Match an LRW wide miniature linear guide
AirTAC LRW official combined ordering
Helpful for Model Matching:
| Family / actual width | LRW independent widened miniature recirculating guide. Code7/9/12/15 means actual rail width14/18/24/42 mm, not7/9/12/15 mm. N standard/L long block. No LRMW model is published in these official sources. |
| Combined ordering | LRW [BB] [7/9/12/15] [N/L] [1/2] X[length] S[first margin] [A/B/C preload] [N/H/P accuracy] [optionalT bottom mount]. Blank natural finish;BB black chrome. N accuracy Normal is distinct from N standard-block code. |
| Rail pitch / maximum | Code7/9 pitch30 mm,12/15 pitch40 mm;max individual length2020 mm all. Margins min/max7/9:4–26;12/15:5–35 mm;standard S/E20/20/30/30 mm. L=(n−1)P+S+E. Prose recommends end distances larger than half pitch; explicit table permits smaller custom margins. Drawing verification remains required. Layouts with fewer than two mounting holes or limited block space require drawing review; they are not ruled out by the catalogue. |
| Joined rails / pairing | Standard joined code has first length, internalT joint mark, second length, preload, accuracy and optional bottom-mountT. Match A001/B001 serials and arrows. Source says joint count no more than2;extra needs customization, not automatic arbitrary multi-rail availability. |
| Separate group pairing | Rail groupD;7/9 blockB→medium,C→light,D→clearance;12/15 blockA→medium,B→light,D→clearance. Separate block/rail precision choices useN/H, not combinedP. Group pairing changes preload; do not promise random component interchangeability. |
| Load units / ratings | Dynamic C100B/staticC0 arekN;staticMR/MP/MY areN·m. 7N1.07/1.96;7L1.47/2.98;9N2.03/3.91;9L2.69/5.60;12N3.13/5.31;12L4.08/7.83;15N5.26/8.76;15L6.99/12.71 kN. They are ratings, not payloadkg or two-block totals. |
| Accuracy / preload | CombinedN Normal/N Normal/H High/P Precision. Height tolerance±0.04/±0.02/±0.01 mm;height variation0.03/0.015/0.007;width tolerance±0.04/±0.025/±0.015;width variation0.03/0.02/0.01. Raceway parallelism table isμm by rail-length band. A clearance/B light/C medium radial interference isμm, not accuracy. |
| Installation / torque | Mounting datum ground/fine-milled,block markings on same side. Size7/9 M3 torque iron/cast/aluminium196/127/98 N·cm;size12/15 M4 412/274/206 N·cm, notN·m. Check reference-edge heights/chamfers against own LRW drawing. |
| Lubrication / handling | Factory Shell Alvania greaseS2;same or equivalent recommended. Replenishment each100km or3–6months adjusted by actual use. Anti-rust oil is not service grease;do not mix grease. Remove block with plastic transfer rail;ball retainers do not guarantee safe rapid/oblique removal. |
| Temperature / load selection | Environment should not exceed80°C;source maximum100°C is not continuous100°C approval. Apply actual speed,impact,vibration,load,moments and safety factors. Dynamic rating reference life100km is not promised operating life. |

AirTAC LRW widened miniature recirculating linear guides. Confirm rail width, N standard or L long block, block count, rail length/hole layout, preload, accuracy and mounting. Send full code or drawing with load, moments, required travel, quantity and destination for quotation.
L means long block within LRW. LRM is a separate narrow series. Separate LRW block/rail group codes affect preload. Send installed label and drawings for confirmation.
