EnglishWhat Is Rapid (rapidengrenagens.com.br)?
Updated
Rapid is a Brazilian gear manufacturer and precision machining shop that has operated for 51 years, according to its "Quem somos" page. It specializes in machining spur and helical gears, crowns, pinions, and worm gears up to module 2, in a wide range of profiles and materials. It works both as a contract machining service and as a manufacturer of high-complexity, high-precision parts, and it holds an ISO 9001 quality system. If you need small-to-fine-pitch gears or complex turned/ground parts made to a drawing or a sample, it is a relevant supplier to evaluate; if you need large-module gearing, its stated module 2 ceiling is the first thing to check.
What Rapid actually does
The company describes its core process as gear hobbing (fresagem por geração de dentes com fresas caracol). From a drawing or a physical sample, it develops the manufacturing process for the part. Its own product list defines the working envelope:
| Product | Stated limit / detail |
|---|---|
| Spur and helical gears | Up to module 2 |
| Worm gear sets (crown/worm) | Single or multiple starts, up to module 2 or DP 12 |
| Splined / serrated shafts | Per DIN 5480, 5481 and others |
| Timing pulleys | Types XL, T0.08 and others, up to 1/4" or 6.25 mm pitch |
| Chain sprockets | Up to 1/4" pitch, max diameter 120 mm |
| Ratchet-type gears | Listed without further limits |
| Special knurling | Straight, helical, or cross |
| Crown gears | Made by copy milling; tooth crowning equivalent to shaving |
| Special threads | Single or multiple starts, up to 4 mm pitch or 6 TPI |
| Sector gears | Listed without further limits |
| External lubrication grooves | Listed without further limits |
It also lists microgears as a capability, which fits the fine-pitch focus.
Who it serves
The stated markets are watchmaking, medical equipment, motorcycle parts, home appliances, auto parts, power tools, reducers, and various instruments. That mix points to small, precise components produced in batches rather than large industrial gearing. The company says it serves all of Brazil and also exports to Switzerland — the export claim is worth noting because it is consistent with the "Swiss quality" positioning in its header, though the page does not detail which customers or volumes are involved.
Company background and quality signals
- Founded 1975. The history section says the first machine was an imported Swiss Mikron gear milling machine, chosen to serve a market short on high-precision capacity.
- Expansion over time. Relocations in 1977 and 1982 followed machine imports and metrology investment; in 1986 it added turning and grinding so it could supply complete parts rather than gears alone.
- CNC adoption from 1994. The page frames this as a response to rising labor costs in Brazil.
- ISO 9001. Listed as its quality system, alongside a dedicated certification page in the site menu.
How to decide whether to contact them
Use Rapid as a candidate when your part is a fine-pitch gear or a complex precision component and you can supply a drawing or sample. Before requesting a quote, confirm three things against your own specification:
- Module or DP. Anything above module 2 falls outside the stated gear range; ask explicitly rather than assuming.
- Size limits where given. Sprockets are capped at 120 mm diameter and 1/4" pitch in the listing; other categories have no published limit, so state your dimensions.
- Scope. The company offers both service machining and part manufacturing, so clarify whether you are supplying blanks or expecting finished parts, including any turning, grinding, or heat treatment.
The site's menu (Home, Empresa, Produtos, Histórico, Certificação, Localização, Contato) is the practical route: the products page carries the detailed capability list, and the contact page is where to send drawings. The published material does not include pricing, lead times, or minimum order quantities, so those need to be established directly with the company.
