Hirobo HI2521110 5 x 7 x 5 Shaft Locating Collar for RC Helicopters  [HI2521110]

Shaft locating collar for linkages

This Hirobo HI2521110 collar measures 5 x 7 x 5 and is designed for use on model helicopter shafts and control linkages. It functions as a locating element to help position parts along the shaft and maintain alignment in the rotor system and tail drive.

Fitting is straightforward: position the collar where required on the shaft and secure it with the model's usual retaining arrangement or a suitable compatible fastener. Since the collar is intended to set position rather than take primary loads, check it sits flush to avoid unwanted axial movement.

For routine maintenance, collars are useful for restoring concentricity after component changes and for defining mechanical travel limits on linkages. Make checking collar seating and clearance part of your standard maintenance checks.
