Pilot Sleeve Polyamide wheel centering sleeves recently surpassed competitive products in an independent test of wheel centering devices for commercial trucks, according to the company.
The test was performed to replicate the clamping force generated on hub-piloted commercial vehicle wheel/hub assemblies. The test compared the clamping force generated by the OEM-style flange nuts and various wheel centering devices.
“Not only did our product improve the clamping forces produced by the OEM-style nut alone, but we outperformed all tested competitive products,” said Ben Graham, national sales manager of Ken Tool.
The test was performed by Braun Intertec, an independent testing facility. It compared Ken-Tool’s Pilot Sleeve polyamide wheel centering sleeves to some competitive products.
Specifically, a calibrated 500 feet-pounds force of torque was applied to a 22-millimeter stud embedded with a strain gauge, simulating clamping forces securing a truck wheel to the hub. This was done three times for an OEM-style flanged nut, three times for each competitive product, and three times using Ken Tool’s product. All data was then averaged for consistency.
Ken-Tool’s Pilot Sleeve wheel centering sleeves are manufactured to be used with steel or aluminum commercial truck steer wheels, drive wheels and inside/outside dual wheels that use two-piece flange nuts. Made from a durable, non-corrosive mil-spec grade polyamide, the sleeves are used to correct off-center wheel stud alignment on wheel mounting holes, which if uncorrected, can lead to out-of-tolerance radial wheel runout. The self-sizing sleeves take up the gap between the 22mm wheel studs and the 26mm wheel mount holes regardless of wheel condition.
The Ken-Tool Pilot Sleeve inserts mount into the wheel mounting holes using the Pilot Sleeve installation tool (No. 30630). With the wheel and tire jacked up off the ground, and all flange nuts removed, Pilot Sleeve inserts are ratcheted onto the studs and into the wheel hole. Flange nuts are then reinstalled on the studs to the proper torque. When it becomes time to remove the wheel, the sleeves can be removed using the removal end of the installation tool.
Pilot Sleeve centering inserts are available in a six-piece package and in bulk pails which includes the installation tool.
