Structure Type:
Inner Ring: It adopts an integral structure with an integrally precision - ground raceway, ensuring the consistency of the roller movement track.
Outer Ring: The split - type design facilitates installation and pre - tightening adjustment, reducing assembly cumulative errors.
Roller Arrangement: Cylindrical rollers are arranged orthogonally at 90° (in an "X" shape).
Materials:
Bearing Rings and Rollers: GCr15 high - carbon chromium steel (surface hardness HRC 60 - 62) or SUS440C stainless steel (corrosion - resistant).
Cage: Nylon 66 (light - weight), brass (high - strength) or customized composite materials.
Size Range:
Metric Series:
Inner diameter: 130 - 360 mm
Outer diameter: 205 - 435 mm
Assembly height: 25.4 mm
Accuracy Class:
Rotational Accuracy: P5,P4.
Sealing Options:
Open Type: Requires regular external lubrication and is suitable for clean environments.
Contact Rubber Seal (UU/U): Dust - proof and splash - proof, suitable for industrial dusty or humid environments.
It can bear radial, axial, and moment loads simultaneously, eliminating the need for additional bearing combinations.
It is suitable for scenarios with limited space
With P4 - level accuracy, it can meet the positioning requirements at the nanometer level.
The nylon cage and thin - walled structure reduce the overall weight of the equipment
