Machined Integrations IS the innovator of the "Patent Pending" o-ringed greaser:
- dedicated to excellent customer service 
- has thoroughly designed and tested products by avid off-road users
- laser marked for ease of identification 
- removable zerk fittings for easy of cleaning. We do not use cheap pressed in zerks - they leave metal shavings inside the tool, waiting to ruin your bearings
- properly sized orings - thick and not stretch out to LAST.
- Patent pending - we are vested in the products for the long haul 

Do not settle for cheaper made products that only have 1 tiny grease port hole! Our tool uses multiple ports to EVENLY distribute grease throughout your bearing. With our tool, you do not have to waste time packing and turning the bearing like the single port tools.

No need to remove your axle to use this 44mm (front) & 40mm (rear) tool set. UTV and ATV bearings constantly fail due to water, dirt, sand, and lack of grease. This tool will replenish the grease your bearings need, as well as push out contaminants. Simply insert tool into your bearing and pump grease through Zerk fitting with your grease gun. Machined from 6061 Aluminum. Fits all Polaris UTV and ATV wheel bearings with a 44mm and 40mm inside diameter. Works with all aftermarket and OEM bearings. Made in the USA. Bearing in pictures is not included, for demo purposes only.
