Mechanical - BEARINGS & LUBRICANTS

Lined linear bearings.

• high load
• self-lubricated

Tolerating up to 1,500 psi, the expanded series of 148 bonded Frelon-lined anodized aluminum bearings carry between 4 and 8x the load of ball-bearings, while lasting on average 4-8 times longer than ball-bearings. The bearings are self-lubricating; however, additional lubrication reduces friction 50%, minimizes wear, reduces heat, allows greater speed and extends wear life. Optional liners are available for nonhardened shafting and for use in food applications. The liner dampens shock loads and vibration with no shaft scoring while providing more contact area than ball-bearings. These bearings operate with consistent friction and load-bearing characteristics throughout a temperature range of -400°F to 500°F. Quality Bearings & Components, Garden City Park, NY.

Dry film lubricant. Applied in multi-layer electro-deposition process to wear surfaces, HI-T-LUBE forms a malleable lubricating surface that maintains a coefficient of friction of 0.03 in temperatures between -360°F and 1000°F and compression loads over 150,000 psi.

Small-bore bearings. With a four-point contact design, the MT series medium duty bearings carry radial, thrust and moment loads simultaneously. They can be an economical replacement for duplexed bearing pairs in kingpost designs. The bearings also incorporate a sealing system that provides maximum lubricant retention with minimal seal wear. They are available in bore sizes from 1.97- to 6.69-in. Kaydon Corporation, Muskegon, MI. Free info--Circle 663

Self-aligning bearings. Combining a non-locating CARB toroidal roller with either a double-row spherical roller or self-aligning ball bearings, the applied load is distributed evenly, reducing vibration, noise and running temperature while increasing bearing life.

Enclosed polymer bearings. Since the inner sleeve functions as the mating surface, this polymer-encased polymer bearing functions independently of the shaft material. The coefficient of friction for the PEP bearing is between 0.12 and 0.2 up to 73 psi. igus inc, East Providence, RI. Free info--Circle 664. http://www.OneRS.net/102df-664

Split roller bearings. Offering an average increase of 30% in radial and 20% in axial load ratings with no dimensional increase, the 01E series split roller bearings with split steel cage eliminate cage jointing clips to simplify assembly.

Miniature bearings. Corrosion and heat-resistant miniature ball-bearings made from SV30 steel alloy can withstand heavier loads and operate more quietly than bearings manufactured from conventional stainless steel. The alloy is suitable for applications using environmental media, such as liquid hydrogen, oxygen or hydraulic fluids, and can operate in reduced lubrication or dry-running conditions.
