Slick bearing packer
Hand packing a wheel bearing with grease is time consuming because old grease must first be removed. There is no guarantee of thorough packing. It's also messy and wasteful. An alternative is using a device that fully encloses the bearing, with another device to force grease through the bearing at high pressure. This method requires set-up time, and is limited to the type of grease stored in the pumping device.
To minimize hand contact with grease, and provide a faster and cleaner method, this device uses three components:
A bearing stand to support the bearing
The simple and inexpensive design is patented and could be made of metals or plastics.
