NTN LLH series deep groove ball bearings are single row units with contact seals on both sides. They handle moderate radial and axial loads while keeping lubricant in and blocking dust, water, and chips. Typical uses include electric motors, pumps, fans, conveyors, and agricultural machinery. MR Industrial Accessories supplies these bearings to customers across the United States and Latin America.
The part number tells you the series and size. The first two digits indicate the series: 60 for light, 62 for medium, and 63 for heavy. The next two digits give the bore diameter. For example, 6008LLH is a 60 series bearing, and 6210LLH is a 62 series bearing. The LLH suffix means contact seals on both sides, which retain grease and keep contaminants out. If you need to verify an equivalent, send the complete number via WhatsApp or email.
These bearings suit rotating equipment in demanding conditions: electric motors, centrifugal pumps, fans, gearboxes, conveyor belts, agricultural machinery, and industrial tools. The LLH series is often chosen where moderate dust or moisture is present and relubrication intervals need to be extended.
Selection depends on radial and axial loads, speed, and the operating environment. The LLH contact seal offers good grease retention but creates slightly more friction than a non-contact seal. During installation, check shaft and housing alignment, use the correct tools to avoid damaging the seals, and apply the recommended lubricant. Clean the seat beforehand to prevent early failures.
When replacing a bearing, cross-brand comparisons are common. The basic part numbers of series 60, 62, and 63 usually share main dimensions, but sealing and internal clearance suffixes can differ. If you provide a part number from another brand or an unidentified part, MR Industrial Accessories will identify a compatible alternative. We work with the exact designation on the bearing or equipment drawing.
