Heavy Duty Rock Solid Four Groove Cast Iron V Belt Pulley Built Like A Tank For SPB Profile Drives With A 560 Mm Pitch Diameter And A Roomy 112 Mm Hub Bore

Four groove cast iron V belt pulley for heavy duty machinery
✔️ SPB drive pulley packs four grooves and measures 560 mm pitch

This single unit cast iron belt sheave transfers rotational force from electric motors to driven shafts on factory conveyors, rock crushers, and wood chippers. The rigid housing resists flexing under constant load while locking SPB v-belts in precise alignment for smooth power transmission.

✅ Four groove layout handles multiple SPB belts for higher torque carry
✅ Thick cast iron body absorbs impact shock and deadens motor hum
✅ 560 millimeter pitch circle holds steady ratio across heavy duty cycles
✅ 112 millimeter hub bore slides straight onto standard keyed drive shafts

💡 What makes a cast iron v belt pulley reliable for industrial motors?
Solid metal housings stay handy when your plant runs double shifts because the dense walls dump heat fast and keep sprocket teeth meshed tight.
- Four groove geometry tracks v-belts smoothly even during startup surges
- Exact 560mm pitch dimension locks belt speed ratio without slip or drift
- Wide 112mm opening mates directly with common keyed shafts in minutes
- Reinforced web ribs brace against whip when tension rods stretch out
