B40-222 Open Non-Standard Auto CVT Heavy Load Deep Groove Bearing

1. Product Overview

B40-222 non-standard single-row open deep groove ball bearing, dimension 40mm inner bore × 82mm outer diameter × 22mm extra-wide width, thick-wall heavy-duty design specially for large torque CVT pulley system. Open design without rubber seals, matched stamped low-carbon steel cage and C0 standard internal clearance. It bears heavy radial load and moderate bidirectional axial load, runs smoothly and low-noise under long-time high-torque variable rotation and high-temperature transmission oil inside CVT housing. Produced with fully quenched high-purity GCr15 chrome bearing steel and strict dimensional tolerance control, fully interchangeable with original OEM B40-222. Complete formal quotation will be provided within 24 hours upon inquiry.

2. Key Advantages

• Open construction allows full flow of CVT fluid for efficient heat dissipation, avoids rubber seal aging, swelling and oil leakage under long-term high-temperature immersion
• Super-finished deep groove raceway minimizes rolling friction, stable continuous rotation under frequent heavy torque impact from pulley operation
• Extra-wide thick-wall inner and outer rings with high-hardness GCr15 material, outstanding wear resistance and fatigue resistance, greatly extend CVT service life
• OEM unified installation dimensions, direct replacement without altering pulley housing, shaft and matching accessories
• Optimized stamped steel cage reduces rotation inertia, adapts to long-term continuous high-load high-speed CVT operation
• Standard P0 precision grade, P6 / C3 clearance customizable to meet auto OEM assembly standards
• Stable mass production, cost-effective for auto repair aftermarket and bulk OEM supporting orders

3. Applications

Heavy-duty passenger car CVT driven pulley assemblies, automatic transmission differential heavy-load shafts, light commercial vehicle reducers, large agricultural machinery transmission core components.

8. FAQ

Q1: What is the difference between open B40-222 and sealed bearings?
A1: Open bearing has no rubber seals, installed inside CVT housing relying on circulating transmission oil for lubrication and cooling; sealed bearings are used for external exposed dusty shafts with grease lubrication.

Q2: Can B40-222 replace original OEM bearings directly?
A2: Yes, inner bore, outer diameter and width are fully consistent, no modification to CVT pulley components needed during replacement.

Q3: Suitable lubrication mode?
A3: Designed for CVT circulating transmission oil lubrication; high-speed anti-wear gear grease can be filled for independent separate assembly.
