B24-8.NX Open Mini CVT Control Shaft Precision Bearing

1. Product Overview

B24-8.NX non-standard single-row open deep groove ball bearing, dimension 24mm inner × 36mm outer × 8mm ultra-narrow width. Suffix NX = upgraded precision tolerance + anti-deformation structural optimization. Fully interchangeable with NSK B24-8.NX, matched for Asian passenger car CVT tiny hydraulic control valve micro shafts. Open structure without rubber seals, stamped low-carbon steel cage, standard C0 clearance, C3 customizable. Carries light radial load and slight bidirectional axial load, silent stable ultra-high-speed operation under high-temperature CVT oil environment. Made of fully quenched GCr15 steel with micron tight tolerance, direct OEM plug-and-play replacement. Formal quotation within 24h after inquiry.

2. Key Advantages

• Open through design for full CVT oil circulation, efficient heat dissipation, no rubber seal aging or oil leakage
• Smooth superfinished raceway reduces friction, less heat buildup during long continuous high-speed running
• NX optimized precision structure, smaller dimensional tolerance, better anti-deformation performance under frequent micro torque fluctuation
• High-hardness integrated thin-wall inner/outer rings, excellent wear & fatigue resistance, extend CVT service life
• Compact unified OEM mounting size, no modification to gearbox housing or micro shaft during installation
• Ultra-light stamped steel cage minimizes rotation inertia, fits long-term steady ultra-high-speed working of miniature control components
• P0 standard precision, P6 / C3 clearance customizable, stable mass production, cost-effective for aftermarket & bulk OEM orders

3. Applications

Asian passenger car CVT hydraulic control valve micro shafts, compact car gearbox miniature auxiliary shafts, light commercial vehicle tiny precision reducers, small agricultural machinery fine transmission moving parts.

8. FAQ

Q1: What does suffix NX stand for?
A1: N = upgraded precision tolerance; X = reinforced anti-deformation optimized internal structure, better stability under frequent tiny load fluctuation.

Q2: Difference between open B24-8.NX and sealed bearings?
A2: Open bearing installed inside closed gearbox with circulating CVT oil lubrication; sealed bearings for external dusty shafts with independent grease lubrication.

Q3: Can it replace original NSK bearing directly?
A3: Yes, full consistent dimensions, no modification required during assembly.
