Detailed Description

FAG, part of Schaeffler, supplies small bearings engineered for applications that demand accurate dimensions and dependable performance. The 6305-RSR is a 25 x 62 x 17 mm bearing designed for charging system service where correct fit and stable rotation are essential. If you are sourcing a Honda Civic alternator bearing or a 6305-series replacement for electrical repair, this bearing matches the dimensional requirements used in many OE-style assemblies.

This part number 6305-RSR is built for technicians and rebuilders who need a direct-fit bearing specification rather than a generic substitute. Its deep groove design supports smooth operation in alternators and related rotating components.

What It Helps Address

• Alternator bearing noise during engine operation
• Rough or uneven alternator pulley rotation
• Charging system wear caused by bearing fatigue
• Service replacement needs for 6305-series bearing applications
• Dimensional mismatch during alternator rebuilds

Installation Notes and Tips

Verify the bearing dimensions before installation: 25 mm inside diameter, 62 mm outside diameter, and 17 mm width. Press the bearing in and out using proper bearing tools to avoid damage to the races. Confirm the alternator housing and shaft surfaces are clean, and replace worn seals or related components during service when required by the repair procedure.

For Honda Civic alternator repair and other 6305-series charging system applications, confirm the original bearing specification against the removed part before assembly. The FAG 6305-RSR should be installed only where the OE dimensions and bearing type match the application.

Quality Assurance

FAG is an OE manufacturer under Schaeffler, and this bearing is produced to exact OEM standards for precision, reliability, and long service life in charging system use.
