Brand New ZF 0501335111 Heavy Equipment Support Ring
The ZF 0501335111 (0501.335.111) Support Ring (Ring-Support / Backup Ring) is a genuine OEM structural sealing component engineered for heavy equipment transmissions, hydraulic control blocks, axles, and powershift drive systems manufactured by ZF Friedrichshafen AG.
Drivetrain & Axle Applications
· Differential & Carrier Hub Groups: Provides structurally rigid backing for specialized radial seals or sealing rings inside the main differential unit.
· Planetary Rigid Axles: Commonly found in heavy-load machinery steering axles (LENKACHSE), rigid drive axles, and wheel hubs.
Thank you for choosing SPARKLING MACHINERY.
The ZF 0501335111 support ring is engineered from high-strength, wear-resistant polymers (such as PTFE or reinforced polyamide) to support primary elastomeric seals. Placed adjacent to an O-ring or hydraulic seal within its mounting groove, it closes the clearance gap to prevent the rubber seal from extruding or tearing when subjected to intense pressure spikes and thermal expansion within ZF drive assemblies.
