I recently picked up this flange bearing from a reliable seller in the Industrial and Scientific category and was very impressed with its quality. As my tests showed it operates smoothly and quietly, which is essential for any industrial setting.The zinc aluminum construction is durable and long-lasting, and the design is perfect for my specific power transmission needs. The only downside is that it may not accommodate higher load capacities. Overall, this is a great product that i highly recommend TO others in need of a reliable flange bearing..
