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

A vista de dimens\u00e3o explica como s\u00edmbolos como Dp, De, Df, Dm, Di, F, L e campos relacionados ao furo se relacionam com o desenho de constru\u00e7\u00e3o.

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

Para uma substitui\u00e7\u00e3o, o ponto de partida mais seguro \u00e9 a identifica\u00e7\u00e3o da correia\/perfil existente, al\u00e9m da quantidade original de dentes. Alterar a quantidade de dentes modifica o di\u00e2metro primitivo e a rela\u00e7\u00e3o de transmiss\u00e3o, enquanto alterar a constru\u00e7\u00e3o da montagem pode deslocar a linha da correia ou dificultar a remo\u00e7\u00e3o.<\/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

Ap\u00f3s a montagem, inspecione as caracter\u00edsticas que s\u00e3o importantes para a m\u00e1quina em funcionamento \u2014 fixa\u00e7\u00e3o segura, alinhamento, rota\u00e7\u00e3o livre, guia da correia e qualquer desvio ou posi\u00e7\u00e3o axial controlada pelo desenho. N\u00e3o aplique uma toler\u00e2ncia gen\u00e9rica quando o equipamento ou o desenho do pedido definir um requisito diferente.<\/p>\n

Baixa quantidade<\/strong><\/p>\n

Quantidades de uma ou duas pe\u00e7as podem ser consideradas apenas para valida\u00e7\u00e3o de engenharia ou para atender a uma solicita\u00e7\u00e3o de amostra paga qualificada, e n\u00e3o para pedidos de varejo; o pre\u00e7o unit\u00e1rio \u00e9 correspondentemente mais alto.<\/p>\n<\/article>\n

Prazo de planejamento<\/strong><\/p>\n

Pe\u00e7as padr\u00e3o: normalmente de 10 a 25 dias \u00fateis. Componentes personalizados: normalmente de 20 a 45 dias \u00fateis. Conjuntos ou equipamentos relacionados para projetos espec\u00edficos: de 45 a 120 dias \u00fateis, quando aplic\u00e1vel. O prazo final ser\u00e1 confirmado ap\u00f3s a an\u00e1lise do desenho, dos materiais e das quantidades.<\/p>\n<\/article>\n

Termos comerciais<\/strong><\/p>\n

EXW, FOB, CIF e DAP s\u00e3o termos comumente dispon\u00edveis. FCA, CFR, CPT, CIP e DDP podem ser discutidos para remessas e destinos adequados.<\/p>\n<\/article>\n<\/div>\n<\/div>\n
