INLINE ALUMINIUM SEAL FOR SKAT — 8mm aluminum shaft spacers (15 pcs) Key benefits Protects and stabilizes wheel bearings: precise 8 mm inner diameter and 11 mm length keep bearings aligned for smoother, more reliable rolling. Durable and rust-proof construction: made from aluminum alloy for long service life and resistance to corrosion under regular use. Ready replacement pack: 15 pieces per pack lets you service multiple wheels or keep spares on hand. What it does and why you need it Functions as an inline aluminum seal/spacer to maintain correct bearing spacing and prevent lateral play that causes premature bearing wear. A rigid aluminum alloy body resists deformation better than softer materials, preserving bearing performance over time. Rust-proof finish reduces the risk of corrosion in wet or humid conditions, extending component life. Specifications Material: Aluminum alloy (durable, rust-proof) Inner diameter: 8 mm (for 8 mm shafts) Outer diameter: 11 mm Length: 11 mm Pack quantity: 15 pieces Compatibility and performance Designed for use with 8 mm aluminum shafts. Ideal for inline skates and skateboards where precise bearing spacing and durability matter. Helps maintain stable wheel rotation and consistent bearing alignment during recreational or frequent use. Practical use scenarios Routine maintenance: Replace worn bushings on recreational inline skates to restore smooth wheel spin and reduce noise. Skatepark or street skating: Fit these seals on skateboards used in aggressive riding to keep bearings stable under impact. Team or shop inventory: Keep a 15-piece pack in a repair kit for quick servicing of multiple skates or boards. Maintenance recommendation Replace these seals periodically as roller skate bushings wear out. Regular replacement helps maintain wheel bearing stability and prolongs overall wheel system life.
