FAQ

What size shaft can I use with this bearing?

The bearing features a 1/4 inch bore, which accommodates shafts ranging from 0.20 to 0.25 inches in diameter. This size is common in many automotive, industrial, and robotic applications, making the product a versatile choice for a variety of projects.

Are the jam nuts compatible with other thread sizes?

The jam nuts supplied are sized for the 1/4‑28 UNF thread on the bearing. If you require a different thread pitch, additional adapters or custom nuts can be used, but we recommend matching the original specifications to maintain optimal performance.

How does the zinc plating affect corrosion resistance?

Zinc plating creates a protective barrier that significantly reduces the risk of rust and oxidation, especially in humid or chemically aggressive environments. This coating extends the bearing’s service life and minimizes maintenance requirements.

Can I use these bearings in high‑temperature applications?

While the carbon steel housing and chrome steel ball are designed for a broad temperature range, extreme heat above 200 °C (392 °F) may affect material properties. For high‑temperature scenarios, consider specialized bearings rated for those conditions.

What is the warranty period for this product?

Kozelo provides a one‑year limited warranty covering manufacturing defects and material failures. If you encounter any issues within this period, contact our support team for a replacement or repair solution.
