The Linear 2200-674 is a 60:1 RS gear reducer for select Linear / OSCO operator drive systems. A reducer changes motor speed into usable torque for the gate or barrier mechanism, so it is one of the major mechanical parts in the operator. When the reducer is worn or damaged, the motor may still run but the operator can become noisy, weak, jerky, or unable to move the gate consistently under load.
This part is often referenced as a 60:1 reducer gear and is commonly cross-searched with the older 2200-819 gear reducer reference. Gear reducer fitment should never be guessed by ratio alone. The mounting pattern, shaft orientation, operator family, horsepower, and drive configuration all matter.
May be used with select Linear / OSCO operator applications where the parts diagram specifies 2200-674 or the confirmed replacement path from 2200-819:
| Manufacturer | Linear / OSCO |
|---|---|
| Product Type | Gear reducer |
| Part Number | 2200-674 |
| Application | Operator drive speed reduction and torque transfer |
| Gear Ratio | 60:1 |
| Compatible Operator Type | Select Linear / OSCO commercial gate operator drive systems |
| Related Supersession | Common listings state 2200-674 replaced 2200-819 |
| Notes | Match reducer label, shaft layout, mounting pattern, and operator parts diagram |
Before replacing a reducer, confirm the gate or arm moves freely by hand where safe and appropriate. A binding gate can destroy a new reducer quickly and may make the original failure look like a reducer-only problem.
Commercial gate operator service parts should be installed with power safely disconnected and the operator secured against movement. For high-voltage wiring, moving gate hazards, or uncertain field conditions, use a qualified gate technician.
Do not replace a gear reducer based only on horsepower or ratio. Similar reducers may have different shaft layouts, mounting patterns, or operator applications.
It refers to the gear reduction ratio, reducing motor speed while increasing usable torque for the operator drive system.
Some supplier listings state that 2200-674 replaced the 2200-819 60:1 gear reducer, but the original operator and reducer layout should still be verified.
Grinding noise, oil leakage, excessive backlash, weak gate movement, slipping under load, or motor operation without proper gate travel can point to reducer wear.
No. It is only for operator models and drive assemblies that specify this reducer or a confirmed related replacement.
Yes. Chains, sprockets, bearings, couplings, brake parts, and gate movement should all be inspected to avoid damaging the new reducer.
