NSK Deep Groove Ball Bearing 6205-2Z

NSK 6205-2Z Deep Groove Ball Bearing — 25mm Bore, Double Shielded, for Saudi Industrial Applications

The NSK 6205-2Z is a 25mm bore deep groove ball bearing with two metal shields (2Z), providing protection against dust and debris in both directions. As one of the most widely used bearing numbers in industrial machinery worldwide, the 6205-2Z is specified across Saudi Arabia's pump, motor, conveyor, and gearbox applications — from SABIC's Jubail chemical plants to municipal water pumping stations in Riyadh and Jeddah.

NSK's precision-controlled steel and cage geometry delivers smooth operation at speeds up to 12,000 rpm. The 6205-2Z's 52mm OD fits the standard housing bore used by virtually every industrial equipment manufacturer — making it the go-to replacement bearing for maintenance crews at Saudi Aramco, SWCC, and private sector factories alike.

Key Features for Saudi Applications

Double Shielded (2Z): Metal shields on both sides prevent contaminant ingress — critical for outdoor motor applications, dusty desert environments, and pump installations in Saudi coastal cities where salt air accelerates bearing failure.

High-Speed Rating: C3 clearance with high-grade steel enables operation up to 12,000 rpm — suitable for electric motor shafts, fan drives, and high-speed conveyor idlers.

Interchangeability: The 6205-2Z is dimensionally identical across all major manufacturers (SKF, FAG, TIMKEN, NTN) — simplifying procurement and reducing downtime for maintenance teams.

Applications in Saudi Arabia

SABIC Pump Assemblies: The 6205-2Z is the standard bearing in process water pumps and chemical transfer pumps at Jubail and Yanbu SABIC facilities.

SWCC Desalination Plant Motors: Horizontal and vertical pump motors at SWCC plants in Jeddah and Jubail use 6205-2Z as the standard bearing for motor shafts.

Jeddah Port Conveyor Systems: The Jeddah Islamic Port's container conveyor systems and stacking cranes use hundreds of 6205-2Z bearings.

Frequently Asked Questions

Q1: What is the NSK 6205-2Z price in Saudi Arabia? Contact RAZZ at sales@razz.sa for competitive pricing. Stocked in Jeddah and Dammam warehouses with same-day dispatch. Bulk pricing for project quantities (100+ units).

Q2: How do I identify the correct bearing for my application? Measure the bore diameter (inner ring), outside diameter (outer ring), and width. The 6205-2Z is standardized: 25mm bore × 52mm OD × 15mm wide.

Q3: What is the difference between 2Z (double shielded) and 2RS (double sealed)? 2Z has metal shields — better for dust protection at high speeds. 2RS has rubber seals — better for preventing grease loss and blocking moisture. For Saudi coastal environments (Jeddah, Dammam, Jubail), 2RS is preferred for its moisture barrier properties.

Q4: Can NSK 6205-2Z be used in high-temperature applications? Standard 6205-2Z operates to +120°C. For higher temperatures, specify the NSK 6205-2ZC3 with C3 clearance and high-temperature grease — available on request from RAZZ.
