Helpful for Model Matching:
| Family / construction | LSQH is an independently named quiet/caged-ball guide, not a named LSH quiet option. Four ball circuits and retained-chain circulation; X-profile groove contact layout. Source width codes15/20/25/30/35 correspond actual rail widths15/20/23/28/34mm. H square; F1 top-mount flange; F2 bottom-mount flange; F3 top/bottom flange. Size 15 H/F1, N only; others N standard or L long and H/F1/F2/F3. |
| Standard / E / surface | E end-mounted self-lubricator is a functional construction with increased block C length; no maintenance-free or unlimited-life guarantee. BB assembled guide black-chrome plating, not a different product family; block-only code uses B coating. No high-dust DD/ZZ or150°C option published here. BB rail≤3000mm, spliced total≤6000 two sections/≤9000 three, longer requires confirmation. |
| Complete assembly vs block only | Assembly: LSQH[BB][size][H/F1/F2/F3][N/L][block count]X[rail length]S[end distance][preload A/B/C/D][accuracy N/H/P]-[fitting][-B separate packing][-T bottom rail][-E]. BK block-only: LSQH[B][size]BK-[form][N/L]-[accuracy N/H]-[pairing code]-[fitting][-E]. Block-only contains no rail, length or selected assembly preload; never quote it as a complete guide. Complete assembly blank combined packaging, B separate packaging; separate packaging is not block-only. |
| Rail geometry / splice | Shared rail component prefix is explicitly LSH, not LSQH: LSH15RL... etc. Rail pitch15/20/25=60mm; 30/35=80. End distance E min/max: 15=5/55; 20=6/54; 25=7/53; 30/35=8/72mm. L=(n−1)P+S+E; installed endpoints both need confirmation. Standard endpoint15/20/25=40mm, 30/35=55mm. Max unplated rail 15/20/25=4040; 30/35=4030mm. Rail splice sections15/20/25 max12080, 30/35 max12030mm; beyond requires consultation. Symmetric end-hole layouts can be matched directly. For unequal end distances or spliced rails, send the original code and drawing for confirmation. |
| Preload / accuracy / component pairing | Assembly A no preload, B light, C medium, D heavy; D only 25/30/35. Accuracy N/H/P for complete assembly; separately ordered block/rail N/H only. Pairing codes are not assembly preload letters: rail C for15/20, D for25/30/35; block15/20 C/B/SB→assembly A/B/C; 25 C/B/SC/SF→A/B/C/D; 30/35 C/A/SD/SG→A/B/C/D. Do not equate block A with assembly A. Exact pairing uses source regional table; reconfirm paired rail/batch. |
| Fittings / grease / oil | Size 15 M4 nipple, AM6 straight M4→M6 or LM6 elbow.20–35 M6 nipple, SM6 straight nipple, A01 straight or L01 elbow M6→PT1/8, AM8 straight or LM8 elbow M6→M8. L-P fittings are accessories, not guide models. Source grease exampleGL261; oil viscosity 30–150cSt; manual oiling speed ≤60m/min. Grease replenishment reference 100km or3–6months, actual environment/use governs. Standard guidance does not imply E has no inspection requirement. |
| Dynamic/static ratings | Basic dynamic C and static C0 are kN; rated moments MR/MP/MY are kN·m, not permissible application payload. H/F1 family ratings size 15N13.8/14.9, 20N24.2/27.5, 20L28.9/36.4, 25N29.9/37.6, 25L36.6/47.5, 30N42.8/55.0, 30L52.3/70.0, 35N56.3/72.3, 35L68.6/92.6(C/C0). F2/F3 has same published listed C/C0 for corresponding sizes but different mounting dimensions; source mass/bolt/moment tables must be matched. Confirm duty cycle, load distribution, speed and life calculation rather than rate a machine by C alone. |
| E added length / test limits | H block C standard/E(mm): 15N61.5/77; 20N77/94; 20L92/109; 25N83.5/100.5; 25L104.5/121.5; 30N97.5/114.5; 30L122/139; 35N113/130; 35L140.5/157.5. Source says flange length differs, use corresponding construction drawing. Source LSQH20 E endurance trial 30m/min, 1200mm stroke, ISO VG680 synthetic hydrocarbon oil: 1000km used20%oil and estimates≥4000km; not universal service-life guarantee. Device may add 5–7N friction depending oil and condition. |
| Installation / operating limits | Source has accuracy/preload-specific mounting surface parallelism and step tables and shoulder/radius requirements; no single universal clearance value. Mounting bolt torque source unitsN·cm, not N·m. Hole plugs must not project above rail. Consult environment, cleanliness, temperature, loads and lubrication; no numeric operating-temperature/speed ceiling published for universal LSQH operation. Noise5.4dB(A) comparison is a stated source test point, not every installed machine. No clean-room rating, ISO-fit guarantee, or automatic component interchangeability inferred. |
