LM…LUU long metric cylindrical family linear bearing for d = 6–60 mm. Built for round-shaft linear motion, with model-specific dimensions and load ratings selected from the supplied catalogue.
MOQ: 50 pcs. Minimum order value USD 1,500; mixed orders and trial quantities welcome.
LM...LUU is the long metric cylindrical family member of the catalogue linear-bearing range. The extended body adds support length for carriages that need more rigidity than a standard LM bushing can provide. The practical buying question is whether its envelope and mounting style match the shaft, housing and carriage already designed into the machine.
The supplied catalogue places this series on pages 43–44. The documented selection range is d = 6–60 mm. Rather than treating the series code as interchangeable with a similar-looking bushing, confirm the exact diameter family and the mounting geometry before an RFQ is released.
| Item | Documented Value | Why It Matters |
|---|---|---|
| Series | LM...LUU | Catalogue family identifier |
| Design form | Long metric cylindrical family | Mounting / envelope decision |
| Documented range | d = 6–60 mm | Use the exact model row for final dimensions |
| Key specification fields | model / dr tolerance / D tolerance / L / B / W / D1 / eccentricity / C / Co / weight | Check drawing symbols and tolerance columns |
| Source | Catalogue pp. 43–44 | Supplied bearing catalogue / outline |
Catalogue note: The source provides model-by-model tables. This import row intentionally keeps the published family limits and field structure; final dimensions, C/Co ratings and mass must be taken from the selected catalogue model rather than inferred from a neighbouring size.
Long LM bearings are used in tall carriages, vertical slides, measuring fixtures and automation axes where a short bushing would leave too little bearing span.
They can replace a pair of short bushings in some layouts, but the longer shell does not remove the need for a straight, adequately supported shaft.
Check the available axial housing length before moving from standard LM to LUU. The longer bearing may solve support-span issues but can conflict with shoulders or seals in an existing block.
Use the exact load and dimensional row for the selected bore; never estimate a long-series length by simply doubling the standard LM dimension.
Use a straight housing bore and press the shell uniformly. Misalignment across the longer contact length can create edge loading sooner than it would in a short bushing.
Inspect the full shaft travel for scoring and binding; a local high spot becomes more noticeable as the supported length increases.
