Looking for a cast-iron-case bevel gearbox? Let us check the CBX range and its complete model code.
Customer: What distinguishes this gearbox family?
KAYO: CBX uses a cast iron housing. The Japanese lineup has shaft diameters of 19, 25, 32 and 40 mm, with 1:1 and 1:2 speed ratios. Its model suffix also specifies the shaft arrangement, so retain the complete L or T and letter code.
Customer: Which models and specifications are listed?
KAYO: The current Japanese selection table lists 192 complete model codes. Representative models 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.

| CBX-402TA | 1/2 | 40 | T | 15′～37′ | 34 |
Customer: How should I check the load capacity?
KAYO: Use the performance table for the exact model and X-axis speed. For example, the CBX-191 group at 1:1 and 50 rpm X-axis speed lists 37.2 N·m allowable X/Y-axis torque. Confirm the actual torque, overhung load and thrust load rather than treating one catalog rating as a universal limit.
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 should I check before installation?
KAYO: The catalog specifies oil lubrication. Confirm lubricant quantity and installation requirements for the selected size, then check alignment, rotation direction and coupling clearance. 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.
