Helpful for Model Matching:
| Family / construction | LRM miniature recirculating ball guide, stainless rail/block, ball retainers and protective end covers. Rail width5/7/9/12/15 mm. N standard block / L long block; long block is not wide LRW and not a separate family. |
| Combined ordering | LRM [BB] [width] [N/L] [1/2 blocks] X[length] S[first-hole edge] [A/B/C preload] [H/P accuracy] [optional T bottom mount]. Blank natural finish; BB black-chrome coating, unavailable forLRM5. Top mount blank, bottom mountT. |
| Rail pitch / maximum | Width5/7/9/12/15 pitch15/15/20/25/40 mm; individual maximum495/995/1005/1005/990 mm. Source uncut-rail code for7 lists985 while specification maximum995; uncut/component codes require confirmation, not automatic equivalence. |
| Rail end layout | L=(n−1)×P+S+E. First and last margins must meet size-specific min/max:3–10/3–10/4–15/4–20/4–35 mm. Source prose says S/E should not exceed half-pitch but table standard margins include larger values; confirm the layout against the size-specific table and drawing. Hole layout and actual usable travel need drawing confirmation. Layouts with fewer than two rail holes or limited block space require drawing review; they are not ruled out by the catalogue. |
| Joined rails | Source standard butt joint allows only two rails, customer-defined lengths; more than two need customization. Match joint group/serial markings A001/B001, assembly arrows face each other. Bottom-mountT is different from internal butt-jointT. Jointed codes are preserved for technical confirmation. |
| Separate block / rail pairing | LRM5 block and rail cannot be ordered individually. Other rails use groupD. Width7/9 blockB→medium preload,C→light,D→clearance; width12/15 blockA→medium,B→light,D→clearance; not every A/B/C/D pairing is valid. Separate block/rail codes remain technical confirmation. |
| Accuracy / preload | H High / P Precision. Height tolerance±0.02/±0.01 mm; height variation0.015/0.007; width tolerance±0.025/±0.015; width variation0.02/0.01 mm. Raceway parallelism graph is μm vs rail length. A clearance/B light/C medium preload are radial interference in μm; these are not accuracy codes. |
| Load / moment | Dynamic C100B and static C0 tables are kN, static momentsMR/MP/MY are N·m; working-load formula uses N. Rated force in kN is not a payload in kg; combined loads on two blocks require moment and load-distribution calculations. 100km reference dynamic rating is not guaranteed service life. |
| Representative ratings | LRM5N C100B/C0=0.33/0.55kN;5L0.48/0.9;7N1.02/1.53;7L1.43/2.45;9N1.97/2.6;9L2.61/4.11;12N3.04/3.86;12L3.96/5.9;15N4.27/5.7;15L6.53/9.53. Match moment table and working conditions. |
| Installation / torque | Mounting datum ground or finely milled; multi-block identification lines on same side. Torque table is N·cm, not N·m: size5/7 M2 iron/cast/aluminium58.8/39.2/29.4; size9/12/15 M3 196/127/98. Correct reference-edge chamfer and height are size-specific. |
| Lubrication / handling | Factory Synergy Grease PS NO.2; same or equivalent grade recommended. Source recommends replenishment each100km or3–6months, adjust by actual use. Factory anti-rust oil alone is not service lubrication; do not mix grease. Use plastic transfer rail if separating blocks; ball retainers do not make rapid/oblique removal safe. |
| Temperature / selection | Operating environment should not exceed80°C; source also states maximum100°C, not continuous100°C approval. Confirm contamination, lubricant, impact/vibration, speed, working load and moments. Static safety factor normal1–2, impact/vibration2–3; service factors depend on speed. |

AirTAC LRM 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 LRM. LRW is a separate widened series. Separate block/rail group codes affect preload and LRM5 cannot be ordered individually. Send installed label and drawings for confirmation.
