Pegasus Series 1 Linear Bearings feature Silicon Nitride ceramic balls

Pegasus Linear Bearings are available in closed and open series in 1.000 in., 1.250 in., 1.500 in. and 2.000 in. sizes with 220 lb, 352 lb, 490 lb, and 858 lb ratings respectively. Unit’s shell, bearing retainer and end caps are made from Armoloy TDC coated 440 stainless steel. These bearings are used for zero clearance on Class L linear shafting. Armoloy coating reduces the amount of surface area in contact with SiNi balls.

LM76 has developed the most corrosion resistant linear bearing available. In space, deep under the sea, or in the harshest environments when there can be no “Plan B,” Pegasus Series 1 Linear Ball Bearings can be counted on to perform. In some applications linear bearings will not move for days, weeks, months or even years, however, when called on to perform they must work as if they just came out of the box. LM76’s Pegasus Series 1 Linear Bearings feature Silicon Nitride (SiNi) Ceramic Balls in a shell with retainer and end caps all made from 440 Stainless Steel and then ArmorloyTM coated.

Silicon Nitride was selected for the balls because it is: 40% lighter than steel, inert to chemicals (vapors, sea water, caustic washing and sterilizing solutions), capable of higher speeds and higher loads: (RC78 hardness), FDA compliant (used in surgical instruments), and does not corrode or support electrolysis.

The shell, bearing retainer and end caps are made from 440 Stainless Steel and coated with Armoloy TDCTM (Thin Dense Chrome). Armoloy is a hard (78Rc), coating with a micronodular surface texture. The coating’s nodular finish reduces the amount of surface area in contact with the SiNi balls reducing friction and extending life.

Pegasus Linear Bearings are available 2 series (closed and open), and in 4 sizes (1.000″, 1.250″, 1.500″ and 2.000″). Dynamic load rating for these bearings are: 1.000″ 220 lbs, 1.250″ 352 lbs, 1.500″ 490 lbs, and 2.000″ 858 lbs. Bearings are designed for zero clearance on Class L linear shafting. For maximum performance, we recommend LM76 Case Hardened 440 Stainless Steel shafting with Armoloy™ coating.

Founded in 1976, LM76 has been a leading designer/manufacturer of linear bearings, slides and linear motion systems. LM76 is renowned for its industry leading Minuteman Teflon® Composite linear bearings. LM76 is a leading supplier of precision linear shafting: RC60, 300 Series Stainless Steel, and ceramic coated aluminium shafting. LM76 also offers several FDA/USDA compliant linear bearings and slides for the food processing, pharmaceutical, medical, and packaging industries.
