For when a linear bearing simply cannot fail

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 armorloy coated.

Silicon Nitride was selected for the balls because it is 40% lighter than steel, inert to chemicals (vapours, sea water, caustic washing and sterilising 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 micro-nodular 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 in two series (closed and open), and in four sizes (1,000, 1,250, 1,500 and 2,000"). Dynamic load rating for these bearings are: 1,000" 220lbs, 1,250" 352lbs, 1,500" 490lbs, and 2,000" 858lbs. Bearings are designed for zero clearance on Class L linear shafting. For maximum performance the company recommends LM76 Case Hardened 440 stainless steel shafting with armoloy coating.
