Selecting a circular-section rack with CP teeth? SROCP combines round-body geometry with circular pitch.

Customer: Which family should I specify?
KAYO: CP identifies circular pitch. Select a pinion with the matching CP specification; keep the pitch system explicit when requesting a quote.
Customer: Which models and sizes are shown?
KAYO: The current Japanese selection table lists 3 model codes for this group. Pitch values: CP2.5, CP5, CP10. All listed models are shown below.
| Model | Pitch | Overall length (mm) | Face width (mm) | Mass (kg) |
|---|---|---|---|---|
| SROCP2.5-500 | CP2.5 | 505 | 10 | 0.30 |
| SROCP5-500 | CP5 | 505 | 15 | 0.65 |
| SROCP10-1000 | CP10 | 1010 | 30 | 5.16 |
Customer: What should I check before installation?
KAYO: Check guide support, anti-rotation requirements and the selected CP pinion. Check tooth pitch, pressure angle, rack mounting height and pinion alignment. Confirm backlash and lubrication for the actual duty. Where sections meet, verify the joint geometry and pitch continuity.
Customer: What are the exact model numbers?
KAYO: SROCP2.5-500, SROCP5-500, SROCP10-1000.
Customer: What should I send for an enquiry?
KAYO: Please send the complete model code, quantity, required travel, mating pinion, mounting details, speed and load. We can discuss the specification and availability for your application. Confirm final dimensions and suitability against the latest manufacturer information.
