Load Position (inches from CF)

Output Shaft Bearing Radial Load CurveBased on 18,000,000 revolution life (filled with 85W-140 oil)

A simultaneous maximum torque and maximum speed NOT recommended.Consult Heco if your application falls outside of recommended maximum RPM, torque, or radial load.

Torque RatingsModel Continuous Intermittent Peak

16, 16D 30,000 in∙lbs 2,500 ft∙lb 3,390 Nm

45,000 in∙lbs 3,750 ft∙lb 5,080 Nm

60,000 in∙lbs 5,000 ft∙lb 6,780 Nm

For maximum speed reducer life the recommended oil is SAE 85W-140 multi-grade gear oil meeting APIGL5 and API-MT1 service. Alternate oil that will provide adequate speed reducer life is SAE 90W gear oil meeting API-GL5 and API-MT1 service. These oils should be readily available at your local automotive store or lubricant dealer.

When using a Bearingless hydraulic motor or “Flow Through” lubrication, where hydraulic oil from the hydraulic motor lubricates the speed reducer, an ISO 68 hydraulic oil with EP1 additives and a minimum of 0.125% zinc anti-wear additive will provide adequate speed reducer life.

Maximum oil temperature should not exceed 160° F (71° C) for continuous operation or 180° F (82° C) for intermittent operation.

Consult Heco Gear for applications requiring use of non-petroleum based or fire retardant lubrication.

Warranty information and Parts & Service manuals (PDF format) are available at www.hecogear.com.

Application InformationTorque, speed, radial and axial load affect reducer life. Reducer life is also dependent on the duty cycle of the specific application. A duty cycle is defined by Heco as an operation beginning with start and ending with a full stop or full reversal. Duty cycle segments often consist of a number of components; starting, running and stopping are the typical components. Swing or slewing drives often consist of reversals with overrunning load components that affect speed reducer life. Starting and stopping under load will also affect reducer life.

Applications requiring simultaneous high speed and high torque operation will have reduced life. Applications requiring high speed and low torque operation may have a reduced life. Applications requiring high speed and low torque duty cycles or low speed and high torque duty cycles may have extended reducer life depending upon application specifics.

Consult Heco Gear with your duty cycle information and our design engineers can estimate speed reducer life for your specific application, however, testing the speed reducer in the specific application by the customer is recommended to determine actual life.

Oil RecommendationFor maximum speed reducer life, the recommended oil is SAE 85W-140 multi-grade gear oil meeting API-GL5 and API-MT1 service. Alternate oil that will provide adequate speed reducer life is SAE 90W gear oil meeting API-GL5 and API-MT1 service. These oils should be readily available at your local automotive store or lubricant dealer.

When using a bearingless hydraulic motor or “Flow Through” lubrication, where hydraulic oil from the hydraulic motor lubricates the speed reducer, an ISO 68 hydraulic oil with EP1 additives and a minimum of 0.125% zinc anti-wear additive will provide adequate speed reducer life.

Maximum oil temperature should not exceed 160° F (71° C) for continuous operation or 180° F (82° C) for intermittent operation.

Consult Heco Gear for applications requiring use of non-petroleum based or fire retardant lubrication.
