Hypergrip Bearings
Can anyone give me the bearing sizes for hyperformance hypergrips? I have a set on my Vibe 50 and just want to get some spare bearings for them.

Also, I see that the two radial bearings have a sleeve around them. Usually to remove bearings from metal grips I would heat it up a little but in this case I don't know if the heat would damage the sleeve (Looks like a plastic sleeve...correct me if I'm wrong).

If so..is there a special way to remove the bearings from these grips? I know Hyperformance had some documentation on their web site but its been down for quite a while.

One last thing...anyone know were can I get the sleeve for the radial bearings?

Thanks

The Hypergrips for my Synergy N9 use the stock size bearing with a sleeve that is metal. It looks and feels like black anodized aluminum. I'm not sure if they used the stock bearings for your JR Vibe 50. I would like to belive HyperpermanceRC would. I just replaced the bearnings on mine last weekend. I did not have to use heat....it might have help as they are a tight fit. Install is easier than removal. Be careful with the sleeves has they are extremely thin and can deform with little effort. With you thrust washers in place install the sleeve first then your sealed bearings , if the sleeve is installed on the bearing during install the sleeve tended to press off the bearing. Caused the bearing the seat with the sleeve extruded from the grip by 2mm. Best thing to do is pull one grip off and remove the inboard bearing(should be the easist to remove) and meassure your bearing cross referece your repair manual. All 4 should be the same size.

Hi guys

I thought the thin black sleeve was plastic.

The Vibe 50 and Synergy grips are the same metal, with different carbon pieces. I think..... i am 99% sure.

The Synergy bearing is: 8 x 16 x 5 mm.

Cool! Thanks guys! The bearings are 8x16x5 (The stock vibe grips use 8x14x4)...Grips are exactly the same as the synergy grips except for the carbon arms.

andersons..So basically you just taped the radial bearings out without heat...being careful not to damage the sleeve?

On a side note..it so sucks that Hyperformance is not in business anymore.

yes i use an old feathering shaft , for the inboard bearing insert it in about the width of the bearing , work it side to side to get it unseated and work it till it pops out. the inboard bearing is more difficult take a small flat tip and pry very gently to make a gap between the sealed bearing and the thrust bearing and spaces, then take the small flat tip from the inboard side and gently tap around the race till its about halfway out then give it a good tap make sure you do not hit the spacer or thrust bearing and especially not the sleeve.

to install them i start with inboard side first, line up the bearing square to the seat push in with frim hand pressure , then take an old not to bent feathering shaft , bolt and washer insert shaft so that the washer mates to the bearing using a RUBBER mallet tap the head of the bolt till bearing is bottomed out the bearing and sleeve should be flush to the grip. Repete the same for outboard sidemake sure the thrust bearing and spacer is properly installed before sealed bearing is installed. this time use a punch to hit the bolt head cause the rubber mallet obviously won't fit in the blade grip. if the bearings are not 100% seated when you torque the feathering shaft bolts it will pull them in to the seats. oh and always inspect your head block and mainly the Dampers for weakness tears and elongated hole. $5 part can bring down a $5000 heli.
