4Pcs U-Groove POM Pulley | 6mm BORE | 30mm OD | 79kg Load Capacity

About this item

• 6MM BORE: These u-groove pulleys have a finished bore, or center hole, that is machined to a 6mm diameter to mount the pulley on a shaft of 6mm diameter. The accurate bore size ensures no wobble or offset during high-speed rotation, delivering stable running performance and effortless bolt-on replacement for most standard mounting shafts.
• 30 MM OD: 30mm outer diameter pulley body provides optimal contact area for wire rope traction and linear sliding. Balanced wheel size reduces per-unit pressure, minimizes abrasion, and extends the overall service life of both the pulley and matched cables.
• 9 MM GROOVE WIDE: Built with 5mm wide and 2.8mm deep u-groove with standard radian structure, firmly locks wire ropes in position. Effectively prevents rope slipping, derailment and friction damage, ensures smooth, safe lifting and sliding operation for long-term continuous use.
• DOUBLE SHIELDED: Pulleys with a ball bearing are easier to turn than pulleys without a bearing. Pulleys with double shielded bearings block out dust and other contaminants. These pulleys are used to assist with horizontal pulling or to guide a rope, wire or cable.
• POM CONSTRUCTION: Adopts high-strength bearing steel material with integral stamping and quenching process. Features excellent hardness, wear resistance and deformation resistance, supports up to 79KG heavy load capacity, durable for long-term industrial and DIY heavy-duty scenarios.
