INA high-precision crossed roller bearings, SX, XSU, and XV series


INA high-precision crossed roller bearings, SX, XSU, and XV series

INA crossed roller bearings are premium solutions for applications requiring compact design, high rigidity, and exceptional accuracy. These INA bearings can support radial loads, axial loads from both directions, tiltigng moments and any combination of loads. This often allows for the replacement of complex arrangements involving multiple bearings with a single, streamlined bearing position.

Product Series

The INA crossed roller bearing range consists of three primary series, each designed for specific mounting and performance requirements:

SX Series

INA SX series crossed roller bearing corresponding to dimension series 18 to DIN 616, not sealed, greased, with clearance, reduced clearance or preloaded, outer ring circumferentially split and held together by three retaining rings.

XSU Series

INA XSU series crossed roller bearing, sealed on both sides, greased, preloaded, centreed on the insde and outside diameter, bearing rings can be screw mounted directly on the adjacent construction.

XV Series

INA XV series crossed roller bearing, sealed on both sides, greased, with clearance, can be preloaded by locknut, inner ring circumferentially split, outer ring can be screw mounted directly on the adjacent construction.

INA crossed roller bearing characteristics

  • High Load Carrying Capacity: Capable of supporting complex combined loads in a single bearing position.
  • Exceptional Rigidity: Offers high tilting moment rigidity, which is essential for precision robotics and machine tools.
  • High Running Accuracy: Engineered for applications where precision rotation is critical.
  • Temperature Resistance: Suitable for operating temperatures ranging from –30 °C to +80 °C.
  • Anti-Corrosion Protection: Available with Corrotect® special plating for enhanced resistance to environmental influences.

Typical Applications

INA crossed roller bearings are widely used across various high-tech industries, including:

  • Robotics and Handling Systems: Where high rigidity and compact size are paramount.
  • Machine Tools: For high-precision rotary tables and gearboxes.
  • Medical Equipment: Providing smooth and accurate movement in scanning and surgical devices.
  • Lifting and Conveying Gear: Such as pedestal bearing arrangements in lorry-mounted cranes.
  • Antennae and Measuring Equipment: Where accuracy and smooth running are essential criteria.

Designation and Ordering Guide

To order the correct INA crossed roller bearing, you need to use the standardized designation system. The designation consists of the bearing type, series, dimension series, size, and specific suffixes.

Designation

Every INA crossed roller bearing has a designation. The designation consists of several parts. It indicates, taking the crossed roller bearing SX as an example: SX 01 1824

  • SX: The type, crossed roller bearing SX
  • 01: The series 01
  • 18: The dimension series 18 to DIN 616
  • 24: The dimension-specific part, size 24 

Suffix

Suffixed are placed after the dimension-specific part. The indicate:

  • The bearing clearance or Preload
    • e.g. VSP for a preloaded bearing
    • e.g.  RL0 for low clearance design
  • The special design
    • e.g. RR for corrosion-resistant design with Corrotect plating.
