MF105-2RS Bearings

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.

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.
