Polyurethane roller skate wheels with carbon steel ball bearings Key benefits — why you need these wheels - Safer grip and longer service life: High-elasticity polyurethane polymer construction is anti-slip and wear-resistant, so the wheels hold edges better and last longer under regular use. - Smoother, faster ride: Built-in carbon steel ball bearings deliver stable performance, consistent speed, and reduced friction for a predictable skating experience. - Comfortable on varied surfaces: The elastic PU material provides effective shock absorption so rides feel smoother and less jarring on uneven terrain. - Quieter operation: Low-noise design reduces rattling and makes skating more pleasant in indoor and shared spaces. Features and performance - Material: Durable polyurethane polymer — high elasticity, abrasion resistance, and anti-slip properties. - Bearings: Carbon steel ball bearings for long life, reliable performance, and improved speed. - Ride quality: Excellent shock damping from the PU construction for comfort on rough or uneven surfaces. - Noise level: Engineered to run quietly to enhance the riding experience. Compatibility and options - Suitable for roller skates used indoors and outdoors. - Recommended for a variety of surfaces including asphalt roads and park paths. - Available hardness options: 82A, 90A, 92A, 95A to match different skating styles and surface conditions. Practical use scenarios - Commuting on city streets: Choose a higher-durability hardness for predictable performance on asphalt. - Recreation in parks and on mixed paths: The elastic PU and shock absorption make longer rides more comfortable over cracks and uneven pavement. - Indoor rink skating: Low-noise operation and good grip support controlled turns and stable performance on smoother floors. What sets these wheels apart - Combination of elastic PU and carbon steel bearings balances comfort, speed, and durability without sacrificing noise control. - Multiple hardness choices let users tailor wheel behavior to their surface and style needs.
