Ten MF105-2RS flanged miniature ball bearings for 5 mm shaft/idler builds. Each bearing is the MF105-2RS size: 5 mm ID × 10 mm OD × 4 mm wide, with double rubber seals and an outer flange for positive location in printed or machined parts. Why use MF105-2RS instead of a plain 105 bearing? Built-in flange: helps keep the bearing seated against the part face instead of walking sideways under light thrust loads. 2RS rubber seals: seals on both sides help keep dust and plastic debris out of the races. Compact 5 mm format: useful where a 5 mm shaft or pin needs a small, located bearing rather than the larger F695 or F625 sizes. Specifications Part number: MF105-2RS Pack size: 10 bearings Type: flanged miniature deep-groove ball bearing Bore / inner diameter: 5 mm Outer diameter: 10 mm Width: 4 mm Seal type: 2RS, rubber sealed both sides Cross-reference: RF1050LL Intended use Use these for compact idlers, belt paths, and small motion assemblies that call for MF105-2RS. The live Voron V0 Belted Z Kit BOM uses 2 × MF105-2RS bearings. Gotchas This is the flanged MF105-2RS bearing, not a plain MR105-2RS bearing. Check your printed part or BOM before ordering: this is 5 × 10 × 4 mm, smaller than F695-2RS or F625-2RS.
