💡 What is a caged roller bearing used for in heavy machinery and linear slide units? Caged roller bearings are designed to carry high radial loads while keeping rollers evenly spaced and aligned for smooth operation. This short intro covers common uses and benefits: - Ideal for heavy radial load support in gearboxes, shafts, and conveyor systems - Common choice for linear slide units needing rigid guidance and load capacity - Often selected over sealed ball bearing options when oil holes or relubrication access is required
