A single row deep groove ball bearing from the SKF TNH/HC line comes with a polyamide cage and C3 internal clearance. It is built for running speeds on the higher side where heat build-up needs to stay low, and it takes moderate radial and axial loads in both directions. MR Industrial Accessories LLC supplies this series and can help you match the exact variant to your equipment.
Reading the code is the first step. Take 6305 TNH/HC5C3: the digits at the front give the size and dimension series; TNH points to a glass fiber reinforced polyamide cage made for elevated temperatures; HC5 means the rolling elements are ceramic; and C3 tells you the internal radial clearance is wider than standard. Get those suffixes right and you order the bearing you actually need.
You will find these bearings in food, chemical, pharmaceutical and other process plants, as well as in electric motors, pumps, fans and transmission equipment. They suit lines that run at high speed with moderate temperatures and where maintenance intervals matter. MR Industrial Accessories LLC serves customers across the United States, Canada, Mexico and South America.
Choosing comes down to radial and axial load, speed and operating temperature. The TNH cage handles heat better than a standard polyamide cage, and C3 clearance is the usual pick when fits are interference or when a thermal gradient exists between rings. Fit the bearing with proper tooling, never by direct impact, and lubricate as the manufacturer specifies.
Other makers offer bearings with comparable features, but their part numbers differ. Before swapping brands, check the critical dimensions and the running conditions. The same envelope size can arrive with a different clearance, cage or rolling element material, so interchange is not automatic. If you are unsure, we can help you find the correct replacement.
Have the full part number ready, for example 6305 TNH/HC5C3, and send it by WhatsApp or email. We reply promptly with a quote and can point you to a variant with another clearance or cage if that is what your application calls for. Our team can also suggest equivalents and help you choose.

Frequently asked questions
- SKF 6305 TNH/HC5C3 bearing: what are its dimensions?
- SKF 6305 TNH/HC5C3 measures 25 mm across the bore and 62 mm across the outside diameter; its width is 17 mm (25 x 62 x 17 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6305.
- What does the TNH suffix mean on this bearing?
- TNH identifies a glass fiber reinforced polyamide cage. It is intended for higher temperatures than a conventional polyamide cage, which makes it a frequent choice where heat is a concern.
- When should I use C3 clearance instead of standard?
- C3 is the better fit when the shaft or housing uses interference fits, or when the inner and outer rings see different temperatures. It keeps the operating clearance from closing up and overloading the bearing.
- Can I replace this bearing with one from another brand?
- It can be done, but confirm that the main dimensions, internal clearance, cage type and rolling element material all line up. Equivalent part numbers are not always identical. Send us the original number if you want help checking.
