SPA732LW三星三角皮帶,SPA732風機皮帶三角帶根據寬度和厚度分為O、A、B、C、D、E幾種不同的型號，要分清到底是哪種型號關鍵是看厚度和寬度。不同型號的皮帶會配上相對應的皮帶輪高速三角帶：SPA型、SPB型、SPC型、SPZ型

窄形V型帶，俗稱高速三角帶
寬度為*的窄狹形，高速傳動的機帶。
節省能源，設計小型化，zui高速度40米/秒，可實現高速運轉。
耐熱、防靜電性能強。
SPZ型 帶寬9.7毫米 帶高8.0毫米 橡膠 標準型號SPZ 切片有齒型號SPZX
SPA型 帶寬12.7毫米 帶高10.0毫米 橡膠 標準型號SPA 切片有齒型號SPAX
SPB型 帶寬16.3毫米 帶高13.0毫米 橡膠 標準型號SPB 切片有齒型號SPBX
SPC型 帶寬22.0毫米 帶高18.0毫米 橡膠 標準型號SPC 切片有齒型號SPCX
切片有齒指的是皮帶兩邊采用機械切割而成，具有明顯的棱角，同時皮帶下面鑲有帶齒。

普通三角帶：M型、A型、B型、C型、D型、E型
標準V型帶，俗稱普通三角帶
應用廣泛的動力傳動帶，成本低廉、隨時可用、更換方便，尺寸穩定性良好。
M型 帶寬10.0毫米 帶高5.5毫米 橡膠 標準型號M
A型 帶寬12.5毫米 帶高9.0毫米 橡膠 標準型號A切片有齒型號AX聯組型號RA、RAX
B型 帶寬16.5毫米 帶高11.0毫米 橡膠 標準型號B切片有齒型號BX聯組型號RB、RBX
C型 帶寬22.0毫米 帶高14.0毫米 橡膠 標準型號C切片有齒型號CX聯組型號RC、RCX
D型 帶寬31.5毫米 帶高19.0毫米 橡膠 標準型號D聯組型號RD
E型 帶寬31.5毫米 帶高19.0毫米 橡膠 標準型號E聯組型號RE
切片有齒指的是皮帶兩邊采用機械切割而成，具有明顯的棱角，同時皮帶下面鑲有帶齒。
