Design Components Motion control

Available off-the-shelf, cylindrical, self lubricating, sintered bronze bearings from LM76 feature:

  • Precision: 2µm to 12µm for 2mm
  • Load capacity: 100kg/cm2
  • Speed: 30,000rpm
  • Temperature range: -60°C to 230°C
  • Coefficient of friction: 0.02
  • Low noise

Reliable, economic bearings are available in metric sizes (2mm to 100mm ID by 2mm to 120mm long) and have applications in automotive equipment such as alternators.

Lifetime self-lubricating bearings are impregnated in the sintering process with a lubricant to suit the application. Sintered bearings are available in lead-free Bronze, bronze alloys, and Iron.

Flanged bearings (IDs 3mm to 60mm by 4mm to 60mm long) and precision (ID tolerance ISO H7) spherical bearings, with or without a collar, (IDs 4mm to 12mm by 10mm to 23mm ODs) are available, as well as custom sizes and designs.

Alloys include sintered bronze, iron sintered bronze, Paralite (non-migrating lubricant), and Triboloy (chromium, nickel, cobalt alloy for temperatures higher than 1,000°F). Triboloy sintered bearings are resistant to corrosion, erosion, abrasion, and galling, and even at high temperatures they are resistant to oxidation.
