About 51102 thrust bearings:
2 thrust bearings will significantly reduce the friction from nut tightening, therefore the same torque on nuts will generate far greater downward force.
Each thrust bearing can statically bear a maximum axial load force of 16600N ≈1.69 tons.
Thrust bearings will damage if bearing balls were not sitting in the running grooves! And the ball bearings bracket will immediately deform and causing bearing balls to pop out.
Don’t worry! Thrust bearings will be sold by us for $5 ea or $10 for a set of 2.
Each package comes with 2pc of 5mm thick washers for emergency use in case your thrust bearing fails.
About the cheater bar:
During the prototype, we noticed some gunsmiths would mount our vise onto a big cheater bar. You are welcome to do so but you will have to replace the thrust bearings with washers instead. Thrust bearings will get damaged if bearing balls were not sitting in the running grooves! When a cheater bar is used, the bearing will hardly sit level and causing balls to derail and pop out!
Limited lifetime warranty that does not cover tear and wear
Please note thrust bearings, bolts, and nuts are not covered.
These replaceable parts will be available on our site at a very economical price @ $5 ea, or $10 for 2.
