For cam tracks, guide rails and motion systems that need a shaft-mounted support roller, the MCGILL MCFRE series cam follower is a metric option with SX lip sealing. It handles radial loads and moderate tilting moments in demanding conditions. The line covers sizes from MCFRE 22A SX through MCFRE 80A SX, making it a common choice in agricultural equipment, conveying systems and industrial automation.

Reading the part number helps you match an existing roller. MCFRE points to MCGILL metric cam followers from the CAMROL family, while SX means the bearing has lip seals. The number that follows — 22, 26, 40, 47, 52, 62, 72 or 80 — sets the roller size and outside diameter, so an MCFRE 40A SX is larger in outside diameter than an MCFRE 22A SX. That difference affects both load capacity and the space needed for mounting. The letter A marks a construction variant within the series.

These cam followers show up in cam and eccentric mechanisms, packaging machinery, chain conveyors, presses, bending machines and linear guiding devices. In agriculture, seeders and harvesters use them as well. When a plain bushing or standard roller no longer provides enough capacity or service life, this style of support roller is often the replacement path.

Selection comes down to three dimensions: shaft diameter, roller outside diameter and width. SX sealing keeps contaminants out and helps retain lubricant, which suits dusty, humid or splash-exposed areas. At mounting, check shaft alignment and avoid impacts that could harm the sealing lips. Many applications run with lifetime lubrication, though severe duty may call for relubrication through a passage. Always confirm load and speed conditions before settling on a size.

Interchange is possible with other brands that follow the same dimensional nomenclature for metric cam followers. Load ratings and materials can differ from one maker to another, so verify the technical data before substituting a component. The MCFRE series with SX sealing is a solid reference when extra protection is needed. If you want guidance, our team can help you identify the right option.
