Flangeless Graphite Bronze Wear Block, Square Self Lubricating Bronze Guide Plate JESW

Product Description:

Square graphite plugged bronze wear plate is manufactured from high-strength bronze alloy with embedded solid graphite as solid lubricant. The flat plate structure is designed for plane sliding movement. It achieves maintenance-free operation under low-speed, heavy-load conditions without continuous oil supply. Widely used for injection molds, die casting molds, automation equipment sliding guides and mechanical friction parts.

Flangeless Graphite Bronze Wear Block

This flangeless graphite bronze wear block features a square profile design, serving as a self-lubricating guide plate for linear motion and sliding applications. The flangeless configuration allows for mounting in confined spaces where flange clearance is not available. Graphite plugs are embedded in the sliding surface, providing continuous maintenance-free lubrication. The bronze substrate offers wear resistance and load capacity up to 180 N/mm². Custom dimensions, graphite patterns, and mounting hole configurations available to meet specific guide plate requirements.

Flangeless Square Profile Square guide plate without flange. Compact design for applications where flange clearance is limited or not required.
Graphite Plugged Surface Graphite plugs embedded in the sliding surface. Delivers maintenance-free lubrication for guide plate applications.
Wear Resistant Bronze Bronze substrate provides wear resistance and supports loads up to 180 N/mm². Suitable for heavy duty guide applications.
Customizable Configuration Dimensions, graphite pattern, mounting holes, and thickness adjustable to meet specific application requirements.

Frequently Asked Questions
What is the advantage of a flangeless square guide plate
A flangeless square guide plate can be mounted in confined spaces where flange clearance is not available. The square profile provides stable guidance and allows for easy alignment in multiple orientations.
How are graphite plugs distributed on the wear block surface
Graphite plugs are arranged in a grid pattern across the sliding surface. The number and spacing of plugs depend on the block dimensions, ensuring uniform lubrication across the entire guide surface.
Can mounting holes be added to the wear block
Yes. Custom mounting hole configurations can be specified, including counterbored holes, threaded holes, or through holes. Hole locations and sizes are determined based on application requirements.
What is the recommended mounting method for guide plates
Mount using bolts through the designated mounting holes. Ensure the mounting surface is flat and clean. Torque bolts to specifications to prevent distortion of the guide plate.
How to determine when to replace a wear block
Replace when surface wear exceeds 0.5mm, when graphite on the sliding surface falls below 12% of original coverage, or when the block shows signs of cracking or deformation.
