1200TNH Bearing Product Overview & Core Advantages
The 1200TNH is a double row angular contact ball bearing designed for applications requiring high rigidity and compact design. This precision bearing excels at handling combined loads, simultaneously supporting significant radial forces and moderate axial loads in both directions. Its bearing dimensions (10mm bore, 30mm OD, 9mm width) make it ideal for space-constrained applications where reliable performance is critical. Manufactured with chrome steel rings and balls, and featuring a nylon cage, it delivers consistent operation across a wide temperature range from -30°C to 110°C.
