Timken HR30205J Tapered Roller Bearing

Timken HR30205J Tapered Roller Bearing — High-Performance Radial Load Bearing for Saudi Arabia

The Timken HR30205J is a single-row tapered roller bearing in the 30200 metric series, designed for combined radial and axial load applications in industrial machinery, gearboxes, and wheel hub assemblies. The HR30205J is one of the most widely specified Timken tapered bearings in Saudi Arabian industrial maintenance, repair, and operations (MRO) supply — found in pump shafts, conveyor head drums, and electric motor轴承座 in processing plants across the Kingdom.

Saudi Arabia's industrial sector — from Aramco's upstream wellhead pumps to SABIC's Jubail polymerization reactors — depends on Timken HR30205J for shaft support in environments where heavy radial loads combine with axial thrust from gearbox helical gears, pump impellers, and belt drives. The tapered geometry allows the bearing to handle both simultaneously, eliminating the need for separate radial and thrust bearings.

Key Features for Saudi Applications

Timken Precision Steel: Case-hardened carbon chromium steel provides excellent fatigue resistance under Variable Loading conditions common in Saudi Arabian pump and compressor drives — where process pressure fluctuations create irregular bearing loads on pump shafts.

Optimized Contact Geometry: The 14.25mm (T) crown-flange geometry provides superior load distribution compared to conventional bearings, reducing edge stress at the cup/cone interface — critical in high-torque gearbox applications at Saudi Aramco gas compressor stations.

Pressed Steel Cage: Pin-riveted pressed steel cage maintains roller guidance under shock loads from hydraulic系统 in Saudi Arabian injection pump applications.

Wide Temperature Range: -40°C to +120°C operating range covers Saudi winter temperatures at Aramco Khurais (-15°C night) through summer surface temperatures in Dhahran.

Applications in Saudi Arabia

Gearboxes: SABIC and Aramco contractors specify HR30205J in intermediate shaft positions of parallel shaft gearboxes used in air separation units (ASUs) at Jubail and Yanbu industrial complexes.

Pumps: Centrifugal pump shafts in SWCC desalination plants and Aramco water injection systems use HR30205J as a locating bearing — providing precise shaft location while handling combined radial and axial loads.

Conveyor Systems: Belt conveyor head and tail drums at Saudi cement plants (Yanbu Cement, Al Riyadh Cement) use HR30205J in pillow block housings for the high radial loads from heavy material transport.

Electric Motors: NEMA and IEC frame electric motors supplied to Saudi industrial plants commonly use HR30205J as the drive-end bearing in C-face and D-flange motor configurations.

Frequently Asked Questions

Q1: What is the Timken HR30205J price in Saudi Arabia? Pricing depends on quantity, packaging, and certification requirements (Aramco 9A inspection certificate or equivalent). Contact RAZZ at sales@razz.sa for competitive Saudi MRO pricing.

Q2: What is the equivalent SKF bearing to HR30205J? The SKF equivalent is 30205 J2/Q. The Timken HR30205J meets ISO 355 equivalent dimensions and is fully interchangeable for industrial MRO applications in Saudi Arabia.

Q3: What lubrication is recommended for HR30205J? Timken recommends grease lubrication (Lithium-complex EP grease) for speeds up to 8,500 rpm. For oil bath lubrication, the oil level should be maintained at the center of the lowest rolling element.

Q4: Can HR30205J be used in high-temperature Saudi pump applications? Yes, up to +120°C continuous. For higher temperatures, consult RAZZ's technical team for high-temperature variant (suffix -TN or HT) with expanded temperature range.

Q5: What is the Timken HR30205J availability from RAZZ in Saudi Arabia? RAZZ maintains stock of HR30205J in Riyadh and Dammam warehouses. Standard delivery 1–3 business days. Project quantities and annual MRO contracts available — contact RAZZ for terms.
