Oldboy Sports Ceramic skateboard bearings 608RS ZrO2 8 x 22 x 7 mm set of 8, sealed with super lube

Oldboy Ceramic Skateboard Bearings are an 8-piece set of 608RS ZrO2 ceramic ball bearings (8 x 22 x 7 mm) made for skateboards, longboards, inline skates and rollerblades to deliver faster, smoother, longer-lasting performance.

These bearings swap standard steel balls for zirconia (ZrO2) ceramic spheres and include a nylon cage, rubber seals, super lube and an Oldboy sticker. The combination reduces friction and heat, resists corrosion, and requires less frequent maintenance than typical steel bearings. Designed in the 608RS size, they fit most skateboard and skate setups that accept standard bearings and are built to perform in street, park and cruising environments.

How do these ceramic bearings improve speed and smoothness?

Ceramic balls have a harder, smoother surface than steel, which lowers rolling resistance and keeps rotation steadier at high RPMs. The nylon cage keeps ball spacing consistent for quieter, more reliable spins, while the rubber seals help keep dirt and moisture out.

• ZrO2 ceramic balls reduce friction for faster roll
• Nylon cage maintains consistent ball alignment and less vibration
• Sealed 608RS design keeps contaminants away for smoother operation
• Includes super lube for optimized initial break-in and ongoing performance

Are these bearings durable and low-maintenance?

Ceramic bearings resist rust and wear better than standard steel bearings, which helps extend service life under normal use. While ceramic components are highly wear-resistant, proper installation, periodic cleaning of seals and occasional re-lubrication with the included super lube will maximize longevity.

• Zirconia construction resists corrosion and heat-related degradation
• Sealed shields reduce exposure to dust, water and grime
• Less frequent maintenance required compared with unsealed steel bearings
• Replacement or refund support from Oldboy if not satisfied

Will these fit my skateboard, longboard, or rollerblades?

Yes — these are standard 608RS bearings sized 8 x 22 x 7 mm, which match most skateboard, longboard, inline skate and rollerblade hubs that accept standard bearings. Confirm your wheels use 608-style bearings before purchasing to ensure compatibility.

• Standard 608RS dimensions: 8 x 22 x 7 mm
• Compatible with most skateboard and longboard wheels and trucks
• Also fits inline skates and rollerblades using standard bearing hubs
• Set contains 8 bearings, ideal for four-wheel setups or partial upgrades

What comes in the package and how do I get peak performance?

The package includes eight Oldboy 608RS ZrO2 ceramic bearings, a tube of super lube, and an Oldboy sticker. For best results, install bearings correctly, break them in with moderate rides, and use the supplied lubricant when bearings feel dry or after cleaning.

• Set of 8 ceramic 608RS bearings (8 x 22 x 7 mm)
• Super lube for initial and periodic lubrication
• Protective seals already installed to limit contamination
• Oldboy customer support and replacement/refund policy

Who is this for? These Oldboy ceramic bearings are suited to skaters who want a measurable upgrade over stock steel bearings: commuters, longboard cruisers, park riders and inline skaters seeking reduced friction, quieter roll and greater corrosion resistance. They are especially useful for riders who value speed and low maintenance without changing wheel hubs or hardware. If you need bearings sized other than 608RS, or you ride in exceptionally wet or contaminated environments, consider additional protective measures and routine service to maintain performance.
