Wear Bars & Cutting Edges in HB400 and HB500

Wear Bars, Cutting Edges and Weld-On Cutting Edges for Ground-Engaging Applications

Wear bars and cutting edges form the foundation of many wear components and cutting systems used in earthmoving, demolition, recycling and quarry applications. These profiles are welded onto excavator buckets, wheel loader buckets, dozer blades, grader blades and other attachments to restore worn cutting edges or create new wear-resistant working surfaces.

HB400 and HB500 Wear Steel

Different wear steel grades are used depending on the application and operating conditions. HB400 is often selected where a balance between wear resistance and fabrication characteristics is required. HB500 offers a higher hardness level and is typically used for heavily loaded cutting edges, wear bars and high-abrasion wear zones.

Available Dimensions and Profile Configurations

The range includes wear bars and cutting edges in cross-sections from 110×12 mm to 400×50 mm. Various profile widths, material thicknesses, bevel configurations and standard lengths are available. In addition to single-bevel weld-on cutting edges, selected profiles are also available with double-bevel geometry.

Standard Lengths or Custom Cut Sizes

This category primarily contains wear bars and cutting edges supplied in fixed standard lengths. For project-specific lengths, please refer to our Wear Bars & Cutting Edges Cut to Size category, where profiles can be supplied according to the required length.

Selecting the Right Profile

The correct profile should be selected based on width, thickness, length, material grade, bevel design and installation requirements. When replacing an existing wear bar or cutting edge, the dimensions of the original component should be verified. For new fabrication projects, consideration should also be given to whether the profile will serve as the primary cutting edge, a reinforcement section or an additional wear protection component.

Difference Between Weld-On and Bolt-On Cutting Edges

The products in this category are designed for welded applications. For replaceable bolt-on systems, please see our 6 Inch Bolt-On Cutting Edges and Cut-to-Size 6 Inch Bolt-On Cutting Edges categories. Machine-specific bolt-on cutting edge ranges are also available for CAT, Komatsu, Volvo and Liebherr equipment.

Additional Wear Profiles and Ground-Engaging Components

For additional wear protection and ground-engaging applications, LIS® Germany also offers Grader Blades, Bolt-On Grader Blades, V-Shape Profiles and Studded Wear Plate. Matching fasteners for bolt-on cutting edge systems are available in the Bolts & Nuts category.

Frequently Asked Questions About Wear Bars and Cutting Edges

What is a wear bar?

A wear bar is a wear-resistant steel profile used as a cutting edge, reinforcement section or wear protection component on construction equipment and attachments.

What is a weld-on cutting edge?

A weld-on cutting edge is a wear-resistant profile that is permanently welded to the base structure of a bucket, blade or attachment to form the working edge.

What is the difference between a wear bar and a cutting edge?

The terms are often used interchangeably in the construction equipment industry. A cutting edge generally refers to the working edge itself, while a wear bar may also serve as reinforcement or wear protection in non-cutting areas.

When should HB400 or HB500 be used?

HB400 is commonly selected when a balance between wear resistance and fabrication requirements is needed. HB500 is typically used for more demanding wear applications and heavily loaded cutting edges.

Are custom cut lengths available?

Yes. Custom lengths are available through the Wear Bars & Cutting Edges Cut to Size category.

Which information is required to select the correct profile?

Key selection criteria include width, thickness, length, material grade, bevel configuration, installation requirements and intended application. For bolt-on systems, hole diameter, hole spacing and bolt pattern must also be considered.
