Why Choose 6701ZZ Bearing?

6701ZZ is useful when a design requires a 12mm bore but cannot fit a wider standard bearing. The 4mm width helps reduce space and weight in compact equipment. Its ZZ shielded structure provides low-friction rotation and helps retain grease inside the bearing during operation.

Application Scenarios

Compact motor assemblies
Instrument shafts
Robotic mechanisms
Office automation equipment
Medical and laboratory devices
Small transmission systems
Precision rotating structures

Selection Notes for Buyers

Before ordering 6701ZZ bearings, buyers should confirm shaft size, housing space, working speed, load, clearance, grease, and noise requirements. If the application has high-speed or low-noise requirements, it is important to confirm lubrication and clearance before mass production.

6701ZZ vs 6700ZZ

The main difference is the bore size. 6700ZZ has a 10mm inner diameter, while 6701ZZ has a 12mm inner diameter. If your equipment uses a 12mm shaft, 6701ZZ is the correct choice. If the design uses a 10mm shaft, 6700ZZ may be more suitable.
