LINK-BELT 6600 series 4-bolt flange bearings are mounted units that pair an insert bearing with a circular flange housing. They hold a rotating shaft perpendicular to a flat mounting surface and secure it with four anchor points. MR Industrial Accessories LLC supplies this line to industrial customers across the United States, Canada, Mexico and South America.
The part number breaks into three parts. The PLB prefix marks the 4-bolt flange family. The four digits that follow give the size inside the 6600 series. The FR suffix defines the housing and sealing arrangement. Each complete code covers a set of standardized dimensions: shaft diameter, bolt spacing and mounting height. Send the full code, or the shaft and flange measurements, and the team will confirm the right unit.
Typical installations include belt conveyors, bucket elevators, mixers, mills, centrifugal pumps and other process equipment in food, chemical and aggregate plants. A 4-bolt flange mounts to sheet metal or profile structures, with the shaft leaving the mounting face at a right angle. That layout helps with alignment where access is tight.
Selection comes down to three checks: shaft diameter, the center distance between flange bolt holes, and the radial load the bearing has to carry. The FR seal keeps dust and moisture out, which suits areas with airborne particles or frequent washdowns. At installation, clean and flatten the mounting surface, tighten the four bolts in a cross pattern, and confirm the shaft turns freely. Renew lubrication on the duty cycle using the grease specified for the application.
When you replace a bearing, interchangeability between brands hinges on matching flange dimensions and shaft diameter. The LINK-BELT 6600 series has counterparts in other mounted bearing lines, but the code alone is not enough. Compare drawings or measure the flange and housing. MR Industrial Accessories LLC can point you to a compatible alternative once you provide the measurements or the original code.
To request a quote, send the code from your parts list by WhatsApp or email. The team replies promptly and can suggest equivalents or help you choose if you are after a variant that is not listed. If you only have the model or measurements, include those and the team will identify the corresponding option.

Frequently asked questions
- How do I identify the flange bearing I need?
- Measure the shaft diameter, the flange bolt spacing and the housing outside diameter. With those figures, or the complete bearing code, the team can quote the exact model from the series.
- What does the FR suffix mean on these bearings?
- The FR suffix signals a specific housing and sealing configuration within the series. To confirm equivalence with the bearing you are replacing, send the code and the main dimensions.
- Are LINK-BELT bearings interchangeable with other brands?
- They can be, provided the flange dimensions, shaft diameter and mounting height match. Do not rely on the code alone: compare drawings or measurements. The team can indicate a compatible alternative.
