Timken 303PP Collectible Bearing

This Timken 303PP radial ball bearing carries industry number 6303 and arrives new in collectible condition. It suits hobbyists who value original packaging and documented specifications for display or reference.

Double sealed metric bearing for custom assemblies

The bearing has a 17 mm bore diameter and a 47 mm outside diameter with an outer ring width of 14 mm. Alloy steel rings and steel cage construction accept a fillet radius of 1 mm and deliver a dynamic radial load capacity of 15 000 N. The contact seal closure retains SRI 2 lubricant and excludes contaminants without a retaining ring.

Collectible packaging preserves factory condition

The sealed closure and original lubricant remain intact inside the unopened box, protecting the ABEC 1 tolerance of +0/-0.008 mm on the bore. Buyers who need an installed component with a different closure type or a higher precision rating will not find that configuration here.

Questions about this item

What dynamic radial load capacity does the 6303 bearing handle before fatigue?

The 6303 bearing is rated for a dynamic radial load capacity of 15,000 N.

How much heat or noise does the double-sealed 303PP produce during continuous operation?

The double-sealed design retains SRI 2 lubricant and excludes contaminants, keeping noise and temperature rise low during extended running.

What shaft tolerance must I already have for the 17 mm bore to seat correctly?

The bore tolerance is +0/-0.008 mm, so the shaft should be within that range for a proper interference fit.
