Construction and Design

The 5306 2RS C3 features two rows of precision steel balls arranged to support combined radial and axial loads in both directions. This design provides greater load capacity and rigidity than a comparable single-row bearing.

Double rubber seals (2RS) protect the rolling elements from dust, moisture and contaminants while retaining factory-filled grease. The increased C3 internal clearance compensates for thermal expansion during high-speed or high-temperature operation. The precision-engineered polyamide cage reduces friction, operating temperature and overall bearing weight, contributing to quieter operation and extended service life.

Material Properties

The bearing rings and balls are manufactured from premium high-carbon bearing steel, while the cage is produced from durable engineering polyamide.

Key advantages include:

• high radial and axial load capacity
• polyamide cage for reduced friction
• double-sided 2RS sealing
• increased C3 internal clearance
• excellent wear resistance
• smooth and quiet operation
• extended service life

FAQ

What type of bearing is the PFI 5306 2RS C3?

It is a double row angular contact ball bearing designed to support combined radial and axial loads in both directions.

What does the 2RS designation mean?

2RS indicates rubber seals on both sides of the bearing that protect against dust, moisture and contaminants while retaining lubricant.

What is the purpose of C3 internal clearance?

C3 indicates increased internal clearance, allowing reliable operation at higher temperatures and rotational speeds.

Why is a polyamide cage used?

A polyamide cage reduces friction, lowers operating temperatures, decreases weight and improves high-speed performance.

Where is the PFI 5306 2RS C3 commonly used?

It is widely installed in electric motors, industrial gearboxes, pumps, compressors, conveyors and power transmission equipment.
