How it works
• Case Hardened Steel Roller Cup
• 52100 Hardened Chrome Steel Needle Bearing
Features:
• Ideal for indexing, backstopping or overrunning operations
• Free rolling one way, drives in opposite direction
• Lightweight, low profile
• High indexing frequency, up to 4 CPS
• Temperature range, grease +10°C to +70°C (+50°F to +160°F)
• Minimum backlash
*Shaft surface hardness must be HRC 58 min.
What It Does
Transmits torque load in one direction. Overruns freely in opposite direction. Either shaft or housing can be driving member.
How It Works
Rollers wedge between shaft and outer race. Positive wedging forces prevent slipping. Springs position rollers for instantaneous lock-up.
