| Identität / Quellensprache | LSD is a low-installation four-row ball guide. H is square; F1 is flange top mounting, F2 bottom mounting, F3 both. The official PDF is Traditional Chinese despite its /en/ URL. Size codes 15/20/25/30/35 mean actual rail widths 15/20/23/28/34 mm. |
| Getrennte Codefelder | Carriage S = short, N = standard. Preload A = no preload, B = light, C = medium. Accuracy N = ordinary, H = high, P = precision. Surface blank = untreated, BB = black coating. Positional S/N/H/P/B fields are not pneumatic magnet or port suffixes. |
| Schienengeometrie / Grenzen | One-piece rail maximum: 4040 mm for sizes 15/20/25, 4030 mm for 30/35; BB maximum 3000 mm. Hole pitch P: 60 mm for 15/20/25, 80 mm for 30/35. L = (n−1)P + S + E. Automatic matching assumes S=E; asymmetric drilling is not prohibited and requires drawing review. Rail length is customer-defined, not an enumerated cylinder stroke. |
| Grenzen des Randabstands | Size 15 standard M4: 5–55 mm; U/M3: 4–56 mm. Size 20: 6–54 mm; size 25: 7–53 mm; size 30 standard M6: 7–73 mm, U/M8: 8–72 mm; size 35: 8–72 mm. Check both S and E and the actual hole geometry. |
| Montage-Quellenkonflikt | Size 15 standard top mounting uses M4, U uses M3; size 30 standard uses M6, U uses M8. U and T bottom mounting are mutually exclusive by an explicit note, although the source examples show both. Such conflicting codes need confirmation. Carriage F1/F2/F3 and rail T/U are separate fields. |
| Schmieranschluss / Verpackung | Size 15: M4/AM6/LM6. Sizes 20/25/30/35: M6/AM8/LM8/A01/L01/SM6. AM/LM are straight/L adapters, not interchangeable thread sizes. Packaging blank = assembled, B = separate. Independent BK carriage, RL rail and L-P fitting codes require exact mating/group codes and separate confirmation. |
| Last / Schnittstellenprüfung | Dynamic C and static C0 ratings in kN, and static moments MR/MP/MY in kN·m, depend on exact carriage form and length. They are not payload kg. Confirm load directions, carriage spacing, datum height, bolt holes, preload and accuracy; no automatic capacity or interchange approval. |
| Schutz-Gesamtlängen | Standard carriage C in mm, S/N by size: 15 = 40.5/57; 20 = 46/65; 25 = 59/83; 30 = 68.5/97; 35 = 73.5/106.5. DD adds 7 mm for 15/20/25 and 8 mm for 30/35; ZZ adds 4.5 or 5 mm respectively. E lengths: 15 = 55/71.5; 20 = 62/81; 25 = 75/99; 30 = 84.5/113; 35 = 89.5/122.5. Confirm clearance. |
| Staubschutz / Testgrenzen | DD means double wipers; ZZ means wiper plus metal scraper. Source tests used wood chips, iron chips and sand, 500 km each in a configured dust rig. These are not universal life guarantees or an IP rating. Dust protection changes carriage length. |
| Selbstschmierung / Testgrenzen | E adds an oil reservoir and wick. Friction increases by 5–7 N, not percent. The LSD20 test used 30 m/min, 1200 mm stroke and ISO VG680 oil. At 1000 km it consumed 20% of the oil; estimated 4000 km+ is conditional, not a maintenance-free warranty. Confirm oil and environment. The catalogue restricts a specialized smooth configuration; confirm that configuration separately. |
| Montage / Wartung | Parallel and height tolerance tables apply to 500 mm rail spacing and specific preload cells. Bolt torque units are N·cm, not N·m. Keep bolt plugs flush and prevent misalignment. Suggested grease replenishment is every 100 km or 3–6 months; oil supply depends on size and use. Nominal combined carriage length versus rail length is only a conservative consultation screen, not a manufacturer ordering prohibition. |
