The R series of miniature bearings are available in a wide range of sizes, from 1/16 inch to 1/4 inch (1.588mm to 6.35mm) bore diameter. The outer diameter of these bearings range from 3/16 inch to 5/8 inch (4.762mm to 15.875mm), making them a great option for applications where space is limited.
These miniature bearings are designed to operate at high speeds, with a maximum recommended speed of up to 100,000 RPM. They are also able to carry moderate radial loads and thrust loads in either direction.
R series miniature bearings are constructed with high-quality materials, including stainless steel and chrome steel, ensuring long-lasting durability and reliable operation. They are also available with a variety of sealing options, including open, ZZ (metal shields), and 2RS (rubber seals).
Overall, R series miniature bearings are an excellent choice for applications that require high precision, durability, and reliable operation in a compact space. We offer a wide selection of R series miniature bearings, so you can find the perfect bearing for your specific needs.
