Product Features & Applications

PN 860103346 / Drawing 79500813A​ is a XCMG-specified oil seal housing (seat), finished to RZ-type sealing geometry per OEM drawing. It's the machined carrier that holds the rotary shaft seal in place — typically mounted on axle hubs, travel/swing reducers, or hydraulic pump/motor interfaces on XCMG export machines. Note: this is the housing, not the oil seal itself​ — order both together to avoid jobsite comebacks.

The "oil seal housing" (a.k.a. seal seat) is a machined or cast mounting flange that centers and locks the rotary shaft seal onto the bore where a rotating shaft penetrates the casing. On XCMG export machines, the 79500813A-type seat is typically found on axle hubs, travel/slew reducers, and hydraulic pump/motor end covers. The suffix RZ​ indicates the seating face is machined to accept an RZ-type non-contact lip seal​ — steel-backed NBR, low-friction, dust-proof, suited for higher shaft speeds (think bearing-style RZ, not heavy-waterproof RS).

⚠️ Important for buyers: This PN is the metal housing/seat, NOT the rubber oil seal. If a jobsite is fixing a leak, they usually need boththe housing and the matching rotary shaft seal. Quoting them as a "Seal + Housing Kit" cuts after-sales comebacks significantly.
