Looking for a compact aluminum-case bevel gearbox? Let us check the KBX range and its complete model code.

Customer: What distinguishes this gearbox family?
KAYO: KBX uses an aluminum die-cast housing and spiral bevel gears. The Japanese lineup has shaft diameters of 10, 15 and 20 mm, with 1:1 and 1:2 speed ratios and L or T shaft arrangements.
Customer: Which models and specifications are listed?
KAYO: The current Japanese selection table lists 12 complete model codes. All twelve are shown below. The speed-ratio notation follows the selection table; confirm the X/Y shaft designation in the drawing. Backlash is angular, expressed in degrees (°) and arcminutes (′). Mass is in kilograms.
| Model | Speed ratio | Shaft diameter (mm) | Y-axis type | Angular backlash | Mass (kg) |
|---|---|---|---|---|---|
| KBX-101L | 1/1 | 10 | L | 16′~44′ | 0.4 |
| KBX-102L | 1/2 | 10 | L | 30′~1°23′ | 0.4 |
| KBX-151L | 1/1 | 15 | L | 10′~37′ | 1.8 |
| KBX-152L | 1/2 | 15 | L | 19′~1°09′ | 1.8 |
| KBX-201L | 1/1 | 20 | L | 8′~33′ | 3.1 |
| KBX-202L | 1/2 | 20 | L | 15′~60′ | 3.1 |
| KBX-101T | 1/1 | 10 | T | 16′~44′ | 0.5 |
| KBX-102T | 1/2 | 10 | T | 30′~1°23′ | 0.5 |
| KBX-151T | 1/1 | 15 | T | 10′~37′ | 2.2 |
| KBX-152T | 1/2 | 15 | T | 19′~1°09′ | 2.2 |
| KBX-201T | 1/1 | 20 | T | 8′~33′ | 3.4 |
| KBX-202T | 1/2 | 20 | T | 15′~60′ | 3.4 |
Customer: How should I check the load capacity?
KAYO: Use the speed-dependent performance table for the exact model. For example, the KBX-101 group at 1:1 and 50 rpm X-axis speed lists 2.35 N·m allowable X/Y-axis torque. This is a specific operating point; check torque, overhung load and thrust load together for the actual application.
Customer: What does the shaft configuration mean?
KAYO: The L type has a single Y-axis direction and the T type has two Y-axis directions. Compare the shaft drawing, rotation arrows, mounting holes and coupling clearances with your installation. Send a sketch when the required arrangement is unclear.
Customer: What are the complete model codes?
KAYO: KBX-101L, KBX-102L, KBX-151L, KBX-152L, KBX-201L, KBX-202L, KBX-101T, KBX-102T, KBX-151T, KBX-152T, KBX-201T, KBX-202T.
Customer: What should I check before installation?
KAYO: The catalog specifies grease-filled lubrication. Mount securely on a flat surface, align the coupling and confirm shaft rotation before connecting the driven equipment. Use the current catalog for mounting and operating requirements.
Customer: What details should I send for an enquiry?
KAYO: Please send the complete gearbox code, quantity, required ratio, shaft layout, input speed, operating torque, external shaft loads and mounting arrangement. We can review the specification and availability for your application.
