Tapered sleeve pulley SPB 112-1 1610
Tapered sleeve pulleys are mainly divided into three categories: European standard (SPZ, SPA, SPB, SPC), Chinese standard (O/A/B/C/D/E), and American standard (3V/5V/8V). Among them, European standard tapered sleeve pulleys have become the mainstream due to their strong adaptability and wide application.
Tapered sleeve pulleys are classified into three categories according to international standards, with the core differences lying in the groove size and applicable scenarios:
**European Standard Tapered Sleeve Pulleys:** Models include SPZ (narrow V-belt), SPA, SPB, and SPC. They are compatible with international standard tapered sleeves (such as 1610 and 3020), with a bore range of 15mm-180mm. Suitable for precision equipment such as air compressors and fans.
**Chinese Standard Pulleys:** Models include O, A, B, C, D, and E types, corresponding to different back widths and heights (e.g., A type 12.5×9mm). Primarily used for general mechanical transmissions.
**American Standard Pulleys:** Models include 3V, 5V, and 8V types. Linear speed requirement is ≤40m/s (steel material). Commonly found in high-speed industrial equipment.
Examples of specific European standard tapered sleeve pulley models (based on mainstream products):
SPB Series: Such as SPB630-2/3/4/5/6/8 (2-8 grooves), SPB300-3-3020 (50mm bore), compatible with tapered sleeve models 3020/5050, suitable for textile machinery and air compressors.
SPA Series: Such as SPA95-1-1210 (1 groove), SPA100-03 (42mm inner diameter), tapered sleeve model 1610, mostly used in small motors and fans.
Customized Models: Such as SPC475-8-5050 (8 grooves), SPB-425-5-3525 (5 grooves), supporting non-standard bore customization.
