Plain Linear Bearing - FLA48 3.00″ Self-Aligning Crowned OD

Closed self-aligning plain linear bearing with a 3" precision ID which has a 0.0005" running clearance per side. The crowned anodized aluminum shell has a slightly curved outside diameter that lets the bearing seat at a corrective angle inside a compatible pillow block, mounted housing, or machined bore. This self-aligning action helps compensate for minor angular misalignment between parallel shafts, reducing the risk of binding when the shaft and housing are not perfectly aligned. A bonded, self-lubricating FrelonGOLD® liner supports maintenance-free linear, rotational, and oscillating motion without grease in harsh environments where extreme temperatures, dirt, vibration, shock loads, contamination, or washdowns can make rolling element bearings harder to maintain.

  • Inch series - closed anodized aluminum shell
  • Crowned outer diameter for self-alignment (straight ODs have FL part numbers)
  • Precision running clearance: 0.0005" per side
  • Self-Lubricating Bearing Liner: FrelonGOLD® is standard. Operates well in harsh and/or high temperature environments
  • Optional liners: corrosive chemical resistant Frelon®J & FDA Compliant Frelon®W
  • Temperature Rating: -400°F/+400°F or -240°C/204°C
  • Vibration Damping: Ensures smooth and quiet operation
  • Optional double seals available in Polymod, urethane, or high-temperature Viton
  • Optional JKM lubrication system (zirk fitting thru hole, felt wick
