Roller skate wheels made from high-elastic polyurethane polymer, hardness 82A, with carbon steel ball bearings Key benefits - Durable, elastic material: High-quality polyurethane polymer provides excellent elasticity and wear resistance so wheels retain shape and performance during regular use. - Smooth, fast and quiet ride: Carbon steel ball bearings deliver stable, low-noise rotation for consistent speed and longer service life. - Effective shock absorption: The high-elastic PU reduces impact transmitted to feet and joints, improving comfort on uneven surfaces. - Versatile surface performance: With an 82A hardness rating, these wheels perform well indoors and outdoors, adapting to asphalt roads, park paths and rink floors. What this solves - Reduces vibration and foot fatigue on rough surfaces so you can skate longer with greater comfort. - Provides reliable, stable speed and low rolling noise for safer, more enjoyable sessions. - Resists wear and deformation so you replace wheels less often. Features at a glance - Material: Polyurethane (PU) polymer — high elasticity and abrasion resistance - Bearings: Carbon steel ball bearings — long life and smooth rotation - Hardness: 82A — suitable for mixed indoor/outdoor use - Function: Designed specifically as roller skate wheels for comfortable, stable skating Practical use scenarios - Indoor rink practice: Smooth, consistent roll and low noise help you focus on technique. - Outdoor street or asphalt skating: 82A hardness and shock absorption reduce vibration from uneven pavement. - Park or boardwalk cruising: Good balance of grip and speed for recreational rides on mixed surfaces. Tone and reliability - Professional-grade materials and construction focused on durability, comfort and predictable performance. - No added claims beyond material, hardness and bearing type — designed to meet practical skating needs.
