KBC 6208-2RS 40mm 80mm x 18mm collectible

KBC 6208-2RS Deep Groove Ball Bearing

The KBC 6208-2RS is a single row deep groove ball bearing built to electric motor quality standards. It suits maintenance technicians, hobby engineers and anyone replacing a worn unit in precision rotating equipment. The C3 internal clearance accommodates thermal expansion in high-speed shafts. Transparent seals let you inspect lubricant condition without disassembly.

Sealed Design Limits Contamination And Noise

Two contact seals keep dust and moisture out while retaining factory grease, reducing bearing noise in normal operation. The C3 fit minimises internal friction once the assembly reaches working temperature, helping to lower power draw across the drivetrain. Standard 40 mm bore, 80 mm outside diameter and 18 mm width match common motor housings without modification.

Direct Replacement For 6208 Series Bearings

This unit replaces any 6208 series bearing where a C3 clearance and contact seals are specified, making the swap worthwhile when the original has developed play or seal wear. It is not for applications that require shielded variants, ceramic rolling elements or a different internal clearance class. Buyers needing a larger bore or higher load rating must select a different series.
