Deep groove ball bearings are the workhorse of rotating equipment, carrying moderate radial and axial loads at high speed with minimal upkeep. The NTN EC series with LLH sealing includes the metric sizes most often found in pumps, fans, motors and power transmission assemblies. MR Industrial Accessories LLC supplies these bearings to customers throughout the United States and Latin America.
Reading the EC code is straightforward. The digits after EC give the size: EC-6002LLH, EC-6003LLH and EC-6004LLH are single row bearings with standard outer diameter and width, and a larger number means a bigger bore and higher load capacity. The LLH suffix tells you the bearing is contact sealed on both sides, so grease stays in and dust and moisture stay out.
Typical applications include electric motors, centrifugal pumps, fans, conveyor belts, machine tools and power transmission equipment. Plants in the food, textile and chemical sectors, along with maintenance shops that pull bearings because of wear or noise, are frequent users. When the surrounding area carries dust or moisture, the LLH-sealed EC series is often the practical pick.
Selection comes down to shaft diameter, load type, rotation speed and operating conditions. LLH sealing works well in moderately contaminated settings; for high-temperature or high-speed service, other variants deserve a look. At installation, verify that shaft and housing are aligned and avoid striking the bearing.
Bearings in this series interchange across brands when the standardized dimensions and sealing type line up. If you are holding a part number from another manufacturer, send it over and the MR team will identify the matching NTN equivalent. The same applies when the marking on the old bearing is no longer readable.

Frequently asked questions
- What does the LLH suffix indicate on an NTN bearing?
- LLH means the bearing carries contact seals on both sides. The seal keeps grease in place and blocks contaminants such as dust and water, which suits demanding industrial conditions.
- How can I determine the bearing size I need?
- Measure the shaft diameter at the mounting point; the part number, for instance EC-6004LLH, reflects that size. If you are unsure, send a photo or the shaft measurements and the MR team will help identify the correct bearing.
- Can I request a quote for a specific part number?
- Yes. Send the complete part number and quantity by WhatsApp or email and the MR team will reply promptly with a quote, and can also suggest equivalents if needed.
