Heavy-duty roller bearings, such as PBC Linear's Hevi-Rail® combined bearing system, integrate axial and radial load capabilities for robust linear motion in demanding applications. In a telescopic racking case study, Hevi-Rail enables full extension of racking systems, simplifying loading and unloading with a capacity of up to 700 lbs. Its durable, welded steel construction and adjustable or fixed bearing options ensure reliable performance in high-load environments like logistics, construction, or industrial storage, supporting up to 3-meter travel lengths for seamless operation.
