Choose a heavier series when your application involves higher axial loads or requires a stiffer assembly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan these bearings handle radial (side) loads?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eNo. Thrust ball bearings in the 511xx \/ 512xx \/ 513xx series are designed exclusively for axial (thrust) loads in one direction.

For high-speed or high-temperature environments, consult a bearing lubrication guide for the appropriate viscosity. Relubrication intervals depend on operating speed, load, and temperature — typically every 500–2,000 operating hours for industrial machinery.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do I install a 3-part thrust ball bearing correctly?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eThe shaft washer (with the smaller bore) seats against the rotating shaft, and the housing washer (with the larger bore) seats against the stationary housing or end cap. The ball-and-cage assembly sits between them. Ensure both washers are seated flat and square — misalignment significantly reduces bearing life.
