Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang CRX dari 3G Electric.
What shaft configurations are available for CRX engines?
CRX engines are available with two shaft configurations: keyway and tapped. Keyway shafts are found on models like the CRX210 (4.75mm x 45.5mm keyway) and CRX680 (6.3mm x 78mm keyway). Tapped shafts are used on models such as the CRX165, CRX225, CRX420, and CRX750, with thread sizes of 5/16-24 UNF-2B or 7/16-20 UNF-2B. The CRX1000 has a keyway of 6.3mm x 88mm. Always verify the shaft configuration against your coupling or pulley requirements before ordering.
What is the horsepower range of the CRX engine series?
The CRX engine series covers a horsepower range from 4.2 hp (CRX165) to 32 hp (CRX1000). Intermediate models include the CRX210 at 5.7 hp, CRX225 at 6 hp, CRX420 at 12 hp, CRX680 at 19.4 hp, and CRX750 at 21.4 hp. All ratings are gross torque horsepower, measured at the engine output shaft. These engines are suitable for applications requiring consistent power output in the 4 to 32 hp range.
Are CRX engines available with electric start?
Yes, several CRX engine models are available with electric start. The CRX680, CRX750, and CRX1000 all feature electric start. The remaining models—CRX165, CRX210, CRX225, and CRX420—use recoil start. Electric start models are typically used in applications where remote or automated starting is required, such as standby generators or pump systems.
What is the shaft diameter on CRX engines?
CRX engines come with three shaft diameters: 3/4 in, 1 in, and 1-1/8 in. The 3/4 in shaft is used on the CRX165, CRX210, and CRX225 models. The 1 in shaft is used on the CRX420. The 1-1/8 in shaft is used on the CRX680, CRX750, and CRX1000. Ensure your equipment's coupling or pulley bore matches the shaft diameter for proper installation.
Do all CRX engines include a muffler?
Yes, all CRX engine models listed by 3G Electric include a muffler as standard equipment. This applies to both recoil-start and electric-start models. The muffler helps reduce exhaust noise during operation, which is important for compliance with workplace noise regulations and for operator comfort.
