B24Z-2.N Open Mini CVT Micro Shaft Superfinish Bearing

B24Z-2.N non-standard single-row open deep groove ball bearing, dimension 24mm inner × 38mm outer × 8mm narrow width. Suffix Z = ultra-smooth superfinished raceway; suffix N = precision tolerance upgrade. Fully interchangeable with NSK B24Z-2.N, matched for Japanese CVT tiny control valve micro shafts. Open structure without rubber seals, stamped steel cage, standard C0 clearance, C3 customizable. Supports light radial load + slight bidirectional axial load, quiet stable high-speed rotation under high-temp CVT oil environment. Made of quenched GCr15 steel with tight micron tolerance, direct OEM replacement. Formal quotation within 24h after inquiry.

• Open design for full CVT oil circulation, efficient heat dissipation, no seal aging & oil leakage
• Z superfinished raceway cuts friction, less heat accumulation under long ultra-high-speed operation
• Upgraded N precision tolerance, smaller dimensional deviation, smoother shaft matching
• High-hardness GCr15 rings, excellent wear & anti-fatigue performance, extend gearbox service life
• Compact OEM unified size, plug-and-play without housing/shaft modification
• Light stamped cage reduces rotation inertia, fit continuous micro-shaft high-speed working
• P0 standard precision, P6 / C3 clearance customizable, stable mass production, cost-effective for aftermarket & bulk OEM

Q1: Meaning of suffix Z and N?
A1: Z = super ultra-smooth raceway for low friction high speed; N = upgraded precision tolerance grade.

Q2: Difference between open B24Z-2.N and sealed bearings?
A2: Open bearing installed inside gearbox with circulating CVT oil; sealed bearings for external dusty shafts with grease lubrication.

Q3: Can replace original NSK bearing directly?
A3: Yes, fully consistent dimensions, no modification required.
