WPA Configuration and Selection
WPA is the basic foot-mounted model in the WP worm gearbox family. Its robust base mounting and motor-flange dimensional options make it suitable for industrial machinery that needs stable right-angle speed reduction.
When is WPA the appropriate configuration?
Use WPA when the machine layout requires a foot-mounted reducer and the listed motor-flange and output-shaft dimensions match the drive system.
How should the correct size be confirmed?
Compare motor power, reduction ratio, output shaft, mounting-hole dimensions, weight, and available installation space with the table. Load conditions and operating hours should also be provided.
Can ZPGear confirm a replacement model?
Yes. Send the existing nameplate, dimensional drawing or measured interfaces, motor data, mounting position, and application details for comparison.
Explore related worm gearboxes or contact ZPGear with the required ratio, motor power, mounting position, and output-shaft dimensions for model confirmation.
