The Yale YHP range provides professional hydraulic puller sets designed for removing and installing press-fitted or heat-fitted parts. Three configurations are available: 3-Grip puller sets (for solid parts), Crosshead puller sets (for multi-segmented parts like bearings), and Multi-purpose puller sets (combination of both). All parts are manufactured from high quality drop-forged steel. Capacities span 20 to 50 tonnes (with crosshead variants offering 10, 20 and 25 tonnes effective pulling force).
Professional puller sets with hollow-cylinder hydraulics
Yale describes the YHP as designed for removing and installing press-fitted or heat-fitted parts, eliminating time-consuming and costly repairs by avoiding parts damage and reducing machine down-times. The complete sets are supplied ready to use and include all necessary components: hollow cylinder (Yale YCS series), hydraulic hand pump, pressure gauge (to control the pulling force) and 2 metre hydraulic hose with quick connect coupler.
Suitable Applications
Per Yale: 3-Grip sets for solid parts (gears, belt pulleys, sprockets, flywheels, couplers, shafts, axles). Crosshead sets for multi-segmented parts (ball bearings, roller bearings). Multi-purpose sets combine both for universal application. Yale supplies sets in storage cases.
Tools, pumps and hoses must share pressure rating and coupler type. Confirm all three before ordering rather than discovering the mismatch on site.

Frequently Asked Questions
Q: 3-Grip, Crosshead, or Multi-purpose?
Yale specifies: 3-Grip for solid parts (gears, pulleys, flywheels, couplers). Crosshead for multi-segmented parts (ball bearings, roller bearings) - includes bearing puller attachment and bearing cup puller. Multi-purpose universal kits include both.
Q: Can 3-Grip be used as 2-jaw?
Yes. Yale specifies the 3-Grip puller sets can be used as both 3-jaw and 2-jaw puller.
Q: What's the difference between YHP and BMZ?
Both are Yale hydraulic puller ranges. BMZ uses YS solid-piston cylinders (10/15/23 t); YHP uses YCS hollow cylinders (20/30/50 t). YHP offers higher capacity and the hollow cylinder design suits crosshead/bearing-puller configurations.
