NM148 technical data<\/h2>\n<\/div>\n

NM148 carries 280 N.m nominal torque and allows up to a 65 mm bore while retaining the 3000 rpm speed class. It is often the point where buyers should treat the coupling as a significant machine interface rather than a small accessory.<\/p>\n<\/div>\n

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

Fit and machining checks<\/h2>\n

The 148 mm outside diameter, 107 mm D1 and 80 mm length need to be compared with guards, supports and shaft projections. Large finished bores should be quoted with their keyway and fit so the remaining hub geometry is considered before production.<\/p>\n<\/div>\n

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

Where this size fits<\/h2>\n

Use NM148 for initial review of higher-load pumps, mixers, conveyors and process machinery when the operating torque stays within the model rating. Report loaded starts, reversing or jams separately because transient duty may control the final selection.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\n
\n
\n

Alignment and assembly<\/h2>\n

Set the hubs to S 3.5 +\/- 1.0 mm. The stated radial limit is 0.07 mm and the angular limit is 2.0 degrees. If repeated elastomer wear appears, inspect alignment and hub movement rather than treating the ring as the only maintenance item.<\/p>\n

Prepare the NM148 RFQ<\/h2>\n

For an NM148 order, include shaft diameters and keyways, running rpm, design torque or motor power, starting conditions and quantity. A machine drawing is particularly useful when the requested bore is close to 65 mm.<\/p>\n

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

The normal element material is NBR. For demanding environments, specify temperature and oil or chemical contact plus any requested alternative material or hardness in the commercial enquiry.<\/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

Hastighet<\/h3>\n

NM148 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 280 N.m. Describe unusual starts, reversing or shock in the enquiry.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\n
\n
\n

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

If the application needs more than 280 N.m or a bore larger than 65 mm, compare NM168. If duty and bore are lower, NM128 can be checked to reduce overall diameter and length.<\/p>\n

NM148 quick answers<\/h2>\n
\n
\nWhat torque and speed define NM148?<\/summary>\n
NM148 is listed at 280 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 65 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":"

NM148 provides 280 N.m nominal torque, up to 65 mm bore capacity and a rated speed limit of 3000 rpm. It is suited to mid-range pumps, blowers, mixers and machinery when torque, shaft fit, alignment and installation space are all within the model limits.<\/p>","protected":false},"featured_media":935,"template":"","class_list":["post-911","ep_nm_product","type-ep_nm_product","status-publish","has-post-thumbnail","hentry"],"_links":{"self":[{"href":"https:\/\/nm-coupling.net\/sv\/wp-json\/wp\/v2\/ep_nm_product\/911","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nm-coupling.net\/sv\/wp-json\/wp\/v2\/ep_nm_product"}],"about":[{"href":"https:\/\/nm-coupling.net\/sv\/wp-json\/wp\/v2\/types\/ep_nm_product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nm-coupling.net\/sv\/wp-json\/wp\/v2\/media\/935"}],"wp:attachment":[{"href":"https:\/\/nm-coupling.net\/sv\/wp-json\/wp\/v2\/media?parent=911"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
