When a Linear Bushing Wears Out, You Usually Don't Want to Deal With the Same Problem Again

If you're replacing a linear bushing that requires regular lubrication, or one that has problems with contamination, moisture, or maintenance access, you're probably looking for a replacement that's easier to maintain.

The J‑LM10 is a self‑lubricating plastic linear bushing with a 10 × 19 × 29 mm dimensional envelope. It's designed for linear motion applications where reduced lubrication requirements, corrosion resistance, and low‑maintenance operation are important.

The key question is simple:
Will it fit your existing housing and work for your application?

That's why we recommend checking the complete specification before ordering.

Technical Specifications

This bushing shares the 10×19×29 mm dimensional envelope commonly used for this bore size across the linear plain bearing market, including igus's RJUM‑01‑10 (DryLin‑R). The J‑LM10 is an independently manufactured product offered as a dimensionally compatible alternative — it is not manufactured, affiliated with, or endorsed by igus.

What This Bushing Is

The J‑LM10 is a self‑lubricating plastic linear bushing with a 10 mm bore, 19 mm outside diameter, and 29 mm length.

Unlike a conventional rolling‑element LM10 linear bearing, this type of bushing uses a sliding surface rather than recirculating balls. It is suited to applications where low lubrication requirements, corrosion resistance, or contamination resistance are important.

The J‑LM10 designation is also referenced as J‑LIN‑01R‑10 in some supplier and product listings. Because naming can vary between suppliers, we recommend confirming the complete dimensions and configuration before ordering.

Key Advantages

• Self‑Lubricating
  Designed to operate with little or no added lubrication under suitable operating conditions.

• Lower Maintenance Requirements
  Useful where regular grease application is difficult, inconvenient, or undesirable.

• Corrosion Resistant
  The non‑metallic bearing surface suits applications where corrosion of metal components is a concern.

• Low Noise
  Sliding polymer contact can provide quieter operation than conventional rolling‑element linear bearings in suitable applications.

• Lightweight
  The plastic composite construction reduces weight compared with many conventional metal linear bearing arrangements.

• Non‑Magnetic
  The polymer material introduces none of the magnetic properties associated with steel bearing components.

Where This Bushing Is Used

The J‑LM10 can be considered for applications such as:

• Linear motion equipment

• Automation and positioning systems

• CNC and light machine equipment

• Dusty or humid working environments

• Applications with limited lubrication access

• Equipment where corrosion resistance or low weight is important

Actual suitability depends on load, speed, shaft condition, temperature, and operating environment.

Need to Match an Existing J‑LM10 or LM10 Bushing?

This is where many replacement orders go wrong.

A 10 mm bore alone does not confirm compatibility.

Before replacing a linear bushing, check:
Bore → Outer Diameter → Length → Bearing Type → Shaft → Load → Speed → Operating Environment

The J‑LM10 has a 10 × 19 × 29 mm envelope, but it operates on a different principle than a conventional ball‑type LM10 linear bearing.

Send us any of the following:

• Existing part number

• Bore, OD, and length

• Photo

• Drawing

• Physical sample

• Equipment model

We'll check the dimensions and configuration before shipment.

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

J‑LM10 vs. Conventional LM10 Ball Bushing

Same envelope does not automatically mean same application.
These are two different motion principles that happen to share a common form factor — not a simple upgrade or downgrade of one another.

Why Buy From EKB?

Changing from a conventional metal linear bearing to a plastic sliding bushing only makes sense when the dimensions and operating requirements match.

EKB helps customers check:
Dimensions → Configuration → Application → Availability
so you don't have to guess whether a different type of linear bushing will work in your existing equipment.

Frequently Asked Questions

Does the J‑LM10 need lubrication?

The J‑LM10 is designed as a self‑lubricating sliding bushing and generally does not require regular added grease under suitable operating conditions. Actual lubrication requirements depend on the application.

Can J‑LM10 replace an LM10 ball bushing?

The J‑LM10 has the same 10 × 19 × 29 mm dimensional envelope commonly associated with LM10, but it is a sliding bushing rather than a rolling‑element bearing.
Confirm load, speed, shaft condition, temperature, and other application requirements before substitution.

What are the specified load limits for J‑LM10?

The specified values are 870 N dynamic load limit and 6,090 N static load limit.

Is J‑LM10 the same as igus's RJUM‑01‑10?

No.
J‑LM10 shares the same 10 × 19 × 29 mm dimensional envelope as igus's RJUM‑01‑10 (DryLin‑R) and is offered as a dimensionally compatible alternative, but it is an independently manufactured product and is not affiliated with or endorsed by igus.

Is J‑LM10 suitable for dusty or humid environments?

Its self‑lubricating polymer construction can be advantageous in dusty or humid environments where conventional lubricated metal components may be more difficult to maintain.
Suitability still depends on the actual operating conditions.
