Opening Paragraph
The 6201 ZZ is a metal shielded deep groove ball bearing with a 12mm bore, 32mm outer diameter, and 10mm width. Part of the 62-series light-duty line, the double metal shields (ZZ) protect the factory grease from dust and debris while allowing the bearing to run at higher speeds than rubber-sealed variants. It is widely used in small electric motors, household appliances, power tools, and fans.

FAQ
What is the difference between 6201 ZZ and 6201-2RS?
- The 6201 ZZ uses double metal shields, which are non-contact and allow slightly higher speeds with less friction. The 6201-2RS uses double rubber lip seals that provide a better contaminant barrier and are more suitable for wet or dusty environments. Both come pre-lubricated; the 2RS seals in the grease more effectively, making it preferable for harsh conditions.
- Is the 6201 ZZ interchangeable with other brands?
- Yes. The 6201 ZZ follows ISO 15 / DIN 625 standards. It is dimensionally identical (12×32×10mm) to SKF 6201-2Z, NSK 6201ZZ, FAG 6201-2Z, KOYO 6201ZZ, and NTN 6201ZZ — fully interchangeable.
- What does ZZ mean on a bearing?
- ZZ (also written 2Z) indicates double metal shields on both sides of the bearing. The shields are pressed steel covers that retain grease and deflect contaminants. Unlike rubber seals (2RS), metal shields do not contact the inner ring, resulting in lower friction and higher permissible speeds.
