Parker TG-0320-0500 Guide Wear Ring 32-50mm

The Parker TG-0320-0500 is a filled-PTFE / fabric guide (wear) ring for 32-50 mm guidance from the Parker Hannifin Seal Group, the world authority on hydraulic cylinder sealing. Parker Hannifin is the largest motion and control technology company globally, and its Engineered Materials Group manufactures the rod seals, piston seals, wipers and guide rings that protect hydraulic cylinders in the most demanding mobile and industrial service. The TG-0320-0500 is engineered to seal the high system pressures, side loads and contamination found in Saudi Arabian hydraulic equipment, from oilfield and construction machinery to fixed industrial presses. Razz Middle East stocks the TG-0320-0500 in Jeddah, Riyadh and Dammam for 24-48 hour delivery to ARAMCO, SABIC, SWCC, MAADEN and NEOM project sites, ensuring cylinders return to service quickly during overhaul.

Seal Design & Material Engineering

The TG guide ring is supplied as a cut-to-length wear tape in filled PTFE or phenolic fabric, providing low-friction bearing support that absorbs transverse loads and keeps the sealing clearance gap within Parker limits. The TG-0320-0500 is profiled to convert system pressure into a controlled, self-energising sealing contact: at low pressure the elastomer's interference provides the static seal, while rising system pressure increases the contact force so the seal remains leak-tight across the full operating range without excessive friction or stick-slip. Parker's compounds resist the thermal and oxidative ageing that destroys generic seals in 50 C-plus Gulf ambient temperatures, and the dynamic surfaces are finished to minimise wear against the cylinder bore or rod. Material selection, profile geometry and surface finish are matched to the duty so the seal delivers long, predictable life rather than premature extrusion, nibbling or hardening. Every seal is manufactured to Parker's controlled tolerances and traceable lot quality, giving the consistency that maintenance engineers depend on during planned cylinder rebuilds.

Dimensional Data & Housing Requirements

Guide bore range: 32-50 mm Tape thickness: per Parker TG wear-ring series Fit: cut-to-length wear ring The housing must be machined to Parker's published groove and bore tolerances, with correct lead-in chamfers and edge radii to prevent damage during seal installation. Dynamic surface finish should typically be 0.1-0.4 micron Ra on the sealing surface with a 0.05-0.2 micron Ra finish on the running counter-surface; bore and rod surfaces that are too rough cause rapid wear, while surfaces that are too smooth prevent the formation of the lubricating film the seal needs. Extrusion-gap control is critical: as system pressure rises the radial clearance between rod/piston and housing must be held within Parker's limits, with anti-extrusion back-up rings or guide rings added where required. Razz can supply the full Parker installation and groove-design data for the TG-0320-0500.

Applications in Saudi Arabia

Across the Kingdom the Parker TG-0320-0500 is fitted in the hydraulic cylinders that power critical operations. In Saudi Aramco drilling, workover and process facilities the guide ring / wear ring seals the cylinders of pipe-handling equipment, blowout-preventer actuators and valve operators, where leak-tight performance and long service intervals are essential in remote desert and offshore locations. MAADEN mining and minerals operations rely on it in excavator, loader, crusher and conveyor-tensioning cylinders subjected to shock loading, dust and continuous duty. SABIC, Sadara and Petro Rabigh petrochemical plants use the TG-0320-0500 in press, baler and material-handling cylinders, while SWCC and ACWA Power desalination facilities fit it in high-pressure pump and valve-actuation cylinders. Construction and infrastructure contractors at NEOM, Red Sea Global and across Riyadh deploy it in mobile cranes, excavators, concrete pumps and tunnel-boring equipment, where the TG-0320-0500 must withstand Gulf heat, dust ingress and high duty cycles. Standardising on genuine Parker seals during cylinder rebuilds reduces repeat failures and extends mean time between overhauls, cutting the total cost of ownership of the Kingdom's hydraulic fleet.

Selection Guide — Temperature, Media & Pressure

Guide rings carry the side loads between rod and bore or piston and bore, preventing metal-to-metal contact and maintaining the extrusion gap that the seals depend on. For standard mineral-oil hydraulics up to +100 C, polyurethane and NBR-based seals offer the best balance of wear resistance and cost. Where temperatures exceed +100 C or fire-resistant and synthetic fluids are used, FKM and PTFE-based seals are specified. PTFE-faced seals and guide rings minimise friction and eliminate stick-slip in servo-controlled and slow-moving cylinders. For high-pressure service above 250 bar, correct extrusion-gap control and back-up/guide rings are essential to prevent the seal extruding into the clearance gap. Razz engineers can cross-reference the TG-0320-0500 against your cylinder dimensions, fluid and pressure to confirm the correct seal package.
