Material and fit notes

Crawler undercarriage part quotes depend on profile, roller size, material, heat treatment, hardness, hole position, and batch quantity.

Similar track shoes, support rollers, and lugs can look alike but fail to match because of bolt pattern, contact face, shaft detail, or crawler position differences.

When the part is worn, measured dimensions and installed-position photos help identify the original shape before review.

Inspection points

Profile, width, height, and contact surface measurement
Bolt-hole and mounting face position check
Material and hardness checkpoint where required
Surface burr, edge, and heat-treatment condition
Part mark, sample approval, and export packing

Buyer questions

Practical answers before sending an RFQ.

Can shear lugs or track blocks be quoted from photos?

Photos help start the review, but drawings, dimensions, material, hole positions, and quantity are needed for a reliable quotation.

Are track shoe blocks standard catalog parts?

Some can be matched by model, but many crawler wear blocks require drawing-based or sample-based review because fit details differ.

What information reduces mismatch risk most?

Installed position, profile dimensions, bolt pattern, material, hardness, and worn sample photos usually reduce the largest risks.
