Product Overview
A mining spec rock tooth for 20-22 ton machines on pin. Intended for continuous duty in hard rock where the machine runs two or three shifts and teeth are changed on a schedule.
The tooth is cast, heat treated and machined in our own foundry. Part number LK200RC is cast on the tooth body, so the number on the part matches the number on this page and on the packing list.
Fitment Notes
pin, 20-22 ton class. For scheduled maintenance programmes we can supply in matched batches so wear stays even across the bucket.
- Machine class: 20-22 ton
- Pin diameter: pin and retainer supplied
- Jobs: mining rock
- Matching adapter, pin and retainer available in the same order

Casting Process
The tooth starts as a sand mould and ends as a machined part under the same roof. Eight stations, one batch number, so the LK200RC you receive behaves like the sample we quoted.
1. Mould shop
Patterns are checked against the drawing, then sand moulds are made and the cavity blown clean before closing.
2. Furnace
The charge is weighed by recipe, melted, and a sample is analysed for carbon, silicon, manganese, chromium and molybdenum.
3. Casting
Pouring speed and temperature are logged for each ladle so two heats of the same number behave the same way.
4. Cleaning
Gates and risers are removed, the surface is blasted, and castings with blowholes or cold shuts are scrapped on the spot.
5. Heat treatment
Furnace charts are kept for every quench and temper cycle, and hardness is checked after tempering.
6. Finish machining
Bores and faces are machined after heat treatment so no distortion is left in the fit.
7. Quality gate
Each batch is gauged, hardness tested and impact sampled before it is released to the packing line.
8. Dispatch
Goods are packed to the agreed packing list, weighed and photographed for the shipping documents.
Where It Is Used
Mining benches, hard rock quarrying and continuous production loading. The specification assumes long shifts and little patience for unplanned downtime.
Why This Tooth
Adapter Compatibility Checked
Before shipping we match the tooth to the adapter nose dimension you are running, which avoids the classic problem of a tooth that fits the pin but not the lip.
Surface Cleaned By Shot Blast
Shot blasting removes sand burn and scale, which makes the casting easy to inspect and gives paint something to grip.
Fast Answer On Fitment
Send a photo of the old tooth and the adapter nose and we will confirm the number the same working day.
Alloy Steel Billet, Not Scrap Melt
We melt clean billet and returned risers with a known analysis instead of mixed scrap, so carbon and chromium stay inside a narrow band from heat to heat.
Pin Bore Machined After Heat Treatment
Machining happens after quenching, not before, so the bore does not distort and the pin still slides in by hand months later.
One Order Covers A Mixed Fleet
Because the range follows the common mounting dimensions, a single purchase order can cover machines of several makes working on the same site.
Questions Buyers Ask
Q: Can I get matched batches?
A: Yes, tell us the number of teeth per bucket and we will pack by batch so hardness is consistent across the set.
Q: What documentation comes with it?
A: Hardness readings per batch and the batch number on the case.
Q: Is the locking arrangement standard?
A: Standard pin and retainer, supplied with the tooth.
About The Supplier
Our business is built on repeat orders from dealers who resell to end users. That means the number on the case has to match the number on the tooth, the hardness has to match the last shipment, and the delivery date has to hold. Teeth, adapters, pins, bucket wear parts and undercarriage items are all handled in house.
Fitting And Care
Replace as a full set on mining benches. Mixing new and worn teeth loads the new ones harder and shortens their life.
- Clean the adapter nose and socket before fitting, remove dirt, rust and burrs.
- Fit a new pin and retainer with every new tooth.
- Check tightness after four hours, then every fifty hours.
- Replace at about 30 percent tip wear to protect the adapter.
