How do I request a quotation for teeth and adapters, and how fast will I get a reply?

Send the casting number from an old tooth or adapter, or clear photos of the tooth nose and adapter seat together with the machine model and serial number, the quantity per line, and the destination port through the contact page of Guangzhou Shenyue Machinery Technology Co., Ltd. Quotations normally come back within 24 hours, with teeth, adapters, pins and complete sets quoted by grade.

Can I mix teeth and adapters from different makers?

Not safely. Tooth and adapter noses are matched systems — the seat angle, the pin slot and the nose taper are designed together. A tooth from one maker on an adapter from another can fit loosely, wear fast, or drop off in the bucket. Order teeth and adapters as a matched system, and replace pins and locks with every change.

Which tooth style should I choose for general duty?

Standard general-purpose teeth suit mixed digging; rock or twin-tiger teeth suit penetration in hard, rocky ground; wide flare and heavy-duty styles suit loading and abrasive wear. Most fleets run standard teeth and switch styles seasonally — tell us your material and duty cycle and we will quote the style that fits the work.

Bucket Teeth and Adapters Buying Guide: Styles, Systems and the Ordering Details That Matter

Bucket teeth are the first part of an excavator to touch the ground and the first part to wear out — which makes them the highest-volume wear item in the ground-engaging trade, and one of the most frequently mis-shipped. The reason is that teeth look alike: a photo of a pointed lump of steel does not tell you its pin system, its adapter match, or its steel grade, and a set that fits badly wears twice as fast while a set that drops off can cost a day of digging. Buying teeth well is not complicated — it just needs the right identifiers. Corbay is the international export brand of Guangzhou Shenyue Machinery Technology Co., Ltd., Guangzhou, China. Teeth, adapters, pins and quick couplers are quoted from Guangzhou daily across Kobelco, Komatsu, Hitachi, Doosan, Hyundai and other makes, and this guide is the checklist we apply to every teeth order.

Tooth Styles — Match the Steel to the Ground

General purpose (standard).The all-round style for mixed soil. If you order nothing else, you order these — and most fleets should hold them as the default line.

Rock and twin-tiger.Longer, sharper penetration for hard, compacted and rocky ground. Penetration means less impact per cycle — which also protects the machine's hydraulics.

Wide-flare and heavy-duty.Wider, blunter profiles for loading, ditching and abrasive wear where the material is not the enemy — the volume of it is.

The steel matters as much as the shape.Two teeth with the same casting shape can be very different alloys. Casting numbers and named makers are the only honest identifiers — see our Kobelco part-number guide for how references are structured.

Adapter Systems — Where Teeth Orders Go Wrong

The adapter — the nose welded or cast onto the bucket lip that the tooth seats onto — comes in matched systems, and the system decides everything. Top-pin teeth lock with a vertical pin through the nose, common on many machines and simple to service. Side-pin teeth lock horizontally through the adapter, holding the tooth tight against wear. Beyond these sit the proprietary quick-change systems that let teeth swap without hammering. The failure mode is always the same: a tooth bought by shape on an adapter bought by shape. Seat angles, nose tapers and pin slot positions are designed as one system — a near-miss fit works loose, wears the nose, and turns a cheap wear item into a destroyed adapter and a welded repair. The machine makers' own parts documentation shows how ground-engaging references are numbered against machine series, which is why we anchor every quote to the casting number on your old tooth or adapter.

Wear, Rotation and Replacement Timing

Rotate before you replace.Outer teeth wear faster than centre teeth — swapping positions spreads the wear and stretches every set.

Watch the adapter nose.When the tooth wears back and starts cutting into the adapter seat, the clock is running on the adapter too. Replacing teeth on time protects the more expensive part.

Never reuse worn pins and locks.A fresh tooth on a stretched pin is how teeth end up in the crusher. Pins and locks cost little; a lost tooth costs a day.

Stock by cycle, not by crisis.Teeth are light, stackable and ship cheaply in volume, so planned stocking orders cost far less per set than crisis buys.

What We Need to Quote Your Teeth and Adapters

Five details, every enquiry: the casting number from an old tooth or adapter — or clear photos of the tooth nose, adapter seat and locking pin if the number is worn away; the machine model and serial number; the duty (digging, rock, loading) so the style fits the work; the quantity per line; and the destination port. Send those to the team at Guangzhou Shenyue Machinery Technology Co., Ltd. through the contact page and the quotation normally comes back within 24 hours — teeth, adapters, pins and complete sets quoted line by line in genuine, OEM-quality and aftermarket grades. Mixed teeth orders consolidate easily with undercarriage and filter lines into one shipment — see the parts catalog.

Bucket Teeth — FAQ

I have no casting number and the old teeth are worn smooth. Can you still quote?Yes — photos of the tooth nose, adapter seat and pin slot plus the machine model and serial identify the system in most cases. Where two systems look similar we say so honestly and ask for one measurement rather than guessing.

Do you supply quick couplers and complete GET sets?Yes — quick couplers, adapters, pins, locks and teeth are quoted as matched sets per machine, so what arrives fits together and stays together.

How do I request a quotation and how fast will I get a reply?Send the casting numbers or photos, machine model and serial, quantities and destination port via the contact page — Guangzhou Shenyue Machinery Technology Co., Ltd. normally replies within 24 hours with every grade stated on the line.

Order Teeth as a System, Not a Shape

Teeth are the cheapest steel on the machine — until the wrong ones tear an adapter off the lip. Send the casting numbers, the photos and the duty description, and the team at Guangzhou Shenyue Machinery Technology Co., Ltd. will quote the matched system, the right style for your ground, and every grade in writing.
