QE & QM Series Tool Model Numbering System
When an application calls for straight, in-line fixtured spindles, the user can choose between QE or QM spindles.
As a guideline, QE spindles are recommended for normal duty applications that require very high rundownspeeds and where there is a moderate cycle rate. They are suitable for most industrial applications.
QM spindles are recommended for heavy duty applications that involve high cycle rates or installation on automatic stations. They offer a maximum durability and the most robust solution for such applications.
The Ingersoll Rand series of QE-DC electric tools uses a ‘smart’ numbering system to describe the tool and its features.
- The first 3 digits in the numbering system describe the tool series by motor size. There are 3 basic sizes:
- QE4
- QE6
- QE8
- The next digit describes the body style. There are 6 different styles:
- Angle
- In-line
- Offset
- Pistol
- Push-tostart
- Motor
- (which is an in-line tool that has no output spindle but can be used for adaptation for special attachments)
- (which is an in-line tool that has no output spindle but can be used for adaptation for special attachments)
- It is important to note that not all 3 series of tools have all 6 styles available.
- The next digit describes the method of tool start activation. There are 4 manual methods:
- Trigger
- Lever
- Extended lever
- Push-to-start
- Remote start
- (where the start signal is activated from an external source)
- The following 3 digits specify the tool’s maximum torque capacity in Nm.
- Tools that have a maximum torque capacity of less than 100Nm have a 0 as their first digit.
- The next digit describes the method of mounting or fixturing the tool. There are 5 methods available depending on the model type:
- Standard gear case
- (which has no mounting method)
- (which has no mounting method)
- integrated flange
- 2 styles of splined bolt-on mounting plates
- mounting plate with an integral torque reaction bar
- Standard gear case
- The final 5 digits describe the output spindle. The first 2 digits of this group describe the spindle type and size, the next digit the drive type and the last 2 digits the drive size.
The Ingersoll Rand series of QM-DC electric tools uses a ‘smart’ numbering system to describe the tool and its features.
- The first 3 digits in the numbering system describe the tool series by motor size. There are 4 basic sizes:
- QM3
- QM5
- QM7
- QM9
- The next digit describes the body style. There are 2 different styles:
- Straight
- Motor
- (The power unit is an in-line tool that has no output spindle but can be used for adaptation for special attachments.)
- The next digit describes the sensor options. There are 6 options:
- Transducer
- Transducer blank
- (for loosening applications where a transducer is not required)
- (for loosening applications where a transducer is not required)
- Power Unit
- (no transducer)
- Redundant Torque Transducer
- Redundant Angle Encoder
- Both Redundant Torque Transducer and Angle Encoder
- The following 3 digits specify the tool’s maximum torque capacity in Nm.
- Tools that have a maximum torque capacity of less than 100Nm have a 0 as their first digit.
- The next digit describes the spring tension in the floating spindle. There are 3 options:
- Light spring
- Heavy spring
- Solid (Locked) Spindle with no float
- Light spring
- The final 5 digits describe the output spindle. The first 2 digits of this group describe the spindle type and size, the next digit the drive type and the last 2 digits the drive size.
