The 25*47*12 mm specification fits common motorcycle engine and wheel hub assemblies, making them a versatile solution for maintenance and production.

Technical Details That Maximize Reliability

Precision matters in motorcycle bearings. Our NSK bearings offer P0-P4 precision ratings, with P4 grade options for applications requiring minimal radial runout and high speed stability. The Z2V2-Z3V3 vibration classes reduce noise and extend service life by minimizing internal friction. Available with open, Zz (metal shielded), or 2RS (rubber sealed) designs, these bearings balance protection and heat dissipation—critical for engines that reach high operating temperatures. Grease or oil lubrication options let you tailor performance to specific motorcycle models and usage patterns.

The Hidden Cost of Counterfeit Motorcycle Bearings

Counterfeit bearings may save money upfront, but they often fail prematurely due to poor materials and manufacturing. A single bearing failure can cause engine damage, leading to repair costs 10–20 times the price of a genuine part. worse, unexpected downtime disrupts service schedules and erodes customer trust. Our authentic NSK bearings meet strict Japanese quality standards, backed by ISO9001 certification, ensuring consistent performance and reducing total cost of ownership over time.
