💡 What is a cartridge bearing used for in conveyor and linear slide unit applications?

It’s especially handy when you need a sealed ball bearing that can be serviced in place. Quick overview: - Provides shaft support and alignment for conveyors, fans, and linear slide units to reduce downtime - Preassembled sealed ball bearing cartridge protects against dust and moisture for longer service life - Set-screw locking plus a 1/8-27 NPT relubrication port makes on-site greasing and repairs straightforward
