Standard LM..UU Linear Ball Bearings

DISLAB Precision supplies standard LM..UU linear ball bearings for closed cylindrical round-shaft linear-motion systems. Current sourcing inquiries cover models from LM4UU through LM100UU for OEM, maintenance and replacement requirements.

Final model-specific dimensions must be confirmed before ordering. Technical values may vary by manufacturer; provide the complete designation, shaft size and application requirements where possible.

Standard LM..UU Linear Bearing Overview

LM..UU is the standard / short closed cylindrical LM-family linear-bearing format for guidance on round shafts. The confirmed model range covers multiple shaft sizes, with exact dimensions and load ratings specific to the selected model and supplier.

Review the bearing, housing, shaft alignment and application requirements together. For a broader configuration overview, see the LM Series linear ball bearing family.

Available Standard LM..UU Models

The following designations are supported for sourcing and quotation inquiries. “Available for inquiry” indicates quotation support; confirm availability, order quantity and delivery requirements with your inquiry.

Model availability should be confirmed at quotation. Model-specific dimensions, load ratings, materials, sealing details and operating requirements should be verified before ordering or replacement.

Principal Dimensions and Model Confirmation

The illustration below is a principal-dimension reference, rather than a model-specific manufacturer drawing. Use it to identify the dimensions to request for the selected bearing.

dr

Shaft / inner diameter.

D

Outside diameter.

L

Overall bearing length.

B / W / D1

Retaining / stop-groove-related dimensions, where applicable.

Exact dimensions should be confirmed against the selected model drawing or supplier datasheet. Groove geometry may differ between sizes. A complete supplier dimension and load-rating table has not yet been approved for this page, so request model-specific data with your quotation.

Standard LM..UU vs LM..LUU Long-Type

Standard LM..UU is the standard / short closed cylindrical format represented on this page. LM..LUU is the extended / long-type LM-family format. Overall length differs, so the complete designation and available housing space must be checked; load ratings also require model-specific confirmation.

For the extended format, see our LM..LUU long-type linear ball bearings. Treat these as separate product formats: matching shaft diameter alone does not establish replacement compatibility.

Housing, Shaft and Installation Considerations

• Verify the shaft diameter, housing bore and available installation length.
• Maintain shaft and housing alignment and confirm the retention method.
• Avoid damaging seals or the bearing body during installation.
• Confirm lubrication and installation requirements for the selected model.
• Describe contamination and the operating environment where relevant.

Use the selected model’s drawing and supplier requirements for final design and installation. Nominal dimension terminology does not establish a shaft or housing tolerance, installation force or lubricant grade.

Typical Applications

Standard LM..UU bearings may be considered for round-shaft arrangements in automation equipment, machine tools, packaging and assembly machinery, material handling, inspection equipment and industrial positioning mechanisms. Suitability depends on the selected model and complete machine arrangement.

Include the actual load conditions, motion requirements and operating environment in your inquiry so the application can be reviewed before ordering.

Replacement and Model Confirmation

A matching shaft diameter alone does not establish replacement compatibility. Compare the complete bearing designation, shaft diameter, outside diameter, overall length, housing arrangement, sealing configuration, load requirements and operating environment.

When available, send the old bearing brand and model, a photograph or drawing, and machine or housing dimensions. Confirm the proposed product against those requirements before replacing the bearing.

Ordering Information

For a standard LM..UU quotation, provide:

• Complete LM..UU model, shaft diameter and quantity.
• Application, known load condition and housing dimensions.
• Replacement brand/model, if applicable.
• Sealing and lubrication requirements.
• Operating environment and packaging requirements.
• Destination country and available drawings or reference specifications.

The complete designation and application details help confirm the proposed model and current sourcing options.
