NM128 technical data<\/h2>\n<\/div>\n

NM128 doubles the nominal torque of NM112 to 140 N.m and increases maximum bore to 55 mm. It is a practical candidate for machinery where shaft diameter and starting load have moved beyond the lighter NM sizes.<\/p>\n<\/div>\n

Uygunluk ve i\u015fleme kontrolleri<\/h2>\n

The coupling envelope is 128 mm in diameter with a 70 mm length. Measure the actual space between surrounding structures rather than relying on a previous model number, because a larger hub can solve a bore issue while creating a guard-clearance problem.<\/p>\n<\/div>\n

Bu beden nereye uyar?<\/h2>\n

For mixers, conveyors, pumps and similar industrial drives, use the 140 N.m nominal rating as the first screen and describe how the machine starts. A loaded conveyor start and a steady pump at the same running power do not impose the same transient conditions.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Hizalama ve montaj<\/h2>\n

The stated separation for NM128 is 3.5 +\/- 1.0 mm. Keep radial misalignment within 0.07 mm and angular misalignment within 2.5 degrees, then inspect the elastomer after commissioning if the installation previously showed uneven wear.<\/p>\n

Prepare the NM128 RFQ<\/h2>\n

A useful NM128 quotation request combines mechanical interface and duty data: both bores, both keyways, rpm, torque or motor power, driven machine, quantity and any controlled fit. Attach the shaft drawing when shoulders or unusual keys affect machining.<\/p>\n

When 55 mm bore capacity or 140 N.m torque is insufficient, review NM148. When the application is comfortably below those limits, NM112 may provide a smaller diameter and shorter assembly.<\/p>\n
