SPZ Wedge Belts – High‑Power Industrial Drive Belts
SPZ wedge belts are compact, high‑speed narrow V‑belts designed for reliable power transmission on small‑pulley industrial drives. With a 9.7 mm × 8 mm profile, SPZ belts deliver excellent grip, low vibration and long service life, making them ideal for fans, blowers, pumps, compressors and light‑to‑medium engineering machinery. Their narrow cross‑section allows efficient power transfer even where space is limited, helping reduce drive size while maintaining strong performance.
At Transpower Drives, we supply the full range of SPZ belt lengths from 400 mm up to 3000 mm, covering all standard pitch sizes used across the UK industry. Whether you’re replacing a single belt or maintaining a full workshop, our SPZ belts are manufactured to ISO/DIN wedge‑belt standards and built using high‑strength polyester or aramid tensile cords with heat‑ and oil‑resistant rubber compounds for dependable operation in demanding environments.
We support customers across Wellingborough, Northampton, Kettering, Corby and the wider Northamptonshire region, with same‑day collection available from our Bridle Close facility and fast UK delivery for nationwide orders. Each belt is categorised by pitch length for quick selection, and our team can cross‑reference Inside Length (IL), Outside Length (OL) or OEM part numbers to ensure you receive the correct SPZ replacement.
Whether you’re maintaining HVAC systems, workshop machinery, agricultural equipment or compact industrial drives, our SPZ wedge belts provide a durable, efficient and cost‑effective solution for everyday engineering applications.
We’ve organised the SPZ belt range into straightforward child groups so you can move through the sizes quickly and find the exact belt length without scrolling through long lists.
