51200 Series Heavy-Duty ISO Metric Thrust Ball Bearings (51201 – 51226)

51200 Series Heavy-Duty ISO Metric Thrust Ball Bearings (51201 – 51226)

The 51200 Series represents the international ISO standard for medium-duty, single-direction metric thrust ball bearings. Built with a thicker cross-section and larger steel balls than the lighter 51100 series, this heavy-duty design provides exceptional rigidity, higher radial height, and superior resistance to heavy axial loads in a single direction.

Featuring a 3-piece separable construction: A tight-fit shaft washer, a loose-fit housing washer, and a high-strength ball cage. These bearings eliminate axial displacement and withstand intense thrust pressure without operational binding.
