Frequently Asked Questions

Q: What is the difference between the ABEC-3 and ABEC-5 6305ZZ bearings?

A: The ABEC-3 6305-2Z is an economical option with standard tolerances and a surface roughness of Ra 0.08, suitable for most general-purpose machinery. The ABEC-5 6305-2Z offers tighter dimensional tolerances and a finer surface roughness of Ra 0.05, making it the preferred choice for applications requiring higher rotational accuracy and smoother operation.

Q: What do the "ZZ" or "2Z" designations mean on the 6305ZZ bearing?

A: The "ZZ" or "2Z" designation indicates that the bearing has dual metal shields on both sides. These shields help keep lubricant in and contaminants such as dust and debris out, reducing maintenance requirements and prolonging bearing life.

Q: Are these bearings compatible with standard 6305 specifications?

A: Yes. The Kande 6305ZZ bearings follow standard 6305 deep groove ball bearing dimensions of 25mm inner diameter × 62mm outer diameter × 17mm width, making them compatible with any application that specifies a 6305 or 6305-2Z bearing.

Q: How many bearings are included in this listing?

A: This listing includes 2 pieces (2pcs/lot) of the 6305ZZ deep groove ball bearing, giving you a spare or allowing you to replace both sides of a shaft simultaneously.
