For equipment that sees elevated temperatures and needs dependable radial and axial support in both directions, the SKF deep groove ball bearing in the TN9W/C4H series is a practical choice. Its polyamide cage and special internal clearance address thermal expansion and preload concerns. MR Industrial Accessories supplies this bearing as part of its SKF line, serving maintenance and purchasing teams throughout the United States and Latin America.
Break down the TN9W/C4H code to understand what you are specifying. TN9 identifies a fiberglass-reinforced polyamide cage, which handles high speeds and moderate temperatures. The W indicates suitability for elevated operating temperatures. C4H combines an internal clearance larger than standard with a heat treatment that keeps dimensions stable. A common example is the 6209 TN9W/C4H, a medium-section bearing that carries all these traits.
These bearings appear in electric motors, centrifugal pumps, fans, compressors, and transmission equipment. Food, chemical, petrochemical, and metallurgical operations often rely on them because they manage high speeds and combined loads. Machine tools and continuous-process lines also use them where reliability matters.
Selecting a TN9W/C4H bearing starts with the internal clearance your application needs. A larger clearance like C4H helps offset thermal expansion and prevents excessive preload. Mounting should use suitable tools and achieve precise shaft-to-housing alignment. Follow the manufacturer's lubrication recommendation, and choose sealing based on the working environment. Our team can help you match the bearing to your equipment.
For equivalences, other brands may offer similar designations, but confirm that tolerances, internal clearance, and cage type align with your requirements. Suffixes are not universal, so validate technical specifications before replacing a bearing. Dimensional interchangeability often holds, yet performance can differ with material and heat treatment.

Frequently asked questions
- SKF 6209 TN9W/C4H bearing: what are its dimensions?
- SKF 6209 TN9W/C4H measures 45 mm across the bore and 85 mm across the outside diameter; its width is 19 mm (45 x 85 x 19 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6209.
- What does the C4H suffix mean in an SKF bearing?
- C4H indicates a radial internal clearance greater than standard, plus a special heat treatment for dimensional stability at elevated temperatures. This helps in applications where thermal expansion can affect bearing operation.
- Is this bearing suitable for high temperatures?
- Yes, the TN9W/C4H designation includes features that allow operation at higher temperatures than a conventional bearing. The polyamide cage and heat treatment support reliable performance under demanding thermal conditions, within the manufacturer's limits.
- Can I replace a TN9W/C4H bearing with another brand?
- Often you can, but verify that the other brand offers a bearing with C4H internal clearance, polyamide cage, and equivalent heat treatment. Dimensions are usually interchangeable, but performance may vary. Consult us with the part number and we will advise you.
