JIS Plain Linear Bearing FJA150 150mm Self-Aligning Crown

Plain linear bearing, self-aligning, closed, with a 150mm JIS precision ID that provides a 0.0005" running clearance per side for a tighter fit and less play on round shafts. Sized to Japanese Industrial Standards (JIS), it is encased in a crowned outer diameter, cylindrical, green-anodized aluminum shell. The crown creates a curved contact surface that lets a compatible self-aligning housing seat the bearing at a slight angle, helping compensate for minor angular misalignment between parallel shafts without forcing the shaft and liner into a rigid bind. It features a bonded Simplicity® self-lubricating FrelonGOLD® bore liner for maintenance-free linear, rotational, and oscillating motion in harsh environments where ball bearings often fail, such as extreme temperatures, dirt, welding splatter, vibration, shock loads, contamination, or washdowns.
