💡 What is a needle roller cage used for in linear slide units and bearing assemblies? It secures and spaces rollers so assemblies run smooth and handle high radial loads with a low profile. - Keeps needle rollers aligned for reliable linear slide unit performance and low-friction motion - Distributes radial load across many rollers to increase load capacity in bearing assemblies - Fits sealed ball bearing arrangements and pairs well with ceramic rollers for high-temp or low-wear setups
