Plain Linear Bearing - Square Flanged SFPM12 12mm Precision ID

Square flanged plain linear bearing with a 12mm ID, a precision round shaft running clearance, and a standard-size aluminum housing featuring a self-lubricating Simplicity® FrelonGOLD® liner bonded directly to the bore of the housing. Unlike recirculating ball bearings, the sliding surface has no rolling elements to jam, seize, or contaminate, making it well suited for harsh conditions involving extreme heat, dirt, vibration, shock, or washdown exposure. The precision running clearance provides a closer fit between the shaft and bearing, helping reduce play. The square flange allows secure mounting to a machine frame or plate, while the bore lining supports maintenance-free linear, rotational, and oscillating motion along the shaft.

  • Precision running clearance of 0.0005” per side enhances alignment flexibility
  • ISO metric standard size
  • Extreme temperature range of -240°C to 204°C (-400°F to +400°F)
  • Variant ID sizes available from 3/16” to 3” (inch) and 6mm to 60mm (metric)
  • Optional Frelon®J or FDA-approved Frelon®W liners for corrosive chemical environments or food-grade applications
  • Supports linear, oscillatory and rotational movement
  • Vibration damping
