.g., 3920). |
Note: The rest of the code (Preload, Accuracy, Grease, etc.) follows the standard sequence after the rail definition.
Individual Component Ordering
1. Block Only Ordering (BK)
Example: LSD 15 BK-H N - H - D - AM6 - DD
| Item | Options |
|---|---|
| Model | LSD + Width (15/20/25/30/35) + BK (Block) |
| Surface | -Blank: Natural, -H: Black Chrome (Note: suffix position may vary) |
| Type | N: Standard Length, S: Short |
| Shape | H: Square, F1/F2/F3: Flange |
| Accuracy | N: Normal, H: High, P: Precision |
| Assembly | D, E, F... (See Assembly Table below) |
| Grease | Optional (e.g., AM6) |
| Dust | Optional (e.g., DD, ZZ) |
2. Rail Only Ordering (RL)
Example: LSD 15 RL X 220 - S20 - H - D - T
| Item | Options |
|---|---|
| Model | LSD + Width + RL (Rail) |
| Joint | X: Jointed, Blank: Single piece |
| Length | Rail Length (mm) |
| End Dist. | S: Standard, Value: Custom (e.g., S20) |
| Accuracy | N: Normal, H: High |
| Assembly | D, E (See Assembly Table below) |
| Mounting | Blank: Upper Lock, T: Lower Lock |
3. Assembly Code Matching Table (组配表)
Used when ordering blocks and rails separately to ensure correct fit.
| Accuracy | Preload Class | ||
|---|---|---|---|
| No Preload (A) | Light Preload (B) | Medium Preload (C) | |
| Normal (N) | Code: D | Code: D | Code: SB |
| High (H) | Code: E | Code: C | Code: SA |
| Precision (P) | - | Code: E | Code: SB |
