Key characteristics of the 2RS configuration

Dual-contact rubber seals

The 2RS sealing system protects the bearing interior by helping keep grease inside while limiting contaminant intrusion.

Improved lubrication retention

Sealed construction supports longer lubricant life and more stable operating conditions.

Lower maintenance exposure

Because the internal grease remains protected, maintenance intervals may be reduced in many applications.

Hardened chrome steel structure

Chrome steel provides durability, wear resistance, and dependable operation for continuous rotational use.

2RS vs ZZ bearing versions

1604-2RS

Best suited for:

• Dust-prone environments
• Moderate humidity exposure
• Maintenance-sensitive systems
• Applications requiring grease protection

1604-ZZ

Better suited for:

• High-speed rotation
• Lower rotational drag
• Dry operating environments
• Systems prioritizing RPM efficiency

The 2RS version emphasizes sealing protection, while ZZ versions prioritize rotational speed and reduced friction.

Installation and usage recommendations

For optimal service life:

• Keep installation surfaces clean
• Avoid impact loading during mounting
• Use proper fitting tools
• Ensure shaft and housing alignment
• Store bearings in dry environments before installation
