TIMKEN Single row deep groove ball bearing Steel Closure on both sides BB203RR2 A2139A

Single-row deep groove ball bearings are extremely versatile. They are simple in design, suitable for high to very high speeds, very robust in use and thus low-maintenance. Thanks to the deep grooves and the close contact between the grooves and the balls, deep groove ball bearings are extremely well suited to tolerate both radial loads and axial loads in both directions, even at high speeds. Both open (unsealed) and sealed versions of the single-row deep groove ball bearings are available. Bearings sealed on both sides have lifetime lubrication and therefore need not be regreased during use. They have been filled with the exact quantity of high-quality lubricant under controlled conditions.
