Notes

1.

Teflon liner permanently bonded to race I.D.

2.

Oscillation load shall be kept within the static load range,

as Teflon liner load endurance is greater than body breaking load.

3.

Made to order only. (from RBT15 to RBT30)

4.

No Load Rotational Breakaway Torque.
Standard All Size: 0.02 ～ 0.34N・m
Low Torque All Size: 0.02N・m MAX
