Cantilever Combined Bearing Linear Guides: selection, replacement and quotation support
Cantilevered carriages create moment loads that depend on the load offset and bearing spacing, making arrangement geometry as important as bearing catalog capacity.
Cross references and catalog data support preliminary identification. Confirm the current drawing, load capacity, tolerances and application requirements before ordering. See the industrial bearing RFQ checklist for the full data set.
Why the load offset matters
Moving the centre of gravity away from the bearing group creates a moment. The most heavily loaded rollers can see much more than the total payload divided by bearing count.
- Record load offset through the complete travel
- Maximise bearing spacing within the available structure
- Include acceleration, braking and shock
Rail and structure checks
The rails must transfer the bearing reaction into a sufficiently rigid frame. Check contact pressure, fastener or weld support, local flange deflection and torsion between parallel rails.
- Profile steel and section geometry
- Support spacing and connection stiffness
- Carriage rotation and edge contact risk
When to use adjustable bearings
Eccentric or shim-adjustable axial support can help set guide clearance after assembly, but it should not be used to correct major rail misalignment or structural distortion.
- Confirm adjustment access
- Set at the tightest travel position
- Lock and verify under controlled load

Cantilever Combined Bearing Linear Guides FAQ
How do I specify cantilever combined bearing linear guide?
Send the complete model, all suffixes, quantity, delivery country and a controlled drawing when available. Also state load, speed, environment and mounting details.
Can you verify an equivalent cantilever combined bearing linear guide?
Yes. Cross-reference numbers start the review, but interchangeability is confirmed from dimensions, internal design, adjustment, load capacity, lubrication and operating conditions.
What information is required for a quotation?
Provide the old marking, photos or drawing, critical dimensions, application, quantity and destination. Required inspection documents should be stated before quotation.
