MFR93 9 mm 3 mm 2.5 mm Frequently Asked Questions about MFR93 Metric Miniature Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing MFR93 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Metric Miniature Deep Groove Ball Bearings.
To match diverse operational dynamics, CHG Bearing supplies MFR93 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
Beyond standard alloy steel, CHG Bearing can customize the MFR93 Metric Miniature Deep Groove Ball Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Model MFR93 is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 3 mm) and steep thermal gradients between inner and outer rings.
