HTD 8M-85 Timing Pulley Configuration Overview<\/h2>\n<\/div>\n

8M-85 HTD Timing Pulley<\/strong> is a 8 mm pitch synchronous pulley family with a nominal belt-face reference of 85 in the catalogue naming system. This page treats the series as a configurable industrial component rather than a single fixed SKU. Tooth count changes pulley diameter and may also change hub, flange, material or mounting details, so the order must be tied to a specific catalogue row or an approved drawing.<\/p>\n

For procurement, begin with the complete belt designation and confirm that the mating belt uses the same HTD 8M profile. Pitch alone is not a safe interchange rule for every curvilinear belt family. After profile confirmation, select tooth count and working width, then review the shaft interface, hub projection, flange arrangement and available material. This sequence reduces the common replacement error of matching only outside diameter while overlooking the tooth system or mounting geometry.<\/p>\n

The straight-bore construction shown for this family is intended for positive synchronous power transmission. Typical enquiries come from machine tools, conveyors and higher-duty industrial motion. Actual suitability depends on speed, transmitted load, center distance, belt construction, alignment, environment and shaft support. Those duty inputs should be supplied for a new drive or when an existing machine has recurring belt-tracking or wear problems.<\/p>\n<\/section>\n

8M-85 Construction and Shaft Interface<\/h2>\n

8M-85<\/strong> belongs to the 8M HTD family and this page covers straight-bore construction. The catalogue table on this page spans 22\u2013112 teeth. Construction codes visible in the table include 2F, 7F, 8. Use the exact product code with the tooth count because the hub\/flange arrangement can change inside one width series.<\/p>\n

Read the 8M-85 Dimension View Before the Table<\/h2>\n

La vue des cotes explique comment les symboles tels que Dp, De, Df, Dm, Di, F, L et les champs relatifs \u00e0 l'al\u00e9sage sont li\u00e9s au plan de construction. Utilisez le plan et la m\u00eame ligne de produit ensemble\u00a0; ne reportez pas une cote d'un autre type de construction simplement parce que le pas et le nombre de dents correspondent.<\/p>\n

For 8M-85, record the values that control installation\u2014working face, hub projection, flange envelope and shaft connection\u2014against a stable machine datum. If a finished bore, keyway or tolerance is not defined by the catalogue row, add it on the RFQ or controlled drawing instead of assuming a universal value.<\/p>\n

Where the 8M-85 Family Fits<\/h2>\n

8M-85 is part of the 8M family used for industrial synchronous drives where tooth count, construction type, bore or bush and axial installation space should be reviewed together. Application suitability is not determined by pitch alone. A new drive still needs the required speed relationship, load or torque basis, center distance, environment and service conditions before the pulley row can be finalized.<\/p>\n

Pour un remplacement, le point de d\u00e9part le plus s\u00fbr est l'identification de la courroie\/du profil existant ainsi que le nombre de dents d'origine. Modifier le nombre de dents modifie le diam\u00e8tre primitif et le rapport de transmission, tandis que modifier le syst\u00e8me de fixation peut d\u00e9placer l'alignement de la courroie ou en modifier l'acc\u00e8s lors du d\u00e9montage.<\/p>\n

Material and Construction Choices for 8M-85<\/h2>\n

Use the material and construction shown for the exact 8M-85 product code or approved drawing. Do not identify pulley material from color, surface appearance or a photograph. Where a project requests a different material, finish, hub, flange or shaft feature, treat that as a custom requirement and review its effect on dimensions and inspection before quotation.<\/p>\n

Within the 22\u2013112 teeth range, construction codes can vary. That variation is why the product code, tooth count and construction view should remain together in the order record.<\/p>\n

Installation Checks for 8M-85<\/h2>\n

Before installation, compare the new pulley with the released 8M-85 row or drawing. Verify the shaft connection, axial position, flange condition and belt line before tension is applied. The belt should enter the pulley without being forced sideways by a misaligned shaft, displaced hub or incorrect spacer arrangement.<\/p>\n

Apr\u00e8s assemblage, v\u00e9rifiez les caract\u00e9ristiques essentielles au bon fonctionnement de la machine\u00a0: fixation, alignement, rotation libre, guidage de la courroie et tout faux-rond ou position axiale sp\u00e9cifi\u00e9 sur le plan. N\u2019appliquez pas de tol\u00e9rance g\u00e9n\u00e9rique si le plan de l\u2019\u00e9quipement ou la commande d\u00e9finit une exigence diff\u00e9rente.<\/p>\n

Commandes, \u00e9chantillons et planification commerciale<\/h2>\n
\n
MOQ<\/strong><\/p>\n

Les quantit\u00e9s minimales sont d\u00e9finies en fonction du type de produit, du proc\u00e9d\u00e9 de fabrication et du montant total de la commande. Les pi\u00e8ces standard du catalogue sont g\u00e9n\u00e9ralement soumises \u00e0 des quantit\u00e9s minimales de production.<\/p>\n<\/article>\n

\u00c9chantillons<\/strong><\/p>\n

Les nouveaux clients peuvent demander de 1 \u00e0 5 \u00e9chantillons lorsque la configuration et le processus de production le permettent. Les \u00e9chantillons font l'objet d'un devis s\u00e9par\u00e9.<\/p>\n<\/article>\n

Commandes mixtes<\/strong><\/p>\n

Il est possible de combiner diff\u00e9rents mod\u00e8les de poulies. Un montant total d'environ 1\u00a0500 USD constitue g\u00e9n\u00e9ralement le seuil de r\u00e9f\u00e9rence pour les commandes de mod\u00e8les mixtes.<\/p>\n<\/article>\n

faible quantit\u00e9<\/strong><\/p>\n

Les quantit\u00e9s d'une ou deux pi\u00e8ces ne peuvent \u00eatre envisag\u00e9es que pour la validation technique ou pour r\u00e9pondre \u00e0 une exigence d'\u00e9chantillon payant qualifi\u00e9, et non pour les commandes au d\u00e9tail ; le prix unitaire est donc plus \u00e9lev\u00e9.<\/p>\n<\/article>\n

d\u00e9lai de planification<\/strong><\/p>\n

Pi\u00e8ces standard\u00a0: g\u00e9n\u00e9ralement 10 \u00e0 25 jours ouvrables. Composants sur mesure\u00a0: g\u00e9n\u00e9ralement 20 \u00e0 45 jours ouvrables. Assemblages ou \u00e9quipements connexes pour projets sp\u00e9cifiques\u00a0: 45 \u00e0 120 jours ouvrables, le cas \u00e9ch\u00e9ant. Le d\u00e9lai d\u00e9finitif est confirm\u00e9 apr\u00e8s examen des plans, des mat\u00e9riaux et des quantit\u00e9s.<\/p>\n<\/article>\n

Conditions commerciales<\/strong><\/p>\n

Les incoterms EXW, FOB, CIF et DAP sont couramment utilis\u00e9s. Les incoterms FCA, CFR, CPT, CIP et DDP peuvent \u00eatre envisag\u00e9s en fonction des exp\u00e9ditions et des destinations.<\/p>\n<\/article>\n<\/div>\n<\/div>\n
