Does the drive require a special shaft angle? SAM is the angular miter family on the KHK page.
Customer: What distinguishes this family?
KAYO: SAM is listed as angular miter gears in the KHK range. The manufacturer identifies the material as S45C. The angular series requires the shaft angle to be specified explicitly.
Customer: Which sizes are listed?
KAYO: The current Japanese selection table shows 12 model codes. Modules: 1.5, 2, 2.5, 3. Tooth counts: 20. Representative dimensions are shown below, followed by the complete model list. Mass is stated in kilograms.
| Model | Module | Teeth | Outside diameter (mm) | Mass (kg) |
|---|---|---|---|---|
| SAM1.5-20045 | 1.5 | 20 | 32.77 | 0.067 |
| SAM3-20045 | 3 | 20 | 65.54 | 0.55 |
| SAM2.5-20060 | 2.5 | 20 | 54.33 | 0.27 |
| SAM2-20120 | 2 | 20 | 42 | 0.16 |
| SAM3-20120 | 3 | 20 | 63 | 0.53 |
Customer: How should I select the mating gear?
KAYO: Confirm the required shaft angle against the full SAM code and drawing; do not assume a standard right-angle mounting. Module and tooth count are only part of the selection; the tooth system and assembly geometry must also agree. Use the manufacturer mating guidance for the exact family.
Customer: What are the exact model numbers?
KAYO: SAM1.5-20045, SAM2-20045, SAM2.5-20045, SAM3-20045, SAM1.5-20060, SAM2-20060, SAM2.5-20060, SAM3-20060, SAM1.5-20120, SAM2-20120, SAM2.5-20120, SAM3-20120.
Customer: What should I check before installation?
KAYO: Confirm mounting distance, shaft alignment, bearing support and backlash. Check the contact pattern during assembly and choose lubrication suited to the selected material and operating conditions. Evaluate the load rating against the actual speed and duty.
Customer: What should I send for an enquiry?
KAYO: Please share the complete model code, quantity, mating gear, shaft angle, bore and keyway requirements, operating speed and load. We can discuss the specification and availability for your application.
