  • Material grade such as 40Cr, 42CrMo, bronze, or customer-specified grade

Material and fit notes

Pin and bushing quotes depend heavily on material, machining tolerance, heat treatment, and surface condition.

A sample or drawing is preferred when the part is not a standard repair-kit item.

Grease grooves, oil holes, and special hardness requirements should be stated before supplier review.

Inspection points

  • Diameter and length measurement
  • Material and hardness check where required
  • Groove, hole, and chamfer position
  • Surface finish and coating condition
  • Kit packing and part mark consistency

Buyer questions

Practical answers before sending an RFQ.

Can you review custom pins and bushings without a part number?

Yes, but dimensions, drawings, sample photos, material, and application position are needed before a credible RFQ review.

Can pins and bushings be quoted as a kit?

Yes. List the machine model, linkage position, item mix, and quantity for each kit so the matching work is clear.

What information matters most for bushings?

Dimensions, material, tolerance, grease groove design, surface finish, and working position usually matter more than the product name.

Quote review

Send model, drawing, material, quantity, and destination details.

Final price, samples, lead time, payment terms, and compliance details are confirmed manually after supplier review.
