Cross-Type Needle-Bearing Universal Joints (Stainless Steel)
Cross-Type Needle-Bearing Stainless Steel Joints are high-precision universal Joints for corrosive or sanitary environments. They maintain minimal backlash over extended periods of time. They are built with roller bearings to reduce friction and deliver superior lifetime at continuous applications and high RPM.
Features:
- Outside Diameter: 0.75"-2.50" [19mm-63mm]
- Operating Speed: up to 6000 RPM
- Operating Angle: up to 45°
- Operating Torque: 28-1,528 Lb-In [3-173 N-m]
- Maximum Torque: 147-5,640 Lb-In [17-637 N-m]
- Needle bearings lubricated for lifetime of joints from 0.75" to 2" OD. (2.50" OD joints can be re-lubricated.)
- Material for Yokes: AISI 303 Stainless [DIN 1.4305], precision machined
- Material for Cross: high-grade alloy steel, hardened and precision ground
- Hub ends available with several standard bore configurations (plain, hex- and square bore, keyway)
- Available as Double Universal Joint or Telescopic Drive Shaft upon request.
