BA2B440114 AE Double Row Angular Contact Ball Bearing 15x35x20mm Auto Tensioner Non-Standard Sealed Bearing

1. Product Overview

BA2B440114 AE is non-standard double row angular contact ball bearing, overall dimension 15×35×20mm, specially designed for automobile air conditioner tensioner pulley. Equivalent to back-to-back paired single row bearings, compact width saves assembly space. Double lip rubber sealing structure blocks dust, coolant and mud in engine compartment. Double row ball structure bears combined radial and bidirectional axial loads with high rotation rigidity, stable high-speed operation under alternating impact load. Widely matched for car air conditioner tension wheels, engine auxiliary belt pulleys and small automotive transmission components.
