What Is the J-LM10?

The J-LM10 is a self-lubricating plastic linear bushing with a 10 × 19 × 29 mm dimensional envelope.

It uses a sliding surface rather than recirculating balls, making it a useful example of when a plastic sliding bushing can be considered instead of a conventional LM10 ball bushing.

The important point is not that one type is universally better. The J-LM10 may make sense when the application values low lubrication requirements, corrosion resistance, low maintenance, or a simpler sliding mechanism — provided the actual load, speed, shaft condition, temperature, and environmental requirements are suitable.

Sliding vs. Rolling: How J-LM10 Works

A self-lubricating plastic sliding bushing uses a different motion principle from a ball bushing.

Instead of recirculating balls, the shaft slides directly against a polymer-based bearing surface. This can reduce lubrication requirements and eliminate the rolling elements entirely.

That difference can be useful in applications where:

• Regular lubrication is difficult

• Corrosion is a concern

• Dust or moisture is present

• Low maintenance is important

• Lower noise is desirable

• A rolling-element solution offers more performance than the application actually requires

This is a different engineering solution, not simply a different material.

When J-LM10 Makes Sense

The J-LM10 may be a suitable alternative when the application prioritizes:

• Reduced lubrication requirements

• Corrosion resistance

• Low maintenance

• Lower noise

• Simple sliding motion

• Operation in environments where regular lubrication is inconvenient

A conventional ball bushing may still be the better choice when the application requires higher linear speeds, high positioning precision, higher load capability, or a rolling-element design specified by the original equipment.

Typical Applications

• Linear motion systems where regular lubrication is difficult

• Equipment exposed to moisture, dust, or corrosion

• Low-maintenance or low-noise applications

• Replacement of worn linear bushings in suitable applications

• Lightweight assemblies and compact mechanisms

Actual suitability depends on the load, speed, shaft condition, temperature, and environmental requirements of the equipment.

Need to Match an Existing J-LM10 Bushing?

Don't match a linear bushing by bore size alone. A 10 mm bore does not automatically mean every 10 mm linear bushing is interchangeable.

Before ordering, check:

Bore → Outer Diameter → Length → Motion Type → Shaft → Load → Speed → Temperature → Environment

Also confirm whether the original part is sliding or rolling. Two products can share the same dimensional envelope while using completely different motion principles.

Send us any of the following:

• Existing part number

• Bore, OD, and length

• A photo

• A drawing

• A physical sample

• Equipment model

We'll check the dimensions, configuration, and application requirements to help determine whether a sliding or rolling-element bushing is the better match.

Don't have all the information? Send us whatever you have. A photo, partial dimensions, or the old part may be enough for us to start the identification.

Why Buy From EKB?

Choosing a plastic sliding bushing only makes sense when the product matches both the equipment dimensions and the actual operating requirements.

EKB helps customers check:

Dimensions → Configuration → Application → Availability

Rather than simply matching a part number, we help evaluate whether the proposed replacement is appropriate for the application.

Frequently Asked Questions

What are the J-LM10 dimensions?
The J-LM10 dimensions are:
10 mm bore × 19 mm outside diameter × 29 mm length
or approximately:
0.394" × 0.748" × 1.142".

Is J-LM10 self-lubricating?
Yes. The J-LM10 uses a self-lubricating polymer sliding surface, which can operate with little or no added lubrication under suitable conditions.

Can J-LM10 replace an LM10 ball bushing?
The J-LM10 uses the same 10 × 19 × 29 mm dimensional envelope, but it is a sliding bushing rather than a rolling-element LM10 ball bushing.
Before substitution, confirm the load, speed, shaft condition, temperature, and other application requirements.

What material is the J-LM10 made from?
The J-LM10 is an engineering plastic linear bushing with a polymer-based sliding surface.
The specific material grade should be confirmed according to your application requirements.

What if I only have the old, worn-out bushing?
That's enough to get started.
Send us a photo, the dimensions you can measure, the original marking, or the physical sample. We can begin the identification process from whatever information is available.
