KA020XP0 2 x 2.5 x 0.25 inches Robot Ultra-Slim Thin Section Four-Point Contact Bearing

KA020XP0 Four-Point Contact Thin Section Bearing – Ultimate Load-Carrying Performance in an Ultra-Slim Package

The KA020XP0 ultra-thin four-point contact bearing offers outstanding load-bearing versatility on a ultra-thin 1/4-inch cross-section.This constant-section geometry—where the cross-section remains identical regardless of bore diameter—makes the KA series ideal for applications that require large bores but cannot accommodate bulky bearing envelopes.
The KA020XP0’s inner and outer raceways are precision-ground with a gothic arch profile, creating four distinct contact points between each ball and the raceways. This ingenious internal geometry enables a single bearing to carry radial loads, axial (thrust) loads in either direction, and tilting moment loads simultaneously—individually or in any combination.For design engineers, the practical implication is profound: one KA020XP0 can often replace two conventional bearings, simplifying mechanical assemblies, reducing part count, lowering overall system weight.

主要特点:

• All-Directional Load Support in One Compact Bearing
  The KA020XP0 independently handles radial, axial and moment loads, dramatically simplifying design and reducing assembly complexity.

• Space and Weight Savings Without Sacrificing Strength
  The KA020XP0 fits into impossibly tight spaces where standard bearings would be completely impractical. 而且, the design drastically reduces material usage, culminating in a weight of only 0.1 lbs (45 g)—a critical advantage for aerospace systems, lightweight robotics and portable medical devices where every gram must be justified.

• Simpler Design, Lower Cost
  Because the KA020XP0 supports both radial and axial loads, it frequently eliminates the need for two bearing arrangements.A single KA020XP0 fulfills both roles while reducing component count, machining operations, assembly time and overall system cost.
• Long Service Life
  Rings and balls are manufactured from chrome steel, through-hardened to optimal hardness for rolling contact fatigue resistance. This material withstands repeated stress cycles, shock loads and vibration without premature surface fatigue, delivering reliable service even in demanding, high?duty-cycle applications.
• Wide Operating Temperature Range
  With an operating temperature range spanning -65°F (-54℃) to +250°F (121℃), the KA020XP0 performs reliably across extreme thermal environments—from cryogenic aerospace applications to high?temperature industrial processes.
