B32-33 Open Extra Wide Non-Standard CVT Heavy Load Deep Groove Bearing

B32-33 non-standard single-row open deep groove ball bearing, dimension 32mm inner bore × 65mm outer diameter × 33mm ultra-wide width, thick-wall heavy-load design specially for large torque CVT driven pulley system, fully interchangeable with original NSK B32-33. Open design without rubber seals, equipped with stamped low-carbon steel cage and factory standard C0 internal clearance, C3 clearance customizable on demand. It bears heavy radial load and moderate bidirectional axial load, runs stable and low-noise under long-term high-torque variable rotation and high-temperature CVT oil environment inside transmission housing. Manufactured with fully quenched high-purity GCr15 chrome bearing steel and strict micron-level dimensional tolerance control, fully compatible with OEM B32-33 assembly requirements. Complete formal quotation will be provided within 24 hours upon inquiry.

• Open through structure allows full circulation of CVT transmission oil for continuous efficient heat dissipation, completely avoids rubber seal aging, swelling and oil leakage defects under long-term high-temperature oil immersion
• Superfinished ultra-smooth deep groove raceway minimizes rolling friction coefficient, maintains steady continuous rotation under frequent heavy torque impact from pulley variable speed operation
• Extra-wide thick-wall integrated inner and outer rings with high-hardness GCr15 material deliver outstanding wear resistance and anti-fatigue performance, greatly extend the overall service cycle of CVT transmission
• OEM unified overall installation dimensions, direct plug-and-play replacement without modifying pulley housing, driven shaft and matching installation accessories
• Optimized lightweight stamped steel cage lowers rotation inertia, perfectly adapts to long-term continuous heavy-load high-speed working conditions of CVT variable transmission
• Standard P0 precision grade, P6 / C3 clearance customizable to meet mainstream auto OEM assembly matching standards
• Stable mass production capacity with sufficient stock supply, high cost performance for auto repair aftermarket and bulk OEM supporting orders

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

Q1: What is the difference between open B32-33 and rubber sealed bearings?
A1: Open bearing has no rubber sealing lips, installed inside closed CVT housing relying on circulating transmission oil for lubrication and cooling; rubber sealed bearings are used for external exposed dusty shafts with independent grease lubrication.

Q2: Can B32-33 replace original NSK OEM bearings directly?
A2: Yes, inner bore, outer diameter and ultra-wide width dimensions are fully consistent, no modification to CVT pulley components required during replacement.

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