Plain Linear Bearing - Round Flange SFPMR50C 50mm Compensated ID

Round flanged plain linear bearing with a 50mm ID, a compensated running clearance, and a standard-size aluminum housing featuring a self-lubricating FrelonGOLD® liner bonded directly to the bore of the housing. The round flange allows secure mounting to a machine frame or plate, while the lined bore supports maintenance-free linear, rotational, and oscillating motion along a round shaft. Unlike recirculating ball bearings, the FrelonGOLD® 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.

  • Compensated 0.0015” per side clearance aids alignment and speed
  • Temperature range -240°C to 204°C (-400°F to +400°F) fits harsh conditions
  • Supports linear and rotational movement for versatile applications
  • Optional liners: Frelon®J for corrosive chemical environments or FDA-approved Frelon®W liners for food-grade applications
  • Maximum Speed: Up to 8 m/s (315 in/s)
