MATERIAL: Roller Cup - Case-Hardened Steel Needle Bearing - 52100 Hardened Chrome Steel Springs - Stainless Steel Cage - Nylon 66 (or Equivalent)

OPERATING TEMPERATURE: Grease +50°F to +160°F

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. Minimum backlash.

SHAFT REQUIREMENTS:Shaft surface hardness must be Rc 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 outerrace. Positive wedging forces preventslipping. Springs position rollers for instantaneous lockup.
