Excellent corrosion resistance

Used these in a humid environment for three months now. No signs of rust or degradation. The ZZ seals keep the grease in nicely.

Perfect for fishing reel repair

These bearings fit perfectly into my saltwater fishing reel. The stainless steel construction gives me peace of mind regarding corrosion. Smooth operation right out of the box.

Good value for money

Quality is solid for the price. One bearing felt slightly stiffer than the others but loosened up after use. Would buy again.

Precise dimensions

I measured each bearing with calipers and they are all within tolerance. Great for precision robotics projects where spacing is critical.

Fast shipping and good product

Arrived earlier than expected. The bearings work well for my skateboard wheels. Slightly louder than ceramic but much more durable.

5 FAQ

Q: Can these withstand exposure to saltwater?

A: Yes, the stainless steel construction and sealed design provide strong resistance against saltwater corrosion, making them ideal for marine applications.

Q: Do I need a special tool to install these miniature bearings?

A: We recommend using a bearing press or a suitable socket that matches the outer ring diameter to ensure even pressure during installation.

Q: What is the main difference between 304 and 440 stainless steel for these bearings?

A: 440 stainless steel is harder and offers better wear resistance, while 304 offers superior corrosion resistance in highly acidic environments. Both are suitable for most general applications.

Q: Are these bearings pre-lubricated?

A: Yes, all bearings come pre-lubricated with low-noise premium grease suitable for high-speed operations.

Q: Is the S608 model suitable for standard skateboard wheels?

A: Yes, the S608 model has the standard 8mm bore size commonly used in skateboard and longboard wheels.
