Timken 304PP Radial Ball Bearing

This Timken 304PP radial ball bearing carries the industry-standard 6304 designation and arrives new in a double-sealed configuration. It suits hobbyists and collectors who want a genuine Timken component for display or light mechanical projects. The alloy-steel rings and steel cage are factory-lubricated with pillowblock grease and rated ABEC 1 for standard precision.

Simple press-fit installation with metric dimensions

The bore measures 20 mm with a tolerance of +0/-0.010 mm and the outside diameter is 52 mm, so the bearing seats directly into a matching housing without adapters. The 15 mm outer ring width and 1.1 mm fillet radius match the 6304 envelope, reducing the risk of misalignment. Double contact seals keep the grease in and contaminants out, which is the most common cause of premature failure in unsealed units.

Steady load handling within rated capacity

Under sustained radial loads the dynamic capacity of 17,700 N provides a reliable ceiling for continuous operation. The pillowblock grease maintains film strength during extended runs, while the contact seals limit lubricant loss. The ABEC 1 rating means running accuracy is adequate for general rotary motion but not for high-speed precision spindles.
