Combining the Z-type flange housing with K-type hollow bore output and T-type (top-entry) input, the WPKZ is the definitive choice for flange-mount shaft-mounted drives where the driven shaft passes through the gearbox output.<\/p>\n<p style=\"margin:0;\"><a href=\"\/de\/contact-us\/\" style=\"color:#1a1a5c;font-weight:bold;text-decoration:underline;\">&#9993; Request a Quote<\/a> &nbsp;|&nbsp;
