If you need to stop your ball bearings from sliding out of place, use this RS PRO two-hole flange bearing unit. It's most often used in commercial settings, such as boat yards, factories and construction sites.
This bearing is built for maximum longevity as it's made of cast iron, which doesn't rust or tarnish. The material is also strong enough to resist high vibrations and large axial loads. The component can handle a moderate level of misalignment, so there's no need to worry if your joints aren't perfectly aligned.
There are two pre-drilled mounting holes on the bearing, so it's quick and easy to install. Flange bearings such as this one are often used in food-processing machinery and heating, ventilation and air-conditioning (HVAC) equipment.
