European Standard SPB180 3-Groove Wide-Section Heavy-Duty V-Belt Pulley, for Mining Crushers and Vibrating Screens

The SPB180-3-2517 pulley is a fundamental transmission component designed for medium-to-heavy loads and high-impact operating conditions. Compared with the SPA series, the SPB groove profile has a wider top section (16.3mm) and deeper grooves. Combined with the 63mm-wide rim, it delivers outstanding stability and resistance to deformation when transmitting high power.

Model SPB180-3-2517 (3 grooves)
Material HT250 gray cast iron (GG25)
Standards DIN2211 / ISO4183
Groove profile SPB narrow V-belt (wide-section series)
Number of grooves 3
Pitch diameter 180mm
Outside diameter 187mm
Rim width 63mm (wide-rim design)
Overall hub width 45mm
Matching taper bush 2517, standard bore range 20~65mm
Surface treatment Black phosphating / electrophoretic coating for rust protection
Process Casting + CNC precision turning + dynamic balancing
Compatible belts SPB narrow V-belts

1. Wide-section deep-groove design, anti-vibration under heavy loads: The SPB groove profile is purpose-built to carry higher torque. The CNC-turned deep grooves hold the belts firmly, effectively suppressing belt rolling and flutter inside the groove even when all three belts run at full load.
2. Wide rim + thick-wall structure, high rigidity: The rim is 63mm wide and the hub wall is uniform and thick. This heavy-duty structure keeps the pulley from deforming under sudden shock loads (such as a crusher jam) and greatly extends service life.
3. Three-groove redundancy for continuous production: The 3-groove parallel layout shares the load across belts. If one belt breaks unexpectedly, the remaining two can keep the equipment running for a short time, buying valuable time to schedule planned downtime.
4. Quick-release taper bush and heavy-duty rust protection: The large 2517 taper bush provides strong shaft clamping force and can be installed and removed without heating or hammering. Black phosphating or black electrophoretic coating is available to meet the rust-protection needs of humid, dusty workshops.

- A "power-type" pulley built for high loads: When an SPA pulley cannot meet the torque demand, the SPB180 is the ideal upgrade.
- Lower maintenance costs for heavy equipment: Strong taper-bush clamping plus single-belt-failure redundancy greatly reduce unplanned downtime caused by drive-system faults.
- Wide-rim wrap-around design: Extends the wear cycle of the belt sidewalls and reduces premature belt scrapping.

- Mining and building materials: Heavy-duty vibrating screens, crushers, and cement-plant conveyor drives.
- Heavy-duty fans and pumps: High-torque power input for large industrial induced-draft fans and slurry pumps.
- Construction and agricultural machinery: Core drive points of high-horsepower tractors and harvesters.
- General heavy industry: Large woodworking machines, chemical agitators, and air compressor main units.
