Part Name: Dozer Dual Tilt Hydraulic Cylinder Head Assembly

Technical Specifications: Cylinder Application: Dual Tilt Cylinder / Cylinder Bore: 235.00 mm / Stroke: 241.00 mm / Weight: ~49.5 kg / Hydraulic Cylinder Head Component

Compatible Machinery: Caterpillar Heavy Track-Type Tractors / Dozers (D10N, D10R, D10T, D10T2 series)

What It Does:

Serves as the hydraulic cylinder head assembly (gland) mounted on the dual tilt hydraulic cylinder of Caterpillar D10N, D10R, D10T, and D10T2 series heavy track-type tractors (dozers). It seals the front end of the cylinder barrel while guiding and supporting the reciprocating movement of the piston rod. Housing precision rod seals, buffer rings, wiper seals, and wear bands, it retains high-pressure hydraulic fluid inside the cylinder and prevents external contamination.

Importance:

Essential for ensuring internal pressure containment, zero fluid leakage, and proper rod alignment during heavy dozing and blade tilt operations. Precision-machined from high-strength forged/solid steel, this 49.5 kg head assembly effectively withstands severe lateral loads, dynamic bending stress, and hydraulic pressure spikes during mining and earthmoving tasks, while high-grade seal grooves prevent fluid bypass and extend total cylinder service life.
