SPZ900 Metric Wedge Section V-Belt

The SPZ900 is a metric wedge (SPZ) V-belt designed for compact drives that need high power transmission in a small envelope. Built from heat- and oil-resistant compounds with polyester/aramid cord options, it delivers stable grip, low stretch, and long service life in industrial, agricultural, and HVAC applications.

Quick Specs

• Profile: SPZ (metric wedge)
• Top Width: ~10 mm (≈ 0.394″)
• Thickness/Height: ~8 mm (≈ 0.315″)
• Nominal Length: 900 mm (see note on length standards below)
• Construction: Wrapped (smooth exterior); fiber-reinforced rubber body
• Temperature Range: −30 °C to +80 °C (typ.)
• Common Uses: Fans, blowers, pumps, compressors, conveyors, machine tools, agricultural equipment

Length Standard Note

“SPZ900” typically denotes a 900 mm nominal length; some brands mark inside length (Li) while others mark pitch length (Lp). Pitch and outside lengths are typically a bit longer than Li. If you’re matching an existing belt, use the length basis printed on your current belt or the OEM manual.

Common Cross References

These are widely used equivalents for the same SPZ profile and nominal 900 mm length. Always verify the brand’s length basis (Li/Lp/La) before substituting.

Why Choose This Belt

• High power density for smaller pulley diameters
• Good efficiency and reduced slip under load
• Resists heat, oil, ozone, and abrasion
• Interchangeable across major SPZ specifications

Fit Tip

If your current belt reads XPZ instead of SPZ, it’s a cogged raw-edge version of the same profile. Many drives accept either, but verify pulley condition and guard clearances. For matched multi-belt sets, replace all belts together.
