DG407216 Open Non-Standard Auto Gearbox Deep Groove Bearing

DG407216 non-standard single-row open deep groove ball bearing, overall dimension 40mm inner bore × 72mm outer diameter × 16mm width, DG series dedicated transmission bearing matching vehicle automatic gearbox differential and auxiliary shafts. Open structure without rubber seals, equipped with stamped low-carbon steel cage and standard C0 internal clearance. It bears radial load and minor bidirectional axial load, runs stably and low-noise under long-term high-speed shifting vibration inside transmission housing. Produced with fully quenched high-purity GCr15 chrome bearing steel and tight dimensional tolerance control, fully interchangeable with original OEM DG407216. Complete formal quotation will be provided within 24 hours upon inquiry.

• Open design enables full circulation of gearbox oil, excellent heat dissipation, no rubber seal aging, swelling or leakage risks under long-time high-temperature oil immersion
• Superfinished deep groove raceway lowers rolling friction, maintains steady continuous rotation under frequent gear shift impact
• High-hardness uniform GCr15 steel delivers outstanding wear resistance and anti-fatigue performance, extends transmission service life greatly
• OEM unified overall dimension, direct replacement without modifying gearbox housing, shaft and matching accessories
• Lightweight stamped steel cage reduces rotation inertia, suitable for medium-high speed continuous transmission operating conditions
• Standard P0 precision grade, P6/C3 clearance customizable to meet automotive OEM assembly standards
• Stable mass production output, cost-effective for aftermarket repair and bulk wholesale orders

Q1: What is the applicable lubrication method for DG407216?
A1: It is designed for gearbox circulating transmission oil lubrication; high-speed anti-wear gear grease can be filled if used for independent assembly.

Q2: What is the difference between open DG407216 and rubber sealed bearings?
A2: Open bearing has no rubber seals, installed inside gearbox housing relying on circulating gear oil for lubrication and cooling; rubber sealed bearings are used for external exposed dusty shafts with grease lubrication.

Q3: Can DG407216 replace original bearings directly?
A3: Yes, inner bore, outer diameter and width dimensions are fully consistent, no modification to gearbox components required during replacement.
