NM82 technical data<\/h2>\n<\/div>\n

NM82 sits between the compact NM67 and the larger-bore NM97. Its 32 mm maximum bore makes it relevant to many small and medium rotating-equipment interfaces where shaft fit becomes the first sizing filter.<\/p>\n<\/div>\n

Shaft interface<\/span><\/p>\n

Fit and machining checks<\/h2>\n

Check the 82 mm outside diameter, 53 mm D1 and 40 mm length against the actual machine space. A coupling can satisfy torque and still be awkward to install if the guard opening or shaft projection is limited.<\/p>\n<\/div>\n

Operating duty<\/span><\/p>\n

Where this size fits<\/h2>\n

The nominal rating is 28 N.m with a 3000 rpm speed limit. NM82 can be evaluated for pump sets, blowers and machinery with moderate continuous duty, but loaded starts and repeated cycling should be stated rather than hidden inside a generic motor-power figure.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\n
\n
\n

Alignment and assembly<\/h2>\n

Use the 3.0 +\/- 1.0 mm S value when positioning the hubs. The stated radial limit is 0.05 mm and the angular limit is 3.0 degrees; verify them after the machines are fully assembled and tightened.<\/p>\n

Prepare the NM82 RFQ<\/h2>\n

An efficient NM82 RFQ includes both bore\/keyway requirements, running speed, design torque or motor power, the driven machine and quantity. For a retrofit, add the old coupling envelope so installation space can be compared before machining.<\/p>\n

Flexible element<\/span><\/p>\n

Material and service conditions<\/h2>\n<\/div>\n

The standard NBR element provides the flexible connection for this range. If service includes oil, heat, chemicals or unusual cycling, describe that environment and request the required polymer or hardness explicitly.<\/p>\n<\/div>\n

\n
<\/span><\/p>\n

Element<\/h3>\n

State the required material or service environment; do not identify elastomer chemistry by colour alone.<\/p>\n<\/div>\n

<\/span><\/p>\n

Machining<\/h3>\n

List the driving and driven bores and keyways separately, including controlled fits where required.<\/p>\n<\/div>\n

<\/span><\/p>\n

Speed<\/h3>\n

NM82 is rated to 3000 rpm; verify actual running speed before final selection.<\/p>\n<\/div>\n

<\/span><\/p>\n

Torque<\/h3>\n

The nominal rating is 28 N.m. Describe unusual starts, reversing or shock in the enquiry.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\n
\n

Compare the nearest NM sizes<\/h2>\n

If a shaft exceeds 32 mm or the torque margin is too small, move the comparison to NM97. Where packaging is very tight, also check whether NM67 can satisfy both bore and duty.<\/p>\n

NM82 quick answers<\/h2>\n
\n
\nWhat torque and speed define NM82?<\/summary>\n
NM82 is listed at 28 N.m nominal torque with a 3000 rpm rated speed limit.<\/div>\n<\/details>\n
\nHow large can the finished bore be?<\/summary>\n
The stated maximum bore is 32 mm. Bore, keyway and fit still need to be checked together for the ordered hub.<\/div>\n<\/details>\n
\nWhat shaft data should I send?<\/summary>\n
Send the driving and driven shaft diameters, both keyways, running speed, duty, quantity and any drawing-controlled fit.<\/div>\n<\/details>\n<\/div>\n<\/section>","protected":false},"excerpt":{"rendered":"

NM82 provides 28 N.m nominal torque, up to 32 mm bore capacity and a rated speed limit of 3000 rpm. It is suited to compact pumps, fans and light machinery when torque, shaft fit, alignment and installation space are all within the model limits.<\/p>","protected":false},"featured_media":931,"template":"","class_list":["post-907","ep_nm_product","type-ep_nm_product","status-publish","has-post-thumbnail","hentry"],"_links":{"self":[{"href":"https:\/\/nm-coupling.net\/ja\/wp-json\/wp\/v2\/ep_nm_product\/907","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nm-coupling.net\/ja\/wp-json\/wp\/v2\/ep_nm_product"}],"about":[{"href":"https:\/\/nm-coupling.net\/ja\/wp-json\/wp\/v2\/types\/ep_nm_product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nm-coupling.net\/ja\/wp-json\/wp\/v2\/media\/931"}],"wp:attachment":[{"href":"https:\/\/nm-coupling.net\/ja\/wp-json\/wp\/v2\/media?parent=907"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
