Closed-shell plain linear bearings from the Simplicity® line feature a self-lubricating FrelonGOLD® liner for maintenance-free operation in harsh environments, handling extreme temperatures from -400°F to +400°F (-240°C to 204°C) and resisting dirt, shock, and vibration. Available in inch (3/16" to 4"), ISO metric (5 mm to 80 mm), and JIS sizes, they are designed for end-supported shafting, with static load capacities up to 166,000 lb (740 kN) and speeds up to 8 m/s (315 in/s). Options include aluminum or stainless steel shells, precision or compensated running clearances (0.0005" or 0.0015" per side), and standard or self-aligning ODs to accommodate misalignment. Interchangeable with many linear ball bearings and some bronze bushings, they are well suited for heavy-load applications involving linear, rotational, or oscillating motion.
They offer oil-free operation, vibration damping for smooth and quiet motion, and seal options (nitrile, urethane, viton for ½” ID or 20mm and up). Optional external lubrication and various mounting options, such as O-ring and retaining ring grooves, enhance their versatility.
