LME..LUU Long-Type Linear Ball Bearings
DISLAB Precision supplies LME..LUU long-type linear ball bearings for round-shaft linear-motion systems. The available range covers shaft diameters from 5 mm to 80 mm, with extended bearing lengths and model-specific load ratings for OEM, replacement and industrial sourcing requirements.

LME..LUU Long-Type Linear Bearing Overview
LME..LUU is a long-type cylindrical linear ball bearing format designed for movement along round shafts. Its extended bearing body provides a geometry option where the machine design calls for a longer cylindrical bearing rather than a shorter standard variant.
The model range shown below runs from LME5LUU through LME80LUU. Dimensions, ball rows, load ratings and weight vary by model. Confirm the shaft, housing and mounting requirements for the selected designation before ordering.
Available LME..LUU Models and Specifications
Use the supplier-confirmed dimensions and ratings below to identify a candidate model. All dimensional values are in millimeters; load ratings are in newtons and weights are in kilograms.

Specifications shown are for the LME..LUU long-type series currently offered by DISLAB Precision. Confirm the complete designation, housing requirements and operating conditions before using these values for replacement or interchange decisions.
Understanding the LME..LUU Dimensions
- dr
- Shaft / bore diameter.
- D
- Bearing outside diameter.
- L
- Overall bearing length.
- B
- Inner / main body length as specified in the supplier table.
- W
- Supplier drawing dimension associated with the end region. Use the drawing and model table for confirmation; no additional mechanical function is implied.
- D1
- Secondary diameter identified in the supplier drawing. Confirm it against the selected model drawing and housing requirements.
The dimension illustration identifies the principal symbols; it is not a substitute for the actual model values or the machine housing drawing.
Why Choose a Long-Type Linear Bearing Format?
Consider the long-type format when the machine or replacement design requires an extended cylindrical bearing body. Selection should be based on the actual dimensions, load ratings, housing and operating conditions. A longer bearing is not automatically more precise or better suited to the application than a shorter format.
For the broader configuration overview, see the LM Series linear ball bearing family. LME..LUU is the specific long-type series covered by this page; other family designations require their own model confirmation.
Housing, Shaft and Installation Considerations
- Confirm the shaft diameter, housing bore and available bearing length.
- Maintain shaft and housing alignment, and confirm the retention arrangement.
- Avoid damaging the seals or bearing body during installation.
- Confirm lubrication requirements and the installation procedure for the selected model.
- Review contamination, operating environment and motion conditions before selection.
No universal shaft tolerance or housing fit is assumed here. Supply the drawing or required fit for model-specific confirmation.

Typical Applications
LME..LUU geometry may be considered for round-shaft arrangements in automation equipment, assembly machinery, packaging systems, material handling, inspection equipment and machine tools, including designs that call for an extended cylindrical bearing body. Suitability depends on the selected model and complete machine arrangement.
Provide application and environmental requirements with the inquiry so they can be reviewed rather than inferred from the product-family name.
Replacement and Model Confirmation
A matching shaft diameter alone is not sufficient for replacement. Compare the complete designation, dr, D, L, B, W, D1, ball rows, dynamic load rating C and static load rating C₀, together with the housing, sealing arrangement and application conditions.
Dynamic and static load ratings describe different conditions and should not be treated as universal allowable machine loads. Review the bearing arrangement, load direction and operating conditions when selecting a model.
If replacing another brand, send the old bearing model, a photograph, its drawing and available housing dimensions. For broader format-selection considerations, use the KH vs LM linear bearing selection guide; this does not establish interchangeability with KH bearings.
Ordering Information
For an LME..LUU quotation, provide:
- Complete model / designation, shaft diameter and quantity.
- Application, known load conditions and housing dimensions.
- Replacement brand/model, if applicable.
- Lubrication requirements and operating environment.
- Packaging requirements and destination country.
- Any available drawing or reference specification.
Model identification and application information help confirm the proposed product before an order is placed.
