3M 7000118709 Ball Bearing Upper Shaft Balancer

Product Description

The 3M 7000118709 is a 6000ZZ double-shielded ball bearing designed to serve as the upper rear shaft balancer on random orbital sanders and orbital sanders. This bearing supports proper shaft alignment and precision balance during tool operation, making it a critical wear component in any sander serviced regularly in production, finishing, or fabrication environments. The double-shield design helps protect the bearing from dust and debris common in sanding applications. Replacement is typically performed by tool repair technicians and shop maintenance personnel as part of scheduled preventive maintenance or when vibration and noise indicate bearing wear.

This bearing is intended for use in 3M random orbital sanders and orbital sanders as the upper or rear shaft position bearing. It is a direct OEM-specification replacement that restores factory balance and alignment characteristics. Shops running high-volume finishing lines benefit from keeping this part on hand to minimize downtime during tool service intervals.

Key Features

• Double-shield (ZZ) design reduces contamination ingress from sanding dust and debris
• Supports proper shaft alignment for precision orbital balance
• OEM-specification fitment for upper rear shaft position
• Sold individually, allowing single-bearing replacement without unnecessary parts
• Compatible with both random orbital and standard orbital sander platforms

Compatibility

Designed as an OEM-style replacement upper shaft balancer bearing for 3M random orbital sanders and orbital sanders.

Installation Notes

Tool repair technicians should power down and disconnect the sander from the air supply or electrical source before disassembly. The bearing should be pressed or seated using appropriate bearing installation tools to avoid damage to the shield or race. Inspect the shaft and housing bore for wear before installing the replacement bearing. Follow the tool manufacturer's service documentation for disassembly sequence and reassembly torque guidance.
