Tritan 6309/C3 radial ball bearing collectible

Radial Ball Bearing 6309 for industrial use

The Tritan 6309/C3 is a metric radial ball bearing designed for machinery that operates in oily or greasy environments. Its open closure allows lubricant to circulate freely through the alloy steel rings and grade AISI 52100 balls. The bearing suits maintenance teams and equipment builders who need a standard 6309 industry number replacement. It is not for buyers who require sealed closures or integrated retaining rings for contamination protection.

Open closure simplifies lubrication access

Installation involves pressing the 45 mm bore onto a shaft with a tolerance of +0/-0.012 mm and seating the 100 mm outside diameter into the housing. The open design lets technicians inspect ball paths and apply grease directly without removing shields. The main risk is introducing debris during fitting because the cage and raceways are exposed. No retaining ring is included, so axial location must be provided by the surrounding assembly.

Alloy steel construction handles sustained radial

Under continuous operation the bearing supports a dynamic radial load capacity of 11,900 lbf through its 25 mm wide outer ring. The steel cage maintains ball separation at steady speeds while the alloy steel rings resist deformation over long duty cycles. The ABEC 1 rating indicates standard precision suitable for general industrial runs rather than high-speed precision spindles. Heat dissipation relies on the surrounding oil or grease bath.
