Temperature and speed limits, lubricant compatibility, and the bore range this cage is offered across.
Pressed Steel Cage LM Series Linear Ball Bushings are made from low-carbon sheet steel, two-piece riveted or ribbon type, rolling-element guided. Corrosion behavior: as the rings — it relies on the lubricant and the seals. The material is magnetic, and the usable service range is not the limiting element; the lubricant and the ring heat stabilization decide. In practice this material is the standard cage of volume bearing production: light, cheap, tolerant of temperature and unaffected by the oils that age a polymer cage.

Property figures are typical for the material. In an assembled bearing the lubricant, the seals and the cage frequently reach their limits before the material does, so check all four against the duty. Material certification is available on request for production orders.
Pressed Steel Cage LM Series Linear Ball Bushings are dimensioned to JIS B 1516 / ISO 10285 exactly as the standard version is: the material changes the properties, never the envelope. What it does change — as the rings — it relies on the lubricant and the seals, magnetic and the service range not the limiting element; the lubricant and the ring heat stabilization decide — is set out below with the full size chart.
Why Pressed Steel Cage for LM Series Linear Ball Bushings
The standard cage of volume bearing production: light, cheap, tolerant of temperature and unaffected by the oils that age a polymer cage. In a lm series linear ball bushings it is the cage, which spaces the rolling elements and keeps them from touching each other.
Pressed from sheet and guided by the rolling elements, it adds almost no mass and almost no cost, tolerates a wide temperature range, and is unaffected by lubricant chemistry. It is the default cage of the standard bearing ranges for good reasons.

Corrosion characteristic

Service Limits
It is a light-duty cage: it is guided by the rolling elements and it is not intended for heavy vibration, high acceleration or sustained very high speed, which is where the machined brass cage takes over. In a heavily shocked application, cage damage rather than raceway fatigue is what ends the bearing.
Alternatives and When to Switch
Polyamide where quiet running and low friction matter and the temperature is moderate; machined brass where speed, shock or lubricant chemistry rules both of the others out.

Other ways to specify the LM Series Linear Ball Bushings
Customize the parameters below — every spec field is editable, and the drawing redraws to match the values you choose. Changing the designation snaps the other fields to that size's standard values; you can then override any individual value.
Sends the selected values to the quote form below.

Where these dimensions are actually made
Ring forging, heat treatment, raceway grinding and superfinishing all happen under one roof, so a bore tolerance and a clearance group are set by processes we control and can evidence, not by whichever supplier had stock.

Frequently Asked Questions
How do I know which cage a bearing has?
From the suffix in the designation. The conventions differ between makers, but a bearing without a cage suffix normally has the standard pressed steel cage, and the polyamide and machined brass alternatives are always marked. Where the cage matters to the duty, state it on the order rather than assuming.
Are Pressed Steel Cage LM Series Linear Ball Bushings magnetic?
Pressed Steel Cage is magnetic.
What temperature can Pressed Steel Cage LM Series Linear Ball Bushings run at?
The usable range for the material is not the limiting element; the lubricant and the ring heat stabilization decide. In an assembled bearing the lubricant, the seals and the cage frequently give out before the material does, so check all four against the duty.
What corrosion resistance does Pressed Steel Cage give?
Corrosion behavior: as the rings — it relies on the lubricant and the seals.
