BOCLAIN — Low-Speed High-Torque Hydraulic Motor & Rotary Drive Specialist in Ningbo, China
BOCLAIN does not focus on standard pumps or cylinders; its core is the rotating output side of hydraulics — motors that turn pressure flow into high torque at low speed.
With radial piston, ball-piston, five-star and orbit motor platforms, BOCLAIN supports equipment makers that need slewing, tracking, winching, milling or wheel-drive functions. Customers typically choose BOCLAIN for Poclain/Rexroth-style interchange options, custom shafts/flanges/brakes and integrated motor + planetary reducer packages.
