B29-11 Open Non-Standard JF011E CVT Auxiliary Shaft Deep Groove Bearing

B29-11 non-standard single-row narrow open deep groove ball bearing, overall dimension 29mm inner bore × 52mm outer diameter × 11mm narrow width, fully interchangeable with original NSK B29-11 and equivalent HTFB29-11, specially matched for Nissan JF011E, RE0F10A CVT tiny control valve and small auxiliary transmission shafts. Open design without rubber sealing lips, equipped with lightweight stamped low-carbon steel cage and factory standard C0 internal clearance, C3 clearance customizable on demand. It bears light to medium radial load and slight bidirectional axial load, runs ultra-quiet and stable under long-term continuous high-speed rotation and high-temperature CVT fluid environment inside sealed gearbox housing. Manufactured with fully quenched high-purity GCr15 chrome bearing steel and strict micron-level dimensional tolerance control, fully compatible with OEM B29-11 assembly standards. Complete formal quotation will be provided within 24 hours upon inquiry.

• Open through-hole 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-time high-temperature oil immersion
• Superfinished ultra-smooth deep groove raceway greatly reduces rolling friction coefficient, less heat accumulation during ultra-high-speed operation, maintains steady rotation under frequent tiny torque fluctuation of miniature control shafts
• High-hardness integrated thin-wall GCr15 inner and outer rings deliver reliable wear resistance and anti-fatigue performance, effectively extend overall service life of JF011E CVT transmission system
• Compact unified OEM installation dimensions, direct plug-and-play replacement without modifying gearbox housing, miniature auxiliary shaft and matched small installation accessories
• Ultra-light stamped steel cage minimizes rotation inertia, perfectly adapts to long-term stable ultra-high-speed working conditions of CVT miniature control components
• Standard P0 precision grade, P6 accuracy and C3 internal clearance can be customized to meet mainstream Japanese auto OEM assembly matching requirements
• Stable mass production with sufficient stock supply, high cost performance for auto repair aftermarket and bulk OEM supporting orders

Q1: What is the difference between open B29-11 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 B29-11 replace original NSK OEM bearings directly?
A2: Yes, inner bore, outer diameter and narrow width dimensions are fully consistent, no modification to JF011E CVT miniature shaft 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.
