Ball bearing 6x12x4 mm Ricoh 07413506 for office equipment and printers

Single-row ball bearing with dimensions 6×12×4 mm produced for Ricoh office equipment. This compact radial bearing is intended for use in printers, scanners and other small electromechanical assemblies where low-profile support for rotating shafts and components is required. The part is designed to restore smooth rotation and reduce friction in drives, rollers and motor shafts during maintenance or replacement of worn components.

Advantages

The bearing provides precise radial support in a compact package, helping to maintain stable rotation under light to moderate loads. Its small outer diameter and low width make it suitable for confined spaces typical of office machines. The component is manufactured to tolerances appropriate for electromechanical assemblies, offering consistent performance during routine operation and repair.

Suitable for

• Replacement of worn bearings in printers and multifunction devices
• Maintenance of scanner rollers and small drive shafts
• Repair of office equipment with constrained installation space
• Hobby electronics and small mechanical prototypes that require compact radial bearings

When it may not be suitable

This bearing is intended for light to moderate radial loads typical of office equipment and is not designed for heavy industrial loads, high-speed spindles beyond recommended limits, or applications requiring significant axial load capacity. It is a single-row radial ball bearing and therefore may not provide the required performance where specialized bearings (e.g., angular contact, thrust, or sealed high-speed types) are needed.

Key specifications

• Type: single-row radial ball bearing
• Inner diameter: 6 mm
• Outer diameter: 12 mm
• Width: 4 mm
• Typical application: small electromechanical assemblies, office printers and scanners

How to use

Ensure correct bearing orientation and clean mating surfaces before installation. Press the bearing onto shafts or into housings using appropriate tooling to avoid applying force to the balls or raceways. For assemblies in office equipment, follow the device manufacturer’s service manual for disassembly and reassembly procedures, apply the correct lubricant if required by the application, and test rotation after installation to confirm smooth operation.

What to consider before purchase

• Confirm dimensional compatibility with the shaft and housing (6×12×4 mm).
• Verify load and speed requirements of the target application to ensure suitability.
• Check whether a sealed or shielded variant is needed for contamination protection in your environment.
• Match lubrication needs—some assemblies require pre-lubricated bearings or specific grease types.

Usage recommendations

Use for routine maintenance and parts replacement in Ricoh and similar office machines; install with correct tools, maintain cleanliness during service, and select appropriate lubrication to maximize bearing life.
