iglide® J4 - round bar
iglide® J4 – round bar
iglide® J4 is a cost-efficient, low-wear material for high-volume production. It features low moisture absorption, dry-running operation, and low coefficients of friction for smooth motion in everyday mechanisms at low to medium loads.
When to use it: For economical, high-volume parts where clean running, low friction and basic media resistance are needed.
When not to use it: For higher temperatures consider J350; for maximum wear life under heavier loads consider W300.
Industry/Application Areas
- High-volume guides and sliders
- Consumer and appliance mechanisms
- General machine components
igus® bar stock materials enable fast, flexible creation of custom components with standard tools or CNC machining. All iglide® bar stocks are self-lubricating and maintenance free, ideal for prototypes, low-volume runs, and geometries outside standard parts. igus® can also machine custom parts from bar stock with quick turnaround.
When to use bar stock:
- No matching size in the iglide® catalog
- Small quantities or special dimensions
- Tribo-optimized plastic needed for low friction and wear on a chosen counterface
- High compressive strength or elasticity required
- Rapid prototypes or design iterations
- Nonstandard or complex geometries
When not to use bar stock:
- A standard iglide® catalog bearing fits
- Very large volumes of one geometry (use standard parts or molding)
- Tribo properties not required and a non-tribo plastic suffices
- The full catalog of semi-finished products is available in the Downloads tab.
Note: Our bar stock is manufactured with excess dimensions.
