Frequently Asked Questions
SPZ pulleys are designed for narrower SPZ profile belts, typically used in smaller power transmission applications, whereas SPA pulleys accommodate a slightly wider belt profile for higher load capacities.
Taper bore pulleys utilize a taper lock bushing, which allows for easier installation, removal, and more precise axial positioning without the need for expensive keyway machining on every shaft.
For corrosive environments, we recommend ductile iron with zinc plating or nylon materials, as they provide superior protection against moisture and chemical exposure compared to raw cast iron.
Yes, we welcome OEM inquiries. We can manufacture V-belt pulleys according to your specific technical drawings or provided physical samples to ensure perfect integration with your machinery.
Our European standard taper bushing pulleys (SPZ, SPA, SPB, SPC) are available with configurations of up to 10 grooves to accommodate high-torque requirements.
While the SPZ is a European standard, we also offer a comprehensive range of American standard sheaves, including 3V, 5V, and 8V profiles to suit North American machinery specifications.
