Perfect fit for my motor project

Ordered the 608 ZZ bearings for a electric motor rebuild. They fit snugly and spin very smoothly. No noise at all under load. Great value for the price.

Smooth rotation for drone motors

Bought the 605 ZZ for custom drone builds. The ABEC-7 precision is noticeable. Spins freely and balances well. Will order again.

Reliable for robotic arms

Using these 604 RS bearings in a small robotic arm. They handle the lateral load well and the rubber seals keep dust out effectively. Highly recommend.

Good quality, slight grease smell

The bearings are well made and precise. There was a slight smell from the grease upon opening, but it dissipated after running them for a few minutes. Overall satisfied.

Standard industrial quality

These meet standard specifications for deep-groove ball bearings. Dimensions were accurate when measured with calipers. Good for general machinery maintenance.

5 FAQ

Q: Are these bearings suitable for high-speed applications?

A: Yes, depending on the precision rating selected. ABEC-5 and ABEC-7 are recommended for higher RPM applications such as drones or spindles.

Q: Is the inner diameter of the 608 bearing exactly 8mm?

A: Yes, the 608 series specifies an 8mm inner diameter, 22mm outer diameter, and 7mm width according to ISO standards.

Q: Can I purchase these in bulk quantities?

A: Yes, we offer bulk pricing for orders over 50 packs. Please contact our sales team through the store messaging system for a quote.

Q: Do these come pre-lubricated or do I need to add oil?

A: All bearings come pre-lubricated with high-grade grease suitable for general use. Additional lubrication is not required immediately.

Q: What is the difference between ZZ and 2RS seals?

A: ZZ denotes metal shields on both sides, offering less friction but less protection. 2RS denotes rubber seals on both sides, providing better protection against dust and moisture.
